title: Localization of coxsackie virus and adenovirus receptor (CAR) in normal and regenerating human muscle.
abstract: The primary receptor for Adenovirus and Coxsackie virus (CAR) serves as main port of entry of the adenovirus vector mediating gene transfer into skeletal muscle. Information about CAR expression in normal and diseased human skeletal muscle is lacking. C'- or N'-terminally directed polyclonal antibodies against CAR were generated and immunohistochemical analysis of CAR on morphologically normal and regenerating human skeletal muscle of children and adults was performed. In morphologically normal human muscle fibers, CAR immunoreactivity was limited to the neuromuscular junction. In regenerating muscle fibers, CAR was abundantly co-expressed with markers of regeneration. The function of CAR at the neuromuscular junction is currently unknown. Co-expression of CAR with markers of regeneration suggests that CAR is developmentally regulated, and may serve as a marker of skeletal muscle fiber regeneration.
