Modulation of retroviral capsid assembly halts ARC-mediated TDP-43 intercellular spreading

Intercellular propagation of pathological TDP-43 drives the progression of ALS and FTD, yet the mechanisms enabling transmission remain elusive.

Intercellular propagation of pathological TDP-43 drives the progression of ALS and FTD, yet the mechanisms enabling transmission remain elusive. Here, we demonstrate that Activity-regulated cytoskeleton associated protein (ARC/Arg3.1) is pathologically subverted to act as a…
