A systematic review of neuron synaptic plasticity in hioppocampus in the pathogenesis of depression / 中华行为医学与脑科学杂志

ABSTRACT

Objective To review the neuron synaptic plasticity in hioppocampus in the pathogenesis of depression in present studies,and expected to provide reference and basis for study of depression in clinic and model.Methods The wordsdepression, antidepression, chronic unpredictable stimulate, hippocampus, synapse,plasticity were used as index words.Analysis the relationship of depression or antidepression and synaptic plasticity in hippocampus from the results of researches enrolled at home or abroad.Summarize the effect of neuron synaptic plasticity in hioppocampus in the pathogenesis of depression.Result Totally 37 articles enrolled.They show the onset of depression or antidepressant processes always combine with the damage or recover of neuron synaptic plasticity.Conclusion The reduction or damage in synaptic plasticity in hippocampus is likely to be the pathogenesis of depression,like the changes of function or expression of SYN-1,MAP-2,SYT-1,PSD-95 or any other synapse-associated proteins.Meanwhile,studies of using enrich environment to treat depression indicated that depression is likely related to the synaptic plasticity in hippocampus in another way.But who are the synapse-associated proteins related to synaptic plasticity in depression? How to design the enrich environment.? These still need further study.
