摘要

Lactate-derived lactylation, as an emerging epigenetic mechanism driven by lactic acid metabolism, plays a pivotal bridging role in diabetic kidney disease (DKD), linking metabolic dysregulation to pathological gene expression. Research indicates that lactacidosis exacerbates glomerular injury by promoting mesangial cell activation and podocyte damage, whilst simultaneously disrupting mitochondrial function in the tubules and activating pro-fibrotic pathways, thereby establishing a vicious cycle of metabolic reprogramming and fibrosis. Furthermore, lactate accumulation and lactylation modulate immune cell function, intensifying inflammatory responses. Owing to their multi-targeted properties, natural compounds from traditional Chinese medicine and traditional Chinese medicine compound formulations offer promising intervention strategies for this pathway. Specific agents such as Berberine, baicalin, ginsenoside compound K, and cordycepin have been demonstrated to mitigate renal injury by directly or indirectly reducing lactate production and modulating lactylation levels, thereby suppressing downstream inflammatory and fibrotic responses. This review systematically elucidates the pivotal role of the lactate-lactylation axis in the pathogenesis of DKD, highlighting traditional Chinese medicine's unique potential for precisely regulating this metabolic-epigenetic nexus. It offers innovative insights and strategies for the integrated management of DKD.
