Decreased plasma platelet‐derived growth factor receptor‐β correlates with β‐amyloid, tau, and cognitive decline in male Alzheimer's disease

Abstract

Background: Cerebrospinal fluid (CSF) platelet‐derived growth factor receptor‐β (PDGFRβ) concentration, as well as CSF/plasma albumin ratio (Qalb), have been regarded as the biomarkers reflecting blood‐brain barrier (BBB) damage.
