项目摘要

PROJECT ABSTRACT Nicotine is the primary addictive constituent in tobacco. For an individual, chronic tobacco use is associated with a significant increase in heart disease and many forms of cancer; even the health of non-tobacco users is negatively affected by second-hand smoke. There are some important sex differences in this addiction and its health consequences. Women on average take less time than men to become nicotine dependent, make fewer attempts to quit smoking, abstain for less time, relapse at higher rates, and benefit less from nicotine replacement therapy. Clearly, enormous gains to the individual and society would come from a better understanding of factors that contribute to nicotine dependence. Environmental stimuli associated with drugs such as nicotine can be powerful modulators of drug-seeking behavior. Another important factor to the development and tenacity of nicotine dependence is the pharmacological effects of nicotine serving as an interoceptive (internal) stimulus entering into a conditioned association with other reinforcers/unconditioned stimuli [USs (peer acceptance, alcohol, work breaks, stress relief)]. Consequently, over time, a smoker has an opportunity to develop a rich appetitive conditioning history with the stimulus effects of nicotine. This acquired reinforcing value likely contributes to the tenacity of the nicotine addiction. Using a newly developed preclinical animal model that innovatively merges interoceptive conditioning with nicotine self-administration, the present application will rigorously test the hypothesis that following an appetitive interoceptive conditioning history with nicotine, the nicotine stimulus will acquire conditioned reinforcing value that exacerbates the persistence of nicotine-taking behavior. To this end, the Specific Aims will examine how such enhancement of drug intake varies with the salience (dose) of the nicotine stimulus (Aim 1), assess the synergy between nicotine and ethanol by using ethanol or sucrose-ethanol solution as the US (Aim 2), and implement an innovative extinction protocol designed to weaken the acquired conditioned reinforcing value of nicotine to a greater extent than just simple non-reinforcement of the target stimulus (Aim 3) in female and male rats.

项目摘要尼古丁是烟草中主要的成瘾成分。对于个人而言，长期吸烟与心脏病和多种癌症的发病率显着增加；即使是不吸烟者的健康也受到影响受到二手烟的负面影响。这种成瘾及其后果存在一些重要的性别差异健康后果。女性平均比男性花费更少的时间产生尼古丁依赖，产生的尼古丁更少尝试戒烟，戒烟时间较短，复吸率较高，从尼古丁中获益较少替代疗法。显然，个人和社会的巨大收益将来自于更好的了解导致尼古丁依赖的因素。与药物相关的环境刺激例如尼古丁可以成为药物寻求行为的强大调节剂。另一个重要因素尼古丁依赖的发生和持续是尼古丁作为一种药物的药理作用。内感受（内部）刺激进入与其他强化物/无条件的有条件关联刺激[US（同伴接受、酒精、工作休息、缓解压力）]。因此，随着时间的推移，吸烟者会有机会利用尼古丁的刺激作用来发展丰富的食欲调节历史。这获得了强化价值可能有助于尼古丁成瘾的顽固性。使用新开发的创新性地将内感受调节与尼古丁自我给药相结合的临床前动物模型，本申请将严格检验以下假设：在食欲内感受之后尼古丁调节历史，尼古丁刺激将获得条件强化值，加剧尼古丁摄入行为的持续性。为此，具体目标将研究如何药物摄入量的增加随尼古丁刺激的显着性（剂量）而变化（目标 1），评估协同作用尼古丁和乙醇之间通过使用乙醇或蔗糖乙醇溶液作为美国（目标2），并实施一种创新的消除协议，旨在削弱尼古丁的后天条件强化价值比在雌性和雄性大鼠中简单地不强化目标刺激（目标 3）更大的程度。
