1323-T Cell Dynamics in Gastric Cancer Response
This study utilizes longitudinal single-cell RNA and TCR sequencing to examine how immune cells transform during frontline chemoimmunotherapy for advanced gastric cancer. By analyzing serial biopsies, researchers identified that patients with prolonged survival maintain a high abundance of progenitor-exhausted T cells that exhibit stem-like qualities and tumor reactivity. These favorable outcomes are further supported by the recruitment of B cells, which interact with T cells to promote their persistence and anti-tumor activity. Additionally, the data suggests that effective immune responses…
