Fig. 3From: Enhanced immunity in a mouse model of malignant glioma is mediated by a therapeutic ketogenic dietThe ketogenic diet reduces expression of immune inhibitory receptors and ligands expressed in glioma tumors. Expression of the immune inhibitory receptors, PD-1 (a) and CTLA-4 (b) on infiltrating CD8 T cells isolated from tumors from mice fed each diet were assessed. Expression of the immune inhibitory ligands, CD86 (c) and PD-L1 (d), on GL261-Luc2 tumor tissue was also assessed.
