IL15 and TIGIT blockade enhances the natural killer (NK) cell-mediated activity against MHC-I-deficient melanoma both in vitro and in preclinical models. IL15-induced harnessing of NK cells, associated with their unleashing by TIGIT blockade, may represent a therapeutic approach for tumors, which lack HLA-I molecules thus escaping the CD8+ T...

Antibodies directed towards checkpoint inhibitors have unveiled extraordinary potential in cancer therapy. An article by the Vivier group (Cell 2018;175:1731–1743) shows that blocking the HLA-E-specific NKG2A inhibitory receptor, expressed by NK and inducible in T cells, results in benefits against poor prognosis tumors. Moreover, NKG2A and...
