Operant Vapor Self-administration in Mice

Type: article
Abstract: Models of drug addiction in rodents are instrumental in understanding the underlying neurobiology. Intravenous self-administration of drugs in mice is currently the most commonly used model; however, several challenges exist due to complications related to catheter patency. To take full advantage of the genetic tools available to study opioid addiction in mice, we developed a non-invasive mouse model of opioid self-administration using vaporized fentanyl. This model can be used to study various aspects of opioid addiction including self-administration, escalation of drug intake, extinction, reinstatement, and drug seeking despite adversity. Further, this model bypasses the limitations of intravenous self-administration and allows the investigation of drug taking over extended periods of time and in conjunction with cutting-edge techniques such as calcium imaging and in vivo electrophysiology., [摘要]啮齿类动物的成瘾模型有助于理解潜在的神经生物学。小鼠中药物的静脉内自我给药是目前最常用的模型。^ h H但是,几个challeng ES存在由于与导管通畅并发症。为了充分利用可用于研究小鼠阿片类药物成瘾的遗传工具 ,我们开发了使用汽化芬太尼的阿片类药物自我给药的非侵入性小鼠模型。该模型可用于研究阿片类药物成瘾的各个方面,包括自我管理,药物摄入量增加,灭绝,恢复原状和在逆境中寻求药物。此外,该模型绕过静脉内自我给药的限制,并允许药物的服用时间,并与切削结合在延长的时间段的调查-边缘技术如钙成像和在体内电生理学。[背景技术]蒸气吸入正在成为药物的自我管理(而不是静脉内),以研究成瘾替代路线对阿片样物质和其它药物。这已在大鼠中已经完成使用醇(Vendruscolo和Roberts ,2014 ;德古列尔莫等人。,2017) ,烟碱(史密斯等人。,2020) ,大麻(Freels等人,2020 ; Muthusamy ,2020年),和阿片类药物如舒芬太尼(Vendruscolo等人。,2018) ,芬太尼(麦康奈尔等人,2020) ,和海洛因(Gutierrez的等人。,2020) 。最近,我们采用了这种模型和开发阿片V的小鼠模型中使用芬太尼APOR自给药(穆萨维等人。,2020),T他用于协议,其在该手稿中描述。协议概述:将小鼠(雄性和雌性)进行培训,以自我管理芬太尼蒸气为1 - ħ会话,在此期间在有源operandum(活性杠杆按压或探鼻到有源端口)每个响应触发上的定点蒸气输送比1(FR1)加固时间表(这可以被调整到更高的FR,例如,3,5 ,或10)(视频1 )。每次蒸汽输送后都有60 s的超时时间,在此期间记录了对操作数的其他响应,但不会导致额外的药物输送。提示灯指示超时时间,提示灯在超时期间保持打开状态并保持开启状态。记录了无效的操纵杆/操纵杆端口上的操作活动,但没有任何后果。达到稳定压制后( 视频1 。视频显示了老鼠自用芬太尼蒸气。请注意,由于芬太尼的摄入和蒸气输送后的条状尾部反应而引起的运动增加。转载/改编自Moussawi等。(2020)。©作者,保留部分权利;独家被许可人,美国科学促进会。根据知识共享署名非商业许可4.0(CC BY-NC)分发,网址为http://creativecommons.org/licenses/by-nc/4.0/。
