研究目的: |
本研究拟采用体内动物实验、人群流行病调查和分子生物学方法探究环境低剂量镉暴露对 MN 发生发展的影响及肠道菌群-肠肾轴-Th1/Th2 细胞免疫失衡在镉暴露致 MN 发生发展中的作用,从而为进一步阐明 MN 病因及发病机制提供科学依据,并为临床上通过调节肠道菌群失调来治疗 MN 寻求新的靶点。 |

|
Objectives of Study: |
This study intends to use in vivo animal experiments, population epidemiological investigation and molecular biology methods to explore the effects of environmental low-dose cadmium exposure on MN occurrence and development and the role of intestinal microbiota - enterorenal axis -Th1/Th2 cell immune imbalance in MN occurrence and development caused by cadmium exposure, so as to provide scientific basis for further elucidation of MN etiology and pathogenesis. It also seeks a new target for MN treatment by regulating intestinal flora disorder in clinic. |
