T cells from SLE patients (227, 228) and lupus-prone mice (229) have abnormally high expression of CaMK4, which activates the AKT-mTOR pathway to promote Th17 cell development and IL-17 release.Th17 cell differentiation can be considerably decreased by blocking the CaMK4-AKT-mTOR pathway (230). Here, MTOR is linked to systemic lupus erythematosus.
