The experimental drug tirasemtiv has shown promise in a phase 2a clinical trial in 32 people with myasthenia gravis (MG). Improvements in general and respiratory muscle function occurred in response to the medication.
Six hours after receiving a single, oral dose of tirasemtiv, study participants showed improvements on a standardized scale of MG severity (the Quantitative MG score) and in forced vital capacity, a measurement of respiratory function.
It’s known that levels of a protein called phosphorylated neurofilament heavy subunit (PNF-H) are increased in the spinal fluid of people with amyotrophic lateral sclerosis (ALS). Now, a team of researchers has demonstrated that higher levels of PNF-H in both the blood and spinal fluid are associated with a faster rate of ALS disease progression and shorter survival time.
Immune system cells known as regulatory T cells— T-regs for short — have been found to play a protective role in mice with a disorder that resembles human amyotrophic lateral sclerosis (ALS). They don't prevent the disease in genetically susceptible mice, but they do appear to slow it down, probably by putting a brake on inflammation in the central nervous system.
Nerve cells called serotonergic neurons degenerate in amyotrophic lateral sclerosis (ALS) and may influence the ALS disease process, an international research team has reported. In particular, the loss of these specialized cells appears to be linked to increased muscle tone or tightness (spasticity).
Results from a completed phase 2 trial of the experimental therapy NP001 in people with amyotrophic lateral sclerosis (ALS) show that in some trial participants, the drug appeared to be effective at slowing or stopping progression of the disease.
Jim received a bachelor’s degree in art from Greenville College (Ill.). He was the art director at Regular Baptist Press in Schaumburg, Ill., prior to his retirement. Although Jim painted for many years, he is no longer able to hold a paintbrush and work on canvases. This piece was drawn using Photoshop CS3 from a photograph of the original barn. He has illustrated many barns and is now drawing houses using the computer.
Don Cleveland, a longtime MDA research grantee studying amyotrophic lateral sclerosis (ALS), has been elected to the Institute of Medicine (IOM). Election to the IOM is one of the highest honors in the fields of health and medicine, and recognizes individuals who have demonstrated outstanding professional achievement and commitment to science.
