Scientists report at AAT-AD/PD that they tightened a causal connection between gut microbes, microglial function, and protein deposits. In mice, that is.
In a Phase 2 trial, the vaccine reportedly normalized the rise in plasma NfL, and appeared to lower CSF tau and retard brain atrophy.
Massive meta-analysis finds the longevity gene’s VS haplotype staves off mild cognitive impairment and AD. It reduces amyloid burden.
At Tau2020 conference, scientists implicate LDL receptor-related protein 1 in cell-to-cell transmission.
In people with Alzheimer’s biomarkers, the basal forebrain shrinks early, foreshadowing microglial neurotoxicity, atrophy in the medial temporal lobe, and cognitive decline.
In a mouse model of amyloidosis, human wild-type TREM2 kept Aβ deposition at bay early on, but this defense became overwhelmed as plaques grew. The R47H AD risk variant never offered protection early on, and made things worse later.
Researchers at the online AAT-AD/PD meeting touted therapies that target neuroinflammation, synapses, epigenetic regulation, or the cortisol stress response.
For people with Parkinson’s, carrying Alzheimer’s genetic risk variants upped their odds of harboring Aβ and tau pathology and getting dementia. In people with DLB, Aβ plaques worsened tau and Lewy pathology, and cognition.
In nonhuman primates, three classes of LRRK2 kinase inhibitor cause microscopic changes in lung morphology, but they are reversible and do not impair breathing. Parkinson’s programs remain on track.
For several neurodegenerative diseases, scientists identified which cell types exert a person’s inherited risk. In Alzheimer’s, it’s microglia; in Parkinson’s, it’s dopaminergic and enteric neurons—and oligodendrocytes.
Avid’s postmortem validation data indicate Alzheimer’s can be diagnosed by visual examination of flortaucipir PET scans.
Award recognizes discoveries of genetic variants that perturb liquid-liquid phase separation and increase risk for ALS-FTD and other neurodegenerative diseases.
Trialists are shooting new arrows at the disease, including compounds that tweak autophagy, neuroinflammation, and glycolipid recycling.
Loss-of-function variants in the demethylase TET2 raise a person’s risk for early and late-onset Alzheimer’s, as well as FTD and ALS, suggesting a common mechanism.
Hippocampal imaging and fluid markers of BBB damage found in ApoE4 carriers.
