Popis: Dysfunction of adipocytes and adipose tissue is a primary defect in obesity and obesity-associated metabolic diseases. Interferon regulatory factor 3 (IRF3) has been implicated in adipogenesis. However, the role of IRF3 in obesity and obesity-associated disorders remains unclear. Here, we show that IRF3 expression in human adipose tissues is positively associated with insulin sensitivity and negatively associated with type 2 diabetes. In mouse pre-adipocytes, deficiency of IRF3 results in increased expression of PPARγ and PPARγ-mediated adipogenic genes, leading to increased adipogenesis and altered adipocyte functionality. The IRF3 knockout (KO) mice develop obesity, insulin resistance, glucose intolerance, and eventually type 2 diabetes with aging, which is associated with the development of white adipose tissue (WAT) inflammation. Increased macrophage accumulation with M1 phenotype which is due to the loss of IFNβ-mediated IL-10 expression is observed in WAT of the KO mice compared to that in wild-type mice. Bone-marrow reconstitution experiments demonstrate that the nonhematopoietic cells are the primary contributors to the development of obesity and both hematopoietic and nonhematopoietic cells contribute to the development of obesity-related complications in IRF3 KO mice. This study demonstrates that IRF3 regulates the biology of multiple cell types including adipocytes and macrophages to prevent the development of obesity and obesity-related complications and hence, could be a potential target for therapeutic interventions for the prevention and treatment of obesity-associated metabolic disorders This study was supported by grants from the National Medical Research Council (OFIRG/0059/2017) of Singapore (to YZ), A*STAR-NHMRC (bilateral grant NHMRC2017-SG006 to YZ), the National Research Foundation, Prime Minister’s Office, Singapore under its Campus of Research Excellence and Technological Enter- prise (CREATE) Programme (to YZ), the NUS Global Asia Institute (R571-000-043-133 to YZ), British Heart Foundation (Programme Grant RG/18/7/33636 to AVP), Medical Research Council (MRC_MC_UU_12012/2 to AVP, and Medical Research Council Disease Model Core facilities of the Wellcome Trust-MRC MDU (MRC_MC_UU_12012/5 to AVP), SGR 2017/00734 (to JF) and PI18/01022 (to JF)
