Background:CD161 is also known as NKR-P1A, CLEC5B and KLRB1which plays an inhibitory role on natural killer (NK) cells cytotoxicity.
Activation results in specific acid sphingomyelinase/SMPD1 stimulation with subsequent marked elevation of intracellular ceramide.
Activation also leads to AKT1/PKB and RPS6KA1/RSK1 kinases stimulation as well as markedly enhanced T-cell proliferation induced by anti-CD3.
Acts as a lectin that binds to the terminal carbohydrate Gal-alpha Gal epitope as well as to the N-acetyllactosamine epitope.
Binds also to CLEC2D/LLT1 as a ligand and inhibits NK cell-mediated cytotoxicity as well as interferon-gamma secretion in target cells.
New research shows that genetic inactivation of KLRB1 or antibody-mediated CD161 blockade enhances T cell-mediated killing of glioma cells in vitro and their anti-tumor function in vivo.
KLRB1 and its associated transcriptional program are also expressed by substantial T cell populations in other human cancers.
