Chemotherapy induces myeloid-driven spatially confined T cell exhaustion in ovarian cancer
Spatial and molecular profiling of 117 tumors before and after chemotherapy reveals a dynamic tumor ecosystem in ovarian cancer. Launonen et al. identify Myelonets as drivers of CD8+ T cell exhaustion and demonstrate that NECTIN2-TIGIT signaling predicts preclinical immune checkpoint blockade response, unlocking new therapeutic strategies for high-grade serous carcinoma.
