Chronic inflammation in DMD exacerbates the complications associated with disease progression. Since the lymphatic system plays a crucial role in regulating and resolving inflammation, our primary goal was to investigate whether lymphatics were dysregulated in skeletal muscle of DMD animals. We used the\n                    <jats:italic toggle=\"yes\">D2.mdx<\/jats:italic>\n                    murine and golden retriever muscular dystrophy (GRMD) canine models, as well as mouse and rat lymphatic muscle cells (LMCs) to determine the role of dystrophin in lymphatic structure and function in skeletal muscles. Single-cell RNA sequencing data from control LMCs showed dystrophin expression, and protein results demonstrated that the 427-, 140-, and 71-kDa dystrophin isoforms were detectable in the LMCs from control mice, whereas the 427 kDa isoform was undetectable in LMCs derived from\n                    <jats:italic toggle=\"yes\">D2.mdx<\/jats:italic>\n                    mice.

The gene expression profile and immunofluorescence analyses of dystrophic muscle revealed inflammatory lymphangiogenesis in dystrophic muscle. Skeletal muscle tissues that showed improvement in function after adeno-associated virus-microdystrophin treatment also showed significant improvement in inflammatory lymphangiogenesis in GRMD dogs. Thus, these results show a linkage between lymphatic function and DMD pathogenesis that merits further investigation in DMD patients.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2505656122","type":"journal-article","created":{"date-parts":[[2025,9,18]],"date-time":"2025-09-18T17:53:16Z","timestamp":1758217996000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":0,"title":["Lymphatic dysfunction is linked to disease pathogenesis in Duchenne muscular dystrophy animal models"],"prefix":"10.1073","volume":"122","author":[{"given":"Bhuvaneshwaran","family":"Subramanian","sequence":"first","affiliation":[{"name":"Department of Medical Physiology, Naresh K.
