Fc-enhanced anti-CCR6 antibody elicits robust therapeutic effects across multiple autoimmune diseases.

ABSTRACT: Activation of the chemokine receptor CCR6 orchestrates the trafficking of IL-17-producing pathogenic immune cells to the sites of inflammation, thus contributing to the development of numerous inflammatory and autoimmune diseases. As such, CCR6 has emerged as a promising therapeutic target for treating Th17-mediated inflammatory disorders. In this study, we employed a targeted strategy, which we termed 'immunological surgery', using an Fc-engineered anti-human CCR6 monoclonal antibody (αhCCR6 DLE-mut mAb) designed to engage effector mechanisms against CCR6⁺ immune cells and deplete them. We evaluated the therapeutic efficacy of this approach in preclinical mouse models of representative autoimmune conditions, including scleroderma, psoriasis, and rheumatoid arthritis. Selective
