Endomysial Fibrosis, Muscular Inflammatory Response and Calcium Homeostasis Dysfunction in Duchenne Muscular Dystrophy

key information

study id #: NCT01823783

condition: Duchenne Muscular Distrophy (DMD)

status: recruiting


Duchenne muscular dystrophy (DMD) is the most common and devastating form of muscular dystrophy, caused by an X-chromosome gene mutation resulting in the absence of the protein dystrophin. Gene therapy by exon skipping or stop codon read-through and cell therapy are at the stage of clinical assays with very promising results. Nevertheless, they will not allow a complete cure of DMD patients and they will concern only specific types of mutations. It is therefore crucial to develop other therapeutic strategies related to the natural history of the disease and targeted not on the dystrophin itself, but on the consequences of its absence. Another crucial pathophysiological pathway in DMD is muscle cell calcium homeostasis, particularly via the ryanodine recepteur (RyR1). Our study focus on the relationship between endomysial fibrosis, abnormal inflammation response and calcium homeostasis dysfunction which are not entirely established in DMD. The identification of the biological mechanisms that play a role in the severity of the phenotype, particularly endomysial fibrosis, should allow the development of targeted pharmacotherapy as a complementary strategy for the future treatment of DMD.
