The loss of a key enzyme, called adenosine deaminase, in astrocytes ­­­­— the energy-supporting cells of neurons ­­­­— leads to a toxic accumulation of molecules that contributes to the death of motor neurons seen in amyotrophic lateral sclerosis (ALS), a study shows. The study, “Astrocyte adenosine deaminase loss increases…

SIRION Biotech and Denali Therapeutics have signed a new licensing agreement to develop a new generation of adeno-associated virus (AAV) vectors, harmless viruses used as vehicles to deliver gene therapies, to allow therapies to reach into the central nervous system (CNS) of people  with amyotrophic lateral sclerosis (ALS). The…

An upcoming webinar will focus on the novel approach to clinical trial design in the Modifying Immune Response and Outcomes in ALS (MIROCALS) trial, which aims to break the current impasse in therapy development for amyotrophic lateral sclerosis (ALS). During the webinar, P. Nigel Leigh, a motor neuron disease…

MediciNova’s  investigational therapy ibudilast (MN-166) combined with Rilutek (riluzole), for amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases, has been given final approval — a notice of allowance stating that its request for a patent is being considered by the U.S. Patent and Trademark Office. Receiving a notice of allowance is the final…

Harvard neuroscientists have discovered how the TDP-43 protein — previously linked to sporadic and inherited amyotrophic lateral sclerosis (ALS) cases — reduces the levels of a second player, called stathmin2 (STMN2) — which is necessary for neuron growth and regeneration — making the STMN2 gene a potential new therapeutic target. The study, “…

The rate of weight loss from onset to diagnosis can be a significant indicator of poorer outcomes among amyotrophic lateral sclerosis (ALS) patients, a study reports. The study, “Early weight loss in amyotrophic lateral sclerosis: outcome relevance and clinical correlates in a population-based cohort,” was published in the…

A new method called Axon-seq allows researchers to analyze the content of messenger RNAs (mRNAs) in the motor neuron’s axons, the tips of the nerve cells that communicate with muscle cells, a new study reports. Using Axon-seq, researchers identified 121 mRNAs that are deregulated in ALS motor neurons, highlighting the new…

Researchers have developed a new small molecule that targets the most common genetic defect behind amyotrophic lateral sclerosis (ALS) and frontotemporal dementia, a study reports. These findings suggest that therapies directed at the underlying cause of ALS and frontotemporal dementia may be achievable in the near future. The…

Sativex, a mixture of two active compounds of cannabis, may help control symptoms of spasticity (stiff muscles) in people with amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis, a Phase 2 trial shows. The study “Safety and efficacy of nabiximols on spasticity symptoms in patients with motor…

A new research project that will investigate the seemingly unrelated mechanisms between neurodegenerative diseases and infections has been awarded $2.5 million from the Chan Zuckerberg Initiative (CZI). The funding was awarded to Ivan Marazzi, PhD, assistant professor of microbiology at the Icahn School of Medicine at Mount Sinai in New…
