急性和慢性暴露于大麻素与认知缺陷,精神分裂症和其他药物滥用的风险较高有关。然而,这种影响背后的确切机制尚不清楚。临床前研究表明,大麻素调节脑源性神经营养因子(BDNF)。因此,我们假设大麻的主要活性成分Δ9-四氢大麻酚(Δ9-THC)会改变人类的BDNF水平。在一项双盲、固定顺序、安慰剂对照的实验室研究中,健康对照受试者(n=14)和大麻轻度使用者(n=9)接受静脉内施用(0.0286 mg/kg)Δ9-THC。使用ELISA测定在基线、安慰剂施用后和Δ9-THC施用后取样的血清中的BDNF。Δ9-THC增加了健康对照组的血清BDNF水平,但没有轻度大麻使用者。此外,轻度大麻使用者的基础BDNF水平较低。Δ9-THC产生拟精神病效应、知觉改变以及“高”和空间记忆障碍。社会相关剂量的大麻素对BDNF的影响表明了暴露于大麻的后果的可能机制。这可能对发育中的大脑以及被认为涉及神经发育改变的疾病(如精神分裂症)特别重要。研究大麻素对BDNF和其他神经营养因子的影响的更大的研究是必要的。
Acute and chronic exposure to cannabinoids has been associated with cognitive deficits, a higher risk for schizophrenia and other drug abuse. However, the precise mechanism underlying such effects is not known. Preclinical studies suggest that cannabinoids modulate brain-derived neurotrophic factor (BDNF). Accordingly, we hypothesized that Δ9-tetrahydrocannabinol (Δ9-THC), the principal active component of cannabis, would alter BDNF levels in humans. Healthy control subjects (n=14) and light users of cannabis (n=9) received intravenous administration of (0.0286 mg/kg) Δ9-THC in a double-blind, fixed order, placebo-controlled, laboratory study. Serum sampled at baseline, after placebo administration, and after Δ9-THC administration was assayed for BDNF using ELISA. Δ9-THC increased serum BDNF levels in healthy controls but not light users of cannabis. Further, light users of cannabis had lower basal BDNF levels. Δ9-THC produced psychotomimetic effects, perceptual alterations, and “high” and spatial memory impairments. The effects of socially relevant doses of cannabinoids on BDNF suggest a possible mechanism underlying the consequences of exposure to cannabis. This may be of particular importance for the developing brain and also in disorders believed to involve altered neurodevelopment such as schizophrenia. Larger studies to investigate the effects of cannabinoids on BDNF and other neurotrophins are warranted.
