Graphical representation of exercise/IL-6 via the JAK2/TUB axis in the hypothalamus. Acute exercise (swimming) or IL-6 treatment ICV induces TUB tyrosine phosphorylation and its association with JAK2 in the hypothalamus of mice. The activation of the IL-6/Tubby axis reduces food intake. Therefore, acute exercise or IL-6 via the activation of the IL-6/JAK2/Tubby axis reduces feeding.
