Chemotherapy riles microglia, causing neurons to turn down expression of BDNF, a growth factor necessary for myelination. Restoring BDNF signaling on oligodendrocytes spared myelin and memory loss.
Much of the neuron loss in rTg4510 mice comes from accidental disruptions in mouse genes rather than expression of mutant tau. Pathology spreads quickly in human tau knock-ins.
Microglia cleanup, mitophagy, axonal plasticity, blood-brain barrier. A renewed focus on ApoE4 is revealing new ways in which this isoform renders the brain vulnerable to Alzheimer’s.
New data from gantenerumab and N3pG confirm that high-dose antibodies clear plaque dramatically, with manageable side effects. How will the aging brain respond?
“We are learning” was the tenor of debate about the latest round of setbacks for anti-amyloid trials in symptomatic Alzheimer’s disease at a recent conference in Lisbon.
Analyzing Phase 2 trial CSF of an investigational immunotherapy, scientists showed for the first time that treatment mitigates neurotoxic oligomers in patients.
In early Parkinson’s disease, sparse areas on the retina correlate with dying dopaminergic neurons in the substantia nigra.
Neural-wave patterns could help clinicians guide electrodes for deep-brain stimulation.
A batch of new monoclonal antibodies against the C9ORF72 protein also revealed the protein lingers in presynapses.
AAIC showcased advances in scientists’ attempts to integrate technology into dementia care and research. This includes the use of furry robot seals to keep patients company.
PET tracer predicts tau pathology and AD, according to company press release.
Loss-of-function mutations in TBK1 combined with age-related dearth of an analog spell trouble for motor neurons and the central nervous system.
Tau-laden neurons present a phospholipid “eat me” signal, bidding microglia to devour them alive.
Removing senescent cells from mouse brain ameliorates the effects of mutant human tau.
A Wnt pathway inhibitor rescued dendritic spines in cultured neurons and cleared plaques in an AD mouse model.
