项目摘要

DESCRIPTION (provided by applicant): THE CANDIDATE: Dr. Tracy Carlson, a licensed veterinarian with board-eligibility in veterinary anatomic pathology, is completing a Ph.D. training program at the Ohio State University (OSU). The K01 SERCA will support her training and progression to scientific independence. THE ENVIRONMENT: OSU has an extensive biomedical research complex including state of the art core facilities in the Colleges of Medicine / Veterinary Medicine. Dr. Larry Schlesinger, the Principal Investigator's mentor, is the Director of both the Infectious Disease Division and the Center for Microbial Interface Biology. Dr. Schlesinger is an experienced mentor in the training of Ph.D. students and K award trainees. THE TRAINING PLAN: The first year of the K award will be used to support the completion of the Ph.D. training of Dr. Carlson in a mentored environment in Dr. Schlesinger's laboratory. The last four years will be used to facilitate Dr. Carlson's transition to an independent researcher following the plan outlined in the research proposal. This will foster eligibility for employment in competitive staff and faculty scientist positions. THE RESEARCH: The initial interaction of respiratory pathogens with the innate immune system is critical for determining the outcome of disease particularly for bacteria of the order Actinomycetales, such as Mycobacteria and Rhodococcus spp., which have the ability to live in innate immune cells (alveolar macrophages). Interaction of the local lung environment, in particular surfactant protein D, has antimicrobial effects on Mycobacterium tuberculosis in in vitro assays. In this research proposal we will further define the interaction of SP-D with M. tuberculosis and the effect it has on the survival of the bacteria in in vitro assays and in vivo in part by exploring the effect of SP-D mutations on the outcome of infection. Additional research will focus on the pulmonary host response to the related Rhodococcus equi, a bacterium that is a significant source of opportunistic pulmonary disease in immunocompromised (AIDS) patients as well as being an important cause of economic loss and morbidity as a disease of young horses. Defining and modulating the interaction of the pulmonary environment with these pathogens will open new avenues of investigation into potential targeted immunotherapies. PUBLIC HEALTH RELEVANCE: Tuberculosis is one of the leading causes of death due to a single infectious disease agent and infects ~ 1/3 of the world's population. The related Rhodococcus equi is an opportunistic infection in AIDS patients and a cause of economic loss / morbidity in the equine industry. Our project will define the initial interaction of these bacteria with the lung innate immune system and generate novel approaches to immunotherapy.

简介（由申请人提供）：候选人：特蕾西·卡尔森博士是一名有执照的兽医，具有兽医解剖病理学委员会资格，正在俄亥俄州立大学（OSU）完成博士学位培训计划。K01 SERCA将支持她的培训和科学独立的发展。环境：俄勒冈州立大学拥有广泛的生物医学研究综合体，包括医学/兽医学院最先进的核心设施。Larry Schlesinger博士是首席研究员的导师，也是传染病部和微生物界面生物学中心的主任。施莱辛格博士是博士研究生和K奖学员培训方面经验丰富的导师。培训计划：K奖的第一年将用于支持卡尔森博士在施莱辛格博士实验室的指导环境中完成博士培训。最后的四年将用于促进卡尔森博士按照研究提案中概述的计划过渡到独立研究员。这将促进在竞争激烈的教职员工和科学家职位就业的资格。研究：呼吸道病原体与先天免疫系统的初始相互作用对于决定疾病的结果至关重要，特别是放线菌目细菌，如分枝杆菌和红球菌，它们具有在先天免疫细胞（肺泡巨噬细胞）中生存的能力。在体外实验中，局部肺环境的相互作用，特别是表面活性剂蛋白D，对结核分枝杆菌有抗菌作用。在本研究计划中，我们将通过探索SP-D突变对感染结果的影响，进一步确定SP-D与结核分枝杆菌的相互作用，以及它在体外和体内对细菌存活的影响。进一步的研究将集中在肺宿主对相关马红球菌的反应上，马红球菌是免疫功能低下（艾滋病）患者机会性肺病的重要来源，也是小马经济损失和发病率的重要原因。定义和调节肺部环境与这些病原体的相互作用将为研究潜在的靶向免疫疗法开辟新的途径。
