摘要:

目的 探讨大麻素CB1受体(cannabinoid CB1 receptor,CB1R)的拮抗作用是否会影响慢性快速眼动(chronically rapid eye movement,CRM)睡眠剥夺(CRM sleep-deprived,RSD)大鼠的新物体识别(novel object recognition,NOR)记忆。

方法 采用多平台技术对动物进行为期7天的慢性部分RSD范式的识别记忆检查。CB1R拮抗剂利莫那班(1mg/kg或3mg/kg,腹腔内注射)在记忆获取采样前一小时、在记忆巩固采样后即时或在NOR记忆提取测试阶段前至少一小时进行注射。为实现记忆再巩固,在第二个采样阶段完成后即时注射利莫那班。

结果 RSD损害了NOR记忆的获取、巩固和提取,但不影响NOR记忆的再巩固。注射利莫那班不影响记忆的获取、巩固和再巩固;然而,它减轻了慢性RSD对NOR记忆提取造成的损害。

结论 这些发现以及我们之前的报告似乎表明,RSD可能因其持续时间不同而影响识别记忆的不同阶段。重要的是,CB1R似乎至少部分参与了慢性RSD对NOR记忆的提取,但与NOR记忆的获取、巩固和再巩固无关。

Abstract:

Objective We aimed to investigate whether antagonism of the cannabinoid CB1 receptor (CB1R) could affect novel object recognition (NOR) memory in chronically rapid eye movement sleep-deprived (RSD) rats.

Methods The animals were examined for recognition memory following a 7-day chronic partial RSD paradigm using the multiple platform technique. The CB1R antagonist rimonabant (1 or 3 mg/kg, i.p.) was administered either at one hour prior to the sample phase for acquisition, or immediately after the sample phase for consolidation, or at one hour before the test phase for retrieval of NOR memory. For the reconsolidation task, rimonabant was administered immediately after the second sample phase.

Results The RSD episode impaired acquisition, consolidation, and retrieval, but it did not affect the reconsolidation of NOR memory. Rimonabant administration did not affect acquisition, consolidation, and reconsolidation; however, it attenuated impairment of the retrieval of NOR memory induced by chronic RSD.

Conclusions These findings, along with our previous report, would seem to suggest that RSD may affect different phases of recognition memory based on its duration. Importantly, it seems that the CB1R may, at least in part, be involved in the adverse effects of chronic RSD on the retrieval, but not in the acquisition, consolidation, and reconsolidation, of NOR memory.
