脂肪组织包含多种细胞类型。其中存在的更丰富的细胞类型是脂肪细胞、前脂肪细胞、免疫细胞和内皮细胞。在过量热量摄入期间,这些细胞必须调整和重塑,以适应对甘油三酯储存的增加需求。在对脂肪组织总分泌组进行全面分析的基础上,本文综述了脂肪因子生物学的三个领域:A)在肥胖的发展过程中脂肪组织的细胞外基质发生了什么变化; B)脂肪细胞本身是否在先天免疫反应中发挥作用;以及C)脂肪组织的血管生成特征如何与胰岛素抵抗的发展联系起来?脂肪细胞是一种非常活跃的内分泌细胞。虽然有丰富的信息,不同的脂肪因子的转录调控,只有有限的数据,翻译后过程如何影响这些分泌分子在细胞外环境中的蛋白质水平。这个过程是如何调节的,在肥胖的背景下,它在多大程度上导致脂肪因子失调?为了实现这一目标,我们提出了一个全面的概述,目前所有可用的分泌脂肪组织的产品,已确定在蛋白质水平。
Adipose tissue contains a vast variety of cell types. Amongst the more abundant cell types present are adipocytes, pre-adipocytes, immune cells and endothelial cells. During times of excess caloric intake, these cells have to adjust and remodel in order to accommodate the increased demand for triglyceride storage. Based on a comprehensive analysis of the total adipose tissue secretome, this review focuses on three areas of adipokine biology: A) what changes does the extracellular matrix of adipose tissue during the development of obesity; B) does the adipocyte per se play a role in the innate immune response; and C) how is the angiogenic profile of adipose tissue linked to the development of insulin resistance? The adipocyte is a very active endocrine cell. While there is a wealth of information on the transcriptional regulation of the different adipokines, there is only limited data available on how post-translational processes affect the protein levels of these secretory molecules in the extracellular environment. How is this process regulated and to what extend does it contribute to adipokine dysregulation in the context of obesity? To achieve that, we present a comprehensive overview of all of the currently available secreted adipose tissue products that have been identified at the protein level.
