The skin is one of the most vital organs in the human body, and skin wounds caused by various factors can severely impact patients’ physical and mental health. Among the therapeutic strategies for skin wound repair, mesenchymal stem cell-derived exosomes (MSC-Exos) have emerged as a promising biological therapy, attracting significant attention in related research. As critical mediators of stem cell biological effects, MSC-Exos fuse with target cells and transfer bioactive proteins and nucleic acids from stem cells into recipient cells. These exosomes modulate inflammatory responses, promote cell proliferation, migration, and angiogenesis, and regulate extracellular matrix remodeling, thereby accelerating wound healing. In recent years, studies on the mechanisms by which exosomes promote skin wound repair have advanced and refined continuously. This article summarized the key signaling pathways through which MSC-Exos participate in skin wound repair, aiming to enhance the understanding of their roles in facilitating wound healing.

Objective:To identify potential therapeutic targets for the treatment of hair color and hair shaft abnormalities, thereby offering innovative insights and strategies for the management of the associated conditions.Methods:Using the protein quantitative trait locus(pQTL) data derived from extensive proteomics studies, a two-sample Mendelian randomization was conducted to preliminarily identify potential drug therapeutic targets. Following this, sensitivity analyses were performed to evaluate potential confounding factors, including heterogeneity and horizontal pleiotropy. A leave-one-out sensitivity analysis was also conducted, systematically excluding each single nucleotide polymorphism (SNP) to evaluate their individual impact. Additionally, co-localization analysis was carried out to determine the presence of shared genetic variants between the identified plasma proteins and the relevant traits.Results:The proteomic data analyzed in this investigation encompassed 4 907 pQTLs, while the genetic data pertaining to hair pigmentation and shaft abnormalities included 124 cases and 432 686 controls. Through the Mendelian randomization screening, six candidate protein genes were identified: HLA-DQA2, CTSB, KIR2DS2, SVEP1, HOMER2, and HOMER1. Sensitivity analyses revealed no evidence of heterogeneity or horizontal pleiotropy among these proteins. The leave-one-out sensitivity analysis demonstrated that no single SNP significantly affected the overall findings. Notably, HOMER2 was substantiated by co-localization analysis, which provided robust evidence of its potential role in regulating the genetic mechanisms associated with hair pigmentation and shaft integrity.Conclusion:This study successfully identified six potential therapeutic targets for hair pigmentation and shaft abnormalities, with HOMER2 exhibiting the most compelling evidence. These findings pave the way for novel therapeutic approaches in the treatment of hair color and hair shaft disorders.
