Quantifying 95 post-translational modifications of tau extracted from AD and control brains, a proteomics study proposes a “processive” model of phosphorylation, ubiquitination, acetylation that drive aggregation and map to distinct stages of disease.
Harvard or MIT? The microbiomes of mice raised in different facilities dictated their response to C9 deficiency, including whether they died young. Do gut microbes influence ALS?
Built to cross the blood-brain barrier, the vehicle delivers therapeutic antibodies, enzymes, and potentially small molecules such as oligonucleotides.
Many Alzheimer’s trials had minimal dosing interruptions, but recruitment stopped for a time. Others trials fared worse, with some scrapped altogether. One administered study drug in an ambulance.
Tissue from 13-week-old fetuses carrying the huntingtin repeat expansion shows defects in neuronal polarity and proliferation, which lead to fewer neurons populating some brain regions.
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 R1279Q variant of angiotensin-converting enzyme associates with AD and causes neurodegeneration in mice. In a model of amyloidosis, it accelerates decline.
