Scientists discover a new molecular pathway shared by two neurodegenerative disorders

Researchers from two independent research teams have discovered how the mislocalization of a protein, known as TDP-43, alters the genetic instructions for UNC13A, providing a possible therapeutic target that could also have implications in treating amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and other forms of dementia. ALS and FTD are two neurodegenerative disorders in which many cases are linked by mislocalization of TDP-43, where instead of being primarily located in the nucleus of the cell where genes are activated, it forms aggregates outside the nucleus in multiple neurodegenerative diseases. Rare mutations in the TDP-43 gene are known to cause ALS, but almost all cases of ALS show mislocalization of TDP-43.
