Prof. Fabrice Chrétien joined the teams of the Institute of Myology on June 15 as Director of the Center for Neuromuscular Exploration and Assessment which is currently composed by a staff of thirty persons. It encompasses three laboratories and a tissue bank: the Neuromuscular Physiology and Evaluation Laboratory, the NMR and Spectroscopy Laboratory, the Morphological Unit and the biological resource centre MYOBANK-AFM.

Prof. Fabrice Chrétien has both a scientific and medical training, more than 20 years of expertise in anatomopathology and 30 years in neuropathology.

His combined clinical and research experience is a valuable asset in leading these various expert and research poles and amplifying their interactions and collaborations to develop common scientific and medical projects within the framework of the Institute’s strategic plan.

At the Institute
Success for AcadeMYO, the first virtual edition of the Myology Summer School AcadeMYO, the first fully virtual release of the institute’s Myology Summer School, took place July 5-9. This 2021 edition was a great success. In fact, 115 people attended the courses including 15 free auditors and 6 representatives of the pharmaceutical industry. Forty-five nationalities were represented among the participants. Read more

DMD: start at I-Motion of trials with pamrevlumab in ambulatory and non-ambulatory patients I-Motion is recruiting patients with Duchenne muscular dystrophy to participate in two pharmacological trials designed to test an antifibrotic monoclonal antibody, pamrevlumab developed by FibroGen.

Our latest news
A single injection of a promising double gene therapy in a OPMD mouse model Promising results for a gene therapy that administers, in a single intramuscular injection, a double sequence that "switches off and replaces" the mutated PABPN1 gene. This product, BB-301, administered to mice models of OPMD, restored muscle weight and strength. Read more

A new form of muscular dystrophy identified using high throughput sequencing There are still many cases of orphan hereditary neuromuscular diseases. This results in diagnostic error that is often harmful to the care of the patient himself/herself, but also to the family (genetic consultation). Read more

Muscle imaging is useful in the diagnosis and follow-up of most autoimmune myositis Idiopathic inflammatory myopathies constitute a heterogeneous group of muscular diseases. Their diagnosis is based, according to recent international recommendations, on muscle biopsy data and specific auto-antibody assays Read more

Clinical and genetic study of 1,000 patients with CIDP reveals 35 cases of misdiagnosed CMT Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) diagnosis is mainly based on the clinical examination and the electromyogram. CIDP is sometimes confused with another demyelinating neuropathy, type 1 Charcot-Marie-Tooth disease. Read more

High phenotypic diversity in patients with CMT linked to a mutation in the MPZ gene? Hereditary sensory-motor neuropathies type Charcot-Marie-Tooth (or CMT) are clinically and genetically heterogeneous pathologies. Almost 110 genes, inherited on autosomal dominant or recessive or X-linked dominant mode, are responsible, whether they are demyelinating forms (CMT1) or axonal forms (CMT2). Read more

More breaking news
A good record for the longest follow-up to date of Zolgensma in SMA After obtaining positive results on the motor development of 15 infants with type I SMA, aged less than 6 months and symptomatic during the first gene therapy trial lasting two years (START study), Zolgensma (onasemnogene abeparvovec) will be evaluated over the next 15 years (START long-term follow-up study). Read more

Systemic injection of an optimized antisense oligonucleotide into an FSH mouse model appears to be effective In FSH, the DUX4 gene is abnormally expressed in the muscles. In an effort to inhibit DUX4, Canadian researchers have optimized antisense oligonucleotides by coupling them to a peptide that favors their penetration into muscle cells. Read more
