WebMar 5, 2024 · ADCC occurs when the Fab region of an IgG antibody binds to a large pathogen; Fc receptors on effector cells (e.g., NK cells) then bind to the Fc region of the antibody, bringing them into close proximity with the target pathogen. The effector cell then secretes powerful cytotoxins (e.g., perforin and granzymes) that kill the pathogen. WebApr 7, 2024 · TNX contains the rupluzimab Fab and an IgG4 Fc region engineered to reduce binding to FcγRIIa and associated risks of thrombosis.
