摘要:

既往研究发现,乙醇处理过的星形胶质细胞和长期饮酒的小鼠体内的 NLRP3(含 NODLRR pyrin 结构域的蛋白 3-炎症小体复合物的激活可能与神经炎症和脑损伤有关。间充质干细胞源性细胞外囊泡(MSC-EVs)可减轻前额叶皮层的神经炎症反应、髓鞘和突触结构改变。此外,它们还能缓解青少年小鼠因酒精暴露而引起的认知和记忆功能障碍。实验探讨了抑制 NLRP3 炎症小体活化的间充质干细胞源性细胞外囊泡是否能减轻酒精暴露青少年小鼠的海马神经炎症。结果显示,间充质干细胞源性细胞外囊泡能改善海马NLRP3炎性体复合体和其他NLRs炎性体(如 IL-1β,IL-18iNOSNF-κBMCP-1 CX3CL1)和 miRNAmiR-21a-5pmiR-146a-5p miR-141-5p)的改变。生物信息学分析进一步揭示了 miR-21a-5p miR-146a-5p 与炎症靶基因和 NOD 样受体信号通路的关系。综上所述,间充质干细胞源性细胞外囊泡可减轻青春期酒精暴露诱发的与NLRP3炎性体激活相关的海马神经炎症反应,因而对青春期酒精暴露的神经炎症具有治疗潜力。

Abstract: Our previous studies have reported that activation of the NLRP3 (NOD-, LRR- and pyrin domain-containing protein 3)-inflammasome complex in ethanol-treated astrocytes and chronic alcohol-fed mice could be associated with neuroinflammation and brain damage. Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) have been shown to restore the neuroinflammatory response, along with myelin and synaptic structural alterations in the prefrontal cortex, and alleviate cognitive and memory dysfunctions induced by binge-like ethanol treatment in adolescent mice. Considering the therapeutic role of the molecules contained in mesenchymal stem cell-derived extracellular vesicles, the present study analyzed whether the administration of mesenchymal stem cell-derived extracellular vesicles isolated from adipose tissue, which inhibited the activation of the NLRP3 inflammasome, was capable of reducing hippocampal neuroinflammation in adolescent mice treated with binge drinking. We demonstrated that the administration of mesenchymal stem cell-derived extracellular vesicles ameliorated the activation of the hippocampal NLRP3 inflammasome complex and other NLRs inflammasomes (e.g., pyrin domain-containing 1, caspase recruitment domain-containing 4, and absent in melanoma 2, as well as the alterations in inflammatory genes (interleukin-1β, interleukin-18, inducible nitric oxide synthase, nuclear factor-kappa B, monocyte chemoattractant protein-1, and C–X3–C motif chemokine ligand 1) and miRNAs (miR-21a-5p, miR-146a-5p, and miR-141-5p) induced by binge-like ethanol treatment in adolescent mice. Bioinformatic analysis further revealed the involvement of miR-21a-5p and miR-146a-5p with inflammatory target genes and NOD-like receptor signaling pathways. Taken together, these findings provide novel evidence of the therapeutic potential of MSC-derived EVs to ameliorate the hippocampal neuroinflammatory response associated with NLRP3 inflammasome activation induced by binge drinking in adolescence.
