NCIt definition : A humanized, afucosylated monoclonal antibody directed against killer cell lectin-like
receptor G1 (KLRG1), with potential immunomodulatory activity. Upon administration,
anti-KLRG1 monoclonal antibody ABC008 targets and binds to KLRG1 expressed on highly
differentiated effector CD8 cytotoxic T-cells, and selectively depletes these highly
differentiated cytotoxic T-cells while sparing other immune cells. This prevents the
killing of cells by these highly differentiated cytotoxic T-cells in certain autoimmune
diseases, such as the destruction of muscle tissue in inclusion body myositis, and
the destruction of neutrophils and red blood cell precursors in T-cell large granular
lymphocytic leukemia (T-LGLL).;
