Adipose tissue plays essential roles in maintaining lipid and glucose homeostasis. To date several types of adipose tissue have been identified, namely white, brown, and beige, that reside in various specific anatomical locations throughout the body. The cellular composition, secretome, and location of these adipose depots define their function in health and metabolic disease. In obesity, adipose tissue becomes dysfunctional, promoting a pro-inflammatory, hyperlipidemic and insulin resistant environment that contributes to type 2 diabetes mellitus (T2DM). Concurrently, similar features that result from adipose tissue dysfunction also promote cardiovascular disease (CVD) by mechanisms that can be augmented by T2DM. The mechanisms by which dysfunctional adipose tissue simultaneously promote T2DM and CVD, focusing on adipose tissue depot-specific adipokines, inflammatory profiles, and metabolism, will be the focus of this review. The impact that various T2DM and CVD treatment strategies have on adipose tissue function and body weight also will be discussed.
脂肪组织在维持脂质和葡萄糖稳态方面发挥着重要作用。迄今为止,已鉴定出几种类型的脂肪组织,即白色、棕色和米色脂肪组织,它们存在于全身各个特定的解剖位置。这些脂肪库的细胞组成、分泌组和位置决定了它们在健康和代谢疾病中的功能。在肥胖症中,脂肪组织功能失调,促进促炎、高脂血症和胰岛素抵抗环境,从而导致2型糖尿病(T2DM)。同时,脂肪组织功能障碍导致的类似特征也通过可被T2DM增强的机制促进心血管疾病(CVD)。功能失调的脂肪组织同时促进T2DM和CVD的机制,重点关注脂肪组织库特异性脂肪因子、炎症特征和代谢,将是本综述的重点。还将讨论各种T2DM和CVD治疗策略对脂肪组织功能和体重的影响。
