Consequently, TNF-alpha, through activation of p38 MAPK and IKK, produces serine phosphorylation of IR and IRS-1, impairing its tyrosine phosphorylation by insulin and the corresponding activation of phosphatidylinositol 3-kinase and Akt, leading to insulin resistance on glucose uptake and GLUT4 translocation.
