title: Uptake of horseradish peroxidase in sensory nerve terminals of mouse trigeminal nerve.
abstract: Uptake of horseradish peroxidase (HRP) in sensory nerve terminals in sinus hair in the nose of the mice was studied after local (s.c.) or i.v. injections. HRP spread into the sinus hair follicles and surrounded the nerve terminals of the Merkel disc endings and lanceolate terminals. It was incorporated into vacuoles and vesicles of these terminals. Subsequently, HRP was demonstrated in nerve cell bodies in the ophthalmo-maxillary part of the trigeminal ganglion, indicating a somatopetal axonal transport of the tracer. In this way the sensory neurons may be subjected to various influences from the periphery.
