Using mass spectrometry to detect teensy amounts of phospho-tau species in plasma, researchers reported that p-tau-217 and p-tau-181 picked out people with Aβ pathology. Differences between groups appear to be huge. An MS-based test for plasma Aβ42 corresponded to brain amyloid, and is going in for regulatory approval.
An expanded set of CSF biomarkers exposed tight connections between p-tau, synaptic dysfunction, and neuroinflammation in people with brain amyloid.
Biogen researchers claim the antibody worked in people who got enough of it. To other researchers, the signal validates the amyloid hypothesis and injects fresh energy into the field. But is this interrupted data set enough to approve?
Prior research has focused on microglia interacting with synapses. New data show they also deal directly with the neuronal cell body. Like little conference rooms, specialized junctions host this communication.
In PASSPORT study, the antibody failed to slow progressive supranuclear palsy. Alzheimer’s trial to continue.
Exposure, Exposure, Exposure? At CTAD, Aducanumab Scientists Make a Case Fluid AD Biomarkers Link P-Tau to Synapses, Inflammation Blood Tests of Phospho-Tau, Aβ42, Track With Brain Amyloid Amyloid Clearance: Check. Cognitive Benefit: Um … Maybe. Picking ...
Researchers link age-related weakening of the barrier to TGFβ signaling, hyperexcitation, and cognitive problems. In rodents, TGFβ antagonists attenuate these effects, reducing seizures.
While gene-based therapy for late-onset AD may seem distant, rare neurological disorders could point the way.
Not Just Blood Pressure—Dietary Salt Linked to Tau Phosphorylation Time to Try Again: Gene-Based Therapy for Neurodegeneration Gene Therapies Enter Trials for Many Brain Pathologies—What about AD? Organized around 10 major themes, this year’s annual ...
As gene therapy is making a comeback, scientists are exploring if it might prevent or reverse Alzheimer’s. Some of those treatments are permanent, heightening safety concerns.
Encouraged by success in treating infant spinomuscular atrophy, researchers are redoubling their efforts to target genetic causes of age-related neurodegeneration.
Specific patterns of expression defined distinct subtypes of neurons, astrocytes, oligodendrocytes, and microglia in this early affected brain region.
Brain biopsy tissue reveals that their transcriptomes shift by location, age, and disease.
In a mouse tauopathy model, knocking out the NLRP3 inflammasome prevented toxic tau from forming.
Based on preclinical data, researchers gave this antibiotic a shot in a two-year clinical trial. It did nothing to slow cognitive decline.
