Sarepta, Roche and Pfizer will need to solve for the inflammation and fibrosis - BEFORE - Gene Therapy or Exon skipping drugs have any meaningful impact on DMD boys. To intervene with gene therapy once the fibrotic cycle has begun will be largely ineffective: the disease has progressed to the point where the mutation in dystrophin (although the initial trigger) is no longer the driving force of the disease. The radial distance r attains a maximum value of 0.938 when z 1.25. How does a light bulb work This article is about the construction and the working principles of the light bulb, along with the historical back ground of its invention. It may be observed from the pressure bulb that r is zero directly below the point load and increases with the increase in depth below the ground surface. This leads to a vicious cycle in which further loss of muscle function leads to more matrix deposition and eventually to the complete failure of the muscle. The resulting coordinates of r and z are plotted to get the pressure bulb of intensity 0.1Q, as shown in Fig. Several additional theories surfaced at the time of the fire and since. Over a period of years, however, the response to this defect is for accumulation of extracellular matrix around the muscle fibres.Īfter some time, the loss of muscle function is more a result of the presence of this fibrosis than the original mutation in the dystrophin gene. A person who years later claimed that as a boy he found the broken lamp under. Mutations in the dystrophin gene mildly affect the function of skeletal muscle so that shortly after birth the muscle is able to function almost as well as wild-type muscle. Worse still, it may not even prevent further progression of the disease.Ĭonsider a typical monogenic disorder which might be considered for gene therapy in the future such as Duchenne Muscular Dystrophy. It suggests that restoring the wild-type DNA sequence after the disease phenotype has manifested itself will, in most cases, not reverse the phenotype. What are the implications of these observations for the future of gene therapy? She has also joked that Niko is Ness, a combination of Niko and Tess during a livestream and in one of her posts, referencing the infamous Game Theory. This article by Drubaron is a great overview - written in January 2021 when Sarepta announced their terrible progress results for their GT program. Fibrosis is the key, extra dystrophin produced won't help the boys if fibrosis issue is not resolved.
