Role of innate immune receptors in the psoriasis development
Psoriasis is an immune-mediated autoimmune inflammatory skin disease with a prevalence of 2 to 3% worldwide. In the psoriasis development and pathogenesis an important role is played by disorders in the immune system. Disruption of the innate and adaptive immune response mechanisms with the involvement of keratinocytes leads to the initiation and maintenance of inflammation.
Immune reactions are activated in the skin, in which various cells participate (macrophages, dendritic cells, mast cells, innate immune lymphoid cells, melanocytes, keratinocytes, Langerhans cells and γδT cells; T and B cells; epithelial endothelial and stromal cells of the skin), each of which expresses pattern recognition receptors that respond to pathogens and cell damage itself. Many of these receptors, in particular toll-like receptors and NOD-like receptors play an important role in the pathogenesis of psoriasis. The associated innate receptors signaling cascades that activate in the skin cells may become potential targets for the treatment of this disease.
To date, there are several approved drugs for biological therapy of psoriasis.
The study of the role of the innate immune cells receptors in inflammatory skin pathologies requires further exploration and new developments.
