T cell-mediated Skin Diseases

T cell-mediated skin diseases occur when the body's immune system, specifically T cells, mistakenly targets healthy skin tissues, causing inflammation and damage. These conditions include psoriasis and eczema, where the immune response leads to symptoms like redness, itching, scaling, and swelling. T cells are normally important for defending against infections, but in these diseases, they become overactive or misdirected. This immune imbalance results in chronic skin inflammation, often requiring treatments that help control the immune response and reduce symptoms.
