Arachidonic acid in psoriasis. Pathogenic role and pharmacological regulation

AA and its derivatives are a family of potent mediators and regulators of inflammation. There are several pieces of evidence to suggest a pathophysiologic role of certain AA derivatives in psoriasis. The complexity of the pathways in the generation of LTs and other LO products suggests that carefully designed systems will be needed to establish the exact role of these compounds in the pathogenesis of diseases such as psoriasis, and to test the effects of pharmacological inhibitors.
