Infliximab therapy restores adiponectin expression in perivascular adipose tissue and improves endothelial nitric oxide-mediated vasodilation in mice with type 1 diabetes

Increased TNFα-mediated JNK signaling in the perivascular adipose tissue (PVAT) may contribute to the pathogenesis of vascular complications in T1DM by reducing adiponectin (Ad) synthesis and therefore impairing Ad-mediated activity in the contiguous blood vessel system. We evaluated whether in vivo treatment with the TNFα blocking antibody infliximab normalized expression of Ad and Ad receptors in various fat depots, and whether this effect...
