چکیده

Psoriasis is a chronic genetically determined, erythemato-squamous disease associated with many comorbidities. Evidence from clinical studies and experimental models support the concept that psoriasis is a T cell-mediated inflammatory skin disease and T helper (Th) cells - Th1, Th17 and Th22 - play an important role in the pathogenesis. Th1 cytokines IFNγ, IL-2, as well as Th17 cytokines IL-17A, IL-17F, IL-22, IL-26, and TNFα (Th1 and Th17 cytokine) are increased in serum and lesional skin. IL-22 produced by Th17 and new subset of T helper cells, Th22, is also increased within psoriatic lesions and in the serum. Other recently recognized cytokines of significant importance in psoriasis are IL-23, IL-20 and IL-15. The IL-23/Th17 pathway plays a dominant role in psoriasis pathogenesis. Currently due to enormous methodological progress, more and more clinical and histopathological psoriatic features could be explained by particular cytokine imbalance, which still is one of the most fascinating dermatological research fields stimulating new and new generations of researchers.

Increased Serum Levels of TNF-Α and IL-6 are not Related to HLA-Cw6 in Psoriasis Patients Correlation of Cytokine with HLA Cw6

Psoriasis is a T cell mediated inflammatory skin disease. Complex network of cytokine induces and maintain the psoriatic lesion. Study was performed to evaluate the correlation between the level of TNFα and IL-6, in the psoriasis patients with HLA-Cw6. Cytokine levels were assayed by sandwich ELISA and HLA-Cw6 typing was done by microcytoxicity method. Serum TNF-α and IL-6 were significantly (p...

New insights in the immunologic basis of psoriasis.

Psoriasis vulgaris is a multifactorial heritable disease characterized by severe inflammation resulting in poorly differentiated, hyperproliferative keratinocytes. Recent advances in genetic analyses have implicated components regulating the interleukin (IL)-23 and nuclear factor-kappaB pathways as risk factors for psoriasis. These inflammatory pathways exhibit increased activity in skin lesion...

Tumor necrosis factor-alpha and the cytokine network in psoriasis.

New molecular methods of research have greatly expanded the knowledge about the role of cytokines in several diseases, including psoriasis. The work orchestrated by these peptides is essential for the communication between resident inflammatory cells (keratinocytes and endothelial cells) and infiltrating cells (neutrophils, lymphocytes, Langerhans cells). This is a complex network due to redund...

Cytokine network in psoriasis. Cross-talk between keratinocytes and cells of the skin immune system

Psoriasis is a common autoimmune skin disease characterized by T cell-mediated hyperproliferation of keratinocytes. The cutaneous and systemic overexpression of a variety of proinflammatory cytokines such as TNF-α, IL-1, IL-6, IL-8, IL-15, IL-18, IL-19, IL-20, IL-22, IL-23 and IFN-gamma, has been demonstrated. The cellular composition of the inflammatory infiltrate within the psoriatic plaques,...
