Together, the Institute of Myology … [Read more]

FOP : une tendance à l’efficacité du palovarotène

Forty people with fibrodysplasia ossificans progressiva (FOP), aged 7 to 53 years, participated in the phase II trial of palovarotene, a selective gamma retinoic acid receptor agonist, versus placebo: 10 received placebo, 9 were treated with 5mg/d palovarotene for 15 days and then 2.5mg/d for one month, and 21 took 10mg/d palovarotene for 15 days and … [Read more]

HDAC6 inhibition improves the phenotype of mdx mice

Laurent Schaeffer’s team in Lyon, in collaboration with a Canadian team in Ottawa, has shown that inhibition of cytoplasmic histone deacetylase 6 (HDAC6) by administration of tubastatin A to mdx mice results in : an improvement in their strength, a decrease in muscle atrophy and fibrosis, an increase in utrophin and beta-dystroglycan levels, inhibition of … [Read more]

The induction of self-tolerance is back on the agenda in myasthenia gravis

According to preclinical work by Spanish researchers, carried out with the help of Rozen Le Panse’s team at the Institute of Myology : intraperitoneal injection of acetylcholine receptors (RACh) encapsulated in liposomes rich in phosphatidylserine decreases the anti-RACh antibody level and improves physical performance (Global clinical score or GCS) in an myasthenia gravis experimental mouse … [Read more]

Beware of cardiac complications in a-7 integrin deficiency

The first mutations in the gene coding for integrin a-7 were described in a very few patients with congenital muscular dystrophy (CMD). An international consortium of researchers has now identified new mutations in this gene, thus adding to the knowledge of the disease, and has also developed an animal model. These new mutations in integrin … [Read more]

Artificial intelligence for the interpretation of muscle biopsy images

Quantifying the number and size of muscle fibres remains a complex, repetitive and time-consuming task. It is hampered, in particular, by the low resolution of biopsy images. French engineers and biologists have developed a new artificial intelligence (AI) tool to try to remedy this. MyoSOTHES is a tool derived from the fusion of two algorithms … [Read more]
