In mice with defective PS1 phosphorylation, microglial autophagy falters, exacerbating Aβ burden.
In female mice it’s the other X chromosome, not lack of a Y, that extends life and preserves memory in the face of amyloidosis. A histone demethylase gene partly explains this. It protects people, too.
The first high-resolution look at LRRK2 implies that pathogenic mutations increase binding to microtubules by biasing the kinase domain toward a closed, active conformation.
Three weeks of on-demand seminars to culminate in live Q&A.
The antiviral protein enhances γ-secretase processing of APP. More of it is present in Alzheimer’s disease.
The designer chimera stabilizes synapses in various mouse models of neurodegenerative disease.
In a career spanning four decades, Davies spearheaded the cholinergic hypothesis, unlocked secrets of tau, and readily shared antibodies in the field.
A C9ORF72 polydipeptide repeat induces aggregation by direct interaction with TDP-43, while progranulin mutations that trigger microglial toxicity cause TDP-43 to accumulate via complement.
AMX0035, a mix of sodium phenylbutyrate and taurursodiol, slowed functional decline over six months by about as much as the approved ALS drug edaravone.
Restoring proper gene editing assuaged mitochondrial defects in patient-derived neurons and organoids. Splicing errors may underlie other PD cases as well.
Learning tests may prove more informative in clinical trials of early AD. A new one claims it can spot a difference in six days.
Alector’s AL002c antibody mobilizes microglia, reduces neuronal dystrophy, and restores normal behavior—all in mice. The clinical version is in Phase 1.
In the Alzheimer’s brain, too, plaques trigger a coordinated inflammatory response from microglia and astrocytes. A preprint paper had shown the same for mice.
Three young monkeys missing exon 9 of presenilin 1 seem to have an elevated Aβ42/40 ratio. It remains to be seen if they will develop plaques and tangles as they age.
