Fish Model of ALS Links TDP-43 Protein Clumping to Motor Neuron Ills

A zebrafish model that reproduces key amyotrophic lateral sclerosis (ALS) symptoms and characteristics, including protein clumping, when exposed to blue light could aid in understanding disease mechanisms and in developing new treatments. The model was described in the study, “Optogenetic modulation of TDP-43 oligomerization accelerates ALS-related…

Beginning on Feb. 29, Rare Disease Day, chapters from notable scientific books and clinical review articles covering rare disorders will be available free-of-charge from Elsevier. The offer runs through April 30, and aims to supports work by researchers and clinicians into a better understanding of and treatments for rare diseases, as well…

Oh, how I wish living with ALS weren’t so murky: We don’t know its cause, we don’t have a cure, and we measure symptom progression by way of 12 questions. I can’t do anything about the cause or cure, but I’m up on my soapbox (the one with the…

The Medidata Institute and Project ALS have announced a research partnership aimed at better understanding amyotrophic lateral sclerosis (ALS) and developing new and personalized treatment approaches. With a focus on rare diseases, the institute works with scientists, regulatory agencies, patient advocates, life science companies, and research…

Astrocytes — cells of the nervous system cell that provide support to neurons — were seen to help protect motor neurons from damage caused by toxic protein clumps in a cell model of amyotrophic lateral sclerosis (ALS). The study reporting this finding, “Distinct responses of neurons…

Factors like head trauma or fracture, electric shock, playing some competitive sports, drinking water from private wells, use of herbicides for gardening, and taking specific dietary supplements all may be associated with the development of amyotrophic lateral sclerosis (ALS), according to a new study. However, larger studies are required…

I didn’t react when a spine care specialist mentioned ALS as a possible cause of my husband’s weak arm, because I didn’t know what ALS was. Todd and I talked about daily life during the drive home from the appointment, and it wasn’t until later that evening when the kids…

A neurotoxic amino acid called β-N-methylamino-L-alanine (BMAA) fed to vervet monkeys caused damage to the spinal cord similar to what is seen in amyotrophic lateral sclerosis (ALS), potentially making them a much-needed new animal model for research, a study reported. Adding L-serine, a non-toxic amino acid, to their diet…

Starting a 501(c)(3) tax-exempt nonprofit isn’t easy, but the National Organization for Rare Disorders gave a few tips for those  looking to begin the complex process in its Feb. 20 webinar.  William Whitman…

“I don’t want to belong to any club that would have me as a member.” That sentiment, expressed by comedian Groucho Marx in 1949 about his affiliation with a particular social organization, was exactly my reaction in learning of…
