Multi-omic profiling of primary mouse neutrophils reveals a pattern of sex and age-related functional regulation

ABSTRACT: Neutrophils are the most abundant white blood cells in humans and constitute one of the first lines of defense in the innate immune response. Neutrophils are extremely short-lived cells, which survive less than a day after reaching terminal differentiation. Thus, little is known about how organismal aging, rather than the daily cellular aging process, may impact neutrophil biology. In addition, accumulating evidence suggests that both immunity and organismal aging are extremely sex-dimorphic. Here, we describe a multi-omic resource of mouse primary bone marrow neutrophils from young and old female and male animals, at the transcriptomic, metabolomic and lipidomic levels. Importantly, we identify widespread age-related and sex-dimorphic regulation of ‘omics’ in neutrophils, specifically regulation of chromatin metabolism. We leverage machine-learning and identify candidate molecular drivers of age-related and sex-dimorphic transcriptional regulation of neutrophils. We leverage our resource to predict increased levels/release of neutrophil elastase in male mice. To date, this dataset represents the largest multi-omic resource for the study of neutrophils across biological sex and ages. This resource identifies molecular states linked to neutrophil characteristics linked to organismal age or sex, which could be leveraged to improve immune responses across individuals.

Lipopolysaccharide-stimulated neutrophils

Project description:Neutrophil gene transcription following lipopolysaccharide exposure. Microarray analysis of lipopolysaccharide-treated human neutrophils. Neutrophils respond to infection by degranulation, release of reactive oxygen intermediates, and secretion of chemokines and cytokines; however, activation of neutrophil transcriptional machinery has been little appreciated. Recent findings suggest that gene expression may represent an additional neutrophil function after exposure to lipopolysaccharide (LPS). We performed microarray gene expression analysis of 4,608 mostly nonredundant genes on LPS-stimulated human neutrophils. Analysis of three donors indicated some variability but also a high degree of reproducibility in gene expression. Twenty-eight verifiable, distinct genes were induced by 4 h of LPS treatment, and 13 genes were repressed. Genes other than cytokines and chemokines are regulated; interestingly, genes involved in cell growth regulation and survival, transcriptional regulation, and interferon response are among those induced, whereas genes involved in cytoskeletal regulation are predominantly repressed. In addition, we identified monocyte chemoattractant protein-1 as a novel LPS-regulated chemokine in neutrophils. Included in these lists are five clones with no defined function. These data suggest molecular mechanisms by which neutrophils respond to infection and indicate that the transcriptional potential of neutrophils is greater than previously thought.

Expression data from control, aged and activated neutrophils in mouse blood

Project description:Neutrophils provide immune protection against pathogens but also may promote tissue injury in inflammatory diseases. Although neutrophils are generally considered as a relatively homogeneous population, evidence for heterogeneity is emerging. Under steady-state conditions, neutrophil heterogeneity may arise from ageing and the replenishment by newly released neutrophils from the bone marrow. We used microarray to globally analyze gene expression in aged neutrophils and characterize the inflammatory programs that are activated during the aging process in the circulation. Control, aged and activated neutrophils were sorted directly from mouse blood for RNA extraction and hybridization on Affymetrix microarrays. We transfused whole blood and harvested donor neutrophils marked by the CD45.1 allele 6h later to derive neutrophils that had truly aged in vivo. Sorted neutrophils were compared to control donor neutrophils that had been transferred for only 10 min. Additionally, we harvested circulating neutrophils from TNF-? treated mice for comparison with neutrophils activated by systemic inflammation.

Male sex affects type I/type II interferon response of neutrophils during hepatic Amebiasis

Project description:Hepatic amebiasis, a serious complication caused by the parasite Entamoeba histolytica, predominantly affects men. Earlier research in the murine disease model indicated that testosterone modulates an intense immune reaction, triggering destructive immunopathological changes in the liver. Inflammatory monocytes expressing proinflammatory chemokines, crucial for neutrophil recruitment, worsen this process. This study examines sex-related variances in neutrophils during hepatic amebiasis in a mouse model. Male subjects exhibited higher levels and recruitment of neutrophils compared to females. Androgens directly contributed to this bias, enhancing neutrophil recruitment and retarding maturation in response to infection. Transcriptomic analysis revealed diminished type I and II interferon-stimulated gene expression and reduced activation pathways in male neutrophils versus female neutrophils. Upon ex-vivo stimulation, female human neutrophils showed higher expression of a key type I interferon-stimulated gene (viperin/RSAD2) at the protein level, which was similar in mice after infection, and suppressed by testosterone. In male mice with hepatic amebiasis, sex-dependent factors led to recruitment of less active neutrophils, intensifying immunopathological damage to liver tissue. This sex disparity and testosterone's impact on interferon-stimulated genes hold implications beyond hepatic amebiasis, potentially influencing broader areas, including viral infectious diseases

Quantitative proteomics reveals tissue-specific, infection-induced and species-specific neutrophil protein signatures – mouse bone marrow, blood and peritoneal cavity neutrophils

Project description:Neutrophils are one of the first responders to infection and are a key component of the innate immune system through their ability to phagocytose and kill invading pathogens, secrete antimicrobial molecules and produce extracellular traps. Neutrophils are produced in the bone marrow, circulate within the blood and upon immune challenge migrate to the site of infection. We wanted to understand whether this transition shapes the mouse neutrophil protein landscape, how the mouse neutrophil proteome is impacted by systemic infection and perform a comparative analysis of human and mouse neutrophils. Using quantitative mass spectrometry we reveal tissue-specific, infection-induced and species-specific neutrophil protein signatures. We show a high degree of proteomic conservation between mouse bone marrow, blood and peritoneal neutrophils, but also identify key differences in the molecules that these cells express for sensing and responding to their environment. Systemic infection triggers a change in the bone marrow neutrophil population with considerable impact on the core machinery for protein synthesis and DNA replication along with environmental sensors. We also reveal profound differences in mouse and human blood neutrophils, particularly their granule contents and their receptor repertoires. Our proteomics data provides a valuable resource for understanding neutrophil function and phenotypes across species and model systems.

Transcriptome analysis of CD16/CD62L neutrophil subsets during human experimental endotoxemia

Project description:During systemic inflammation, different neutrophil subsets are mobilized to the blood circulation. These neutrophil subsets can be distinguished from normal circulating neutrophils (CD16bright/CD62Lbright) based on either an immature CD16dim/CD62Lbright or a CD16bright/CD62Ldim phenotype. Interestingly, the latter neutrophil subset is known to suppress lymphocyte proliferation ex vivo, but the underlying mechanism is largely unknown. We performed transcriptome analysis on the different neutrophil subsets to identify changes that are relevant for their functions. Neutrophil subsets were isolated by FACS sorting from the blood of healthy volunteers who were administered a single dose of lipopolysaccharide (LPS). The transcriptome was determined by microarray. The mobilized neutrophil subsets were characterized by specific transcriptome profiles reflecting their phase in neutrophil lifespan. Interestingly, the CD16bright/CD62Ldim suppressive neutrophils showed an interferon-induced transcriptome profile. This was confirmed by stimulation of peripheral neutrophils with IFNgamma. These cells acquired the capacity to suppress lymphocyte proliferation through the expression of programmed death ligand 1 (PD-L1). These data demonstrate that the suppressive phenotype of the neutrophil subset is induced by IFNgamma. Specific stimulation of neutrophils might have a pivotal role in regulating lymphocyte-mediated inflammation and autoimmune disease. After LPS infusion, blood was taken at t=0 and t=4 hours. Neutrophils were FACS sorted based on CD16 and CD62L expression. Gene expression of neutrophil subsets was assessed relative to t=0 as control.
