DAY 5 – Focus on the heart and advanced therapies
The congress Myology 2016, organised by AFM-Téléthon, is now coming to an end: over 900 international experts in the field (researchers, clinicians, doctors…) have compared their latest work for 5 days. This edition was undoubtedly marked by the beginning of the therapeutic era for neuromuscular diseases with the presentation of clinical trials results in human and the first lessons learnt from those trials.
Now again, we’ve witnessed presentations on the advances and the projects of gene and cell therapies for the heart, whether for cardiomyopathies or post-infarction heart failure. Therefore, P. Menasché (HEGP, Paris), leading the 1st French trial using embryonic stem cells for heart attack victims, spoke up. Drawing on his experience (4 patients now treated), he outlined the future development of this cell therapy approach, underlining the importance of trophic factors brought by the transplanted cells over the cells themselves. Lucie Carrier from Hamburg presented her work on mice for a gene therapy of genetic cardiomyopathy. For her part, Hélène Puccio (Illkirch) showed that gene therapy of cardiomyopathy in Friedreich’s ataxia works for mice, even in post-symptomatic cases. The vector used (AAV10-FXN) is being developed by the company Anapurna for a trial in human.
This 5th edition of the AFM-Téléthon congress was also the occasion for the young researchers financed by the Association to show their works to the international scientific community. Two of them received a prize for their oral presentation: Muriel Sébastien (Institute of neurosciences, Grenoble) and Pierre Klein (Institute of Myology, Paris).

DAY 2 - Muscle biology and neuromuscular junction
Throughout this second day, Myology 2016 was the stage of plenary sessions focused on “Fundamental muscle biology and neuromuscular junction.”
This second day started with a lecture by Christophe Marcelle, initially in charge of the Australian Regenerative Medicine Institute at the University Monash in Melbourne, which has carried out the project Muscle formation, growth and repair since 2009. This project allows the understanding of cellular and molecular mechanisms, which regulates differentiation and myogenic repair. He is now carrying out this project among NeuroMyoGène, a new institute based in Lyon and whose goal is to establish a centre of excellence on neuromuscular diseases in the Auvergne-Rhône-Alpes area. During his speech, he especially discussed how the future of the embryo cells can be influenced by various factors. These results emphasise a link between myogenesis and a change in cell adhesion in numerous developmental and disease processes.
The following subjects were also mentioned throughout the day: mitochondrial dysfunctions, the functioning of neuromuscular junctions and the mechanism of some diseases, notably myasthenia (an autoimmune neuromuscular disease) or metabolic diseases.
During the symposium called Metabolic Diseases, the muscle lipidic metabolism disorders were presented by Pascal Laforêt (Assistance Publique – Hôpitaux de Paris) from the Institute of Myology (Paris). These disorders are inborn errors of metabolism, which manifest themselves in adults as a progressive muscular weakness of the limbs or exercise intolerance with rigidity or induced muscular pain, often coming along with regular episodes of rhabdomyolysis (risk of acute renal failure). Even if they are rare, those diseases are now more and more known because of the increasing use of tandem mass spectrometry enabling to detect the accumulation of acylcarnitines in blood. The diagnosis is essential because some of these rare diseases can be treated or improved by a dietary plan or drugs.
In type 2 glycogenesis, Pr. Ven der Ploeg (Netherlands) reviewed 18 years of enzyme replacement therapy for children and adults (over 700 patients treated in the world), generally involving a stabilisation for adults and an improved efficiency for children. The first child treated in 1999 is going to celebrate his 18th birthday, while this disease is fatal for newborns.

DAY 1 - 30 years after the discovery of gene involved in Duchenne muscular dystrophy, myology has become the backbone of therapeutic innovation
“The identification of the gene involved in Duchenne muscular dystrophy was a split in the history of human genetics. It marked the beginning of very numerous gene identifications. Over 5,500 are now identified, including 150 for neuromuscular diseases.”
“30 years ago, 400 researchers went to the symposium in Tours and it was a great success for our Association. Here in Lyon, in 2016, you are over 800 to exchange and discuss for 5 days. The international community of Myology has been extended, strengthened… it is the backbone of therapeutic innovation. Most of the communications of Myology 2016 will focus on innovative therapeutic pathways, on ongoing clinical trials involving hundreds of patients around the world, and even on the first drugs on their way to be authorised on the market. We have undoubtedly entered a new era! And the closer we get to our goal – Cure – the more complex and numerous are the challenges : treating the whole body, bioproduction of the advanced therapies at an industrial scale, obtaining the first authorisation of marketing for those advanced therapies… We are opening the way in numerous fields and the years to come will be decisive.” declared Laurence Tiennot-Herment, president of AFM-Téléthon, during the opening of Myology 2016.
