摘　　要：新生儿期的免疫系统发育阶段对维持新生儿健康至关重要,具有独特的免疫调节机制。近年来,人们越来越关注髓源性抑制细胞(MDSCs)在新生儿免疫调节中的作用。MDSCs是一类免疫抑制功能强大的异质性细胞群体,它们能够通过多种机制调节免疫应答。MDSCs在新生儿中的调节作用对防止过度免疫反应和促进免疫耐受至关重要,有助于预防新生儿期炎症性疾病,并对其后续健康产生积极影响。近期研究文献分析展示了MDSCs在新生儿免疫调节中的多种作用机制,包括在特定病理条件下的保护作用、与新生儿期炎症反应的相互作用,以及对长期免疫发展的潜在影响。因此,深入理解MDSCs在新生儿免疫中的角色,不仅有助于揭示其复杂的调节机制,也为制定新的预防和治疗新生儿炎症性疾病的策略提供了新的思路。The developmental stage of the immune system during the neonatal period is crucial for maintaining neonatal health,characterized by unique immunoregulatory mechanisms.In recent years,increasing attention has been drawn to the role of myeloid-derived suppressor cells(MDSCs)in neonatal immune regulation.MDSCs represents a heterogeneous population of cells with potent immunosuppressive functions,capable of modulating immune responses through various mechanisms.The regulatory role of MDSCs in neonates is vital for preventing excessive immune reactions and promoting immune tolerance,thereby aiding in the prevention of neonatal inflammatory diseases and positively influencing subsequent health outcomes.Analysis of recent research literature reveals multiple mechanisms through which MDSCs contribute to neonatal immune regulation,including protective effects under specific pathological conditions,interactions with neonatal inflammatory responses,and potential impacts on long-term immune development.Therefore,a comprehensive understanding of the role of MDSCs in neonatal immunity not only helps elucidate their intricate regulatory mechanisms but also provides novel insights for developing strategies for the prevention and treatment of neonatal inflammatory diseases.
