Given the alterations in NRG1 and BDNF signaling pathways result in neuronal dysfunctions as well as the implication of NMDARs in neuroplasticity, our findings on the role of TrkB in NRG1-stimulated NR2B phosphorylation could be of relevance to many neurodevelopmental disorders, as NRG1 and BDNF signaling pathways have been implicated in autism and schizophrenia. This evidence concerns the gene NTRK2 and schizophrenia.
