Plasma cell and cancer stem cell crosstalk in glioblastoma
Plasma cells (PCs) are the main producers of antibodies and have context-dependent roles in tumor immunity. In this issue of Cancer Cell, Gao et al. report that intratumoral PCs drive maintenance of glioblastoma stem cells to promote tumor growth via IgG secretion that activates a FcγRIIA-SYK-AKT signaling axis.
