Know the causes

What causes psoriasis?

The exact cause of psoriasis is unknown but is most likely caused by an autoimmune response. More specifically, one key cell is a type of white blood cell called a T lymphocyte or T cell. Normally, T cells travel throughout the body to detect and fight off foreign substances, such as viruses or bacteria. If you have psoriasis, however, the T cells attack healthy skin cells by mistake, as if to heal a wound or to fight an infection. Psoriasis is not infectious or cancerous.
