Atherosclerosis, a key pathological basis of cardio-cerebrovascular diseases, is closely associated with aging and endothelial cell senescence. The role of microRNAs (miRNAs) in regulating endothelial cell senescence and atherosclerosis remains incompletely understood. In this study, we discovered that miR-375-3p expression was significantly elevated in the serum of both aged and atherosclerotic mice. Overexpression of miR-375-3p induced endothelial cell senescence, evidenced by increased...

INTRODUCTION: The aging global population underscores the need to understand brain aging and its links to neurodegenerative diseases. While most brain aging studies use cognitive impairment as exclusion criteria, preclinical biomarkers may influence results, potentially masking early pathological effects. This study evaluates how preclinical AD and vascular biomarkers impact brain aging models in cognitively normal subjects.
