Skin immune system

Abstract

Primarna uloga kože jest mehanička zapreka, te je kao takva ključan organ kod urođene, nespecifične imunosti. No, ukoliko patogen ili neki drugi okolišni čimbenik prebrodi tu zapreku, u koži se aktivira niz različitih mehanizama koji mogu pokrenuti specifičan imunološki odgovor. U koži može doći do staničnog imunološkog odgovora, čiji su posrednici stanice imunološkog sustava, ali i neke druge stanice karakteristične za kožu, te može doći i do humoralnog imunološkog odgovora, posredovanog topljivim tvarima poput protutijela, citokina, kemokina, antimikrobnih peptida i ostalih. Kožne bolesti poput atopičkog dermatitisa, psorijaze, akni ili tumora zahvaćaju velik postotak ljudske populacije, te nastaju kako zbog genetičkih, tako i zbog imunoloških poremećaja.Primary function of the skin is a mechanical barrier, which makes it a key organ of native, unspecific immune system. But, if some patogen or any other enviromental factor enters through that barrier, a series of different mechanisms in skin are activated and therefore can be induced a specific immunological response. Immunological responses in skin can be cellular, in which mediators are immunological or other skin cells, or they can be humoral, in which mediators are soluble substances like antibodies, cytokines, chemokines, antimicrobial peptides, complements and other. Skin diseases like atopic dermatitis, psoriasis, acne or tumors affect high percentage of human population, and their origin could be a concequence after some genetical or immunological disorder
