Abstract: Natural killer (NK) cell killing of various tumors is inhibited in the presence of ligands of TIGIT, an inhibitory receptor present on all human NK cells and on various T cells. Monoclonal antibodies that recognize TIGIT and inhibit its suppressive activity on T-cells are provided as well as pharmaceutical compositions comprising them and methods for their use in cancer immunotherapy and in diagnosis and treatment of immune disorders.

Abstract: The present invention provides monoclonal antibodies that recognize human CD 112R with high affinity and specificity and inhibit its binding to Nectin-2. The present invention further provides pharmaceutical compositions comprising the antibodies and methods for their use in cancer immunotherapy and in diagnosis.

Abstract: The present invention provides monoclonal antibodies that recognize poliovirus receptor (PVR) and inhibit its binding to T cell immunoreceptor with Ig and ITIM domains (TIGIT). The present invention further provides pharmaceutical compositions comprising the antibodies and methods for their use in cancer immunotherapy, treating infections and in diagnosis.
