Abstract
It has previously been shown that cephalic, segmental, and caudal ganglia from the medicinal leech show differences in their protein composition. Here we studied whether the neuronal reorganization that occurs in cultured segmental ganglia from the medicinal leech is accompanied by detectable changes in the protein expression pattern. Using silver-stained two-dimensional gels we showed that after 5 and 12 days in culture changes in the protein patterns can be detected in isolated ganglia. The changes observed in the two-dimensional gels occurred concomitantly with a sprouting of serotoninergic neurites and a decreased transmitter content of dopaminergic neurites as shown by using the glyoxylic acid condensation reaction. In addition, we present evidence that Retzius cells, which can be identified by their characteristic morphology and action potential waveform, exhibit biochemically unique properties with respect to their protein expression pattern.
