阐明先天性免疫系统提供针对病毒诱导的免疫缺陷的保护的机制。
哮喘的恶化。在更新我们的AADCRC计划时,我们将继续关注关键的
和经常未充分研究的先天免疫因子,表面活性剂的阴离子脂质,(棕榈酰-油酰-
磷脂酰甘油(POPG)和磷脂酰肌醇(PI))和Toll相互作用蛋白(Tollip),以及
表面活性蛋白-A(SP-A)。本申请提出三个相互关联的项目;该计划将
使用从表型良好的

POPG/PI、Tollip和SP-A作为独特的免疫调节剂起作用,其减弱病毒的作用。
感染2型哮喘,特别是RV-C,甲型流感和SARS-CoV-2。补充
功能性POPG/PI、SP-A和IL-33诱饵受体sST 2提供了新的替代方案,
哮喘中病毒感染引起的急性发作。使用人类样本作为SARS动物模型至关重要-
CoV-2,流感和RVC是有限的,并且将发现转化为人类疾病可能是可变的。因此,我们认为,

英文摘要
The overall goal of this Asthma and Allergic Diseases Cooperative Research Center (AADCRC) proposal is to
elucidate the mechanisms by which the innate immune system affords protection against viral-induced
exacerbations in asthma. In the renewal of our AADCRC program, we will continue to focus on the critical
and often understudied innate immune factors the anion lipids of surfactant, (palmitoyl-oleoyl-
phosphatidylglycerol (POPG) and phosphatidylinositol (PI)) and Toll interacting protein (Tollip) and
surfactant protein-A (SP-A). Three inter-related projects are proposed in this application; the program will
employ use of biologic airway and peripheral systemic specimen samples obtained from well-phenotyped
participants with and without type 2 asthma and atopy through Core B, the Clinical Core. We hypothesize that
POPG/PI, Tollip and SP-A function as unique immune modulators which attenuate the effects of viral
infections in type 2 asthma, specifically RV-C, influenza A and SARS-CoV-2. Supplementation of
functional POPG/PI, SP-A and the IL-33 decoy receptor sST2 offer novel alternatives to reduce
exacerbations due to viral infections in asthma. Use of human samples is critical as animal models of SARS-
CoV-2, influenza and RVC are limited, and translational of findings to human disease can be variable. Therefore,
the goal of the Clinical Core is to provide services for our AADCRC investigators to perform safe, consistent
procedures in research participants for phenotyping and standardized, high quality collection of biologic airway
and peripheral systemic specimens, cost effective sample processing and data collection, with robust data
management and statistical analysis to test the hypotheses presented in each project. This Clinical Core will
extensively phenotype 100 participants comprised of 60 asthma (30 mild, and 30 severe) patients and 40 controls
(25 atopic, 15 non-atopic) for lung function testing, type 2 phenotyping, genotyping, nasal sampling, and to
participate in the bronchoscopy studies to understand the effectiveness of these innate immune modulators in
asthma and atopy, and in mild and severe asthma. The Clinical Core will coordinate and perform bronchoscopy
with bronchoalveolar lavage, nasal and epithelial cell brushings, and endobronchial biopsy on all participants.
The Clinical Core will be responsible for processing, storing, and distributing all samples collected from
participants, to each of the three projects. In this capacity, the Core will allow each clinical sample to be utilized
to its full potential and serve all projects equally. For all of the studies within the AADCRC utilizing human subject
samples, the Clinical Core will also be responsible for assuring patient safety, data confidentiality and full
regulatory compliance. A Biostatistics Unit is embedded in this core to integrate the clinical data with the
molecular/biomarker data to effectively model relationships between cellular features and clinical phenotypes in
asthma.
