Ultrastructural and pharmacological studies on the afferent synapse of lateral-line sensory cells of the African clawed toad, Xenopus laevis

P Monaghan. Cell Tissue Res. .

Abstract

Lateral-line sensory cells of Xenopus show considerable similarity to central nervous system synapses in their responses to the zinc iodide-osmium tetroxide, and bismuth-iodide cytochemical staining techniques. Both reserpine and FLA-63 cause a reduction in the diameter and electron density of the synaptic bars, and a dramatic loss of synaptic vesicles surrounding the bars. Aminooxy acetic acid and 3-mercaptopropionic acid cause no significant changes in the sensory-cell afferent synaptic apparatus. The results are discussed in the light of the known effects of the drugs. It is concluded that a monoamine rather than an amino acid may act as the afferent transmitter.
