Massive Proteomics Studies Peg Glial Metabolism, Myelination, to AD

RESEARCH NEWS 2020-05-23 Research News RNA sequencing studies of postmortem human brain samples have generated massive datasets implicating all manner of biological functions in Alzheimer’s disease. But how do these findings translate to proteins—where the biological rubber meets ...

Without TMEM106B, Lysosomal Traffic Jams Wreak Havoc in Neurons

RESEARCH NEWS 2020-03-11 Research News TMEM106b, a gene carrying risk variants for frontotemporal dementia (FTD), coordinates the steady stream of lysosomal traffic along axons, according to a study published March 10 in Cell Reports. Researchers led by Markus Damme of Christian ...

Different CSF Phospho-Taus Match Distinct Changes in Brain Pathology

RESEARCH NEWS 2020-03-13 Research News The phosphorylation of tau in the Alzheimer’s brain is not a binary state. It evolves over time, passing through distinct stages that reflect worsening disease, according to a study in the March 11 Nature Medicine led by Randall Bateman and ...

217—The Best Phospho-Tau Marker for Alzheimer’s?

CONFERENCE COVERAGE 2020-04-10 Conference Coverage A flood of recent data seems to leave little doubt that phospho-tau217 is the better of the soluble tau markers for studying Alzheimer’s disease thus far. At this year’s virtual AAT-AD/PD meeting, Oskar Hansson, Lund University, Sweden ...

Does Alzheimer’s Start in the Heart of the Cholinergic System?

CONFERENCE COVERAGE 2020-04-16 Conference Coverage Three the approved drugs for Alzheimer’s disease attempt to boost the brain’s supply of acetylcholine, a critical neurotransmitter for cognition that wanes in people with the disease. But might crumbling of the brain’s cholinergic ...
