The importance of specific autoimmune disorders in the pathogenesis of psoriasis and the prospects of immunobiological therapy of dermatosis

Objective — to analyze the features of specific autoimmune disorders in patients with psoriasis, determine their importance in the pathogenesis of this dermatosis, and assess the prospects of immunobiological therapy for dermatosis. 
Materials and methods. Based on an in-depth analysis of the results of modern special studies, the leading role of specific autoantigens and autoantibodies in the body of patients with this dermatosis has been confirmed in the pathogenesis of psoriasis. 
Results and discussion. The article analyzes the importance of specific autoantigens, including keratin-17, LL-37, ADAMTSL5, and lipid antigens generated by PLA2G4D, which are essential in the pathogenesis of psoriasis. Emphasis is placed on the potential importance of immunobiological therapy, which significantly decrease levels of autoantigens LL-37 and ADAMTSL5 in areas of skin affected by psoriatic rash. The prospects of therapeutic approaches to the inhibition of cytokines derived from T cells and innate cells, such as IL-17, as well as to the inhibition of PLA2G4D or CD1a are also considered. Further study of specific autoimmune disorders in patients with psoriasis is important to improve therapeutic approaches to the treatment of psoriasis. 
Conclusions. Autoimmune disorders, combined with genetic and a number of other factors, are one of the important of the development of psoriasis. Analysis of the results of current special studies has promising therapeutic value because, in addition to supporting approaches to inhibiting cytokines derived from T cells and dendritic cells, they support the development of approaches to inhibiting autoantigens directly.
