The first whole-genome manipulation of protein expression in neurons by CRISPR reveals a deadly chain of events. Bad processing by lysosomes leads to build-up of lipids and iron. Oxidative stress revs up. Neurons die by ferroptosis.
African Americans are likelier than non-Hispanic Caucasians to carry low-expression TREM2 variants, and less likely to carry a high-expression variant. As a result, they have less soluble TREM2 in their cerebrospinal fluid.
In early stage trials, light and sound promoted neuronal communication, calmed immune cells, and slowed brain atrophy, but cognitive benefit remains unclear.
The field is shifting from targeting tau’s tips to its mid-region, especially where tau binds microtubules. Several new candidates are in the clinic; whether the strategy will work remains to be seen.
Two mouse models presented at AD/PD may hand scientists more translationally relevant tools to explore LOAD pathophysiology and treatment. The tricks: targeted replacement and knocking in multiple GWAS variants.
At this year’s ICFTD meeting, researchers reviewed the lay of the land of current and planned trials for FTD, with glimpses of how the newly formed FTD Prevention Initiative seeks to coordinate treatment and prevention trials in the future.
