10. Our studies show that forward signaling through the EphA4 tyrosine kinase receptor, mediated by ephrins expressed by subpopulations of neuroblasts and astrocytes, is required for compact, directional organization of neuroblasts and astrocytes within the pathway and efficient transit of neuroblasts through the anterior forebrain to the olfactory bulb.

11. Findings suggest a putative novel mechanism for desipramine to modulate long-term potentiation through the regulation of the ephrinA3/EphA4 signaling pathway

1. In myelinating co-cultures and in zebrafish, we find that the number of mature oligodendrocytes does not change as result of manipulating signaling through the ephrinA1-EphA4 system. However, in both systems, inhibition of EphA4 signaling leads to a higher number of myelin sheaths formed by each oligodendrocyte. In isolated oligodendrocyte cultures, activation of EphA4 reduced process extension.
