Description

While the study shows TDP-43 nuclear egress and that proteinopathy promotes cell death, the specific molecular pathways linking TDP-43 dysfunction to neuronal death after mechanical injury remain unclear. This gap is crucial for understanding ALS/FTD-TBI connections and developing targeted therapies.
