For each structural strain of tau fibrils, they identified amino acids without which the strain cannot form its signature ...

The X contains more genes related to brain function than does any other chromosome. “The X chromosome may be a treasure trove of genes that influence cognition, and these could be therapeutic targets, ...

The Senescence Accelerated Mouse-Prone 8 (SAMP8) is a naturally occuring mouse line that displays a phenotype of accelerated aging. While maintaining an inbred AKR/J line in the early 1970's, ...

This transgenic model of tauopathy expresses MAPT with the P301S mutation, which is associated with autosomal-dominant disease in humans. The hTau.P301S model recapitulates several molecular, cellular ...

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

SORL1 dysfunction messes with endosomes in neurons, and with lysosomes in microglia.

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.] ...

Stop the Spread. Injecting saline into mouse kidneys did not affect the left or right substantia nigra (top). Injecting fibrils of α-synuclein ablated about half of the dopaminergic neurons (middle ...

I have no competing interest.

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 ...
