- EXAMPLE 2 Effect of Ca Sucrose Octasulfate on Cell Migration Epithelial cell migration is an important step in the development and processes of tissue repair, such as embryogenesis and wound healing.
- keratinocytes are "activated" to undertake the process of migration.
- the cells then see their phenotype influenced by interactions with the extracellular matrix on the one hand and by cell-cell interactions on the other hand.
- the keratinocytes of the basal seat of the banks of a wound migrate on the wound and cover it.
- the keratinocyte line used is the HaCaT human keratinocyte line, spontaneously immortalized. This line is frequently cited as a reference model in the literature.
- the protocol used for the study of cell migration is based on the use of a 96-well kit, Oris Cell Migration Assay (Platypus Technologies - TEBU), allowing the miniaturization and quantification of this cellular process.
- the principle of this test is to study cell migration to the well center of the 96-well plate. It involves placing a stopper in wells to create a detection zone of 2 mm in diameter. Then remove the stoppers once the cells have adhered to the surface around them, and thus allow the cells to migrate to the detection zone. Plates without stoppers and with active ingredients are incubated at 37 ° C for 24 hours in DMEM 0% FCS. The amount of cells located in the area where the stopper was then analyzed for cell migration. A cache is used to view and count only cells in this area.

- SOS-Ca can significantly induce the migration of keratinocytes unlike SOS-K and SOS-Na.
- Example 3 Effect of Ca Sucrose Octasulfate on Cell Differentiation
- the epidermis plays a major protective role in providing a chemical and mechanical barrier for the body. It ensures the maintenance of the seal, namely the skin barrier function. Corneocytes, keratinocytes of the stratum corneum, associated with a lipid matrix, largely ensure this function. Nevertheless the deeper layers intervene in the setting up of the actors of this function. The differentiation capacity of the keratinocytes of the epidermis will guarantee the establishment of a barrier of selective functional permeability type.
- Keratinocytes are spatiotemporally regulated, evolving from the deepest layers of the epidermis, the least differentiated basal layer, to the stratum corneum, the ultimate stage of differentiation of keratinocytes into corneocytes. From a protein point of view, the epidermal differentiation is mainly focused on the evolution of structural proteins that are keratins and that contribute to the architectural integrity of the epidermis. Their expression varies according to the degree of maturation of the keratinocytes. Basic keratin 1 and acidic keratin 1 are early markers of keratinocyte differentiation present in the basal layer of the epidermis.
- transglutaminases such as transglutaminase 1 (TGM1) or 3.
- Loricrin is a structural protein containing glutamine and lysine residues for attachment to other proteins in the horny envelope.
- the basic filaggrin molecules (FLG) produced from its precursor profilaggrin (stored in the keratohyaline granules) associate with the cytokeratin filaments, thus allowing their aggregation.
- Filaggrin can then be removed by the enzymes Peptidyl Arginine Deiminase (PAD) and in particular PAD 1 and PAD3.
- PAD Peptidyl Arginine Deiminase
- PAD Peptidyl Arginine Deiminase
- PAD Peptidyl Arginine Deiminase
- keratinocyte lipids are at the origin of the intercorneocyte lipid cement essential for the cutaneous barrier, the formation of which represents the final phase of epidermal terminal differentiation.
- This extracellular lipid matrix provides the main barrier to transcutaneous movements of water and electrolytes.
- a number of enzymes and lipid transporters have their keratinocyte expression increased with differentiation.
- This cement results from a balance between three lipid species, the cholesterol, free fatty acids and ceramides. These lipids are derived from glucosylceramides, sphingomyelin, cholesterol and phospholipids synthesized in the spinous and granular layers.
- the lamellar bodies contain numerous enzymes including lipid hydrolases such as Acid Sphyngomyelinase (aSmase), beta- glucocerebrosidase (GBA) or Plospholipase A2 (sPLA2) as well as acidic and neutral lipases.
- lipid hydrolases such as Acid Sphyngomyelinase (aSmase), beta- glucocerebrosidase (GBA) or Plospholipase A2 (sPLA2) as well as acidic and neutral lipases.
- the barrier function of the skin also includes a defense against microorganisms.
- the epithelium plays an active role in the innate defenses of the host.
- Skin antimicrobial systems are based, among other things, on the presence of certain surface lipids (oleic and palmitoleic acids of sebum and of certain constituent proteins which are increasingly expressed as a function of the differentiation state of keratinocytes (R Ase 7, proteinase Inhibitor 3) Rase 7 and inhibitory proteinase 3 (PI3 or elafin) possess antimicrobial activities, Rnase 7 is a member of the Rnase A family and has broad-spectrum antimicrobial activity. against Gram + or Gram - bacteria.
- acidification of the epidermal surface plays an important role in cutaneous antimicrobial defenses.
- the skin thus acts not only as a physical barrier, but also as a chemical barrier.
- these antimicrobial peptides link the innate and adaptive immune response. They play an important role as mediators of inflammation by having effects on epithelial and inflammatory cells, influencing cell proliferation, scarring, cytokine production, chemokines and chemotaxis.
- Antimicrobial peptides are generally synthesized in the upper layers of the spinous layer and the granular layer, but they are active in the stratum corneum where they are released. Their mode of action is to disrupt the plasma membrane of infectious microbes or to enter the microorganism to interfere with intracellular metabolism.
- the most studied antimicrobial peptides in the skin are ⁇ -defensins and cathelicidines.
- Human ⁇ -defensins are the major class of antimicrobial peptides found in human epithelia and four of them have been identified in the skin, hBD 1-4. Although they belong to the same family, they are regulated by different voices.
- hBD-2 Human ⁇ -defensin 2 (hBD-2 or DEFB4), a 4 kDa peptide binding to heparin, is one of the major cutaneous antimicrobial peptides. Only bacteriostatic against S. aureus, hBD-2 has antimicrobial activity primarily directed against Gram-negative bacteria.
- ⁇ -Defensin 3 (hBD-3), a 5 kDa antimicrobial peptide, has broad-spectrum antimicrobial activity including Staphylococcus aureus.
- Psoriasin belongs to the S100 family of proteins, named after its discovery from psoriasis dander extracts. This 1 1 kDa peptide is in particular produced in cutaneous zones where bacterial colonization is abundant as well as in inflammatory zones. It is mainly directed against Escherichia coll.
- the keratinocyte line used is the line of primary human keratinocytes or NHKs prepared from skin flaps from cosmetic surgery surgical waste (breast reduction).
- test products are incubated with the keratinocytes for 72 hours.
- the cells are then recovered and an analysis of the expression of target genes involved in epidermal differentiation by real-time PCR is performed.
- the products tested are SOS-Ca at 10 ⁇ or 30 ⁇ , SOS-Na at 10 ⁇ or 30 ⁇ , SOS-K at 10 ⁇ or 30 ⁇ , and CaCl 2 at 1.5 mM as a positive control.
- a negative control is carried out in which no product is added to the culture medium.
- S100A7 49 49 133 50 59 205 884 binding protein A7 Table 4: expression of genes involved in cell differentiation in an NHKs keratinocyte line after incubation with SOS-Ca at 10 ⁇ or 30 ⁇ , SOS-Na at 10 ⁇ or 30 ⁇ , SOS-K at 10 ⁇ or 30 ⁇ M or CaCl 2 at 1.5 mM as a percentage of the expression of the different mRNAs relative to the negative control.
- SOS-Ca strongly induced the expression of differentiation markers.
- SOS-K and SOS-Na at 30 ⁇ induced differentiation of keratinocytes in a moderate manner. It can be seen that at 30 ⁇ , SOS-K and SOS-Na induce 8 and 11 targets, respectively, whereas SOS-Ca induces 17. Moreover, the induction of the expression of all genes is stronger by SOS-Ca than with the other two SOS.
- SOS-Ca induced the expression of protein markers of differentiation, proteins involved in lipid synthesis (such as KLK7), involved in desquamation, and induced the expression of antimicrobial peptides like hBD2 (DEFB4). , PB and psoriasin (S100A7).
- SOS-Ca By inducing the expression of Fabaggrin and Padil, SOS-Ca also participates in the synthesis of natural hydration factor.
- SOS-Ca therefore plays a very important role in the differentiation of keratinocytes and activates the physical protein barrier function, lipid and antimicrobial and cutaneous hydration.
- EXAMPLE 4 Effect of Ca Sucrose Octasulfate on the Synthesis of Hyaluronic Acid
- Hyaluronic acid is a component of the extracellular matrix that can be synthesized by keratinocytes and has many functions.
- hyaluronic acid is involved in maintaining cutaneous hydration, proliferation and stimulation of cellular motility during re-epithelialization.
- the amount of hyaluronic acid present at the cutaneous level decreases with age, which is partly responsible for skin aging.
- the keratinocyte line used is the line of primary human keratinocytes or NHKs, prepared from skin flaps from surgical plastic surgery waste (breast reduction).
- test products are incubated with the keratinocytes for 72 hours.
- the culture supernatants are then recovered and an analysis of hyaluronic acid expression is performed by the Duoset Hyaluronan ELISA Kit (ReD Systems) according to the supplier's instructions.
- the products tested are SOS-Ca at 10 ⁇ , SOS-Na at 10 ⁇ , SOS-K at 10 ⁇ , and retinoic acid at 0.1 ⁇ as a positive control.
- a negative control is carried out in which no product is added to the culture medium.
- the values of the amount of hyaluronic acid obtained are shown in FIG. 1 as a percentage of induction relative to the untreated negative control.
- 0.1 ⁇ l retinoic acid a positive control, induced the synthesis of hyaluronic acid by 80%.
- SOS-K and Na do not induce an increase in hyaluronic acid synthesis.
- SOS-Ca therefore plays an important role in the induction of hyaluronic acid synthesis and thus in the hydration and prevention of cutaneous aging.

Exemple 2 : Effet du sucrose octasulfate de Ca sur la migration des cellules La migration des cellules épithéliales est une étape importante du développement et des processus de réparation tissulaire, tels que l'embryogenèse et la cicatrisation. EXAMPLE 2 Effect of Ca Sucrose Octasulfate on Cell Migration Epithelial cell migration is an important step in the development and processes of tissue repair, such as embryogenesis and wound healing.
Lors de la cicatrisation cutanée et dans les affections inflammatoires chroniques dermatologiques, les kératinocytes sont "activés" pour entreprendre le processus de
migration. Les cellules voient alors leur phénotype influencé par les interactions avec la matrice extracellulaire d'une part et par les interactions cellules-cellules, d'autre part. Les kératinocytes de l'assise basale des berges d'une plaie, migrent sur la plaie et la recouvrent. During skin healing and in dermatological chronic inflammatory conditions, keratinocytes are "activated" to undertake the process of migration. The cells then see their phenotype influenced by interactions with the extracellular matrix on the one hand and by cell-cell interactions on the other hand. The keratinocytes of the basal seat of the banks of a wound, migrate on the wound and cover it.
Afin d'évaluer l'impact du sucrose octasulfate de calcium sur la migration cellulaire de lignées de kératinocytes HaCAT, des études ont été réalisées à l'aide du Kit de migration cellulaire Oris Cell Migration Assay (Platypus Technologies). Cette étude a été menée en parallèle avec le sucrose octasulfate de potassium, et le sucrose octasulfate de sodium pour comparaison. To evaluate the impact of calcium sucrose octasulfate on cell migration of HaCAT keratinocyte lineages, studies were performed using the Oris Cell Migration Assay Cell Migration Kit (Platypus Technologies). This study was conducted in parallel with sucrose octasulfate potassium, and sucrose octasulfate sodium for comparison.

- Protocole de migration cellulaire - Cell migration protocol
Le protocole utilisé pour l'étude de la migration cellulaire repose sur l'utilisation d'un kit 96 puits, Oris Cell Migration Assay (Platypus Technologies - TEBU), permettant la miniaturisation et la quantification de ce processus cellulaire. The protocol used for the study of cell migration is based on the use of a 96-well kit, Oris Cell Migration Assay (Platypus Technologies - TEBU), allowing the miniaturization and quantification of this cellular process.
Le principe de ce test consiste à étudier la migration cellulaire vers le centre du puits de la plaque de 96 puits. Il consiste à placer un stoppeur dans des puits, afin de créer une zone de détection de 2 mm de diamètre. Puis de retirer les stoppeurs une fois que les cellules ont bien adhéré à la surface autour de ceux-ci, et ainsi, de permettre aux cellules de migrer vers la zone de détection. Les plaques sans les stoppeurs et avec les actifs sont mises à incuber à 37°C pendant 24 heures dans du DMEM 0% SVF. On analyse ensuite la quantité de cellules situées dans la zone où il y avait le stoppeur, afin d'évaluer la migration des cellules. Un cache permet de visualiser et de comptabiliser uniquement les cellules situées dans cette zone. Pour chaque condition, la moyenne de 6 à 8 puits est réalisée. The principle of this test is to study cell migration to the well center of the 96-well plate. It involves placing a stopper in wells to create a detection zone of 2 mm in diameter. Then remove the stoppers once the cells have adhered to the surface around them, and thus allow the cells to migrate to the detection zone. Plates without stoppers and with active ingredients are incubated at 37 ° C for 24 hours in DMEM 0% FCS. The amount of cells located in the area where the stopper was then analyzed for cell migration. A cache is used to view and count only cells in this area. For each condition, the average of 6 to 8 wells is achieved.

De ce tableau on peut déduire que : From this table we can deduce that:
- L'EGF à 33 ng/ml, contrôle positif de nos expériences, induit la migration (et la prolifération) des kératinocytes de façon importante et significative. - The 33 ng / ml EGF, a positive control of our experiments, induces the migration (and proliferation) of keratinocytes in a significant and significant way.
- A 10 μΜ, le sucrose octasulfate de potassium (SOS-K) et le sucrose octasulfate de sodium (SOS-Na) n'induisent pas la migration des kératinocytes. At 10 μΜ, sucrose octasulfate potassium (SOS-K) and sucrose octasulfate sodium (SOS-Na) do not induce the migration of keratinocytes.
- A 10 μΜ, le sucrose octasulfate de calcium (SOS-Ca) induit de façon statistiquement significative la migration des kératinocytes. At 10 μl, sucrose octasulphate calcium (SOS-Ca) statistically significantly induces the migration of keratinocytes.
Comme on peut le constater, le SOS-Ca permet d'induire signifïcativement la migration des kératinocytes contrairement au SOS-K et SOS-Na. As can be seen, SOS-Ca can significantly induce the migration of keratinocytes unlike SOS-K and SOS-Na.
Exemple 3 : Effet du sucrose octasulfate de Ca sur la différenciation des cellules L'épiderme joue un rôle protecteur majeur en procurant une barrière chimique et mécanique pour le corps. Elle assure le maintien de l'étanchéité, à savoir la fonction barrière cutanée. Les cornéocytes, kératinocytes de la couche cornée, associés à une matrice lipidique, assurent en grande partie cette fonction. Néanmoins les couches plus profondes interviennent dans la mise en place des acteurs de cette fonction. La capacité de différenciation des kératinocytes de l'épiderme va garantir la mise en place d'une barrière de type perméabilité sélective fonctionnelle. Le programme de différenciation
des kératinocytes est régulé de manière spatiotemporelle, évoluant des couches les plus profondes de l'épiderme, couche basale la moins différenciée, vers la couche cornée, stade ultime de différenciation des kératinocytes en cornéocytes. D'un point de vue protéique, la différenciation épidermique est majoritairement axée sur l'évolution de protéines de structure que sont les kératines et qui contribuent à l 'intégrité architecturale de l'épiderme. Leur expression varie en fonction du degré de maturation des kératinocytes. La kératine 1 basique et la kératine 10 acide, sont des marqueurs précoces de la différenciation kératinocytaire, présents dès la couche basale de l'épiderme. L'expression d'autres marqueurs de ce processus biologique, plus tardifs, peut être suivie telle que celle des protéines de l'enveloppe cornée, comme la cornéodesmosine (CDSN), les small prolin rich protein 1 (SPRR1A et SPRR1B), l'involucrine (IVL), ainsi que certaines enzymes majeures à l'origine du pontage des protéines de structure entre elles et avec des lipides kératinocytaires, les transglutaminases, telles que la transglutaminase 1 (TGM1) ou 3. Example 3 Effect of Ca Sucrose Octasulfate on Cell Differentiation The epidermis plays a major protective role in providing a chemical and mechanical barrier for the body. It ensures the maintenance of the seal, namely the skin barrier function. Corneocytes, keratinocytes of the stratum corneum, associated with a lipid matrix, largely ensure this function. Nevertheless the deeper layers intervene in the setting up of the actors of this function. The differentiation capacity of the keratinocytes of the epidermis will guarantee the establishment of a barrier of selective functional permeability type. The differentiation program Keratinocytes are spatiotemporally regulated, evolving from the deepest layers of the epidermis, the least differentiated basal layer, to the stratum corneum, the ultimate stage of differentiation of keratinocytes into corneocytes. From a protein point of view, the epidermal differentiation is mainly focused on the evolution of structural proteins that are keratins and that contribute to the architectural integrity of the epidermis. Their expression varies according to the degree of maturation of the keratinocytes. Basic keratin 1 and acidic keratin 1 are early markers of keratinocyte differentiation present in the basal layer of the epidermis. The expression of other markers of this biological process, later, can be followed such as that of proteins of the horny envelope, such as corneodesmosin (CDSN), small prolin rich protein 1 (SPRR1A and SPRR1B), the involucrine (IVL), as well as certain major enzymes that cause bridging of structural proteins with each other and with keratinocyte lipids, transglutaminases, such as transglutaminase 1 (TGM1) or 3.
La formation de la matrice fibreuse présente dans les cornéocytes est initiée au niveau de la transition entre kératinocytes granuleux et les cornéocytes. La loricrine (LOR) est une protéine de structure contenant des résidus glutamine et lysine permettant la fixation avec d'autres protéines de l'enveloppe cornée. Les molécules basiques de filaggrine (FLG) produites à partir de son précurseur la profilaggrine (stockée dans les granules de kératohyaline) s'associent aux filaments de cytokératine, permettant ainsi leur agrégation. La filaggrine peut être ensuite déiminée par les enzymes Peptidyl Arginine Deiminase (PAD) et notamment PAD 1 et PAD3. La filaggrine déiminée, acide, se détache alors des filaments intermédiaires avant d'être complètement dégradée, engendrant les acides aminés qui constituent le facteur naturel d'hydratation (FNH). Formation of the fibrous matrix present in corneocytes is initiated at the transition between granular keratinocytes and corneocytes. Loricrin (LOR) is a structural protein containing glutamine and lysine residues for attachment to other proteins in the horny envelope. The basic filaggrin molecules (FLG) produced from its precursor profilaggrin (stored in the keratohyaline granules) associate with the cytokeratin filaments, thus allowing their aggregation. Filaggrin can then be removed by the enzymes Peptidyl Arginine Deiminase (PAD) and in particular PAD 1 and PAD3. The degraded filaggrin, acid, then breaks off the intermediate filaments before being completely degraded, generating the amino acids which constitute the natural factor of hydration (FNH).
Parallèlement, la synthèse et le transport de lipides kératinocytaires sont à l'origine du ciment lipidique intercornéocytaire indispensable à la barrière cutanée, dont la formation représente la phase ultime de la différenciation épidermique terminale. Cette matrice lipidique extracellulaire fournit la principale barrière aux mouvements transcutanés d'eau et d'électrolytes. Ainsi un certain nombre d'enzymes et de transporteurs lipidiques voient leur expression kératinocytaire augmentée avec la différenciation. Ce ciment résulte d'un équilibre entre trois espèces lipidiques, le
cholestérol, les acides gras libres et les céramides. Ces lipides dérivent de glucosylcéramides, sphingomyeline, cholestérol et de phospholipides synthétisés dans les couches épineuses et granuleuses. Ils sont transportés via les corps lamellaires, petites vésicules sécrétoires qui fusionnent dans la couche granuleuse et déversent leur contenu à la jonction stratum granulosum/stratum corneum. En plus de ces précurseurs lipidiques, les corps lamellaires contiennent de nombreuses enzymes incluant des hydrolases lipidiques comme la Sphyngomyélinase acide (aSmase), la beta- glucocerebrosidase (GBA) ou les plospholipases A2 (sPLA2) ainsi que des lipases acides et neutres. Co-délivrés avec les précurseurs lipidiques dans les espaces extracellulaires, ces enzymes convertissent respectivement, la sphingomyeline en céramide, la beta-glucocérébroside en céramide et les phospholipides en acides gras libres et glycérol. ELOVL4 (elongation of very long chain fatty acids-4) et la Sphingolipid C4-hydroxylase/delta-4 desaturase (DESG2) interviennent aussi dans la synthèse des céramides et donc sur la fonction barrière de la peau. SULT2B 1 (cholestérol sulfotransferase) permet la sulfonatation du cholestérol dans les couches supérieures de l'épidémie. Finalement FABP5 (fatty acid binding protein) participe au transport et au métabolisme des acides gras. At the same time, the synthesis and transport of keratinocyte lipids are at the origin of the intercorneocyte lipid cement essential for the cutaneous barrier, the formation of which represents the final phase of epidermal terminal differentiation. This extracellular lipid matrix provides the main barrier to transcutaneous movements of water and electrolytes. Thus, a number of enzymes and lipid transporters have their keratinocyte expression increased with differentiation. This cement results from a balance between three lipid species, the cholesterol, free fatty acids and ceramides. These lipids are derived from glucosylceramides, sphingomyelin, cholesterol and phospholipids synthesized in the spinous and granular layers. They are transported via the lamellar bodies, small secretory vesicles that merge into the granular layer and discharge their contents at the junction stratum granulosum / stratum corneum. In addition to these lipid precursors, the lamellar bodies contain numerous enzymes including lipid hydrolases such as Acid Sphyngomyelinase (aSmase), beta- glucocerebrosidase (GBA) or Plospholipase A2 (sPLA2) as well as acidic and neutral lipases. Co-delivered with lipid precursors in extracellular spaces, these enzymes convert sphingomyelin to ceramide, beta-glucocerebroside to ceramide, and phospholipids to free fatty acids and glycerol, respectively. ELOVL4 (elongation of very long chain fatty acids-4) and Sphingolipid C4-hydroxylase / delta-4 desaturase (DESG2) are also involved in the synthesis of ceramides and therefore the barrier function of the skin. SULT2B 1 (cholesterol sulfotransferase) allows sulfonation of cholesterol in the upper layers of the epidemic. Finally FABP5 (fatty acid binding protein) participates in the transport and metabolism of fatty acids.
La fonction barrière de la peau inclut aussi une défense contre les microorganismes. L'épithélium joue un rôle actif dans les défenses innées de l'hôte. Les systèmes antimicrobiens cutanés reposent entre autres sur la présence de certains lipides de surface (acides oléique et palmitoléique du sébum et de certaines protéines constitutives qui sont de plus en plus exprimées en fonction de l'état de différenciation des kératinocytes (R Ase 7, proteinase inhibiteur 3). La R ase 7 et la protéinase inhibiteur 3 (PI3 ou elafïn) possèdent des activités antimicrobiennes. Rnase 7 est un membre de la famille des Rnase A et possède une activité antimicrobienne à large spectre. Elle est ainsi capable d'agir contre des bactéries Gram + ou Gram -. The barrier function of the skin also includes a defense against microorganisms. The epithelium plays an active role in the innate defenses of the host. Skin antimicrobial systems are based, among other things, on the presence of certain surface lipids (oleic and palmitoleic acids of sebum and of certain constituent proteins which are increasingly expressed as a function of the differentiation state of keratinocytes (R Ase 7, proteinase Inhibitor 3) Rase 7 and inhibitory proteinase 3 (PI3 or elafin) possess antimicrobial activities, Rnase 7 is a member of the Rnase A family and has broad-spectrum antimicrobial activity. against Gram + or Gram - bacteria.
De plus, l'acidification de la surface épidermique joue un rôle important dans la défense antimicrobienne cutanée. La peau agit ainsi non seulement comme une barrière physique, mais aussi comme une barrière chimique. Il existe également une composante adaptative de l'immunité innée reposant sur la sécrétion inductible de peptides antimicrobiens. Ils possèdent des activités antimicrobiennes directes contre des bactéries variées, des virus et des champignons avec la capacité d'inhiber leur
croissance. En plus, de par leur action chimiotactique, ces peptides antimicrobiens font le lien entre réponse immunitaire innée et adaptative. Ils jouent un rôle important comme médiateurs de l'inflammation en ayant des effets sur les cellules épithéliales et inflammatoires, en influençant la prolifération cellulaire, la cicatrisation, la production de cytokines, chimiokines et la chimiotaxie. Les peptides antimicrobiens sont généralement synthétisés dans les couches supérieures de la couche épineuse et la couche granuleuse, mais ils sont actifs dans la couche cornée où ils sont libérés. Leur mode d'action consiste à rompre la membrane plasmique des microbes infectieux ou à pénétrer dans le microorganisme afin d'interférer avec le métabolisme intracellulaire. Les peptides antimicrobiens les plus étudiés dans la peau sont les β-défensines et les cathélicidines. In addition, acidification of the epidermal surface plays an important role in cutaneous antimicrobial defenses. The skin thus acts not only as a physical barrier, but also as a chemical barrier. There is also an adaptive component of innate immunity based on the inducible secretion of antimicrobial peptides. They possess direct antimicrobial activities against various bacteria, viruses and fungi with the ability to inhibit their growth. In addition, by their chemotactic action, these antimicrobial peptides link the innate and adaptive immune response. They play an important role as mediators of inflammation by having effects on epithelial and inflammatory cells, influencing cell proliferation, scarring, cytokine production, chemokines and chemotaxis. Antimicrobial peptides are generally synthesized in the upper layers of the spinous layer and the granular layer, but they are active in the stratum corneum where they are released. Their mode of action is to disrupt the plasma membrane of infectious microbes or to enter the microorganism to interfere with intracellular metabolism. The most studied antimicrobial peptides in the skin are β-defensins and cathelicidines.
Les β-défensines humaines constituent la classe maj eure des peptides antimicrobiens retrouvés dans les épithéliums humains et quatre d'entrés elles ont été identifiées dans la peau, hBD 1-4. Bien qu'elles appartiennent à la même famille, elles sont régulées par des voix différentes. Human β-defensins are the major class of antimicrobial peptides found in human epithelia and four of them have been identified in the skin, hBD 1-4. Although they belong to the same family, they are regulated by different voices.
La β-défensine 2 humaine (hBD-2 ou DEFB4), un peptide de 4 kDa se liant à l'héparine est l'un des principaux peptides antimicrobiens cutanés. Seulement bactério statique face à S. aureus, hBD-2 possède une activité antimicrobienne essentiellement dirigée contre les bactéries à Gram négative. Human β-defensin 2 (hBD-2 or DEFB4), a 4 kDa peptide binding to heparin, is one of the major cutaneous antimicrobial peptides. Only bacteriostatic against S. aureus, hBD-2 has antimicrobial activity primarily directed against Gram-negative bacteria.
La β-défensine 3 (hBD-3), un peptide antimicrobien de 5 kDa présente une activité antimicrobienne à large spectre incluant Staphylococcus aureus. Β-Defensin 3 (hBD-3), a 5 kDa antimicrobial peptide, has broad-spectrum antimicrobial activity including Staphylococcus aureus.
La psoriasine (S100A7), appartient à la famille des protéines S 100, tient son nom du fait qu'elle fut découverte à partir d'extraits de squames de psoriasis. Ce peptide de 1 1 kDa est notamment produit dans les zones cutanées où la colonisation bactérienne est abondante ainsi que dans les zones inflammatoires. Elle est principalement dirigée contre Escherichia coll. Psoriasin (S100A7) belongs to the S100 family of proteins, named after its discovery from psoriasis dander extracts. This 1 1 kDa peptide is in particular produced in cutaneous zones where bacterial colonization is abundant as well as in inflammatory zones. It is mainly directed against Escherichia coll.

S100A7 49 49 133 50 59 205 884 binding protein A7 Table 4: expression of genes involved in cell differentiation in an NHKs keratinocyte line after incubation with SOS-Ca at 10 μΜ or 30 μΜ, SOS-Na at 10 μΜ or 30 μΜ, SOS-K at 10 μΜ or 30 μM or CaCl 2 at 1.5 mM as a percentage of the expression of the different mRNAs relative to the negative control.
Comme on pouvait s'y attendre le calcium à 1.5 mM, contrôle positif des expériences, a bien induit l'expression des gènes impliqués dans la différenciation des kératinocytes ainsi que dans la synthèse de peptides antimicrobiens. As expected, calcium at 1.5 mM, a positive control of the experiments, well induced the expression of the genes involved in the differentiation of keratinocytes as well as in the synthesis of antimicrobial peptides.
Le SOS-Ca a induit fortement l'expression des marqueurs de différentiation. Au contraire les SOS-K et SOS-Na à 30 μΜ ont induit la différenciation des kératinocytes de façon modérée. On peut constater que, à 30 μΜ, le SOS-K et le SOS-Na ont induit respectivement 8 et 11 cibles alors que le SOS-Ca en a induit 17. De plus, l'induction de l'expression de l'ensemble des gènes est plus forte par le SOS-Ca qu'avec les deux autres SOS. SOS-Ca strongly induced the expression of differentiation markers. In contrast, SOS-K and SOS-Na at 30 μΜ induced differentiation of keratinocytes in a moderate manner. It can be seen that at 30 μΜ, SOS-K and SOS-Na induce 8 and 11 targets, respectively, whereas SOS-Ca induces 17. Moreover, the induction of the expression of all genes is stronger by SOS-Ca than with the other two SOS.
Ainsi le SOS-Ca a induit l'expression des marqueurs protéiques de la différenciation, de protéines impliquées dans la synthèse des lipides (tel que KLK7), impliquées dans la desquamation, et a induit l'expression de peptides antimicrobiens comme hBD2 (DEFB4), PB et la psoriasine (S100A7). Thus, SOS-Ca induced the expression of protein markers of differentiation, proteins involved in lipid synthesis (such as KLK7), involved in desquamation, and induced the expression of antimicrobial peptides like hBD2 (DEFB4). , PB and psoriasin (S100A7).
En induisant l'expression de la fïlaggrine et de Padil, le SOS-Ca participe aussi à la synthèse de facteur naturel d'hydratation. By inducing the expression of Fabaggrin and Padil, SOS-Ca also participates in the synthesis of natural hydration factor.
Par ailleurs, il est à noter que l'effet du SOS-Ca ne peut pas être imputé à la seule contribution de la partie Ca (équivalente à 120 μΜ). Cette concentration en calcium, 10 fois inférieure à celle du contrôle positif, n'est pas suffisante pour induire les marqueurs de la différenciation des cellules dans les conditions expérimentales. Par ailleurs, le tableau montre que le SOS-K et le SOS-Na n'induisent pas de façon dose dépendante et significative tous les marqueurs de cette différenciation. En conséquence, cette différenciation est donc bien induite, de façon inattendue, par la synergie du SOS et du Ca présents dans le SOS-Ca. De plus, les résultats montrent que les propriétés du SOS- Ca, notamment sur l'expression des marqueurs de la différenciation des kératinocytes, sont supérieures à celles obtenues avec le contrôle positif Ca à 1.5 mM.
Le SOS-Ca joue donc un rôle très important dans la différenciation des kératinocytes et active la fonction barrière physique protéique, lipidique et antimicrobienne ainsi que l'hydratation cutanée. Exemple 4 : Effet du sucrose octasulfate de Ca sur la synthèse d' acide hyaluronique Moreover, it should be noted that the effect of SOS-Ca can not be attributed to the contribution of the Ca part alone (equivalent to 120 μΜ). This calcium concentration, 10 times lower than that of the positive control, is not sufficient to induce markers of cell differentiation under experimental conditions. Moreover, the table shows that SOS-K and SOS-Na do not induce in a dose-dependent and significant manner all the markers of this differentiation. As a consequence, this differentiation is thus unexpectedly induced by the synergy of SOS and Ca present in SOS-Ca. In addition, the results show that the properties of SOS-Ca, especially on the expression of keratinocyte differentiation markers, are higher than those obtained with the 1.5 mM Ca positive control. SOS-Ca therefore plays a very important role in the differentiation of keratinocytes and activates the physical protein barrier function, lipid and antimicrobial and cutaneous hydration. EXAMPLE 4 Effect of Ca Sucrose Octasulfate on the Synthesis of Hyaluronic Acid
L'acide hyaluronique est un composant de la matrice extracellulaire pouvant être synthétisé par les kératinocytes et ayant de nombreuses fonctions. En particulier, l'acide hyaluronique est impliqué dans le maintient de l'hydratation cutanée, dans la prolifération et la stimulation de la motilité cellulaire, pendant la ré-épithélialisation. La quantité d'acide hyaluronique présente au niveau cutané diminue avec l'âge ce qui est en partie responsable du vieillissement cutané. Hyaluronic acid is a component of the extracellular matrix that can be synthesized by keratinocytes and has many functions. In particular, hyaluronic acid is involved in maintaining cutaneous hydration, proliferation and stimulation of cellular motility during re-epithelialization. The amount of hyaluronic acid present at the cutaneous level decreases with age, which is partly responsible for skin aging.
L'effet du sucrose octasulfate de calcium sur la synthèse d'acide hyaluronique a été testé. The effect of calcium sucrose octasulfate on hyaluronic acid synthesis was tested.
-Matériel biologique -Organic material
La lignée de kératinocytes utilisée est la lignée est la lignée de kératinocytes humains primaires ou NHKs, préparée à partir de lambeaux cutanés issus de déchets opératoires de chirurgie esthétique (diminution mammaire). The keratinocyte line used is the line of primary human keratinocytes or NHKs, prepared from skin flaps from surgical plastic surgery waste (breast reduction).
-Protocole expérimental -Experimental protocol
Les produits à tester sont incubés avec les kératinocytes pendant 72 heures. Les surnageants de culture sont ensuite récupérés et une analyse de l'expression de l'acide hyaluronique est réalisée par le kit ELISA Duoset Hyaluronan (ReD Systems) selon les instructions du fournisseur. Les produits testés sont le SOS-Ca à 10 μΜ, le SOS-Na à 10 μΜ, le SOS-K à 10 μΜ, et l'acide retinoïque à 0,1 μΜ en tant que témoin positif. Un témoin négatif est réalisé dans lequel aucun produit n'est ajouté au milieu de culture. The test products are incubated with the keratinocytes for 72 hours. The culture supernatants are then recovered and an analysis of hyaluronic acid expression is performed by the Duoset Hyaluronan ELISA Kit (ReD Systems) according to the supplier's instructions. The products tested are SOS-Ca at 10 μΜ, SOS-Na at 10 μΜ, SOS-K at 10 μΜ, and retinoic acid at 0.1 μΜ as a positive control. A negative control is carried out in which no product is added to the culture medium.
Résultats Results
Les valeurs de la quantité d'acide hyaluronique obtenues sont représentées sur la Figure 1 en pourcentage d'induction par rapport au témoin négatif non traité. The values of the amount of hyaluronic acid obtained are shown in FIG. 1 as a percentage of induction relative to the untreated negative control.
Comme on pouvait s'y attendre, l'acide rétinoïque à 0.1 μΜ, témoin positif, a induit la synthèse d'acide hyaluronique de 80%.
Les SOS-K et Na n'induisent pas une augmentation de la synthèse d'acide hyaluronique. As expected, 0.1 μl retinoic acid, a positive control, induced the synthesis of hyaluronic acid by 80%. SOS-K and Na do not induce an increase in hyaluronic acid synthesis.
En revanche le SOS-Ca à 10 μΜ a bien induit la synthèse d'acide hyaluronique de 38%. Cette induction est statistiquement significative par rapport au témoin non traité. On the other hand, SOS-Ca at 10 μΜ did induce the synthesis of hyaluronic acid by 38%. This induction is statistically significant compared to the untreated control.
Le SOS-Ca joue donc un rôle important dans l'induction de la synthèse de l'acide hyaluronique et donc dans l'hydratation et la prévention du vieillissement cutané.
SOS-Ca therefore plays an important role in the induction of hyaluronic acid synthesis and thus in the hydration and prevention of cutaneous aging.
