Methamphetamine ( METH ) , a powerful stimulant of amphetamine type in the central nervous system ( CNS ) , is a new kind of synthetic drugs mainly in psychological dependence. Long-time abuse will lead to strong neurotoxicity and drug de-pendence. Recently it has become the abuse problem in public health. Autophagy is a process of degradation and utilization of the cellular components by the lysosome, which widely exists in eukaryotic cells. Many studies show that methamphetamine can iduce autophagy,but the underlying mechanism is not fully un-derstood yet . Therefore,the mechanisms and signaling pathways of autophagy by methamphetamine and the roles of autophagy in methamphetamine induce neurotoxicity are reviewed in this pa-per, so as to provide reference materials for further research of methamphetamine and autophagy.%甲基苯丙胺属于苯丙胺类中枢兴奋剂，是一种以精神依赖为主的新型合成毒品，长期滥用具有很强的神经毒性和药物依赖性。目前其滥用趋势严重，已成为当今全球最严重的公共卫生问题。自噬是广泛存在于真核细胞内的一种利用溶酶体对细胞自身成分进行一系列降解利用的过程。研究表明，甲基苯丙胺可诱导神经细胞自噬，但机制尚未明了。该文主要从甲基苯丙胺诱导神经细胞自噬的机制、信号转导通路及自噬在甲基苯丙胺神经毒性中的作用等方面进行综述，旨在为进一步研究甲基苯丙胺与自噬提供参考。
