Both type I and II IFN induce insulin resistance by inducing different isoforms of SOCS expression in 3T3-L1 adipocytes
8 Mar 2011
Abstract excerpt
Although elevation of the blood glucose level is a causal adverse effect of treatment with interferon (IFN), the precise underlying molecular mechanism is largely unknown. We examined the effects of type I and type II IFN (IFN-β and IFN-γ) on insulin-induced metabolic signaling leading to glucose uptake in 3T3-L1 adipocytes. IFN-β suppressed insulin-induced tyrosine phosphorylation of IRS-1 without affecting its...
