Recent debates in cognitive science revolve around a core concept of cognition beyond an anthropocentric perspective. Researchers have aimed at recreating evolutionarily inspired solutions equivalent to naturebased faculties in organisms. By using model organisms, scientists have begun to formulate a consensus view on what might be called basal cognition based on nervous system of simple organisms like sea slugs, flies, and flat worms. Noteworthy, Koshland (1983) pioneered this idea and traced cognition down to the ‘base’ of the phylogenetic tree by emphasizing analogies of the bacterial chemosensory system and information processing to those in neurons of complex organisms. Taking up this idea, we have argued that evolutionary ‘recent’ specializations of the nervous system have adopted cellular processes that have derived from ancient and fundamental cell survival processes (Sarto-Jackson and Tomaska, 2016). We will provide arguments for using yeast as a model system of basal cogni...

Building from the ideas of existential theorists [1, 2], Terror Management Theory (TMT) addresses the existential anxiety associated with people’s thoughts about their inevitable death. The theory is founded on two tenets: (a) that a primary instinct for humans is to preserve themselves; and (b) that humans are able to comprehend that they will ultimately fail at their goal of self-preservation. The clash between one’s self-preservation instinct and the outlook of one’s inevitable demise is, therefore, a potential source of existential fright and terror. TMT has focused on exploring how people keep these existential fears at bay. TMT proposes that people usually attempt not to think about their mortality to avoid being overwhelmed by this conflict. However, once they are reminded of their mortality, they feel existentially vulnerable. In order to avoid becoming overwhelmed by their mortal predicament, they activate two consecutive defense processes: They first respond by (a) proxima...

The role of narratives in clinical practice has long been underappreciated. This disregard is largely due to an overemphasis on reductionist interpretations of disease causes based on the primacy of the medical model of disease. This way of thinking has led to decontextualizing symptoms of disorders from patients’ lives. More recently, however, healthcare professionals have turned towards a biopsychosocial model that reintroduces sociocultural and psychosocial aspects into clinical diagnosis and treatment. To this end, narrative approaches have been increasingly explored as alternative diagnostic and therapeutic tools. Central to the narrative approach is the avoidance of pathologizing language that usually focuses on deficiencies.

Comparative models of GABA(A) receptors composed of alpha1 beta3 gamma2 subunits were generated using the acetylcholine-binding protein (AChBP) as a template and were used for predicting putative engineered cross-link sites between the alpha1 and the gamma2 subunit. The respective amino acid residues were substituted by cysteines and disulfide bond formation between subunits was investigated on co-transfection into human embryonic kidney (HEK) cells. Although disulfide bond formation between subunits could not be observed, results indicated that mutations studied influenced assembly of GABA(A) receptors. Whereas residue alpha1A108 was important for the formation of assembly intermediates with beta3 and gamma2 subunits consistent with its proposed location at the alpha1(+) side of GABA(A) receptors, residues gamma2T125 and gamma2P127 were important for assembly with beta3 subunits. Mutation of each of these residues also caused an impaired expression of receptors at the cell surface....

The anxiolytic, anticonvulsant, muscle-relaxant, and sedative-hypnotic effects of benzodiazepine site ligands are mainly elicited by allosteric modulation of GABA receptors via their extracellular αx+/γ2- ( x = 1, 2, 3, 5) interfaces. In addition, a low affinity binding site at the homologous α+/β- interfaces was reported for some benzodiazepine site ligands. Classical benzodiazepines and pyrazoloquinolinones have been used as molecular probes to develop structure-activity relationship models for benzodiazepine site activity. Considering all possible α+/β- and α+/γ- interfaces, such ligands potentially interact with as many as 36 interfaces, giving rise to undesired side effects. Understanding the binding modes at their binding sites will enable rational strategies to design ligands with desired selectivity profiles. Here, we compared benzodiazepine site ligand interactions in the high affinity α1+/γ2- site with the homologous α1+/β3- site using a successive mutational approach. We ...

GABA-A receptors are the major inhibitory transmitter receptors in the brain and the site of action of many clinically important drugs. CGS 9895 and many other pyrazoloquinolinones are high affinity null modulators at the benzodiazepine (Bz) binding site and at higher concentrations also modulate the receptors via the α+β- interface. To gain insights into the interactions of CGS 9895 with both binding sites, we used our homology models to select γ2- side amino acid residues important for Bz binding and to incorporate them into the β3- side by site directed mutagenesis. These mutated β3 subunits were co-expressed with α subunits. The recombinant receptors were investigated by the two electrode voltage clamp method in Xenopus laevis oocytes and by radioligand binding assays. With only four mutations we were able to introduce a high affinity binding site for CGS 9895 into αβ3 receptors. Furthermore, GABA currents of several recombinant αβ3(mut) receptors could be modulated by the tested pyrazoloquinolinones ...

Consequently, psychoeducational narratives enhance the patient's competence in coping with a physical or mental illness and re-contextualizing symptoms, and prompt an increased compliance with therapies.

If we want to learn how to deal with the COVID-19 pandemic, we have to embrace the complexity of this global phenomenon and capture interdependencies across scales and contexts. Yet, we still lack systematic approaches that we can use to deal holistically with the pandemic and its effects. In this Discussion, we first introduce a framework that highlights the systemic nature of the COVID-19 pandemic from the perspective of the total environment as a self-regulating and evolving system comprising of three spheres, the Geosphere, the Biosphere, and the Anthroposphere. Then, we use this framework to explore and organize information from the rapidly growing

Die Gehirnentwicklung eines Säuglings ist bei der Geburt noch nicht
abgeschlossen. Sie erfolgt postnatal durch neuroplastische Prozesse, die das frühkindliche Gehirn besonders lernfähig machen und soziale Bindung forcieren. Neuroplastizität erhöht aber auch die Vulnerabilität des Gehirns in Stresssituationen, ausgelöst durch negative Umwelteinflüsse, Vernachlässigung und Misshandlung. Toxischer Stress kann in weiterer Folge zu kognitiven Schäden und langfristig verstärkten Angstreaktionen führen.

At the time of birth, infant brain development is by no means complete. Neuroplastic processes that occur postnatally provide the child’s brain with a profound adaptedness to learn and form social bonds. Neuroplasticity,
however, also increases the brain’s vulnerability to stress situations triggered by negative environmental impact, neglect and abuse. Subsequently, toxic stress can lead to cognitive impairment and long-term, heightened anxiety.

Evolutionary epistemology (EE) has experienced a continuous rise over the last decades. Important new theoretical considerations and novel empirical findings have been integrated into the existing framework (Gontier and Bradie 2018). In this paper, I would like to suggest three lines of research that I believe will significantly contribute to further advance EE: (1) ontogenetic considerations, (2) key ideas from cognitive biology, and (3) the framework of the Extended Evolutionary Synthesis. (1) EE, in particular the program of the evolution of epistemological mechanisms (EEM), seeks to provide a phylogenetic account of the generation of cognitive processes underlying knowledge creation (Bradie and Harms 2017). Traditionally, EE and EEM have been oriented towards an account of evolutionary theory that mainly drew from the tenets of the Modern Synthesis. The Modern Synthesis largely dismisses ontogenetic processes and considers them irrelevant for evolutionary explanations. If anything, the role of development in evolution is believed to be that of a constraint. There is, however, ample evidence for a tight intertwinement of developmental and evolutionary processes. Organisms employ their cognitive apparatus to interact with the environment in order to achieve a fully functioning perceptual and cognitive nervous system. Also, ontogeny provides generative potentials to enable variations that natural selection can act upon. EEM's agenda may, therefore, strongly benefit from bringing together ontogenetic and phylogenetic approaches. To grapple with this challenge, an alternative vision of the evolutionary theory termed Extended Evolutionary Synthesis (Pigliucci and Müller 2010) could be used. This extended evolutionary theory explores relationships between the processes of individual development and phenotypic change during evolution (i.e., EvoDevo) and can provide a more suitable framework for EEM to draw from. (2) In recent years, cog-nitive biology has gained momentum as an independent research field. Cognitive biology builds on the concepts of EEM and understands knowledge as a biogenic phenomenon. Its main objective is also the formulation of substantiated interrelations between cognition and * Isabella Sarto-Jackson 1 3 evolution but it focuses on cognitive functionality at all levels of biological organization. It thus employs a "vertical" approach that encompasses nested hierarchies which span from single molecules, cells, and tissues to the organismal level, communities, and societies. In contrast to cognitive biology, EEM is here understood to adopt a "horizontal" approach that focuses on phylogenetic explanations of cognition and knowledge acquisition (Kovac 2006). Linking EEM with the key ideas of cognitive biology could make EEM's research program stronger as it can more easily accommodate phylogenetic and ontogenetic questions within a hierarchical, multilevel perspective. This is of particular importance for a more comprehensive account of cognition since living systems are subject to context-dependent causal influences from different organizational levels. (3) In addition to EEM, there is a second program of EE. This program has been labeled evolutionary epistemology of theories (EET) and understands the increase in human knowledge, such as scientific theories, as natural-istic accounts of evolution. Both, EEM and EET initially drew from the core concepts of the Modern Synthesis. Several scholars have severely criticized the analogies made between EET and the Neo-Darwinian key processes of evolution. In particular processes of random mutation, the rate of variation, natural selection as the unique driving force, and the adap-tationist agenda are believed to reveal disanalogies. In contrast to the Modern Synthesis, the Extended Evolutionary Synthesis not only recognizes developmental processes but also ecological interactions and systems dynamics as well as social and cultural evolutionary reciprocity as important evolutionary processes. Concepts of the Extended Evolutionary Synthesis are therefore expected to be more fruitful for re-conceptualizing parallels between scientific theorizing and biological evolution.

The anxiolytic, anticonvulsant, muscle-relaxant and sedative-hypnotic effects of benzodiazepine site ligands are mainly elicited by allosteric modulation of GABAA receptors via their extracellular αx+/γ2− (x = 1,2,3,5) interfaces. In addition, a low affinity binding site at the homologous α+/β− interfaces was reported for some benzodiazepine site ligands. Classical benzodiazepines and pyrazoloquinolinones have been used as molecular probes to develop structure activity relationship models for benzodiazepine site activity. Considering all possible α+/ β− and α+/ γ− interfaces, such ligands potentially interact with as many as 36 interfaces, giving rise to undesired side effects. Understanding the binding modes at their binding sites will enable rational strategies to design ligands with desired selectivity profiles. Here, we compared benzodiazepine site ligand interactions in the high affinity α1+/γ2− site with the homologous α1+/β3− site using a successive mutational approach. We incorporated key amino acids known to contribute to high affinity benzodiazepine binding of the γ2− subunit into the β3− subunit,
resulting in a quadruple mutant β3(4mut) with high affinity flumazenil (Ro 15-1788) binding properties. Intriguingly, some benzodiazepine site ligands displayed positive allosteric modulation in the tested recombinant α1β3(4mut) constructs while diazepam remained inactive.
Consequently, we performed in silico molecular docking in the wildtype receptor and the quadruple mutant. The results led to the conclusion that different benzodiazepine site ligands seem to use distinct binding modes, rather than a common binding mode. These findings provide structural hypotheses for the future optimization of both benzodiazepine site ligands, and ligands that interact with the homologous α+/β− sites.

The human brain is equipped with physiological, neural, and cognitive capacities that enable it to respond flexibly to ever-changing natural and social conditions. This capacity of the brain to reorganize itself, called neuroplasticity, is particularly marked in childhood. The high malleability of the brain at this stage provides the basis for wide-ranging learning, but leaves it vulnerable to negative environmental and social factors. Neuroplastic events that occur in response to abusive or neglecting environments can strongly interfere with the adaptive shaping of neural pathways between the prefrontal cortex and the limbic system, compromising judgment and self-control. Traumatic experiences during development can also have other effects on brain plasticity that are mediated by epigenetic mechanisms, and these effects can impair the developing oxytocin system, adversely affecting attachment and bonding. Mature individuals seek out niches that match the internal mental structures shaped during their early years, and will even alter the environment to make it match the internal structures. In the case of those who suffered childhood abuse, this can lead to maltreatment of the next generation. Addressing the societal challenge of child abuse and maltreatment requires broad interdisciplinary endeavors, uniting neuroscientists and social education workers to break the vicious circle.

There is a conceptual crisis in the biomedical sciences  that  is  particularly  salient  in  psychopathology research. Underlying the crisis is a controversy that pertains to the current medical model of disease that largely draws from causal-mechanistic explanations. The bedrock of this model is the analysis of biological part-dysfunctions that aims at unequivocally defining a pathological condition and demarcating it from its neighboring entities. This endeavor has led to a quest for physiological, biochemical, and genetic signatures. Yet, so far there is little evidence for reliable biomarkers for any mental disorder. The contemporary biomedical paradigm largely ignores historical, dynamic, and system-level aspects—a view that has contributed much to the conceptual disjunction of the patient as a person from his/her disease. Notwithstanding the impressive progress in the biomedical sciences, increasingly more critics question whether the constituting framework is sufficient to convey a comprehensive understanding of illnesses, especially mental illnesses. Thus, the medical model urgently requires an update. But rather than revamping it by methodological advancements, it will be necessary to critically review its philosophical roots. The most problematic issues that require reworking are: the preponderance of the biostatistical theory; the undue decoupling of physiological from evolutionary explanations of function; the clinging to the Modern Synthesis (if etiological aspects are ever considered); and the neglect of dynamic and system-level properties. The proposed overhaul requires the heeding of historical explanations that draw from the Extended Evolutionary Synthesis as well as systems biology approaches for tackling multilevel and dynamic phenomena of complex systems.

Our primary goal in this article is to discuss the cross-talk between
biological and cultural factors that become manifested in the individual brain development, neural wiring, neurochemical homeostasis, and behavior. We will show that behavioral propensities are the product of both cultural and biological factors and an understanding of these interactive processes can provide deep insights into why people behave the way they do. This interdisciplinary perspective is offered in an effort to generate dialog and empirical work among scholars interested in merging aspects of anthropology and neuroscience, and anticipates that
biological and cultural anthropology converge. We discuss new theoretical developments, hypothesis-testing strategies, and cross-disciplinary methods of observation and data collection. We believe that the exigency of integrating anthropology and the neurosciences is indisputable and anthropology’s role in an emerging interdisciplinary science of human behavior will be critical because its focus is, and
has always been, on human biological and cultural systems.

Formation, maintenance, and activity of excitatory and inhibitory synapses are essential for neuronal network function. Cell adhesion molecules (CAMs) are crucially
involved in these processes. The CAM neuroplastin-65 (Np65) highly expressed during periods of synapse formation and
stabilization is present at the pre- and postsynaptic membranes. Np65 can translocate into synapses in response to electrical stimulation and it interacts with subtypes of GABAA receptors in inhibitory synapses. Here, we report that in the murine hippocampus and in hippocampal primary culture, neurons of the CA1 region and the dentate gyrus (DG) express high Np65 levels while expression in CA3 neurons is lower. In
neuroplastin-deficient (Np-/-) mice the number of excitatory synapses in CA1 and DG, but not CA3 regions is reduced. Notably this picture is mirrored in mature Np-/- hippocampal cultures or in mature CA1 and DG wild-type (Np+/+) neurons treated with a function-blocking recombinant Np65-Fc extracellular fragment. Although the number of GABAergic synapses was unchanged in Np-/- neurons or in mature Np65-Fc-treated Np+/+ neurons, the ratio of excitatory to
inhibitory synapses was significantly lower in Np-/- cultures. Furthermore, GABAA receptor composition was altered at inhibitory synapses in Np-/- neurons as the α1-to-α2 GABAA
receptor subunits ratio was increased. Changes of excitatory and inhibitory synaptic function in Np-/- neurons were confirmed evaluating the presynaptic release function and using
patch clamp recording. These data demonstrate that Np65 is an important regulator of the number and function of synapses in the hippocampus.

GABAA receptors are chloride ion channels that can be opened by GABA, the most important inhibitory transmitter in the CNS. In the mammalian brain the majority of these pentameric receptors is composed of two a, two b and one g subunit. To achieve the correct order of subunits around the pore, each subunit must form specific contacts via its plus (+) and minus (–) side. To identify a sequence on the b3 subunit important for assembly, we generated various full-length or truncated chimeric b3 constructs and investigated their ability to assemble with a1 and g2 subunits. It was demonstrated that
replacement of the sequence b3(76–89) by the homologous a1
sequence impaired assembly with a1 but not with g2 subunits
in a1b3g2-GABAA receptors. Other experiments indicated that
assembly was impaired via the b3(–) side of the chimeric subunit. Within the sequence b3(76–89) the sequence b3(85–
89) seemed to be of primary importance for assembly with a1
subunits. A comparison with the structure of the acetylcholine binding protein supports the conclusion that the sequence b3(85–89) is located at the b3(–) side and indicates that it contains amino acid residues that might directly interact with the (+) side of the neighbouring a1 subunit.

Density gradient centrifugation of native and recombinant
g-aminobutyric acid, type A (GABAA) receptors was used to detect assembly intermediates. No such intermediates could be identified in extracts from adult rat brain or from human embryonic kidney (HEK) 293 cells transfected with a1, b3, and g2 subunits and cultured at 37 °C. However, subunit dimers, trimers, tetramers, and pentamers were found in extracts from the brain of 8–10-day-old rats and from a1b3g2 transfected HEK cells cultured at 25 °C. In both systems, a1, b3, and g2 subunits could be identified in subunit dimers, indicating that different subunit dimers are formed during GABAA receptor assembly. Co-transfection of HEK cells with various combinations of full-length and C-terminally truncated a1 and b3 or a1 and g2 subunits and coimmunoprecipitation with subunit-specific antibodies indicated that even subunits containing no transmembrane domain can assemble with each other. Whereas a1g2, a1Ng2, a1g2N, and a1Ng2N, combinations
exhibited specific [3H]Ro 15-1788 binding, specific [3H]muscimol binding could only be found in a1b3 and a1b3N, but not in a1Nb3 or a1Nb3N combinations. This seems to indicate that a full-length a1 subunit is necessary for the formation of the muscimol-binding site and for the transduction of agonist binding into channel gating.

GABAA receptors are the major inhibitory transmitter receptors
in the CNS. Recombinant GABAA receptors composed of
a1b3g2 subunits have been demonstrated to assemble as pentamers consisting of two a1 , two b3 , and one g2 subunit. Using truncated and chimeric !1 subunits, we identified the a1(80–100) sequence as a major binding site for g2 subunits. In
addition, we demonstrated its direct interaction with g2(91–
104), a sequence that previously has been identified to form the
contact to a1 subunits. The observation that the amino acid
residues a1P96 and a1H101, which can be photolabeled by
[ 3H]flunitrazepam, are located within or adjacent to the a1(80–
100) sequence, indicates that the benzodiazepine binding site
of GABAA receptors is located close to this intersubunit contact.
The observation that !1(80–100) interacts with g2 but not with b3 subunits indicates the existence of an additional b3
binding site on a1 subunits. The preferred alternate use of the
g2 and b3 binding sites in two different a1 subunits of the same
receptor ensures the incorporation of only a single g2 subunit
and thus, determines subunit stoichiometry of a1b3g2 receptors. Distinct binding sites and their alternate use can therefore explain how subunits of hetero-oligomeric transmembrane proteins assemble into a defined protein complex.

Estrogens exert a variety of modulatory effects on the structure and function of the nervous system. In particular, 17 b-estradiol was found to affect GABAergic inhibition in adult animals but its action on GABAergic currents during development has not been elucidated. In the present study, we investigated the effect of 17 b-estradiol on hippocampal neurons developing in vitro. In this model, mIPSC kinetics showed acceleration with age along with increased a1 subunit expression, similarly as in vivo. Long-term treatment with 17 b-estradiol increased mIPSC
amplitudes in neurons cultured for 6e8 and 9e11 DIV and prolonged the mIPSC decaying phase only in the 9e11 DIV group. The time needed for the onset of 17 b-estradiol effect on mIPSC amplitude was approximately 48 h. In the period of 9e11 DIV, treatment with 17 b-estradiol strongly reduced the tonic conductance activated by low GABA concentrations. The effects of 17 b-estradiol on mIPSCs and tonic conductance were not correlated with any change in expression of considered GABAAR subunits (a1e3, a5e6, g2) while a4 and d subunits were at the detection limit. In conclusion, we provide evidence that 17 b-estradiol differentially affects the phasic and tonic components of GABAergic
currents in neurons developing in vitro.

GABAA receptors mediate the action of many clinically important drugs interacting with different binding sites. For some potential binding sites, no interacting drugs have yet been identified. Here, we established a steric hindrance procedure for the identification of drugs acting at the
extracellular a1+b3- interface, which is homologous to the benzodiazepine binding site at the a1+g2- interface. On screening of >100 benzodiazepine site ligands, the anxiolytic pyrazoloquinoline 2-p-methoxyphenylpyrazolo[4,3–c]quinolin-3(5H)-one (CGS 9895) was able to enhance GABA-induced currents a a1b3 receptors from rat. CGS 9895 acts as an antagonist at the benzodiazepine binding site at nanomolar
concentrations, but enhances GABA-induced currents via a different site present at a1b3g2 and a1b3 receptors. By mutating pocket-forming amino acid residues at the a1+ and the b3- side to cysteines, we demonstrated that covalent labeling of these cysteines by the methanethiosulfonate
ethylamine reagent MTSEA-biotin was able to inhibit the effect ofCGS9895. The inhibition was not caused by a general inactivation of GABAA receptors, because the GABA-enhancing effect of ROD 188 or the steroid a-tetrahydrodeoxycorticosterone was not influenced by
MTSEA-biotin. Other experiments indicated that the CGS 9895 effect was dependent on the a and b subunit types forming the interface. CGS9895 thus represents the first prototype of drugs mediating benzodiazepine-like modulatory effects via the a+b- interface of GABAAreceptors. Since such binding sites are present at ab, abg, and abd receptors, such drugs will have a much broader action than benzodiazepines and might become clinical important for the treatment of epilepsy.

!-Aminobutyric acid, type A (GABAA) receptors are ligand-gated chloride channels and are the major inhibitory transmitter receptors in the central nervous system. The majority of these receptors is composed of two a, two b, and one g subunits. To identify sequences important for subunit assembly, we generated C-terminally truncated and chimeric g3 constructs. From their ability to associate with full-length a1 and b3 subunits, we concluded that amino acid sequence g3(70–84) either directly interacts with a1 or b3 subunits or stabilizes a
contact site elsewhere in the protein. The observation that this sequence contains amino acid residues homologous to g2 residues contributing to the benzodiazepine binding site at the a1/g2 interface suggested that in a1b3g3 receptors the sequence !3(70–84) is located at the a1/g3 interface. In the absence of a1 subunits this sequence might allow assembly of b3 with g3 subunits. Other experiments indicated that sequences g3(86–95) and g3(94–107), which are homologous to previously identified sequences important for assembly of g2 subunits, are also important for assembly of g3 subunits. This indicates that during assembly of the GABAA receptor, more than one N-terminal sequence is important for binding to the same neighboring subunit. Whether the three sequences investigated are involved in direct interaction or stabilize other regions involved in intersubunit contacts has to be further studied.

GABAA receptors are the major inhibitory transmitter receptors in the central nervous system. The majority of these receptors is composed of two α, two β and one γ subunit that assemble around an aqueous pore and form an intrinsic chloride ion channel. Using full-length or truncated chimeric subunits it was demonstrated that homologous sequences from different subunit classes, α1(54–68), β3(52–66), and γ2(67–81), are important for assembly of GABAA receptors composed of α1, β3, and γ2 subunits. In addition, evidence was provided that these sequences all are located in topologically homologous regions of the different subunits. Finally, it was demonstrated that the sequences investigated cause a selective assembly with certain subunits only and thus influence subunit arrangement within GABAA receptors.

More than 30 years ago Dan Koshland published an inspirational essay presenting the bacterium as a model neuron (Koshland, Trends Neurosci 6:133–137, 1983). In the article he argued that there are several similarities between neurons and bacterial cells in “how signals are processed within a cell or how this processing machinery can be modified to produce plasticity”. He then explored the bacterial chemosensory system to emphasize its attributes that are analogous to information processing in neurons. In this review, we wish to expand Koshland’s original idea by adding the yeast cell to the list of useful models of a neuron. The fact that yeasts and neurons are specialized versions of the eukaryotic cell sharing all principal components sets the stage for a grand evolutionary tinkering where these components are employed in qualitatively different tasks, but following analogous molecular logic. By way of example, we argue that evolutionarily
conserved key components involved in polarization processes
(from budding or mating in Saccharomyces cervisiae to neurite outgrowth or spinogenesis in neurons) are shared between yeast and neurons. This orthologous conservation of modules makes S. cervisiae an excellent model organism to investigate neurobiological questions. We substantiate this claim by providing examples of yeast models used for studying neurological diseases.

g-Aminobutyric acid, type A (GABAA) receptor a1 subunits
containing a cysteine mutation at a position in the channel
mouth (H109C) surprisingly formed a spontaneous cross-link
with each other in receptors composed of a1H109C, b3, and g2
subunits. Cross-linking of two a1H109C subunits did not significantly change the affinity of [3H]muscimol or [3H]Ro15-1788 binding in a1H109Cb3g2 receptors, but GABA displayed a reduced potency for activating chloride currents. On reduction of the disulfide bond, however, GABA activation as well as diazepam modulation was similar in mutated and wild-type receptors, suggesting that these receptors exhibited the same subunit stoichiometry and arrangement. Disulfide bonds could not be reoxidized by copper phenanthroline after having been reduced in completely assembled receptors, suggesting that cross-linking can only occur at an early stage of assembly. The cross-link of a1H109C subunits and the subsequent transport of the resulting homodimers to the cell surface caused a reduction of the intracellular pool of a1H109C subunits and a reduced formation of completely assembled receptors. The formation of a1H109C homodimers as well as of correctly assembled GABAA receptors containing cross-linked a1H109C subunits could indicate that homodimerization of a1 subunits via contacts located in the channel mouth might be one starting point of GABAA receptor assembly. Alternatively the assembly mechanism might have started with the formation of heterodimers followed by a cross-link of mutated a1 subunits at the heterotrimeric stage. The formation of cross-linked a1H109C homodimers would then have occurred independently in a separate pathway.

g-Aminobutyric acidA (GABA)A receptors are pentameric ligand-gated ion channels that mediate fast inhibition in the central nervous system. Depending on their subunit composition, these receptors exhibit distinct pharmacological properties and differ in their ability to interact with proteins involved in receptor anchoring at synaptic or extrasynaptic
sites. Whereas GABAA receptors containing α1, α2, or α3 subunits are mainly located synaptically where they interact with the sub-membraneous scaffolding protein gephyrin, receptors containing α5 subunits are predominantly found extra-synaptically and seem to interact with radixin for
anchorage. Neuroplastin is a cell adhesion molecule of the immunoglobulin superfamily that is involved in hippocampal synaptic plasticity. Our results reveal that neuroplastin and GABAA receptors can be copurified from rat brain and exhibit a direct physical interaction as demonstrated by coprecipitation
and Förster Resonance Energy Transfer (FRET) analysis in a heterologous expression system. The brain-specific isoform
neuroplastin-65 co-localizes with GABAA receptors as shown in brain sections as well as in neuronal cultures, and such complexes can either contain gephyrin or be devoid of gephyrin. Neuroplastin-65 specifically colocalizes with a1 or a2, but not with a3 subunits at GABAergic synapses. In addition,
neuroplastin-65 also co-localizes with GABAA
receptor a5 subunits at extra-synaptic sites. Down-regulation of neuroplastin-65 by shRNA causes a loss of GABAA receptor a2
subunits at GABAergic synapses. These results suggest that neuroplastin-65 can colocalize with a subset of GABAA receptor
subtypes and might contribute to anchoring and/or confining GABAA receptors to particular synaptic or extra-synaptic sites,
thus affecting receptor mobility and synaptic strength.

Comparative models of GABAA receptors composed of a1b3g2 subunits were generated using the acetylcholine binding protein (AChBP) as a template and were used for predicting putative engineered cross-link sites between the a1 and the g2 subunit. The respective amino acid residues were substituted by cysteines and disulfide bond formation between subunits was investigated on co-transfection into human embryonic kidney (HEK) cells. Although disulfide bond formation between subunits could not be observed, results indicated that mutations studied influenced assembly of GABAA receptors. Whereas residue a1A108 was important for the formation of assembly intermediates with b3 and g2 subunits consistent with its proposed location at the a1(+) side of GABAA receptors, residues g2T125 and g2P127 were important for assembly with b3 subunits. Mutation of each of these residues also caused an impaired expression of receptors at the cell surface. In contrast, mutated residues a1F99C, a1S106C or g2T126C only impaired the formation of receptors at the cell surface when co-expressed with subunits in which their predicted interaction partner was also mutated. These data are consistent with the prediction that the mutated residue pairs are located close to each other.

GABAA receptors are the major inhibitory transmitter receptors in the central nervous system. They are chloride ion channels that can be opened by g-aminobutyric acid (GABA) and are the targets of action of a variety of pharmacologically and clinically important drugs. GABAA receptors are composed of five subunits that can belong to different subunit classes. The existence of 19 different subunits gives rise to the formation of a large variety of distinct GABAA receptor subtypes in the brain. The majority of GABAA receptors seems to be composed of two a, two b and one g subunit and the occurrence of a defined subunit stoichiometry and arrangement in abg receptors strongly indicates that assembly of GABAA receptors proceeds via defined pathways. Based on the differential ability of subunits to interact with each other, a variety of studies have been performed to identify amino acid sequences or residues important for assembly. Such residues might be involved in direct protein-protein interactions, or in stabilizing direct contact sites in other regions of the subunit. Several homooligomeric or hetero-oligomeric assembly intermediates could be the starting point of GABAA receptor assembly but so far no unequivocal assembly mechanism has been identified. Possible mechanisms of assembly of GABAA receptors are discussed in the light of recent publications.

g-Aminobutyric acid type A receptors (GABAARs) in the spinal
cord are evolving as an important target for drug development
against pain. Purinergic P2X2 receptors (P2X2Rs) are also
expressed in spinal cord neurons and are known to cross-talk
with GABAARs. Here, we investigated a possible “dynamic”
interaction between GABAARs and P2X2Rs using co-immunoprecipitation and fluorescence resonance energy transfer (FRET) studies in human embryonic kidney (HEK) 293 cells along with co-localization and single particle tracking studies in spinal cord neurons. Our results suggest that a significant proportion of P2X2Rs forms a transient complex with GABAARs inside the cell, thus stabilizing these receptors and using them for co-trafficking to the cell surface, where P2X2Rs and GABAARs are primarily located extra-synaptically. Furthermore, agonist-induced activation of P2X2Rs results in a Ca2+-dependent as well as an apparently Ca2+-independent increase in the mobility and an enhanced degradation of GABAARs, whereas P2X2Rs are stabilized and form larger clusters. Antagonist-induced blocking of P2XRs results in co-stabilization of this receptor complex at the cell surface. These results suggest a novel mechanism where association of P2X2Rs and GABAARs could be used for specific targeting to neuronal membranes, thus providing an extrasynaptic receptor reserve that could regulate the excitability of neurons. We further conclude that blocking the excitatory activity of excessively released ATP under diseased state by P2XR antagonists could simultaneously enhance synaptic inhibition mediated by GABAARs.

GABAA receptors are ligand-gated chloride channels composed of five subunits that can belong to different subunit classes. The existence of 19 different subunits gives rise to a multiplicity of GABAA receptor subtypes with distinct subunit composition; regional, cellular and subcellular distribution; and pharmacology. Most of these receptors are composed of two a, two b and one g2 subunits. GABAA receptors are the site of action of a variety of pharmacologically and clinically important drugs, such as benzodiazepines, barbiturates, neuroactive steroids, anaesthetics and convulsants. Whereas GABA acts at the two extracellular b+a- interfaces of GABAA receptors, the allosteric modulatory benzodiazepines interact with the extracellular a+g2- interface. In contrast, barbiturates, neuroactive steroids and anaesthetics seem to interact with solvent accessible pockets in the transmembrane domain. Several benzodiazepine site ligands have been identified that selectively interact with GABAA receptor subtypes containing a2bg2, a3bg2 or a5bg2 subunits. This indicates that the different a subunit types present in these receptors convey sufficient structural differences to the benzodiazepine binding site to allow specific interaction with certain benzodiazepine site ligands. Recently, a novel drug binding site was identified at the a+b- interface. This binding site is homologous to the benzodiazepine binding site at the a+g2- interface and is thus also strongly influenced by the type of a subunit present in the receptor. Drugs interacting with this binding site cannot directly activate but only allosterically modulate GABAA receptors. The possible importance of such drugs addressing a spectrum of receptor subtypes completely different from that of benzodiazepines is discussed.

GABAA receptors are the major inhibitory neurotransmitter receptors in the mammalian brain and the target of many clinically important drugs interacting with different binding sites. Recently, we demonstrated that CGS 9895 (2-(4-methoxyphenyl)-2H-pyrazolo[4,3-c]quinolin-3(5H)-one) elicits a strong and subtype-dependent enhancement of GABA-induced currents via a novel drug-binding site at extracellular ax+by- (x=1–6, y=1–3) interfaces. Here, we investigated 16 structural analogues of CGS 9895 for their ability to modulate GABA-induced currents of various GABAA receptor subtypes. Most of the compounds investigated were able to modulate GABA-induced currents of ab and abg receptors to a comparable extent, suggesting that the effect of these drugs is not dependent on the benzodiazepine site of GABAA receptors. Steric hindrance experiments demonstrated that these compounds exert their action predominantly via the ax+by- (x=1–6, y=1–3) interfaces. Whereas some compounds are unselectively modulating a broad range of receptor subtypes, other compounds feature remarkable functional selectivity for the a6b3g2 receptor, or behave as null modulators at some receptor subtypes investigated.
Pyrazoloquinolinones and pyrazolopyridinones represent the first prototypes of drugs exerting benzodiazepine-like modulatory effects via the a+b- interface of GABAA receptors. The discovery of modulators with functional subtype selectivity at this class of binding sites provides a highly useful tool for the investigation of a6b2/3g2 receptor function, and may lead to novel therapeutic principles.

Re-Engineering Philosophy for Limited Beings is about new approaches to many of the big topics in philosophy of science today, but with a very different take. To begin with, we are urged to reject the received Cartesian-Laplacean myths: Descartes’ certainty and Laplace’s computational omniscience. Instead, Wimsatt re-engineers a philosophy for human beings with all their cognitive limitations. His approaches find their starting point in the actual practices of scientists themselves, which he strongly identifies with engineering practices as the source of researchers’ solutions for dealing with a complex world. He aims to construct an understanding of scientific methodology around the central role of reduction. But he dismisses eliminative reductionism in favor of a heuristic-based realist view. Wimsatt’s world is a complex one, and this means that science needs to do away with all the absolute and simple answers, because they do not reflect the world we are living in. A complex world requires the mindset and tinkering of an engineer to uncover its reality. The appropriate response must be heuristics all the way down as we constantly seek out reliable inferences on often shifting ground. To this end, we aim for models and theories that are robust, just as engineers aim to build robust machines. And although errors occur and approaches are fallible, they allow us to continually adapt the heuristics applied and sharpen our perceptions so as to develop more refined tools for investigating and understanding the world.

The human brain has a truly remarkable capacity. It reorganizes itself, flexibly adjusting to fl uctuating environmental conditions – a process called neuroplasticity. Neuroplasticity provides the basis for wide-ranging learning and memory processes that are particularly profuse during childhood and adolescence. At the same time, the exceptional malleability of the developing brain leaves it highly vulnerable to negative impact from the surroundings. Abusive or neglecting social environments, as well as socioeconomic deprivation and poverty, cause toxic stress and complex traumas that can severely compromise cognitive development, emotional processing, self-perception, and executive brain functions. The neurophysiological changes entailed impair emotional regulation, lead to heightened anxiety, and afflict attachment and the formation of social bonds. Neuroplastic changes following severely adverse experiences are not something that a person grows out of and gets over. These experiences alter the neurobiological and
biochemical makeup and cause people to live in an emotionally relabeled world in which the evaluation of any social cue, their behavior, cognition, and state of mind are biased towards the negative. Even more worrying, detrimental neurophysiological consequences are not limited to the traumatized individual but are often transmitted to subsequent generations through a process of social niche construction, thereby creating a vicious cycle. Thus, the making and breaking forces of the brain are epitomized by parents, alloparents, peers, and our socioeconomic niche.
This book expounds on the formative role that the social environment plays in healthy brain development, especially during infancy, childhood, and adolescence. Based on scientific findings, the book advocates for bold measures and responsible stewardship to combat child abuse, maltreatment, and child poverty. By bringing together insights from neuroscience, evolutionary biology, and social education work, it lays out a fact-based, transdisciplinary endeavor that aims at rising to the societal challenge of providing a rewarding perspective to youth at risk. It will be a valuable resource for academics from social education, pedagogy, cognitive science, neuroscience, as well as professionals in the fields of social work, pedagogy, education, child welfare.
