title: A comprehensive review of biomarkers in psoriasis.
abstract: Psoriasis is a common, chronic skin disorder, the pathogenesis of which is incompletely understood. Results from various clinical and experimental studies indicate that psoriasis is a complex, multifactorial disease with a genetic predisposition. Factors such as climate, physical trauma, drug, stress and infections (Streptococcus, human immunodeficiency virus) are known to trigger psoriasis. The success of treatment of psoriasis with T-cell depletion and antitumour necrosis factor (TNF)-alpha treatment is explained by the involvement of T cells and TNF- alpha in the pathogenesis of psoriasis. The biochemical basis for the pathogenesis of psoriasis can be attributed to both overexpression and underexpression of certain proteins in psoriatic lesions. The anomalies in protein expression can be classified as abnormal keratinocyte differentiation, keratinocyte hyperproliferation and inflammation. Oxidative stress (OS) and increased free-radical generation have been linked to skin inflammation in psoriasis. The review presents evidence for various markers of psoriasis that can be targeted for effective treatment, including biomarkers of inflammation, keratinocyte hyperproliferation and abnormal differentiation, and stress.
