by National Institutes of Health Credit: Neuron (2023). DOI: 10.1016/j.neuron.2023.01.007 New research offers clues about the biology of cells in the spinal cord that die off in amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases. A team of researchers supported by the National Institutes of Health has found evidence linking motor neurons’ large cell size and supporting...
by Bruno Geoffroy, University of Montreal Hospital Research Centre Neuroprotection mechanism of Lacticaseibacillus rhamnosus HA-114. ALS models have impaired carnitine shuttle, a mechanism to transport long chain fatty acids across the mitochondrial membrane for energy production via β-oxidation. Fatty acids, supplied by the probiotic bacteria, is believed to enter the mitochondria independently of the carnitine...

That’s the finding of a...
by Amy Norton HealthDay Reporter Researchers have made early progress toward a new approach to treating the deadly brain disease amyotrophic lateral sclerosis (ALS): using patients’ own immune system T cells. ALS is a rare condition that kills nerve cells in the brain and spinal cord that control movement. Over time, it robs people of their ability to...

Credit: Paul Alan Cox Patients with ALS, one of the most serious neurological diseases known, have been hampered by the time it takes to receive an accurate diagnosis. The period between the onset of symptoms and...

by University of Illinois at Chicago Figure 1. SOD1G93A mice have slow intestinal mobility, decreased rotarod test time and grip strength during ALS progression. (a) SOD1G93A mice significantly increased gut transit time starting at 2-month-old compared to WT mice. In age-matched WT and SOD1G93A mice, intestinal mobility was tested using Evans blue marker (5% Evans blue, 5% gum...
JANUARY 24, 2022 by National Institutes of Health Credit: Pixabay/CC0 Public Domain Using an experimental drug, researchers have been able to suppress a mutated amyotrophic lateral sclerosis (ALS) gene. Studies in mice demonstrate that the therapy could show promise in treating rare, aggressive forms of ALS caused by mutations in the fused in sarcoma (FUS) gene....
by Mayo Clinic Using samples donated to Mayo Clinic’s Brain Bank for Neurodegenerative Disorders, as well as mouse models, biochemistry, confocal microscopy, and computational simulations, researchers showed that a receptor on microglial cells, called TREM2, can clear a protein that builds up in the brains of patients with ALS.
