Neurotrophin, p75, and Trk Signaling Module in the Developing Nervous System of the Marine Annelid Platynereis dumerilii

In vertebrates, neurotrophic signaling plays an important role in neuronal development, neural circuit formation, and neuronal plasticity, but its evolutionary origin remains obscure. We found and validated nucleotide sequences encoding putative neurotrophic ligands (neurotrophin, NT) and receptors (Trk and p75) in two annelids, Platynereis dumerilii (Errantia) and Capitella teleta (Sedentaria,...

15-P034 Expression of a Coe gene in the developing nervous system of the annelid Platynereis dumerilii

extant limpet. In addition, bivalves also acquired a novel structure, adducter muscle to close the separated shell plate. Because the two novel structures, the separated shell plate and the adducter muscle appear early embryonic stage, their evolution should be understood as a modification of early development. To understand the evolution of bivalve bodyplan, we have traced the cleavage pattern...
