The concentrations of IL-6 in the cerebellum of animals that died or were killed during the acute phase of the infection (animals fed a L-Vit D diet: n = 12; animals fed a S-VitD diet: n = 7; animals fed a H-VitD diet: n = 8) and of animals killed 20 h after infection (n = 17 for all groups) were significantly decreased in mice fed a H-VitD diet compared with animals fed a L-VitD diet (P < 0.05; Figures 3A, 4A; difference between L-VitD versus S-VitD not significant). Here, IL6 is linked to infection.
