Induced neurons lacking the Alzheimer’s risk gene can’t properly recycle APP.
Using a form of confocal microscopy and automated software, the method allows researchers to rapidly identify functional synapses within brain structures.
The modeling approach reinforces the idea that tau pathology propagates through the brain’s physical architecture, including neuronal networks.
Built to cross the blood-brain barrier, the vehicle delivers therapeutic antibodies, enzymes, and potentially small molecules such as oligonucleotides.
Umbilical cord stem cells from presenilin 1 E280A carriers, once differentiated into cholinergic-like neurons, pumped out Aβ42 and accumulated phosphorylated tau and apoptotic markers.
In stark contrast to Aβ and tau fibrils, α-synuclein fibrils are asymmetric, comprising two different protofibrils.
