Proteomic profiling of human circulating endothelial cells in sepsis using nanoproteomics

ABSTRACT: Circulating endothelial cells (CECs) are shed from the vascular intima into the bloodstream during endothelial injury and serve as a minimally invasive indicator of vascular dysfunction in sepsis. In this study, we isolated CECs from peripheral blood samples of patients with sepsis and healthy donors using high-dimensional spectral flow cytometry (Hoechst⁺/7-AAD⁻/CD45⁻/CD34⁺/CD146⁺). Due to the extremely low abundance of CECs in circulation, a nanoproteomics workflow optimized for trace cellular protein profiling was applied.

Neutrophils restrain sepsis associated coagulopathy via extracellular vesicles carrying superoxide dismutase 2 in a murine model of lipopolysaccharide induced sepsis

Project description:Disseminated intravascular coagulation (DIC) is a deadly complication of sepsis lacking effective managements. Although excessive inflammatory responses are emerging as key triggers of coagulopathy in sepsis, the interplays between immune system and coagulation are not fully understood. In a murine model of sepsis induced by intraperitoneal lipopolysaccharide (LPS), we found neutrophils in circulation mitigate the occurrence of DIC, thereby preventing the subsequent septic death. We found circulating neutrophils constantly release extracellular vesicles (EVs) containing mitochondria, which carry substantial amount of Superoxide Dismutase 2 (Sod2) upon LPS exposure. The extracellular Sod2 is necessary to bring about neutrophils’ antithrombotic function by eliminating endothelial reactive oxygen species (ROS) accumulation and alleviating endothelial dysfunction. Intervening endothelial ROS accumulation by antioxidants significantly ameliorates DIC with correspondingly improved survival in sepsis. These findings revealed a novel interaction between neutrophils and vascular endothelium which critically regulates coagulation in sepsis and had potential implications for the management of septic DIC.

Proteomic atlas of organ vasculopathies triggered by Staphylococcus aureus sepsis

Project description:Sepsis is a life-threatening condition triggered by a dysregulated host response to microbial infection resulting in vascular dysfunction, organ failure and death. Here we provide a semi-quantitative atlas of the murine vascular cell-surface proteome at the organ level, and how it changes during sepsis. Using in-vivo chemical labeling, multi-dimensional liquid chromatography, and high-resolution mass spectrometry, we demonstrate the presence of a vascular proteome that is perfusable and shared across multiple organs. This proteome was enriched in membrane-anchored proteins, including multiple regulators of endothelial barrier functions and the innate immunity. Further, we automated our workflows and applied them to a murine model of methicillin-resistant Staphylococcus aureus sepsis to unravel changes during systemic inflammatory responses. We provide an organ-specific atlas of both systemic and local changes of the vascular proteome triggered by sepsis. The data indicates that upon a septic challenge, the different organ vasculatures undergo unique and extensive remodeling.

Regulation of circulating mannosylated proteome by macrophage mannose receptor, Mrc1

Project description:Abundance of secreted proteins is tightly regulated in circulation, and its dysregulation forms a basis for development of pathology. N-glycosylation has been shown to be a decisive factor in determining the half-life of these proteins. Exoglycosidases remodel the proteins and exposure of cryptic ligands of endocytic lectin receptors determine their half-lives. We have devised a strategy for non-denaturing enrichment of these mannosylated proteins upon Mrc1 lectin receptor deficiency. Data-independent acquisition mass spectrometry was used to quantify these proteins post-enrichment by mannose-binding lectin (Concanavalin A). We find ligand profile of Mrc1 comprises of over 200 proteins, linking inflammation, organ dysfunction and sepsis to turnover of mannosylated blood proteome. Mannosylated proteome was profiled in mouse plasma upon Mrc1 knock-out and in human plasma upon sepsis. Pathway enrichment was performed to draw parallels between Mrc1 deficiency in mice and sepsis in human.

In Vivo Endothelial Cell Heterogeneity

Project description:Endothelial cells from nine steady state tissues and two regenerating tissues (bone marrow and liver) were intravitally labeld, isolated via flow sorting, and immediately processed for RNA extraction. When of sufficient quality, the RNA was amplified and hybridized. For comparison, Human Emybryonic Stem Cell-derived Endothelial cells (hESC-ECs) were differentiated and isolated based on similarities to the adult mouse counterparts. Endothelial cells were labeled via intravitally labeling of the vascular bed 8 minutes prior to sacrifice with minimally three markers to identify endothelial cells followed by flow sorting.

Transcription profiling of CD146 immunomagnetically enriched circulating endothelial cells (CECs) from healthy donors and patients with metastatic breast, colorectal, prostate, lung and renal cancer

Project description:Increased numbers of endothelial cells are observed in peripheral blood of cancer patients. These circulating endothelial cells (CECs) may contribute to the formation of blood vessels in the tumor or reflect vascular damage caused by treatment or tumor growth. Characterization of these cells may aid in the understanding of the angiogenic process and may provide biomarkers for treatment efficacy of angiogenesis inhibitors. To identify markers typical for CECs in cancer patients we assessed global gene expression profiles of CD146 immunomagnetically enriched CECs from healthy donors and patients with metastatic breast, colorectal, prostate, lung and renal cancer.

Construction of functional tissue-engineered microvasculatures by using circulating fibrocytes as mural cells

Project description:Mural cells are essential to the proper function of microvasculatures. However, the feasible cell source for mural cells has not been found, which is one of the key obstacles facedin tissue engineering. Our data show that circulating fibrocytes (CFs) sheathed and stabilized the microvasculatures formed by vascular endothelial cells (VECs) in collagen gel, formed gap junctions with VECs, and induced formation of basement membrane. When transplanted into nude mice with VECs either in collagen gel or Matrigel, CFs sheathed the microvasculatures formed by VECs, induced basal membrane formation and the microvasculatures connected to the host circulation. Human brain pericytes (HBPCs) had similar function to CFs, but HBPCs often mosaic into the lumen of capillary-like structures, actively proliferate, and have lower capacity of endocytosis and migration. Based on these data, we concluded thatCFs can be used as the cell source for mural cells to generate tissue-engineered microvasculatures

Expression data from adult mice pulmonary endothelial cells

Project description:Sepsis patients are at increased risk for hospital-acquired pulmonary infections, potentially due to post-septic immunosuppression known as the compensatory anti-inflammatory response syndrome (CARS). CARS has been attributed to leukocyte dysfunction, with an unclear role for endothelial cells. The pulmonary circulation is lined by an endothelial glycocalyx, a heparan sulfate-rich layer essential to pulmonary homeostasis. Heparan sulfate degradation occurs early in sepsis, leading to lung injury. Endothelial synthesis of new heparan sulfates subsequently allows for glycocalyx reconstitution and endothelial recovery. We hypothesized that remodeling of the reconstituted endothelial glycocalyx, mediated by alterations in the endothelial machinery responsible for heparan sulfate synthesis, contributes to CARS. Our experimental animal model of CARS recapitulated post-septic immunosuppression, coincidentally with structural remodeling of endothelial glycocalyx heparan sulfate. We used microarray to identify which heparan sulfate modifying enzyme is responsible for the remodeling of post-septic reconstituted glycocalyx, characterized with enrichment of heparan sulfate disaccharides sulfated at the 6-O position of glucosamine.

Vascular proteome responses precede organ dysfunction in a murine model of Staphylococcus aureus bacteremia

Project description:Vascular dysfunction and organ failure are two distinct, albeit highly interconnected clinical outcomes linked to morbidity and mortality in human sepsis. The mechanisms driving vascular and parenchymal damage are dynamic and display significant molecular crosstalk between organs and tissues. Therefore, assessing their individual contribution to disease progression is technically challenging. Here, we hypothesize that dysregulated vascular responses predispose the organism to organ failure. To address this hypothesis, we have evaluated four major organs in a murine model of S. aureus sepsis by combining in vivo labeling of the endothelial proteome, data-independent acquisition (DIA) mass spectrometry, and an integrative computational pipeline. The data reveal, with unprecedented depth and throughput, that a septic insult evokes organ-specific proteome responses that are highly compartmentalized, synchronously coordinated, and significantly correlated with the progression of the disease. This includes abundant vascular shedding, dysregulation of the intrinsic pathway of coagulation, compartmentalization of the acute phase-response, and abundant upregulation of glycocalyx components. Vascular proteome changes were also found to precede bacterial invasion and leukocyte infiltration into the organs, as well as to precede changes in various well-established cellular and biochemical correlates of systemic coagulopathy and tissue dysfunction. Importantly, our data suggests a potential role for the vascular proteome as a determinant of the susceptibility of the organs to undergo failure during sepsis.
