摘要
在神经病理痛的发生、发展和维持中,内源性大麻素系统在神经系统从定位到表达水平都发生着动态变化。这些变化存在有利的一面,也存在不利的一面。外源性给予内源性大麻素在不同的疼痛模型中都产生了镇痛作用,且通过阻断大麻素受体发现内源性大麻素镇痛作用的发挥主要由大麻素CB1及CB2受体介导。抑制内源性大麻素降解酶在不同的疼痛模型中也表现出了镇痛作用,这种作用主要是因为增加了局部内源性大麻素含量水平。
Endocannabinoids and cannabinoid receptors are expressed in various central pain modulation regions. ~hey maintain in dynamic changes in the expression level and distribution under different pathological and physiological conditions. These changes possess advantage as well as disadvantage. Exogenous administration of endocannabinoids exerts analgesic effect in different pain models, which is mainly mediated by the cannabinoid CB1 and CB2 receptors. Inhibition of enzymes for degrading endocannabinoids in different pain models also shows analgesic effect due to the increased local levels of endocannabinoids.
