摘要

慢性肾脏病(CKD)是指肾脏功能持续丧失(3 个月),其发病率越来越高(占全球人口的 10%),但治疗方法却很有限。细胞外基质异常积聚导致的纤维化是几乎所有类型的肾脏慢性重复损伤的最终共同途径,被认为是 CKD 的标志。肌成纤维细胞是产生细胞外基质的关键细胞,受损肾小管和免疫细胞之间的串扰激活了肌成纤维细胞。新的证据表明,新陈代谢的改变会影响细胞的生物能和代谢信号,是肾脏纤维化发病机制的关键因素。免疫细胞的功能与其代谢特征密切相关,肾脏细胞似乎会因损伤而发生细胞类型特异性代谢转变,所有这些都能决定慢性肾脏病的损伤和修复反应。详细了解不同肾脏细胞亚群代谢重编程的异质性对于阐明细胞类型之间的交流过程以及开发基于代谢的慢性肾脏病创新治疗策略至关重要。

Metabolism at the crossroads of inflammation and fibrosis in chronic kidney disease

Metabolism at the crossroads of inflammation and fibrosis in chronic kidney disease

Chronic kidney disease (CKD), defined as persistent (>3 months) kidney functional loss, has a growing prevalence (>10% worldwide population) and limited treatment options. Fibrosis driven by the aberrant accumulation of extracellular matrix is the final common pathway of nearly all types of chronic repetitive injury in the kidney and is considered a hallmark of CKD. Myofibroblasts are key extracellular matrix-producing cells that are activated by crosstalk between damaged tubules and immune cells. Emerging evidence indicates that metabolic alterations are crucial contributors to the pathogenesis of kidney fibrosis by affecting cellular bioenergetics and metabolite signalling. Immune cell functions are intricately connected to their metabolic characteristics, and kidney cells seem to undergo cell-type-specific metabolic shifts in response to damage, all of which can determine injury and repair responses in CKD. A detailed understanding of the heterogeneity in metabolic reprogramming of different kidney cellular subsets is essential to elucidating communication processes between cell types and to enabling the development of metabolism-based innovative therapeutic strategies against CKD.
