Neoadjuvant chemotherapy-induced immune remodeling in ovarian cancer: implications for TIL dynamics and combination immunotherapy. (PubMed, Front Immunol)
Notably, spatial omics studies further revealed that, after NACT, a subset of CD8+ T cells can be confined within "myelonets" microdomains organized by myeloid cells, where interactions such as NECTIN2-TIGIT impose spatial restriction and induce functional exhaustion of T cells, thereby compromising their effective tumor killing. This review aims to systematically summarize the baseline characteristics and heterogeneity of lymphoid- and myeloid-derived TILs in ovarian cancer, elucidate the mechanisms underlying immune remodeling induced by NACT and their complex relationships with clinical outcomes, and further discuss combination therapeutic strategies and biomarker development based on dynamic TIL changes to enhance the clinical application of precision immunotherapy.
