项目摘要

PROJECT SUMMARY This CAUSE application brings together seasoned clinical and laboratory investigators in inner-city asthma, with expertise in clinical studies and clinical trials, immunology, genetics, environmental exposures, bioinformatics, data management, and statistics. The investigators have long track records in implementing multi-center and single-center clinical trials and observational studies in allergic diseases, including asthma, to the standards of NIH funded clinical research networks, in conducting NIH fundamental research on disease mechanisms in asthma and in training generations of investigators in asthma research In part A we demonstrate that we have the personnel and facilities to conduct asthma network-wide and Clinical Research center-specific research on inner-city children with asthma populations recruited from the allergy and asthma clinics at Boston Children's Hospital and from our just completed, as well as ongoing, NIH-funded studies of inner-city schoolchildren with asthma, allergic diseases and healthy controls. We have a highly experienced team, IRB-approved protocols for recruitment and clinical characterization of asthma patients and healthy controls and an infrastructure which includes clinical research facilities, investigational pharmacy services, a laboratory facility capable of processing, storing and shipping human samples, a state-of-the-art immunology research laboratory with a 25 year focus on asthma and a data management facility with quality control plans, and capability to upload data into the NIAID designated repositories and biostatistical support. In part B our Center specific project draws from previous work on the novel NOTCH4 pathway and airway inflammation and will draw on an already well-characterized urban school population of asthma patients and healthy controls. Our overall hypothesis is that NOTCH4 signaling acts to regulate airway inflammation and increases asthma severity and loss of control in inner-city school children. Our aims are to 1) test the hypothesis that elevated peripheral blood NOTCH4+ Tregs defines a population of patients whose asthma is driven by an IL-6 dependent mechanism that confers a more severe or poorly controlled phenotype 2) determine the environmental determinants of the NOTCH4+ Tregs and how they mediate disease severity and control and 3) investigate whether regulatory variants that increase NOTCH4 protein expression are associated with more severe asthma phenotypes and endotypes. This project will confirm the role of environmental exposures we have found important in urban schools and homes of children with asthma and that regulatory variants that impact signaling may be modified by novel mechanistic gene by environment pathways. We will elucidate novel mechanisms fundamental to the biology of airway inflammation and pave the way for future biomarker driven approaches to inform future precision therapy. We address a critical knowledge gap in reducing disproportionate asthma burden in vulnerable individuals. We will contribute extensively to the CAUSE as a CAUSE-Clinical Research Center, with our infrastructure and expertise.
