Causes of Psoriasis

The cause of psoriasis is not fully understood, but is thought to relate to a person's immune system is weak especially those with a genetic susceptibility. More specifically, there is one key cells are the type of white blood cells called T lymphocytes or T cells Normally, T cells travel throughout the body to detect and fight foreign substances, such as viruses or bacteria. But, if you have psoriasis, T cells attack the skin cells healthy by mistake, when he meant to heal wounds or to fight infection.

Overactive T cells trigger other immune responses. Its effects include dilation of blood vessels in the skin around the plaque and increase in other white blood cells to go into the outer layer of the skin. These changes result in increased production of skin cells. This causes the displacement cycle of new skin cells to the outermost layer of skin too quickly, which occur within days, not weeks. Dead skin and white blood cells can not flake off fast enough, so consequently the skin becomes thick and flaky on the skin surface. This usually does not stop unless treatment.

 
What causes abnormal T cells in people with psoriasis is not entirely clear, although researchers think genetic and environmental factors have a significant role.
