996-Rethinking Immune States in Brain Metastasis
This research challenges the traditional view of breast cancer brain metastases (BCBMs) as being uniformly resistant to the immune system. By analyzing over 150 clinical samples, scientists identified two unique immune niches—specifically TRM-like T cells and tertiary lymphoid structures—that correlate with significantly better patient survival. These distinct environments demonstrate that the brain can host organized, active antitumor responses that do not always mirror the primary tumor's biology. The study also highlights specific microglia-derived macrophage subsets that support these…
