人们对 GABAB 受体 (GABABR) 在维持与使用滥用物质相关的记忆中的作用知之甚少。我们已经开展了一系列研究,旨在确定用正变构调节剂 (PAM) 增强 GABA 占据的 GABABR 的功效是否可以消除先前建立的由甲基苯丙胺诱导的条件性位置偏好 (CPP)。在本研究中,我们评估了 GABABR PAM、GS39783 和 CGP7930 急性给药的效果。我们确定,在家里的笼子中使用这些 PAM 进行后处理,可以阻断甲基苯丙胺诱导的 CPP 的后续表达。这些数据表明,选择性增强 GABA 占据的 GABABR 信号传导足以减少记忆维持和/或先前与甲基苯丙胺相关的上下文线索的显着性。
Little is known about the role of GABAB receptors (GABABRs) in the maintenance of memories associated with using abused substances. We have embarked on a series of studies designed to determine if enhancing the efficacy of GABA-occupied GABABRs with positive allosteric modulators (PAMs) can negate previously established conditioned place preference (CPP) induced by methamphetamine. In the current study, we evaluated the effects of acute administration of GABABR PAMs, GS39783 and CGP7930. We determined that post-conditioning treatments with these PAMs, administered in the home cage, blocked the subsequent expression of methamphetamine-induced CPP. These data indicate that selectively augmenting GABA-occupied GABABR signaling is sufficient to reduce memory maintenance and/or the salience of contextual cues previously associated with methamphetamine.
