促炎细胞因子白细胞介素(IL)-17(也称为IL-17 A)与组织炎症的诱导有关。肥胖个体表现出慢性低度炎症的许多症状,表明IL-17 A可能影响脂肪组织。然而,IL-17 A在肥胖中的作用在很大程度上未被探索。新出现的研究表明,肥胖选择性地促进Th 17 T细胞谱系的扩增,加重自身免疫性小鼠模型如EAE和结肠炎的疾病。人体研究支持这一概念,因为新的临床研究表明,IL-17 A在肥胖个体中的表达水平升高。然而,相反,IL-17 A的抗脂肪形成作用变得明显,因此IL-17 A和脂肪代谢之间的相互联系可能相当复杂。在这里,我们巩固了IL-17与肥胖相关的潜在影响,并描述了有关IL-17 A在脂肪组织中作用的新数据。
The pro-inflammatory cytokine interleukin (IL)-17 (also known as IL-17A) has been associated with induction of tissue inflammation. Obese individuals exhibit many symptoms of chronic low-grade inflammation, suggesting that IL-17A may impact adipose tissue. However, the role of IL-17A in obesity is largely unexplored. Emerging studies indicate that obesity selectively promotes expansion of the Th17 T-cell lineage, exacerbating disease in murine models of autoimmunity such as EAE and colitis. Human studies support this concept, as new clinical studies suggest that IL-17A is expressed at elevated levels in obese individuals. Conversely, however, an anti-adipogenic role for IL-17A is becoming evident, and therefore the interconnections between IL-17A and fat metabolism may be quite complex. Here, we consolidate the potential implications of IL-17 in relation to obesity and describe the emerging data regarding the role of IL-17A in adipose tissue.
