项目摘要
ABSTRACT – PROJECT 1
Endometriosis is a chronic, estrogen-dependent, inflammatory disease that affects ~10% of reproductive age
women, resulting in debilitating pelvic pain, infertility, and compromised quality of life. It is characterized by
anatomically and phenotypically diverse lesions of endometrial-like tissue superficially on the pelvic peritoneum,
the ovaries and deeply infiltrating into pelvic organs, with resulting neuroangiogenesis, fibrosis, adhesions, pelvic
pain and infertility. The pathogenesis of endometriosis relies on complex interactions between endometrial,
peritoneal mesothelial and connective tissue cells and activation of local immune cell responses. There is
profound dysfunction of the innate and adaptive immune systems, associated with inefficient lesion clearance
and pelvic and systemic inflammation. As clinical classifications of endometriosis are maladapted to the
heterogeneity of disease expression, diagnostics as well as effective treatments are lacking. Thus, precise
understanding of the cellular and molecular pathobiology of endometriosis is a critical prerequisite to improve
disease classification and inform diagnostic and therapeutic interventions. The goal of Project 1 is to determine
the contribution of the immune system to the pathobiology of endometriosis on a single cell level, and using a
data-driven strategy to derive and molecularly characterize objective disease classification. In Aim 1, we will
determine the cellular composition and functional attributes of endometriosis lesions, their surrounding
peritoneal/serosal niches, and eutopic endometrium through the lens of transcriptomic signatures at single cell
resolution. Our hypothesis is that lesions and their niche environments have unique and functionally relevant
transcriptomic signatures. In Aim 2, we will determine the contribution of the local and peripheral immune system
to the pathobiology of endometriosis leveraging CYTOF technology. We will test the hypothesis that the local
and peripheral myeloid phagocyte systems are dysfunctional in women with endometriosis. Local and systemic
immunological data will be integrated to identify immunological signatures of dysfunctionality and to differentiate
endometriosis disease types, along with functional studies. Finally, in Aim 3, we will leverage unsupervised
machine learning techniques to integrate single-cell assessment of endometriosis lesions, surrounding tissue,
endometrium, the local and peripheral immune systems and clinical data into a cross-tissue predictive model of
disease classification. Our integrated approach will leverage hundreds of existing, clinically well-annotated
biospecimens in our well established Human Endometrial Tissue & DNA Bank and ongoing accrual through our
extensive network of physician and surgeon collaborators. The impact of this study will be to derive a replete
transcriptomic and proteomic taxonomy of endometriosis lesions, their niche environments, eutopic endometrium,
and the local and peripheral immune systems at single cell resolution; identify disease subtypes based on
molecular signatures for disease stratification and inform personalized diagnostic and therapeutic targets; and
provide a rich data source for the greater research community focused on endometriosis and related disorders.

子宫内膜,局部和外周免疫系统和临床数据到一个跨组织的预测模型,
疾病分类我们的综合方法将利用数百个现有的、临床上注释良好的
我们完善的人类子宫内膜组织和DNA库中的生物标本,并通过我们的
广泛的医生和外科医生合作者网络。这项研究的影响将是得出一个充满
子宫内膜异位症病变的转录组学和蛋白质组学分类,它们的生态位环境,在位子宫内膜,
以及单细胞分辨率的局部和外周免疫系统;基于
