Used in the treatment of inflammatory skin conditions such as psoriasis by targeting and neutralizing interleukin-20 (IL-20), a cytokine involved in skin cell overgrowth and inflammation. It helps reduce plaque formation, redness, and scaling by modulating the immune response in affected tissues. Investigated for potential use in other autoimmune disorders where IL-20 plays a role, including rheumatoid arthritis and lupus-related skin manifestations.
