WebMacrophage infiltration of white adipose tissue (WAT) is implicated in the metabolic complications of obesity. The precipitating event(s) and function(s) of macrophage infiltration into WAT are unknown. We demonstrate that >90% of all macrophages in WAT of obese mice and humans are localized to d … To examine the role of IRF3 in adipogenesis, pre-adipocytes from WT and KO mice were isolated from both vWAT and sWAT for adipocyte differentiation. IRF3 expression and activation were found to be induced on day 5 after initiation of differentiation and greatly increased on days 7–9 (Fig. 3a). … See more To understand the role of IRF3 in metabolism, we fed C57BL/6 mice with a HFD for 8 and 16 weeks to examine the expression of IRF3.
