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 weeks of on-demand seminars to culminate in live Q&A.
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.
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.
Restoring proper gene editing assuaged mitochondrial defects in patient-derived neurons and organoids. Splicing errors may underlie other PD cases as well.
The antiviral protein enhances γ-secretase processing of APP. More of it is present in Alzheimer’s disease.
Learning tests may prove more informative in clinical trials of early AD. A new one claims it can spot a difference in six days.
Comprising mostly Aβ40, these large plaques are shot through with strange tubular structures and BBB markers. They are common in early onset AD.
In a career spanning four decades, Davies spearheaded the cholinergic hypothesis, unlocked secrets of tau, and readily shared antibodies in the field.
Three studies agree that TMEM106b/progranulin double knockouts develop more extreme lysosomal dysfunction, inflammation, and motor deficits than PGRN KOs.
Homozygous carriers of GM17—a common IgG1 variant the HSV-1 virus has evolved to evade—had quadruple the risk of developing AD. In a small Swedish cohort, that is.
The day-long advisory committee meeting will be broadcast live online. Prerecorded presentations are to be available November 4; the public can submit comments.
A recent genetics symposium drew positive reviews for its approach of following up prerecorded, on-demand talks with a live Q&A session.
A panel of experts concludes the evidence for this scary prospect is weak, but recommends neurosurgeons use separate neurosurgical instruments for young and old patients. The experts called for further studies.
