Axon and target communicate to organize synaptic differentiation.

synapse organizers

Key Presynaptic organizers: NT-7a, neuroligin, synaptic cell adhesion molecule (SynCAM) and fibroblast growth factor-22 (FGF-22) have all been identified as target-derived presynaptic organizers Key Postsynaptic organizers: axon-derived neuronal activity regulated pentraxin (Narp), ephrinB and neurexin reciprocally co-ordinate postsynaptic differentiation. Seeking long-term relationship: axon and target communicate to organize synaptic differentiation. J Neurochem. 2006 Jun;97(5):1215-31. Epub … Continue reading
