Scientific and Technological Prospecting on Polymeric Particles Containing Extracellular Matrix Peptides for the Treatment of Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy is a neuromuscular disease with an overall incidence of between 1 in 5,000 newborn males. Carriers may manifest progressive muscle weakness, resulting from the progressive degeneration of skeletal muscles, generating cardiac and respiratory disorders. Considering the lack of effective treatments, different therapeutic approaches have been developed, such as protein synthesis and extracellular matrix derivatives that can be used to improve muscle regeneration, maintenance, or repair. At the same time, the use of other anti-inflammatory drugs or biological agents to replace corticosteroids conjugated to these extracellular matrix derivatives may act more effectively in controlling the progression of Duchenne muscular dystrophy. Extracellular matrix-derived peptides (e.g. laminin-111 derivatives) and the use of essential oils with antiinflammatory activity in polymeric particles for application in the treatment of Duchenne muscular dystrophy are discussed. For this purpose, the literature of patents and scientific articles from 2012- 2024 on LM-111 peptides and Duchenne muscular dystrophy was reviewed. Many patents focus on palliative technologies that seek to prolong the progressive effects of the disease, considering the control of the inflammatory process. The technological and scientific prospecting suggests the need for continuous research on systems that can serve as a treatment for Dystrophy.
