Title	Multi-compartment quantitative proteomics revealing potential mechanisms underlying the treatment effects of mesenchymal-derived extracellular vesicles in a monkey model of cortical injury
Description	Cortical injury frequently causes motor dysfunction, significantly impairing activities of daily living, and currently, there are no effective therapeutic options available. Previous studies demonstrated that intravenous infusion of mesenchymal stromal cell-derived extracellular vesicles (MSC-EVs) exerts beneficial effects following cortical injury in primary motor cortex via reducing injury-induced microglial neuroinflammation, neuronal excitotoxicity, synapse loss, oligodendrocyte damage and myelination deficits in the rhesus monkey. However, the specific molecules within MSC-EVs responsible for these therapeutic effects and the underlying molecular mechanisms remain largely unexplored. In this study, employing quantitative proteomics strategy, we first identified the protein composition of MSC-EVs, then analyzed the global protein expression changes associated with cortical injury and treatment effect in brain tissue, cerebrospinal fluid (CSF), and plasma samples from monkeys following cortical injury. A total of 4124/1241/431 monkey proteins were reliably quantified in tissue/CSF/plasma samples, respectively. Further informatics analysis revealed not only the enriched biological processes aligned with previous findings, but also several potential treatment markers. This first-time comprehensive investigation of quantitative proteomics in multi-compartment samples from rhesus monkey enhanced our understanding of the treatment effects of MSC-EVs, paving the way for novel treatment and biomarker discovery.
