新生儿缺氧缺血性脑损伤(HIBD)后神经系统修复尚无特效疗法,是医学界研究的难点与热点。自噬作为一种细胞自我修复机制,在不同阶段通过不同的信号途径发挥作用,但其在HIBD不同阶段的具体作用和机制尚未完全阐明。本文回顾了近些年有关自噬在新生儿期HIBD不同阶段的研究结果:在缺氧缺血的急性期,自噬活性明显增加,其保护或损伤作用仍存在争议;而在亚急性及慢性期,自噬可能对神经元存在促死亡和神经修复双重作用;在后遗症期,自噬相关研究尚不充分,但脑瘫患儿自噬相关基因(ATG)的表达水平揭示了自噬在HIBD后的正反两面性。从整体研究来看,适度的自噬水平有助于清除受损组分和毒性蛋白,发挥神经保护作用。进一步研究自噬在HIBD中的作用和机制,将有助于开发基于自噬的HIBD防治策略,提高患儿的生存率和生活质量。
