title: Calcitonin gene-related peptide-like immunoreactive sensory fibers form synaptic contact with sympathetic neurons in the rat celiac ganglion.
abstract: The present study demonstrates synaptic contact between calcitonin gene-related peptide (CGRP)-like immunoreactive axon terminals and sympathetic neurons in the rat celiac ganglion. Our observations suggest that sensory ganglion neurons directly regulate the sympathetic activity via synapses, because CGRP immunoreactive (CGRPI) fibers in this ganglion are supplied by the sensory ganglia.
