✓ Peer-reviewed alzhub usefulness score 34 out of 100. Down syndrome and Alzheimer's

Topic: Brain proteins, microglia and lab models

Down syndrome (trisomy 21) is a genetic disease with developmental brain abnormalities resulting in early mental retardation and precocious, age dependent Alzheimer-type neurodegeneration. We tried to discuss the role of neurodevelopmental abnormalities in connection with aberrant expression of genes on chromosome 21 including amyloid precursor protein (APP), CuZn superoxide dismutase (SOD1) and glial-derived S100 beta protein for neurodegeneration in DS. In this model, alterations in developmental pathways due to aberrant gene expression can impair cellular homeostasis and predispose to neurodegeneration of certain brain regions and types of nerve cells, involving cholinergic, serotonergic and catecholaminergic transmission, by shifting balance toward a pro-apoptotic state.

Key findings

Why it matters

This review discusses how developmental brain abnormalities in Down syndrome, together with aberrant expression of genes on chromosome 21 including APP, SOD1, and S100 beta, may predispose certain brain regions and nerve cell types to age-dependent Alzheimer-type neurodegeneration. It presents a model involving cholinergic, serotonergic, and catecholaminergic transmission shifting toward a pro-apoptotic state, but offers no treatment 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 33 of the 96 points we could judge it on, which is 34 out of 100.
