光遗传技术在可卡因成瘾机制中的应用

Advance in optogenetic application of cocaine addiction mechanisms

目的 运用系统综述方法评价光遗传技术在可卡因成瘾机制中的应用.方法 以“光遗传技术”、“成瘾”、“可卡囚”等为关键词,通过检索中国期刊全文数据库、中国生物医学数据库、万方数字化全文期刊、维普全文数据库以及PubMed、SCIENCEDIRECT、SPRINGERLIN数据库,筛查符合纳入标准的文献,采用了定性系统综述.结果 分析纳入的文献后,结果显示：光遗传技术具有高空间及时间分辨率、低组织损伤等优势,其应用不仅证明了传统的中脑边缘多巴胺系统理论在可卡因成瘾机制中的重要作用,也弄清了相关核团之间的部分投射关系.关于多巴胺、谷氨酸等神经递质、突触重塑的分子机制研究也因此取得了飞速的进展.结论 光遗传技术的应用赋予了实验研究在探索成瘾涉及的神经回路和分子机制方面极大的潜力,为深入了解可卡因成瘾的机制开辟了新的路径,为成瘾的治疗方法开拓了广阔的前景。

Objective To integrate existing data and analyze the optogenetic application in the study of the cocaine addiction mechanism.Methods The key words ＂optogenetics＂,＂addiction＂,＂ cocaine＂ and so on were selected.Relevant research information was collected from various authentic databases such as China Journal Full-text Database,Chinese Biomedical Databases,Wanfang Digital Journals,VIP Full-text Database and PubMed,SCIENCEDIRECT,SPRINGERLINK databases by literature study,assess the quality of the studies and the qualitative systematic review was conducted in this study.Results Findings from present data showed that：with great spatial and temporal specificity,the optogenetic application not only proved the important role of traditional theories of mesolimbic dopamine system,but also dissected the neural circuits and molecular mechanisms of dopaminergic and glutamatergic neurotransmission underlying cocaine addiction.Conclusion The use of optogenetic tools has given researchers the potential to dissect the neuronal circuits and molecular changes,leading us to a better understanding of the mechanisms of cocaine addiction and to the development of novel treatment.
