Newsletter #92 – January 2023

Dear patients and their families,
Dear donors,
Dear partners,

All the teams and collaborators of the Institute of Myology send you their best wishes for happiness and success and wish you excellent health. May this new year, full of promise, be synonymous with progress and success and enable us to accomplish the projects we cherish.

We would like to extend our heartfelt thanks to all the generous donors who supported us in 2022, despite an environment that remains challenging. Your continued support and renewed trust are essentiel for the research and care activities conducted by our Institute’s laboratories and departments. Each of your donations enables us to move forward in our research and scientific and medical advances in favour of rare diseases. We all share the same conviction: Further progress in the knowledge of muscle for a better health for all!

Each day, by pushing the limits of knowledge, our researchers are exploring new ways to better understand muscle and develop new diagnostic and therapeutic solutions to combat neuromuscular disease.

As we are well aware, each study, research and clinical trial requires a long-term commitment and appropriate means: The medical progress of tomorrow depends on the research of today. It is therefore vital to pursue our efforts!

Together, we form a united and committed team to achieve our Ambition Myology Foundation and give new momentum to the study of Muscle, a public health challenge.

When it comes to fighting disease, every action matters. Thank you for your unwavering understanding and everything you do for us and most importantly WITH US!

Crossed views on the evaluation and expected benefits of the use of exoskeletons D. Bachasson and G. Bassez present here a key research project conducted at the Institute on the evaluation of the conditions and expected gains from the use of exoskeletons in two ongoing clinical trials. F. Chrétien details the challenges of NIC, a unique platform where evaluation is at the interface of research and patient care. Read more

A review of the year 2022 with the AFM-Téléthon The year 2022 has just drawn to a close, carried by the slogan “We will not give up”, which has enabled AFM-Telethon to celebrate its greatest victories and to continue the fight for all those whose disease remains untreated. 2022 also saw new advances in research in several diseases, the organization of a major international scientific congress, and was also marked by demands for caregivers and access to innovative treatments.

Our latest news
Cytoskeletal involvement in dilated cardiomyopathy caused by LMNA gene mutations Interview with Caroline Le Dour, post-doctoral fellow in the Signaling Pathways & Striated Muscles team (MCR) who just published an article in Nature Communications focusing on the interaction of actin and microtubule cytoskeletons in cardiomyopathy caused by LMNA gene mutations.

SAPPHIRE trial starts at I-Motion The SAPPHIRE trial is an international, randomised, double-blind, placebo-controlled phase III trial that will evaluate the effects of a treatment that targets the muscle, apitegromab, used in addition to another treatment that acts on the production of NMS, nusinersen or risdiplam.

Innovative non-amplification targeted long-read sequencing method enables more accurate characterization of CTG repeats in DM1 patients The REDs team at the Myology Institute developed a long-read sequencing method without amplification using CRISPR/Cas9 technology in DM1. Read more

Myasthenia gravis: the role of thymic macrophages is essential In this French study, the authors, among whom were researchers at the Institute of Myology, investigated whether AChR-MG is characterised by an IFN-I signature in the blood; they also studied the chronic thymic IFN-I signature. Read more

Anti-fibrotic drug therapies in skeletal muscle diseases Fibrosis is defined as an excessive accumulation of extracellular matrix. It can affect many organs, including muscles. It is the result of a defective regeneration process, unresolved inflammation or chronic damage. Read more

Electrophysiological studies are useful in differentiating CMS Researchers from the Institute of Myology analysed electroneuromyography data from 120 patients with congenital myasthenic syndromes (CMS) and compared them with the results of genetic studies. Read more

Miniaturised “organ-on-chip” for muscle dystrophy modelling Quantifying functional contraction of skeletal muscle is essential to assess the outcome of therapies in neuromuscular diseases. A team of scientists including researchers from the Institute of Myology has developed a miniaturised three-dimensional myotube culture chip which can monitor contraction at a single cell level. Read more

Dosing for IgG and especially IgG2 anti-TIF1γ in adult dermatomyositis would refine cancer risk assessment Anti-transcription intermediary factor 1 γ (TIF1γ) autoantibodies are associated, in adults with dermatomyositis, with an excess risk of cancer. A French study involving clinicians from the Institute of Myology had shown in 2019 that anti-TIF1γ of IgG2 subtype could be a biomarker of this tumor risk. A result confirmed by a retrospective international study conducted under the aegis of the European NeuroMuscular Center in 132 adults with dermatomyositis with anti-TIF1γ Read more
