Axonal transport of neuropeptides: Retrograde tracing study in live cell cultures of rat sympathetic cervical ganglia.
Previous studies demonstrated that neuropeptides are transported with fast axonal transport. Considerable amounts (30-40%) of anterogradely transported peptides accumulated distal to a crush, apparently recycling to the cell bodies. In the present study, we used primary and compartmented cultures of sympathetic cervical ganglia (SCG) to address questions on the origin of the recycling peptides. In
