Resumo

The expression and function of integrin-type extracellular matrix receptors, VLA-4 and VLA-5, and laminin receptor VLA-6 on the surface of CD3(+)CD4(+) and CD3(+)CD8(+) defined T cell populations was evaluated in the blood of Duchenne muscular dystrophy (DMD) patients and healthy individuals. Both the number of CD4(+) and CD8(+) T cell subsets expressing VLA-4 or VLA-5 and the fibronectin-driven T cell migration was significantly higher in DMD patients. These data indicate that interactions of VLA-4 and/or VLA-5 with fibronectin may drive T lymphocytes to specific niches within muscle, contributing to tissue damage and fibrosis in DMD patients.
