TRAF5 and metabolic syndrome: The antiviral innate immune system related mitochondrial common adaptor protein MAVS (p = 0.002) is highly expressed in MetS, whereas tumor necrosis factor (TNF) receptor-associated factors TRAF2 (p = 0.041), TRAF3 (p = 0.036), and TRAF5 (p = 0.041) are significantly reduced.
