Enhanced quantity and functionality of natural killer (NK) cells in hepatocellular carcinoma (HCC) have been associated with improved prognosis and survival. Therefore, NK cell-based immunotherapy has been proposed for treating HCC, relying on the activation of NK cell receptors like natural cytotoxicity receptors (NCRs), which recognize specific ligands on HCC cells. However, the effectiveness of this approach remains low due to tumor immune evasion.
