NKp30 ligands include B7-H6 and the HLA-B-associated transcript 3 protein (BAT3), also known as BAG6, both able to promote NK cell cytotoxicity against tumor cells and soluble galectin-3 implicated in NK cell tumor evasion (von Strandmann et al., 2007; Brandt et al., 2009; Wang et al., 2014). The gene discussed is NCR3LG1; the disease is neoplasm.
