✓ Peer-reviewed alzhub usefulness score 35 out of 100. Down syndrome and Alzheimer's

Topic: Brain proteins, microglia and lab models

This chapter discusses the dependency of basal forebrain cholinergic neurons (BFCNs) on endogenous nerve growth factor (NGF) for the structural and physiologic maintenance of the neuronal cell somata, axonal projections, and terminal synapses. It covers the discovery of NGF and the occurrence of a CNS neurotrophin family and their cognate receptors and their signaling mechanisms. It concludes with a description of the NGF metabolic pathway and its dysregulation in Alzheimer disease (AD) and Down syndrome pathology, explaining the progressive atrophy of BFCNs, which starts at preclinical stages and is reflected in body fluid biomarkers.

Key findings

Why it matters

This chapter describes how basal forebrain cholinergic neurons depend on nerve growth factor and how this pathway is dysregulated in Alzheimer's disease and Down syndrome. It is a mechanistic review and does not report a tested treatment, cure or prevention.

Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, so that was left out: it earned 34 of the 96 points we could judge it on, which is 35 out of 100.
