Removing Protein "Garbage" in Nerve Cells May Help Control 2 Neurodegenerative Diseases, Georgetown University Medical Center Study

Neuroscientists at Georgetown University Medical Center say they have new evidence that challenges scientific dogma involving two fatal neurodegenerative diseases — amyotrophic lateral sclerosis (ALS), and frontotemporal dementia (FTD) — and, in the process, have uncovered a possible therapeutic target as a novel strategy to treat both disorders. The study, posted online today in the Journal of Biological Chemistry, found that the issue in both diseases is the inability of the cell's protein garbage disposal system to "pull out" and destroy TDP-43, a powerful, sometimes mutated gene that produces excess amounts of protein inside the nucleus of a nerve cell, or neuron.
