Lymphocyte capping in muscular dystrophy.

We investigated lymphocyte capping in nine patients with muscular dystrophy (seven with Duchenne dystrophy and two with limb-girdle dystrophy), nine carriers, and five normal controls. No differences between the groups were observed. Thus, we have been unable to confirm a recent report that patients with muscular dystrophy, as well as carriers, have a defect in lymphocyte capping.
