Current gene therapy approaches aim to restore a shortened form of dystrophin (microdystrophin) via adeno-associated vector delivery. While recent clinical studies show promise, therapeutic efficacy remains incomplete, emphasizing the need for improved approaches. Here, we identified lysosomal perturbations in myofibers of patients with DMD and animal models, an overlooked mechanism of cellular damage in muscular dystrophies. These were notably marked by the up-regulation and recruitment of Galectin-3, a biomarker of lysosomal membrane permeabilization, to lysosomes, alongside alterations in lysosome number, morphology, and function. Microdystrophin therapy in\n                    <jats:italic toggle=\"yes\">\n                      Dmd\n                      <jats:sup>mdx<\/jats:sup>\n                    <\/jats:italic>\n                    mice fails to fully correct these damages. However, combining it with trehalose, a lysosome-protective disaccharide, substantially improves the outcome, enhancing muscle function, myopathology, and transcriptome. These findings highlight lysosomal damage as an important pathomechanism in DMD and suggest that combining trehalose with gene therapy could enhance therapeutic efficacy.\n                  <\/jats:p>","DOI":"10.1126\/sciadv.adv6805","type":"journal-article","created":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T17:59:42Z","timestamp":1761155982000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":12,"title":["Lysosomal damage is a therapeutic target in Duchenne muscular dystrophy"],"prefix":"10.1126","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-5015-9911","authenticated-orcid":true,"given":"Abbass","family":"Jaber","sequence":"first","affiliation":[{"name":"G\u00e9n\u00e9thon, 91000 Evry, France."},{"name":"Universit\u00e9 Paris-Saclay, Univ.
