Atopic dermatitis is a skin condition that causes inflammation and discomfort. Scientists have found that a pathway called JAK-STAT, involving specific proteins, plays a role in the disease. This pathway is linked to various cytokines that contribute to the symptoms of atopic dermatitis. While the exact details of how JAK-STAT affects the condition are still being studied, it is clear that this pathway is involved in the immune response that leads to skin problems in atopic dermatitis.
