TL;DR

Combined multi-omic profiling of synaptosomes enriched from postmortem frontal cortex and patient-derived induced pluripotent stem cell (iPSC)-derived cortical neurons defines convergent molecular pathways underlying synapse vulnerability in both C9-FTD model systems and identifies synaptic localization of CE-containing transcripts as a previously unrecognized feature of TDP-43 proteinopathy.

Breakdown in the synaptic vesicle cycle defines early and reversible cortical pathogenesis in ALS

Synaptic failure is considered an early driver of Amyotrophic Lateral Sclerosis (ALS), yet identifying the molecular events initiating synaptic decline remains challenging in end-stage human tissue. Here, we exploit the late involvement of the primary visual cortex (Brodmann Area 17 (BA17)) to investigate early disease...
