[Research progress on cellular metabolic reprogramming in skin fibrotic].

Skin fibrosis is primarily characterized by excessive proliferation of fibroblasts and aberrant accumulation of extracellular matrix, leading to pathological conditions such as hypertrophic scars, keloids, and systemic sclerosis. This dynamic and complex process involves intricate interactions among various resident skin cells and inflammatory cells, ultimately resulting in extracellular matrix deposition and even invasive growth characteristics. The maintenance of cellular phenotypes and functions relies on dynamic metabolic responses, and cellular signal transduction is closely coupled with metabolic processes. Given that the coupling of cell metabolism and signaling in the skin fibrosis microenvironment plays a critical role in inflammatory responses and fibrotic activation, modulating these metabolic pathways may offer novel therapeutic strategies for inhibiting or even reversing the progression of skin fibrosis. This review systematically summarizes the metabolic characteristics of various cell types involved in skin fibrosis, with a focus on core metabolic reprogramming mechanisms such as hyperactive glycolysis, dysregulated fatty acid metabolism, and mitochondrial dysfunction. Furthermore, it explores potential intervention strategies targeting these metabolic pathways, thereby providing new research perspectives for the treatment of skin fibrosis.
