What causes psoriasis?
Psoriasis is an autoimmune condition, which means that it is caused by certain immune (T cells) being triggered and becoming over-active.
The T cells act as if they are fighting an infection or healing a wound, which leads them to producing inflammatory chemicals, which causes a rapid growth of skin cells causing psoriatic plaques to form. At present it is not known what triggers the T cells to act in this way.
Some people may have a family history of the condition, while others will have none. Psoriasis flare-ups can triggered by a number of reasons, such as hormonal changes, stress or anxiety, injury to the skin or certain infections and medications.
Researchers are continuing the conduct studies to try and find what causes psoriasis and an all important cure.
