KLRC1 and neoplasm: Notably, CD8+ T and NK cells in tumor were significantly more numerous than those in blood (Figures 5(D), 6(D), and S12(B)), indicating that αNKG2A-N215 treatment predominantly induced intratumoral antitumor immune responses, which was consistent with the higher expression of NKG2A in tumor-infiltrated immune effector cells (Figures 2 and S3).
