IFNγ — link between infections and cardiometabolic risk?
Viral infections induce muscle insulin resistance in mice through the stimulation of IFNγ. This results in increased insulin levels, which promote antiviral CD8+ T cell activation. In obese mice, insulin resistance triggered by IFNγ also leads to deterioration of glycaemic control. These findings highlight the intricate link between the immune system and metabolic regulation.
