MDA Hosting Online Q&A on COVID-19 Today

The Muscular Dystrophy Association (MDA) is hosting an online Q&A session today to discuss the best ways that people with neuromuscular diseases might protect themselves during the COVID-19 pandemic. The 30-minute session can be accessed on the MDA’s Facebook page, and starts at 6 p.m. EST. People with…

Stimulating Muscle Cells May Help to Repair Motor Neurons

Muscle cell activity helps to promote motor nerve cell repair after injury, scientists found in using a device to model motor neuron and muscle cell interaction. They believe this finding could be relevant to diseases like amyotrophic lateral sclerosis (ALS) that imperil motor neuron survival. The device was described…

Study Finds Differences in Cerebrospinal Fluid Dynamics in ALS

There are differences in the way the fluid around the brain and spinal cord moves in people with amyotrophic lateral sclerosis (ALS), and understanding these could have implications for the development of future therapies, a study suggests. The study, “Non-invasive MRI quantification of cerebrospinal fluid dynamics…

Fish Model of ALS Links TDP-43 Protein Clumping to Motor Neuron Ills

A zebrafish model that reproduces key amyotrophic lateral sclerosis (ALS) symptoms and characteristics, including protein clumping, when exposed to blue light could aid in understanding disease mechanisms and in developing new treatments. The model was described in the study, “Optogenetic modulation of TDP-43 oligomerization accelerates ALS-related…
