Researchers have been unable to identify a singular cause for psoriasis, but studies suggest psoriasis is an autoimmune disease—it begins in the immune system, the result of your immune system’s overreaction to stimuli.
In a properly-functioning immune system, T-cells, a kind of white blood cell, protect the body against infection and disease by identifying and destroying foreign material. With psoriasis, T-cells overreact, mistaking healthy skin cells for dangerous ones, and set off a chain of unneeded immune system responses.
Certain factors may trigger psoriasis in a person who has never had symptoms before. And for those who have psoriasis, these same factors can trigger another bout with the disease.
