Description
Technical field
The invention belongs to the technical fields of lactic acid bacteria, are related to the application that lactic acid bacteria inhibits bacterium, and in particular to lactic acid bacteria exists
Inhibit application in propionibacterium acnes and with its manufactured skin care item.
Background technique
Acne is a kind of chronic inflammatory skin of pilosebaceous follicle, and disease incidence 70%-87% is apt to occur in puberty,
Clinical manifestation is mainly with facial area and chest and back blackhead, Whiteheads, based on inflammatory papules, warts.Under androgenic effect
Sebaceous glands Rapid development and lipid largely secrete be acne occur pathophysiological basis；Pilosebaceous duct dyskeratosis is
Another key factor and main pathological phenomenon occur for acne, and epithelial cell angling makes pilosebaceous duct blocking, sebum discharge
Obstacle, ultimately forms visible micro mist thorn and clinical macroscopic acne under microscope, and micro mist thorn and acne are formed as
Propionibacterium acnes proliferation with anaerobic growth characteristic creates good local environment.Acne occur exactly with acne propionic acid
Bacillus is closely related, it is now recognized that propionibacterium acnes may be taken part in by the innate immunity, acquired immunity and directly induction
The occurrence and development of acne inflammation.Acne Earlier period of inflammation may be induction caused by the innate immune reaction that Toll-like is mediated by (TLR)
Proinflammatory inflammation factor especially IL-1 α release；As disease develops, the acquired immune response is exaggerated inflammatory process, further leads
Cause inflammatory factor release and neutrophil accumulation；Propionibacterium acnes also can produce polypeptides matter, directly induces or aggravates
Inflammation.In end-stage disease, follicular wall is broken, and the substances such as lipid, hair in hair follicle enter corium, and it is anti-that inflammation has been further aggravated
It answers.
Part patients with acne skin barrier is impaired, and Long-term Oral or external application anti-acne drug such as Tretinoin, often aggravates
The destruction of skin barrier, leads to skin sensitivity.Therefore, how effectively to inhibit propionibacterium acnes, while protecting original skin
Barrier is the emphasis that we research and develop at present.
