Cebp1 and Cebpβ transcriptional axis controls eosinophilopoiesis in zebrafish [bulkRNA-Seq]

ABSTRACT: Eosinophils are well known to regulate host protection from parasites and have been reported to paticipate many other physiologic and pathologic processes. Understanding the role of eosinophils in these processes requires a better understanding of eosinophilopoiesis. Using a zebrafish model, we have identified an eosinophil lineage-specific marker, eslec. Using this marker we have established a Tg(eslec:eGFP) reporter line, which specifically labels zebrafish eosinophil lineage cells from early life through adulthood. Spatial-temporal analysis of eslec+ cells demonstrated organ distribution at the larval stage. By single-cell RNA-Seq of eslec+ cells, tissue-distributed eosinophils were found to have similar differentiation paths but different tissue-specific expression profiles. Genetic analysis demonstrated a Cebp1 and Cebpβ transcriptional axis that regulated eosinophilopoiesis, in which Cebp1 directly targeted cebpb to inhibit eosinophil differentiationthe commitment, differentiation, and maturation of the eosinophil lineage. In summary, this study characterized eosinophil development in multiple dimensions including spatial-temporal patterns, expression profiles, and genetic regulators. The results provide for a better understanding of eosinophilopoiesis.

Metastasis-entrained eosinophils enhance lymphocyte-mediated anti-tumor immunity

Project description:The recognition of the immune system as a key component of the tumor microenvironment (TME) led to promising therapeutics. Since such therapies benefit only subsets of patients, understanding the activities of immune cells in the TME is required. Eosinophils are an integral part of the TME especially in mucosal tumors. Nonetheless, their role in the TME and the environmental cues that direct their activities are largely unknown, especially in metastasis. We report that breast cancer-driven lung metastasis is characterized by resident and recruited eosinophils. Eosinophil recruitment to the metastatic lung was regulated by G protein coupled receptor signaling but independent of CCR3. Functionally, eosinophils promoted lymphocyte-mediated anti tumor immunity. Transcriptome and proteomic analyses identified the TME rather than intrinsic differences between eosinophil subsets as a key instructing factor directing anti tumorigenic eosinophil activities. Specifically, TNF-a/IFN-g-activated eosinophils facilitated CD4+ and CD8+ T cell infiltration and promoted anti-tumor immunity. Collectively, we identify a mechanism by which the TME entrains eosinophils to adopt anti-tumorigenic properties, which may lead to the development of eosinophil-targeted therapeutics.

Transcriptional profiling of eosinophil subsets in Interleukin-5 transgenic mice

Project description:Eosinophils are important in fighting parasitic infections and are implicated in the pathogenesis of asthma and allergy. Interleukin-5 (IL-5) is a critical regulator of eosinophil development, controlling proliferation, differentiation and maturation of the lineage. Mice that constitutively express IL-5 have more than 10 fold more eosinophils in the haematopoietic organs than their wild type counterparts. We have identified that much of this expansion is in a population of Siglec-F high eosinophils, which are rare in wild type mice. In this study we assessed transcription in myeloid progenitors, eosinophil precursors and Siglec-F medium and Siglec-F high eosinophils from IL-5 transgenic mice and in doing so have created a useful resource for eosinophil biologists. We have then utilised these populations to construct an eosinophil trajectory based on gene expression and to identify gene sets that are associated with eosinophil lineage progression. Cell cycle genes were significantly associated with the trajectory, and we experimentally demonstrate an increasing trend towards quiescence along the trajectory. Additionally we found gene expression changes associated with constitutive IL-5 signalling in eosinophil progenitors, many of which were not observed in eosinophils.

Gene expression analyses and distribution of H3K4me3 modification during eosinophil development (GMP to EoP to Eosinophil)

Project description:To identify regulators of homeostatic eosinophilopoiesis in mice, we took a global approach to identify genome-wide transcriptome and epigenome changes that occur during homeostasis at critical developmental stages, including eosinophil-lineage commitment (eosinophil progenitor [EoP] compared to granulocyte-monocyte progenitor [GMP]) and lineage maturation (eosinophil compared to EoP). Our analyses revealed markedly greater transcriptome alterations associated with eosinophil maturation (1199 genes) compared to eosinophil-lineage commitment (490 genes), highlighting the greater transcriptional investment necessary for differentiation. Our analyses also delineated a 976 gene eosinophil-lineage transcriptome that included a repertoire of 56 transcription factors, many of which have never previously been associated with eosinophils. Epigenomic studies revealed that genes that were specifically induced with eosinophil-lineage commitment in EoPs were “poised” with active chromatin marks in GMPs, despite not being expressed in GMPs. In contrast, a majority of the genes that were highly and specifically induced with maturation in eosinophils was not associated with poised chromatin, suggesting distinct epigenetic regulation between genes induced with lineage commitment compared to genes induced with cell maturation during eosinophil development.

Genome-wide expression analysis in Control and Atg5-deficient eosinophils.

Project description:Depletion of autophagy-associated protein 5 (Atg5), specifically within the eosinophil lineage in mice, resulted in increased body weight, impaired glucose metabolism, and structural alterations in adipose tissue. Our findings highlight that Atg5 influences the functional activity of eosinophils within adipose tissue rather than their quantity. To gain a deeper understanding of the molecular mechanisms underlying ATG5's role in eosinophils, we conducted total RNA-seq analyses on control and Atg5-deficient eosinophils isolated from both bone marrow and blood of mice.

Differential expression of Triggering Receptor Expressed on Myeloid Cells (Trem)-2 in tissue eosinophils

Project description:No longer regarded as simply end-stage cytotoxic effectors, eosinophils are now recognized as complex cells with unique phenotypes that develop in response to the local microenvironment. In our previous study, we documented eosinophil infiltration in association with characteristic muscle damage in the dystrophin-deficient (mdx) mouse model of Duchenne muscular dystrophy. In this earlier study, we found that eosinophils did not promote formation of muscle lesions, as these persisted in eosinophil-deficient mdx.PHIL mice. To obtain additional insight into these findings, we performed RNA sequencing on eosinophils isolated from muscle tissue of mdx, IL5tg, and mdx.IL5tg mouse strains. We discovered profound up-regulation of classical eosinophil effector proteins (major basic protein-1, eosinophil peroxidase, and eosinophil-associated ribonucleases, or RNases) in eosinophils isolated from lesion-free muscle from IL5tg mice. By contrast, we observed significant upregulation of tissue remodeling genes, including proteases, extracellular matrix components, collagen, and skeletal muscle precursors, as well as the immunomodulatory receptor, TREM2, in eosinophils isolated from skeletal muscle tissue from the dystrophin-deficient mdx mouse strain. The anti-inflammatory properties of TREM2 have been described in the monocyte/macrophage lineage; however, there are no previous studies documenting TREM2 expression in eosinophils. Here we show that TREM2 is critical for full growth and differentiation of bone marrow-derived eosinophil cultures and for full expression of toll-like receptor 4. Immunoreactive TREM2 was also detected on human eosinophils at levels that correlated with donor body mass index. Taken together, our findings provide important insight into the immunomodulatory and remodeling capacity of mouse eosinophils and the flexibility of their gene expression profiles in vivo.

Nutrient-derived signals regulate eosinophil adaptation to the small intestine

Project description:Eosinophils are commonly regarded as effector cells of type 2 immunity, yet they also accumulate in certain tissues during homeostasis - particularly in the gastrointestinal tract. Our understanding of the processes that govern homeostatic eosinophil accumulation and tissue-specific adaptation, and their functional significance, remains very limited. Here, we investigated how eosinophils adapt to the small intestine microenvironment and the local signals that regulate this process. We observed that eosinophils gradually migrate up the crypt-villus axis, giving rise to a villus-resident subpopulation with a distinct transcriptional signature. Genetic deficiency of eosinophils resulted in a reduction of villus area, as well as a reduction of multiple other immune cell populations, demonstrating their diverse functions in this environment. We determined that retinoic acid receptor signaling is specifically required for the maintenance of villus-resident eosinophils, while IL-5 is largely dispensable outside of its canonical role in eosinophil production. In addition, we unexpectedly found that high protein diet suppresses the accumulation of villus-resident eosinophils. Purified amino acids were sufficient for this effect, which was a consequence of accelerated eosinophil turnover within the tissue microenvironment and not due to altered development in the bone marrow. Our study provides new insight into the process of eosinophil adaptation to the small intestine and its dependence on nutrient-derived signals.
