RNA-targeting CRISPR System Shows Promise in Preclinical Models

A CRISPR-based gene editing system could be used to reduce the activity of genes associated with amyotrophic lateral sclerosis (ALS) and Huntington’s disease, a new study shows. The study, “Targeted gene silencing in the nervous system with CRISPR-Cas13,” was published in Science Advances. CRISPR is a strategy that…

#MDA2022 – CNM-Au8 May Slow Progression, Reduce Risk of Death

Treatment with Clene Nanomedicine’s experimental medicine CNM-Au8 may decrease the risk of disease progression or death in people with early amyotrophic lateral sclerosis (ALS), according to new analyses from the RESCUE-ALS clinical trial. Data also suggest that the therapy helped to prevent the loss of motor neurons in…

BMAA, Formaldehyde Among Toxins in Environment Linked to ALS Risk

Exposure to certain toxic compounds — including beta-N-methylamino-L-alanine (BMAA), formaldehyde, and heavy metals like manganese, mercury, and zinc — increases the likelihood of developing amyotrophic lateral sclerosis (ALS), according to a review paper. Its authors argue that with BMAA — a toxic compound made by algae — enough evidence…

London-based CERF Prizes Benefit U.S.-based Research

The Cullen Education and Research Fund (CERF), a private philanthropy based in London, has awarded more than $800,000 to support two U.S. research projects that are working to improve life for people with amyotrophic lateral sclerosis (ALS). The CERF Medical Engineering Prize, worth €500,000 (about $570,000), was awarded to…

Structure of TDP-43 Protein Clumps Identified for First Time

A team of scientists in the U.K. and Japan has determined the structure of aggregated TDP-43, the protein whose abnormal clumps are characteristic of amyotrophic lateral sclerosis (ALS). Their work, reportedly the first to reveal the molecular structure of aggregated TDP-43, identified a “double-spiral fold” of the protein in patients’ brain…
