In the human body, it is the duty of the immune system to destroy foreign substances and proteins entering the body. In psoriasis, immune system cells perceive the deepest layer of the deep as foreign matter and cause damage. The reason why the immune system is mistakenly perceived as a foreign substance by the body of its own body is the presence of antibodies that bind to these antigens and accumulate at the bottom of substances that carry the antigenic properties of vaccines or past diseases. Antigenic residues are formed by passage of harmful proteins into the bloodstream of the endothelium, which increases the permeability of the intestinal wall (which can be thought of as enlargement of the suture holes). The resulting complex of antigen-antibody conjugate shows as a false target for the immune system and causes deep damage.
The upper layer of the deeply damaged layer begins to regenerate rapidly. Normally renewed in 1 month, the upper layer is renewed in psoriasis 3-4 days, resulting in swelling.
Common therapies are the treatment of superficial creams, light treatments, or immunosuppression. However, these treatments are temporary and partially beneficial because they are not directed at the treatment.
Ideal treatment; Deeply choosing the wrong target should determine the causes and remove it from the scene. Each person should have a special treatment program.
There is a similar mechanism in the eczema. Wound-like lesions are seen instead of derailing.
Different foreign matter effects can also be caused by local contact.
