APC and neoplasm: Transcriptomic analysis of Rheb1Δ/Δ GL261 TAM‐MG revealed a re‐education of these cells to an immune reactive and anti‐tumour profile, with an enrichment for pathways linked to the regulation of Th1, Th2 and IFN signalling as well as pathways linked to recruitment, proliferation and priming of APC and cytokine signalling pathways.
