DESCRIPTION (provided by applicant): This proposal from the Mycobacteria Research Laboratories, Colorado State University, is for competitive renewal of program AI-44072, "Chronic tuberculosis: latent or dynamic?" which in the previous funding period has made substantial progress in each of its Aims. In this new proposal, we wish to continue to try to define the immunological mechanisms that control and maintain the integrity of the chronic disease state, which we believe will ultimately provide a better understanding of the basis of latent tuberculosis in humans. In this proposal the first objective is to better define the role of IL-10, and to determine its potential role in reactivation disease in mouse strains prone to this event. The second Aim is to continue our studies on the role of CD8 T cells during the chronic disease state, given the accumulating evidence that they play an important role in maintaining the integrity of this process. A third Aim takes advantage of a new microarray laboratory recently established in the MRL. Using this facility we intend to try to provide a global picture of gene expression [concentrating initially on cytokines, chemokines, and their receptors] as the immune response in the lungs develops from containment, through the chronic disease state. Finally, in a fourth Aim, we propose to continue to develop new animal models that may provide new information about chronic/latent tuberculosis. The proposed work will take advantage of the advanced biosafety level III facilities at CSU, the broad expertise of various members of the Mycobacteria Research Laboratories, CSU, as well as a number of highly qualified consultants collaborators.

描述（由申请人提供）：科罗拉多州立大学分枝杆菌研究实验室的这一建议是为了竞争计划AI-44072，“慢性结核病：潜伏还是动态？”在上一个资金期间，每个目标都取得了重大进展。在这一新提案中，我们希望继续尝试定义控制和维持慢性疾病状态完整性的免疫机制，我们认为这将最终可以更好地理解人类潜在结核的基础。在此提案中，第一个目标是更好地定义IL-10的作用，并确定其在容易发生此事件的小鼠菌株中的潜在作用。第二个目的是继续我们对CD8 T细胞在慢性疾病状态中的作用的研究，因为积累的证据表明它们在维持该过程的完整性中起着重要作用。第三个目标利用了最近在MRL建立的新的微阵列实验室。使用此设施，我们打算尝试提供基因表达的全球图像[最初集中在细胞因子，趋化因子及其受体上]，因为肺部的免疫反应是通过慢性疾病状态从抑制而发展而来的。最后，在第四个目标中，我们建议继续开发新的动物模型，以提供有关慢性/潜在结核病的新信息。拟议的工作将利用CSU的高级生物安全III设施，这是Mycobacteria Research Laboratories，CSU的广泛专业知识，以及许多高素质的顾问合作者。
