BDNF is a neurotrophic peptide that regulates synaptic plasticity. New work by Lu and coworkers in this issue of Neuron now identifies BDNF as a gatekeeper of synaptic and behavioral plasticity in cocaine sensitization. In the medial prefrontal cortex, upregulated BDNF facilitates LTP and contributes to neurobehavioral adaptations to psychostimulants.
脑源性神经营养因子(BDNF)是一种调节突触可塑性的神经营养肽。陆及其同事在本期《神经元》杂志上发表的新研究现已确定BDNF是可卡因致敏中突触和行为可塑性的守门人。在内侧前额叶皮层中,上调的BDNF促进长时程增强(LTP),并有助于对精神兴奋剂产生神经行为适应性变化。
