| 内容記述 | The innervation of serotonergic nerve fibers to catecholamine (CA)-containing subependymal cells (cerebrospinal fluid-contacting neurons) was studied in the preoptic recess organ of the bullfrog brain by immunohistochemistry together with CA fluorescence histochemistry. Microspectrofluorometric analysis indicated that fluorescent subependymal cells in the preoptic recess organ contained mainly dopamine. By light microscopy, a number of serotonin (5HT)-immunoreactive fibers and terminals were distributed in subjacent neuropils of the subependymal layer. Double staining using the same section indicated that 5HT-immunoreactive punctate structures resembling axon terminals were situated around subependymal perikarya showing tyrosine hydroxylase (a marker enzyme for CA-containing neurons)-like immunoreactivity. A correlative analysis of the same specimen with fluorescence and electron microscopes revealed that CA-containing subependymal cells possessed numerous electron-dense granules (80-150 nm in diameter) within the perikaryal cytoplasm. Finally, immunoelectron microscopic examination confirmed that 5HT- positive nerve terminals were located closely adjacent to subependymal somata that contained similar granules to those of CA-containing cells. Although a typical synaptic feature has not yet been observed between the two structures, the present results strongly suggest that CA-containing subependymal cells receive input of serotonergic neurons via axo-somatic synapses. | |||||
