This application is for a competitive renewal of the SRCS program of Dr. Pradeep K Dudeja. His program is focused on elucidating the mechanisms of regulation of electrolyte and fluid absorption in the human intestine in health and disease. His studies are aimed at understanding the pathophysiology of diarrheal diseases as it pertains to infectious diarrhea and inflammatory bowel diseases (IBD) associated diarrhea and to develop better therapeutic interventions. Diarrheal diseases are very common in our Veterans due to high incidence of IBD, infections and deployment related chronic illnesses and stress. Our program utilizes state-of-the-art approaches including human intestinal enteroids or mini guts and enteroid derived monolayers, organ-donor human intestine derived purified antipodal plasma membranes from various regions of the gut, in vitro molecular approaches and in vivo approaches utilizing knock out and transgenic mouse models to better understand the pathophysiology of diarrhea and to identify novel therapeutic targets. Our group has had a unique advantage of leading this field globally due to some of the pioneering techniques established by us using the organ donor human intestines. We have extensively published our work in over 220 original peer reviewed research articles in many prestigious journals in the field including Gastroenterology (impact factor 21) and J Clin Invest (12.3). We have also extensively defined the role of gut-microbe interactions in diarrheal diseases with respect to infectious diarrhea and the beneficial role of probiotics in these diseases. In addition, one of the key hallmarks of our program has been a multidisciplinary and collaborative nature of the research enterprise with a deep focus on mentoring new generation of VA and affiliated university investigators to enable them to establish their own independent research programs. We have been successful at both the fronts of making new discoveries in the field and mentoring new generation of young scientists and establishing a solid research environment at our local VA as well as at affiliated university. Our program has been continuously funded by multiple VA and NIH awards. This current application is intended to highlight the success of our program and requesting renewal of this SRCS program to continue the progress towards the new heights of success by nurturing and mentoring a new generation of investigators.

此申请用于 Pradeep K Dudeja 博士的 SRCS 计划的竞争性更新。他的程序是 专注于阐明人体肠道电解质和液体吸收的调节机制 在健康和疾病方面。他的研究旨在了解腹泻疾病的病理生理学，因为它 与感染性腹泻和炎症性肠病（IBD）相关的腹泻有关，并发展 更好的治疗干预措施。由于腹泻病的发病率很高，因此在我们的退伍军人中非常常见 IBD、感染和部署相关的慢性疾病和压力。我们的计划采用最先进的 方法包括人肠肠类或小肠和肠类衍生的单层、器官供体 人肠来源的纯化反足质膜，来自肠道的各个区域，体外 利用敲除和转基因小鼠模型的分子方法和体内方法更好地 了解腹泻的病理生理学并确定新的治疗靶点。我们组曾经有过一次 由于我们建立的一些开创性技术，在该领域处于全球领先地位的独特优势 使用器官捐献者的人体肠道。我们已在 220 多个原创同行中广泛发表了我们的研究成果 审阅了该领域许多著名期刊的研究文章，包括胃肠病学（影响因子 21) 和 J Clin Invest (12.3)。我们还广泛定义了肠道微生物相互作用在腹泻中的作用 有关感染性腹泻的疾病以及益生菌在这些疾病中的有益作用。此外， 我们项目的主要特点之一是研究的多学科和协作性质 专注于指导新一代 VA 和附属大学研究人员的企业 使他们能够建立自己的独立研究计划。我们在这两个方面都取得了成功 在该领域取得新发现并指导新一代年轻科学家的前沿 在我们当地的退伍军人事务部及其附属大学建立坚实的研究环境。我们的程序有 持续获得多项 VA 和 NIH 奖项的资助。当前的应用程序旨在强调 我们的计划取得了成功，并要求更新该 SRCS 计划，以继续朝着 通过培养和指导新一代调查人员，取得新的成功高度。
