The immunological and genetic aspects in psoriasis
Psoriasis is a chronic and immune-mediated inflammatory skin disorder associated with complex genetic susceptibility. Studies focused on the immunological mechanism have revealed innate and adaptive immune activation in psoriatic lesions, including large numbers of immune cells activated to produce many cytokines, chemokines, and other inflammatory molecules. Knowledge on the genetic basis of psoriasis highlights genetic susceptibility factors that play a crucial role in regulation of immunity, epidermal proliferation, and skin barrier formation. Genetic susceptibility factors affecting both the immune system and epidermis could predispose to disease. Herein, we review the current knowledge on the role of genetic and immunological factors in the development of psoriasis.
