Brief Summary:
Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder characterized by progressive muscle weakness and eventual death. Studies demonstrate that the immune system plays a key role in ALS progression; however, the role of the immune system is unclear, as various aspects can play both a beneficial and detrimental role in the disease course. Attempts to universally suppress the immune system in ALS patients have at best had negligible effects on progression or at worst accelerated the disease. Thus, there is a critical need to identify immune cell populations to serve as biomarkers and therapeutic targets.
