The contemporary ideas on endocrine function of the adipose tissue and its role in pathogenesis of diabetes mellitus and insulin resistance associated with it and the metabolic syndrome are shown in the review. A change in the life style (excessive and irrational nutrition, insufficient physical loading, psychological disorders) and also the reduction of genetic and immunologic controlling mechanisms contribute to the development of obesity, that is now considered as low-grade inflammation. An increased number of small size adipocytes and macrophages of the adipose tissue begin to secrete an increase number of proinflammatory adipocytokines and chemokines that result in the inflammatory and metabolic stress accompanied by the stimulation of signal pathways, leading to increased insulin requirement, on the one hand, and promoting to the beta-cell death, on the other hand. The role of some adipocytokines such as IL-6, TNF-alpha, leptin, adiponectin, visfatin and resistin was demonstrated in these processes.
这篇综述展示了关于脂肪组织内分泌功能及其在糖尿病发病机制、与之相关的胰岛素抵抗和代谢综合征中作用的当代观点。生活方式的改变(过度和不合理饮食、体力活动不足、心理障碍)以及遗传和免疫控制机制的减弱导致了肥胖的发生,现在肥胖被认为是一种低度炎症。脂肪组织中小尺寸脂肪细胞和巨噬细胞数量的增加开始分泌更多的促炎脂肪因子和趋化因子,这会导致炎症和代谢应激,一方面伴随着信号通路的刺激,导致胰岛素需求增加,另一方面促进β细胞死亡。在这些过程中,一些脂肪因子如白细胞介素-6、肿瘤坏死因子-α、瘦素、脂联素、内脏脂肪素和抵抗素的作用得到了证实。
