Mechanism Of Action and Pharmacodynamic Effects Click here for help
KLRC1 forms functional heterodimers with CD94 (KLRD1) to form a human leukocyte antigen E (HLA-E) recognition complex on a subset of natural killer (NK) cells and cytotoxic T lymphocytes. KLRC1/CD94/HLA-E binding suppresses immune vigilance, and overexpression of HLA-E is used by cancer cells to evade immune recognition and destruction [2,5-6,9]. Anti-KLRC1 monoclonals such as IPH2201 block KLRC1/CD94 activation, re-establishing NK and T cell-driven destruction of cancer cells, even in the presence of HLA-E [3].
