The present disclosure provides
monoclonal antibodies that recognize human
Nectin-2 (
Nectin-2, Poliovirus
Receptor-Related
Protein-2, Poliovirus
Receptor-Like 2, CDI12, or PRR-2, is a
single pass transmembrane glycoprotein with two Ig-like C2-type domains and an Ig-like V-type domain) with high affinity and specificity and inhibit its binding to
TIGIT and / or CD112R. The antibodies recognize the
Nectin-2
protein (CD112), prevent its binding to
T cell immunoreceptor with Ig and ITIM domains (
TIGIT) and CD112R (PVRIG) and inhibit suppressive activity on lymphocytes such as natural killer (NK) cells and T-cells. The disclosure further provides pharmaceutical and methods for use in
cancer immunotherapy and in diagnosis. The disclosure finally further provides
chimeric antigen receptor (CAR) comprising scFv
antibody binding to Nectin-2.
