Exosome Derived from Mesenchymal Stem Cells Alleviates Pathological Scars by Inhibiting the Proliferation, Migration and Protein Expression of Fibroblasts via Delivering miR-138-5p to Target SIRT1
More than thirty years after discovering Leber’s hereditary optic neuropathy (LHON) as the first maternally inherited disease associated with homoplasmic mtDNA mutations, we still struggle to achieve effective therapies. LHON is characterized by selective degeneration of retinal ganglion cells (RGCs) and is the most frequent mitochondrial disease, which leads to blindness young people, in particular males. Despite the causative mutations are present in all tissues, yet only a specific cell type is affected. Our deep understanding of the pathogenic mechanisms in LHON is hampered by the lack o...
