Abnormal neuronal and synaptic morphology in Down syndrome brains reproduces in human isogenic cellular models
Abstract Down syndrome (DS) is the most common autosomal aneuploidy compatible with postnatal survival and is caused by full or partial trisomy of chromosome 21. In this study, human isogenic induced pluripotent stem cells (iPSCs) were differentiated into 2D neurons and cortico-striatal assembloids (hCSAs).
Single-cell atlas of the developing Down syndrome brain cortex - Nature Medicine
Abstract Down syndrome (DS), caused by trisomy of chromosome 21, is the leading genetic cause of intellectual disability, yet the mechanisms disrupting fetal brain development remain unclear. We performed single-cell transcriptomic and chromatin accessibility profiling of approximately 250,000 cells from 15 DS and 15 control human fetal cortices (10–20 weeks post-conception).
It’s good to know what to BACE the specificity of your inhibitors on
Abstract Production, aggregation, and clearance of the amyloid β peptide (Aβ) are important processes governing the initial pathogenesis of Alzheimer’s disease (AD). Inhibition of β-site amyloid precursor protein (APP) cleaving enzyme (BACE1) (one of two key proteases responsible for Aβ production) as an AD-therapeutic approach so far has failed to yield a successful drug. BACE1 and its homologue BACE2 are frequently inhibited by the same inhibitors.
Cerebral organoids with chromosome 21 trisomy secrete Alzheimer’s disease-related soluble aggregates detectable by single-molecule-fluorescence and super-resolution microscopy | Molecular Psychiatry
Abstract Understanding the role of small, soluble aggregates of beta-amyloid (Aβ) and tau in Alzheimer’s disease (AD) is of great importance for the rational design of preventative therapies. Here we report a set of methods for the detection, quantification, and characterisation of soluble aggregates in conditioned media of cerebral organoids derived from human iPSCs with trisomy 21, thus containing an extra copy of the amyloid precursor protein (APP) gene.
