Recent evidence suggests a significant link between LPCA and metabolic dysregulation, particularly diabetes and dyslipidemia. This review examines the emerging role of metabolism in LPCA pathogenesis and its implications for novel therapeutic approaches. Epidemiologic studies demonstrate increased prevalence of metabolic disorders among patients with LPCA, whereas molecular investigations reveal altered metabolic pathways in affected hair follicles, including disruptions in peroxisome proliferator-activated receptor γ signaling and adenosine monophosphate-activated protein kinase activation, mechanisms that parallel those observed in other fibrotic diseases. These pathways appear to precede inflammatory changes, suggesting metabolic dysfunction as a primary trigger rather than a secondary effect. Preliminary treatments targeting these pathways, such as pioglitazone and metformin, have shown promising results in normalizing lipid metabolism and reducing inflammation, although their clinical efficacy across LPCA subtypes requires further investigation. The review also explores emerging therapeutic possibilities, including glucagon-like peptide-1 agonists. Understanding the interplay between metabolic disturbances, fibrosis, and inflammation in the pathogenesis of LPCA offers new avenues for both research and treatment. This paradigm shift suggests the need for metabolic screening in patients with LPCA and highlights the potential for developing more comprehensive, metabolism-targeted therapies to improve outcomes in these challenging hair disorders.</p>","PeriodicalId":94239,"journal":{"name":"The Journal of investigative dermatology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although fibroblast hyperproliferation and excessive extracellular matrix deposition have been extensively studied, less attention has been paid to the role of vascular dysregulation and endothelial dysfunction (ED) in keloid pathogenesis. Emerging evidence highlights abnormal angiogenesis, vascular irregularities, and endothelial injury as critical drivers of fibrosis in keloids. This review explores the direct and indirect mechanisms of ED in keloid progression, including endothelial-to-mesenchymal transition, inflammation, immune cell crosstalk, and hypoxia. In addition, various treatment strategies targeting angiogenesis and ED, such as drugs, radiotherapy, hyperbaric oxygen therapy, compression, and laser treatments, are comprehensively reviewed. This review explores keloids through the lens of vasculature and endothelium, emphasizing the critical roles of vascular dysregulation and ED. It aims to provide insights into the mechanisms of keloid formation and serve as a reference for developing future therapeutic strategies.</p>","PeriodicalId":94239,"journal":{"name":"The Journal of investigative dermatology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
