Yes, psoriasis is considered an autoimmune disease. In autoimmune conditions, the immune system mistakenly attacks the body’s own cells, leading to inflammation and other symptoms.
In the case of psoriasis, the immune system targets the skin cells, causing an overproduction of new skin cells. This rapid turnover of skin cells results in the formation of thick, red, and scaly patches on the skin.
The exact cause of psoriasis is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Specific immune system issues that contribute to psoriasis include:
T cells (T lymphocytes): These are a type of white blood cell that plays a central role in the immune response. In psoriasis, T cells are activated and mistakenly attack healthy skin cells.
