We further conducted the intracerebral implantation of rodent glioma cells into the animals and found that the volumes of tumors formed by rat C6 glioma cells or mouse GL261 glioma cells were significantly larger in the cortex of TNFR2−/− mice when compared to that measured in LPS-primed WT or LPS-primed TNFR2+/− mice. This evidence concerns the gene TNFRSF1B and central nervous system cancer.
