Immune Mediated About Psoriasis

Researchers now believe that psoriasis is an immune-mediated condition. This means the condition is caused by faulty signals in the body’s immune system. It is believed that psoriasis develops when the immune system tells the body to over-react and accelerate the growth of skin cells. Normally, skin cells mature and are shed from the skin’s surface every 28 to 30 days. When psoriasis develops, the skin cells mature in 3 to 6 days and move to the skin surface. Instead of being shed, the skin cells pile up, causing the visible lesions.
