TLR2 and glioblastoma: For example, Prevotella copri has been reported to produce α‐GalCer in mouse GBM tissue, stimulating γδT cells or invariant natural killer T (iNKT) cells to exert direct or indirect anticancer effects [37], while other strains like Prevotella 7 may promote inflammation via Toll‐like receptor 2 (TLR2)/interleukin‐23 (IL‐23) signaling [36].
