What mechanisms drive TDP-43 pathology specifically in Alzheimer's disease versus ALS/FTLD?

PARTIALLY ADDRESSED

TDP-43 inclusions occur in AD, ALS, and FTLD but the pathogenic mechanisms leading to TDP-43 pathology may differ between diseases. Understanding disease-specific drivers could reveal why TDP-43 shows limbic distribution in AD versus other patterns in ALS/FTLD.
