研究目的:

本研究旨在围绕环境微/纳塑料暴露与先天性巨结肠发生发展的关系,结合临床组织、细胞实验及动物模型,系统评估纳米塑料对肠神经元的损伤效应及其健康风险,并进一步从蛋氨酸代谢重编程和JAK/STAT通路激活角度探讨其诱导肠神经元细胞毒性与凋亡的分子机制,为阐明先天性巨结肠的环境致病机制及寻找潜在干预靶点提供理论依据。  

Objectives of Study:

This study aimed to investigate the role of environmental micro/nanoplastic exposure in the development and progression of Hirschsprung’s disease, to evaluate its damaging effects and potential health risks on enteric neurons through clinical tissue analysis, cell experiments, and animal models, and to further elucidate the molecular mechanism by which methionine metabolic reprogramming-mediated JAK/STAT pathway activation promotes enteric neuronal cytotoxicity and apoptosis, thereby providing a theoretical basis for clarifying the environmental pathogenesis of Hirschsprung’s disease and identifying potential therapeutic targets.
