Research Abstract |
Following glucocorticoid(stress hormone) exposure, BDNF-dependent synaptic maturation was decreased in cultured cortical neurons. We found that shp2-TrkB interaction, which is important for BDNF-mediated synaptic protein expression, was also reduced. In vivo models, we examined possible change of BDNF-related intracellular signaling in forebrain after restraint stress. We found that significant GR downregulation after restraint operation and confirmed a decrease in BDNF-stimulated neurotransmitter release.
