项目摘要

Twenty-eight years after the discovery of the CFTR gene, the causes of cystic fibrosis (CF) airway disease remain controversial, we still lack answers to many critical questions, our therapies are inadequate, and CF remains a life limiting and too often lethal disease. A major impediment to progress has been lack of CF animal models with a lung disease phenotype resembling humans with CF. We developed pigs with targeted alterations of the CFTR gene. CF pigs spontaneously develop the hallmark features of CF lung disease, including airway infection, inflammation, airway wall remodeling, mucus accumulation, and airway obstruction. Within hours of birth, CF pigs fail to eradicate bacteria as effectively as wild-type pigs. At least two host defense defects, reduced antimicrobial activity in airway surface liquid (ASL) and impaired mucociliary transport (MCT) contribute. Both were caused by abnormally acidic airway liquid. In this Program three highly accomplished investigators will use CF pigs to answer fundamental questions about CF lung disease. Together, the three projects will discover how loss of CFTR function affects: a) submucosal gland function, the properties of mucus, and MCT; b) ASL pH and proton secretion via ATP12A; and, c) small airways function, a likely site of CF disease pathogenesis. The Project Leaders and their teams have an outstanding track record of collaborative CF research, and here they sharpen their focus to a common goal. Their highly creative research is supported by five cores that provide innovative infrastructure and services. By further educating CF pathogenesis, it will accelerate discovery of novel therapies for this lethal disease.

CFTR 基因发现 28 年后，囊性纤维化 (CF) 气道的病因疾病仍然存在争议，我们仍然缺乏许多关键问题的答案，我们的疗法是不足，CF 仍然是一种限制生命且常常致命的疾病。进步的主要障碍一直缺乏具有与人类 CF 相似的肺部疾病表型的 CF 动物模型。我们培育出具有 CFTR 基因定向改变的猪。 CF猪自发地表现出该特征 CF肺部疾病的特征，包括气道感染、炎症、气道壁重塑、粘液积聚和气道阻塞。 CF 猪在出生后数小时内无法消灭细菌，因为与野生型猪一样有效。至少有两个宿主防御缺陷，气道抗菌活性降低表面液体（ASL）和受损的粘膜纤毛运输（MCT）有影响。两者都是由气道液体呈异常酸性。在此计划中，三位卓有成就的研究人员将使用 CF 猪回答有关 CF 肺病的基本问题。这三个项目将共同探索如何 CFTR 功能丧失会影响： a) 粘膜下腺功能、粘液特性和 MCT； b) 美国手语 pH 值和通过 ATP12A 的质子分泌； c) 小气道功能，这是 CF 疾病的可能部位发病。项目负责人及其团队在协作 CF 方面拥有出色的记录研究，在这里他们将注意力集中到一个共同的目标。他们极具创造性的研究是由提供创新基础设施和服务的五个核心支持。通过进一步教育CF 发病机制，它将加速发现这种致命疾病的新疗法。
