The efficacy of immunotherapy in glioma requires distal B cell responses in tumor-draining lymph nodes.

Understanding how the immune system fights glioma reveals why combining certain therapies might work better than using them alone.

CTLA-4 blockade efficacy in glioma mouse models requires germinal center B cell activation in tumor-draining cervical lymph nodes, with glioma-reactive IgG antibodies accumulating in the tumor microenvironment and promoting phagocytosis. This unexpected requirement for distal humoral immunity suggests that combination strategies targeting germinal center responses may enhance checkpoint immunotherapy efficacy in glioblastoma.
