Causal relationships between peripheral immune cells and Alzheimer's disease: a two-sample Mendelian randomization study.

Objective: Previous research suggests that peripheral immune cells may play a role in the development of Alzheimer's disease (AD). Our study aims to determine if the composition of peripheral immune cells directly contributes to the occurrence of AD.

Methods: We utilized a two-sample Mendelian randomization (MR) approach to examine the association between peripheral immune cells and AD.
