Dystrophin-like immunoreactivity in monkey and human brain areas involved in learning and motor functions.
Two antidystrophin antibodies against different fragments of dystrophin were used to detect this polypeptide in monkey and human brains. Dystrophin was revealed by immunoperoxidase amplified with the biotin/avidin system and by immunoblotting. A dystrophin-like immunoreactivity was uniformly expressed in several brain regions implicated in learning and motor functions. Dystrophin function is not clear but our results raise the possibility that this protein may be involved in the cognitive impairment observed in several Duchenne muscular dystrophy (DMD) patients.
