Natural killer cell dysfunction in glioma: from immune evasion to immunotherapy. (PubMed, Front Immunol)
Therapeutic strategies including activation of NK cells via chemotherapeutics (bortezomib, decitabine), blockade of inhibitory receptors (NKG2A, CD161), and combinatorial approaches with immune checkpoint inhibitors are under active investigation. Notably, chimeric antigen receptor (CAR)-engineered NK cells targeting EGFR, HER2, GD2, and CD133 show promise in preclinical glioma models due to their enhanced specificity and reduced toxicity compared to CAR-T cells. This review summarizes the multifaceted roles of NK cells in glioma immunity and highlights novel immunotherapeutic strategies to restore NK cell function and improve clinical outcomes.
