中文摘要
项目摘要(资助的奖学金,U19 AI 142733)
我们建议在杰克逊实验室(JAX CCHI)建立一个U19人类免疫学合作中心,
阐明先天免疫网络,形成适应性免疫反应,呼吸道病毒感染,
人类的肺上皮屏障位于宿主和环境之间的界面,在那里它们感觉到入侵
病原体树突状细胞(Dendritic cells,DC)将病原体来源的抗原呈递给T和B细胞以诱导免疫应答。
然而,人肺组织环境对DC和其他细胞的影响,如新发现的
先天性淋巴样细胞(ILC)家族以及细菌反应性MAIT细胞尚未完全了解。一个
研究不足的环境因素是肺部微生物组。已知微生物群会严重调节
免疫细胞的功能,特别是在粘膜表面,但这是如何发生在肺没有完全解决。
JAX CCHI试图使用多学科实验方法来解决这些关键问题,
将免疫学与上皮细胞生物学沿着与基因组,细胞,功能和微生物组相结合
在人肺组织中鉴定的参数。我们的首要假设是,
粘膜T细胞对呼吸道病毒感染的反应是由微生物群之间的相互作用决定的,
上皮细胞和白细胞。为了解决这个假设,我们围绕两个集成的

英文摘要
PROJECT SUMMARY (FUNDED PARENT AWARD, U19AI142733)
We propose a U19 Cooperative Center on Human Immunology at The Jackson Laboratory (JAX CCHI) to
elucidate the innate immune networks that shape adaptive immune responses to respiratory viral infections in
the human lung. Epithelial barriers lie at the interface between host and environment, where they sense invading
pathogen. Dendritic cells (DCs) present pathogen-derived antigens to T and B cells to induce immune responses.
However, the impact of the human lung tissue environment on DC and other cells, such as the newly identified
innate lymphoid cell (ILC) family, as well as bacteria-reactive MAIT cells, is not completely understood. An
understudied environmental factor is the lung microbiome. Microbiota are known to critically modulate the
function of immune cells, particularly at mucosal surfaces, but how this occurs in the lung is not fully addressed.
The JAX CCHI seeks to address these critical questions using a multi-disciplinary experimental approach that
will integrate immunology with epithelial cell biology along with genomic, cellular, functional and microbiome
parameters identified in human lung tissues. Our overarching hypothesis is that the quality and magnitude of
mucosal T cell responses to respiratory viral infections are determined by the cross- talk between microbiota,
epithelial cells and leukocytes. To address this hypothesis, we structured the JAX CCHI around two integrated
research projects focused on basic immunological mechanisms of lung antiviral immunity; a technology
development project that will create sophisticated cellular models leveraging 3D bioprinting, gene editing tools
and microbiome-immune assays to support project objectives; a sample core for storage and distribution of
human tissues; and a microbiome core for specialized microbiome profiling, cultivation, and computational
analysis. Our Center will bring together clinicians with experts in lung immunology, the microbiome,
bioengineering, genomics and computational biology to achieve our goals and maximize the potential of this
research. An administrative core will provide coordination, communication and oversight for the program. The
goals of this CCHI are to: 1) Understand how the networks of epithelial cells and immune cells in the human lung
regulate innate and adaptive immunity to respiratory viruses; 2) Define how inflammation driven by the
microbiome dictates the steady state of tissue, i.e., immune set-point; 3) Determine if and how this immune set-
point is altered in two pulmonary diseases, childhood asthma and adult lung cancer, which have a major impact
on public health; and 4) Develop innovative technologies to model human lung-immune dynamics and elucidate
molecular mechanisms, cell types and pathways key to lung antiviral responses. Impact: Through studies
focused on the sensors, inducers and modulators of antiviral immunity in the human lung, our CCHI will contribute
insights that could help improve outcomes for infectious and other immune diseases that originate in or
secondarily impact the lung.
