- W2092245909 abstract "Background Changes in densities and in the morphology of dendritic spines in the hippocampus are linked to hippocampal long-term potentiation (LTP), spatial learning, and depression. Decreased brain-derived neurotrophic factor (BDNF) levels seem to contribute to depression. Through its receptor trkB, BDNF is also involved in hippocampal LTP and hippocampus-dependent learning. Conditionally gene-targeted mice in which the ablation of trkB is restricted to the forebrain and occurs only during postnatal development display impaired learning and LTP. Methods To examine whether there is a link among impaired hippocampal synaptic plasticity, altered spines, and trkB receptors, we performed a quantitative analysis of spine densities and spine length in the hippocampal area CA1 and the dentate gyrus in conditional mutant mice (trkBlox/loxCaMKII-CRE mice). TrkB protein and mRNA levels were assayed using Western blot and in situ hybridization analysis. Results Fifteen-week-old mutant mice exhibit specific reductions in spine densities and a significant increase in spine length of apical and basal dendrites in area CA1. These alterations correlate with a time- and region-specific reduction in full-length trkB mRNA in the hippocampus. Conclusions TrkB functions in structural remodeling of hippocampal dendritic spines, which in turn may affect synaptic transmission and plasticity.
