研究设计:

连续入组 

Study design:

Sequential 

研究目的:

阐明Cbl-b是否通过对海马小胶质细胞DBC1泛素化修饰,导致SIRT1蛋白增加,从而抑制NLRP3炎性小体活化及延缓老年PND的进展,为老年PND的发病机制及治疗策略提供理论依据。  

Objectives of Study:

To elucidate whether Cbl-b inhibits NLRP3 inflammasome activation and delays the progression of elderly PND by ubiquitinating hippocampal microglial DBC1, leading to an increase in SIRT1 protein, thereby providing a theoretical basis for the pathogenesis and treatment strategies of elderly PND.
