Clusters containing a protein called LAT use specific adapters to move and drive the activation of T-cells to fight off infection, according to a study, the findings of which may help design immune cells with more selective effects, the researchers suggest. The study, “A composition-dependent molecular clutch…

People with amyotrophic lateral sclerosis (ALS) have an altered composition of their gut microbial community, with an increase in harmful microbes and a decrease in beneficial microorganisms, according to a new small study. This altered gut microbiota could drive digestive problems in those with ALS, the researchers said. The…

Cognitive problems have limited impact on overall health-related quality of life (QoL) in people with amyotrophic lateral sclerosis (ALS) — but verbal fluency and space orientation are among the factors linked to patients’ emotional well-being, according to new research. The study, “Cognitive deficits have only…

Concerns over an active pharmaceutical ingredient used in a 2017 study of Nurtec (riluzole) as a bioequivalent medicine were voiced by the U.S. Food and Drug Administration (FDA) in its response to a request for the treatment’s approval for  amyotrophic lateral sclerosis (ALS), its developer, Biohaven Pharmaceuticals,…

Men with benign prostatic hyperplasia (BPH) — prostate gland enlargement — are not at greater risk of amyotrophic lateral sclerosis (ALS) and similar disorders, according to a nationwide study in Denmark. “We found no evidence of an increased risk of ALS and other MND [motor neuron diseases] among…

Differences in how efficiently nerve cells degrade and discard proteins may explain why some motor neurons better resist a buildup of toxic proteins than do others in people with amyotrophic lateral sclerosis (ALS), according to a study in mice. The study, “Stem cell-derived cranial and spinal motor…

Scientist Manish Arora, PhD, received an $8 million Outstanding Investigator Award from the National Institute of Environmental Health Sciences (NIEHS) to develop models to predict and possibly prevent diseases such as amyotrophic lateral sclerosis (ALS). Arora and his team developed the Biodynamic Interface, which proposes an interplay…

Although people who develop amyotrophic lateral sclerosis (ALS) have altered levels of several blood metabolites — products of our cells’ metabolism — before disease onset, these changes do not enable reliable identification of who is at risk of having ALS, according to a large study. The research, “…

Only a minority of amyotrophic lateral sclerosis (ALS) patients are concerned about a possible negative impact of genetic testing on their well-being and that of their family, according to the results of a small survey in the Chicago area. The survey’s findings, presented in a poster session at the…

A vitamin D activator molecule known as CYP27B1 is a biomarker of muscle alterations in patients with amytrophic lateral sclerosis (ALS) and may be a marker of clinical progression of the disease, according to new research. The findings, “The Vitamin D Activator, CYP27B1, is a Novel…
