Psoriasis is a skin condition that occurs when cells in the outer layer of skin reproduce faster than normal and pile up on the surface of the skin. This product scaling, itching and irritation. Psoriasis is not contagious.
There have been major advances in understanding what causes psoriasis. Recently, a team from the University of Michigan looked for the gene - called PSORS1 - for more than 2,700 people from 678 families where at least one family member had psoriasis. According to the researchers, is the first genetic determinant of psoriasis PSORS1 to be definitively identified in a clinical trial on a large scale. The discovery could help develop more effective treatments for inflammatory disease of the skin disfiguring.
Some other research has shown that psoriasis may be an immune system disorder. In a normal immune system of a type of white blood cell called T lymphocyte is produced, which normally helps protect the body against infection and disease. The scientists concluded that the best of the abnormal cells of the immune system T in the skin produce too. These T cells trigger excessive inflammation and excessive reproduction of skin cells in people suffering from psoriasis.
Doctors usually diagnose psoriasis after a careful examination of the skin. However, the diagnosis can be difficult because psoriasis often looks like other skin diseases. A pathologist can help in the diagnosis by examining a small skin sample under a microscope.
For those who have weakened immune systems, symptoms of psoriasis can be very serious.
