APOE and Alzheimer disease: From the blood of patients with AD, six exosomal miRNAs (adjusted for age, sex, education years, and APOE ε4 status) were identified, which were either upregulated (miR-29c-5p, miR-143-3p, miR-335-5p, and miR-485-5p) or downregulated (miR-138-5p and miR-342-3p) compared to controls.
