Résumé

Juvenile dermatomyositis (JDM) is an inflammatory pediatric myopathy characterized by focal capillary loss in muscle, followed by progressive recovery upon adequate treatment with immunomodulating drugs, although some patients remain refractory to treatment. While the underlying mechanism of capillary depletion remains uncertain, recent studies have identified an up-regulation of type I interferon (IFN) expression specific to JDM. Given that myogenic precursor cells (MPCs) exert proangiogenic activity during normal skeletal muscle regeneration, we hypothesized that they may also modulate vascular remodeling/angiogenesis during JDM. The aim of this study was to investigate that hypothesis.
