Ablation of PRDM16 and Beige Adipose Causes Metabolic Dysfunction and a Subcutaneous to Visceral Fat Switch
A clear relationship exists between visceral obesity and type 2 diabetes, whereas subcutaneous obesity is comparatively benign. Here, we show that adipocyte-specific deletion of the coregulatory protein PRDM16 caused minimal effects on classical brown fat but markedly inhibited beige adipocyte function in subcutaneous fat following cold exposure or β3-agonist treatment. These animals developed ...
متن کاملBioengineering Beige Adipose Tissue Therapeutics
Unlocking the therapeutic potential of brown/beige adipose tissue requires technological advancements that enable the controlled expansion of this uniquely thermogenic tissue. Transplantation of brown fat in small animal model systems has confirmed the expectation that brown fat expansion could possibly provide a novel therapeutic to combat obesity and related disorders. Expansion and/or stimul...
متن کاملAge-dependent differences in brain tissue microstructure assessed with neurite orientation dispersion and density imaging.
Human aging is accompanied by progressive changes in executive function and memory, but the biological mechanisms underlying these phenomena are not fully understood. Using neurite orientation dispersion and density imaging, we sought to examine the relationship between age, cellular microstructure, and neuropsychological scores in 116 late middle-aged, cognitively asymptomatic participants. Re...
متن کاملActivated Type 2 Innate Lymphoid Cells Regulate Beige Fat Biogenesis
Type 2 innate lymphoid cells (ILC2s), an innate source of the type 2 cytokines interleukin (IL)-5 and -13, participate in the maintenance of tissue homeostasis. Although type 2 immunity is critically important for mediating metabolic adaptations to environmental cold, the functions of ILC2s in beige or brown fat development are poorly defined. We report here that activation of ILC2s by IL-33 is...
متن کاملWhite adipose tissue sympathetic nervous system denervation increases fat pad mass and fat cell number.
The sympathetic nervous system (SNS) drive on white adipose tissue (WAT) was varied to test its effects on fat cell number (FCN) under conditions in which lipolysis would be minimized and therefore partially separable from SNS trophic effects. The inguinal subcutaneous WAT (IWAT) pad of Siberian hamsters was chosen because 1) it is innervated by the SNS, 2) short day (SD) exposure increases its...
