Endogenous TDP-43 mislocalization in a novel knock-in mouse model reveals DNA repair impairment, inflammation, and neuronal senescence

Abstract excerpt

TDP-43 mislocalization and aggregation are key pathological features of amyotrophic lateral sclerosis (ALS)- and frontotemporal dementia (FTD). However, existing transgenic hTDP-43 WT or ∆NLS-overexpression animal models primarily focus on late-stage TDP-43 proteinopathy. To complement these models and to study the early-stage motor neuron-specific pathology during pre-symptomatic phases of disease progression,...
