DESCRIPTION (provided by applicant): Chronic pain remains a major burden on society, significantly affecting millions of people and costing the populace billions annually. Despite major advances made to our understanding of pain, very few novel therapies have successfully translated to clinical care. A particular shortfall in this translation is due to the lack of a reliable, high-throughput, commercially available in vivo assay in rodents, particularly in mice. To address this deficit, we propose an innovative, automated, operant behavioral approach for assessing pain in rodents, with our long-range goal being the establishment of an operant model system that will quickly, systematically, and effectively evaluate pain. The central hypothesis is that operant assays can provide a sensitive, reliable, and clinically relevant way to evaluate sensory and nociceptive processing. One specific aim will be investigated: to evaluate a mouse operant model of thermal hyperalgesia and allodynia as compared to the rat operant model for studying pain. We will test this aim using an extremely innovative, automated, high-throughput approach for testing pain and analgesia in mice and rats. This includes using a reward-conflict strategy for assessing thermal pain. The rationale for the proposed research is that use of these operant assays in rats and mice to evaluate pain will provide a better method for future investigation of the mechanisms underlying pain disorders. This study explores an innovative approach for evaluating animal models of pain and would significantly advance the development of new treatments by providing a quick and reliable pain testing system using rodents. The product and process to be developed is an automated, user-friendly, investigator-independent, high-throughput, in vivo pain and analgesic testing system. We are particularly well-suited to complete this body of work, given the pairing of Stoelting Company's expertise in developing the product and Drs. Neubert and Caudle's pain-research experience. This line of research is significant because it explores a novel, high-throughput method to assess pain and pain relief following analgesic administration. If this line of research is successful, the result will have a significant impact on the way new pain-relieving therapies are screened and evaluated, ultimately allowing for a great reduction in the time for new drugs to become available clinically.

描述（由申请人提供）：慢性疼痛仍然是社会的重大负担，严重影响了数百万的人，每年损失数十亿人口。尽管我们对疼痛的理解取得了重大进展，但很少有新型疗法成功地转化为临床护理。这种翻译中的特殊缺点是由于缺乏可靠的，高通量的，在啮齿动物中，尤其是在小鼠中的体内分析中可获得的。为了解决这种赤字，我们提出了一种创新，自动化的操作行为方法，用于评估啮齿动物的疼痛，我们的长期目标是建立操作模型系统，该模型系统将迅速，系统地，系统地，有效地评估疼痛。 中心假设是操作分析可以提供一种敏感，可靠且与临床相关的方法来评估感觉和伤害性处理。将研究一个具体目标：与研究疼痛的大鼠操作模型相比，评估热痛觉过敏和异常性疾病的小鼠操作模型。我们将使用极其创新的，自动化的高通量方法来测试小鼠和大鼠的疼痛和镇痛作用。这包括使用奖励冲突策略来评估热痛。拟议的研究的理由是，在大鼠和小鼠中使用这些手术测定法来评估疼痛将为将来研究疼痛障碍的机制提供更好的方法。这项研究探讨了一种用于评估疼痛动物模型的创新方法，并通过使用啮齿动物提供快速可靠的疼痛测试系统来显着推动新疗法的发展。要开发的产品和过程是一种自动化，用户友好的，与研究者无关的，高通量，体内疼痛和止痛测试系统。考虑到Stoelting Company在开发产品和DRS方面的专业知识的配对，我们特别适合完成这项工作。 Neubert和Caudle的疼痛研究经验。这一研究很重要，因为它探索了一种新型的高通量方法，以评估止痛药后评估疼痛和疼痛的缓解。如果这一研究成功，结果将对新的疼痛疗法进行筛查和评估的方式产生重大影响，最终使新药在临床上可用时大大减少。
