Psoriasis Targeted Therapy: Characterization of Interleukin 17A Expression in Subtypes of Psoriasis.

Abstract

The results of our study suggests the significant role of the cytokine IL-17A in the development of palmoplantar and pustular psoriasis. However, scalp and guttate subtypes showed variable expression from negative to strongly positive, which demonstrates a case by case basis expression of IL-17A. Therefore, exploring the IHC characterization of subtypes of psoriasis will help dermatologists better understand the pathogenesis of each subtype and help clinicians optimize treatments.
