Psoriasis 

psoriasis treatment,Psoriasis is an immune mediated , chronic, non contagious skin disorder characterized by scaling and inflammation due to increased cell growing, that can develop on virtually any part of the body, even the nails and scalp.

Normally, skin cells grow gradually and flake off about every 4 weeks, replacing with new cells.  In psoriasis, new skin cells move rapidly to the surface of the skin, within a week.

Pathogenesis  Psoriasis treatment in hyderabad india

The pathogenetic pathway  involves various immunocytes and immune molecules. Activated Tcells will trigger a chain of cellular and molecular reactions leading to the formation of psoriatic lesions. Although the roles of T cells in psoriasis have been confirmed, the exact mechanisms of psoriasis and the origin of abnormal T cells are still unclear. A variety of other immune abnormalities such as B cells, monocytes, neutrophils and erythrocytes are also seen in action.

Typical characteristics of psoriasis are red, dry, elevated plaques of skin. Psoriasis is not contagious
