Mitochondrial abnormalities seen early in many forms of ALS: Study

A study found that genetic mutations associated with amyotrophic lateral sclerosis (ALS) lead to problems with the function and transport of mitochondria, cellular structures needed for energy production, early in the disease course, before abnormal protein clumps are formed. “We show that the nerve cells, termed motor neurons, that…

Adding low-dose IL-2 to riluzole may improve survival in ALS

Adding a low dose of the anti-inflammatory molecule interleukin-2 (IL-2) to treatment with riluzole is safe and may help extend survival in certain people with amyotrophic lateral sclerosis (ALS), according to findings from a clinical trial called MIROCALS. The Phase 2b trial didn’t show a significant survival benefit in…

Treatment with Tregs safe, may slow ALS progression: Trial

Treatment with regulatory T-cells, or Tregs — a type of anti-inflammatory immune cell — was well tolerated and seemed to slow disease progression in a small clinical trial that enrolled six people with amyotrophic lateral sclerosis (ALS). The work was conducted by scientists at Columbia University in New…

3-drug combo shows promise for treating SOD1-ALS: Mouse study

A combination of three drugs — one of them the experimental therapy CuATSM — may be effective for treating amyotrophic lateral sclerosis (ALS) caused by mutations in the SOD1 gene, according to a new preclinical study. In mice carrying SOD1 mutations, the combination of these three drugs — CuATSM,…

Using NfL biomarker could improve ALS diagnosis, prognosis: Study

Measuring blood levels of neurofilament light chain, or NfL, a biomarker of nerve damage, may help in diagnosing amyotrophic lateral sclerosis (ALS), and in predicting the risk of death among people with the neurodegenerative condition, a new study shows. This biomarker showed substantially better accuracy for both ALS diagnosis…
