Sphere of Influence. In iAssembloids, microglia (red) form projections (white arrows), while astrocytes (green) assume star shapes typically found in the brain. [Courtesy of Kampmann et al., 2025.] ...

The Amyloid—Tangle Connection. Aβ aggregates (green) hyper-excite neurons in tau epicenters and connected regions, strengthening that connectivity. This pushes tau propagation from one region to ...

EBP1 is low in Alzheimer’s disease brains, hinting at human relevance. “Our study suggests that … preservation of functional EBP1 could be a therapeutic strategy for AD,” the authors noted. The ...

Lactylation is a reversible, covalent, post-translational modification of proteins. It happens exclusively on lysine residues, where it influences protein structure, stability, localization, and ...

Could inhaling xenon gas help fight Alzheimer’s disease? In the January 15 Science Translational Medicine, scientists led by Oleg Butovsky at Brigham and Women’s Hospital, Boston, and David Holtzman ...

Missense mutations that derail SORL1 trafficking cause AD. Other variants shift AD risk in East Asians and Europeans. SORL1 dysfunction messes with endosomes in neurons, and with lysosomes in ...

Several types of RNA help regulate gene expression, and a number of these transcripts have been linked to Alzheimer’s disease. However, no one has comprehensively examined how the regulatory RNA ...

Some researchers believe the brain makes Aβ to help fight bacterial and fungal invaders. Now comes evidence that p-tau may take on a similar role against viruses. In the January 2 Cell Reports, ...

For nearly a century, scientists have been trying to understand why many animals live longer, healthier lives when they have less to eat. Now, work led by Sheng-Cai Lin, Chen-Song Zhang, and Xianming ...
