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.
Chemicals and particulates may slip across the blood-brain barrier or travel up olfactory nerves to directly affect brain cells. What are the consequences for cognition?
According to a structural analysis, fluorescently tagged tau fragments cannot form paired helical filaments. This suggests the assay does not measure prion-like propagation.
Harvard or MIT? The microbiomes of mice raised in different facilities dictated their response to C9 deficiency, including whether they died young. Do gut microbes influence ALS?
