肥胖被定义为一种慢性低度炎症状态,伴有免疫细胞逐渐浸润到脂肪组织中。脂肪组织巨噬细胞在慢性炎症状态和代谢功能障碍的形成中起着关键作用。促炎巨噬细胞被募集到肥胖脂肪组织这一新颖发现,促使人们对免疫细胞和代谢之间的相互作用产生了更大的兴趣。自这一发现以来,已经发表了许多研究巨噬细胞募集的因素、脂肪组织巨噬细胞表型变化以及代谢功能障碍的著作。脂肪因子和趋化因子是关键的介质,在脂肪细胞和巨噬细胞之间的串扰以及调节脂肪组织炎症中起着至关重要的作用。在本综述中,我们讨论了肥胖介导的脂肪组织重塑,特别是脂肪因子/趋化因子在巨噬细胞募集到肥胖脂肪组织中的作用。本综述为这些因素的生理作用提供了新的见解,并确定了肥胖及相关疾病的一个潜在治疗靶点。
Obesity is characterized as a chronic state of low-grade inflammation with progressive immune cell infiltration into adipose tissues. Adipose tissue macrophages play critical roles in the establishment of the chronic inflammatory state and metabolic dysfunctions. The novel discovery that pro-inflammatory macrophages are recruited to obese adipose tissue prompted an increased interest in the interplay between immune cells and metabolism. Since this discovery, many works have been published investigating the factors that lead to macrophage recruitment, the phenotypic change of adipose tissue macrophages, and metabolic dysfunctions. Adipokines and chemokines are key mediators that play crucial roles in crosstalk between adipocytes and macrophages and in regulating the adipose tissue inflammation. In the present review, we discuss the obesity-mediated adipose tissue remodeling, and particularly, the role of adipokines/chemokines in macrophage recruitment to obese adipose tissue. This review provides new insights into the physiological role of these factors and identifies a potential therapeutic target for obesity and associated disorders.
