Abstract
Invariant natural killer T (iNKT) cells are innate-like T lymphocytes that express an invariant T cell receptor α chain and contribute to bridging innate and acquired immunity with rapid production of large amounts of cytokines after stimulation. Among effecter subsets of iNKT cells, follicular helper NKT (NKTFH) cells are specialized to help B cells. However, the mechanisms of NKTFH cell differentiation remain to be elucidated. In this report, we studied the mechanism of NKTFH cell differentiation induced by pneumococcal surface protein A and α-galactosylceramide (P/A) vaccination. We found that Gr-1+ cells helped iNKT cell proliferation and NKTFH cell differentiation in the spleen by producing interleukin-27 (IL-27) in the early phase after vaccination. The neutralization of IL-27 impaired NKTFH cell differentiation, which resulted in compromised antibody production and diminished protection against Streptococcus pneumoniae infection by the P/A vaccine. Our data indicated that Gr-1+ cell-derived IL-27 stimulated mitochondrial metabolism, meeting the energic demand required for iNKT cells to differentiate into NKTFH cells. Interestingly, Gr-1+ cell-derived IL-27 was induced by iNKT cells via interferon-γ production. Collectively, our findings suggest that optimizing the metabolism of iNKT cells was essential for acquiring specific effector functions, and they provide beneficial knowledge on iNKT cell-mediated vaccination-mediated therapeutic strategies.

Abstract
Despite the importance of IL-23 in mucosal host defense and disease pathogenesis, the mechanisms regulating the development of IL-23-producing mononuclear phagocytes remain poorly understood. Here, we employed an Il23aVenus reporter strain to investigate the developmental identity and functional regulation of IL-23-producing cells. We showed that flagellin stimulation or Citrobacter rodentium infection led to robust induction of IL-23-producing EpCAM+ DCIR2+ CD103- cDC2s, termed cDCIL23, which was confined to gut-associated lymphoid tissues, including the mesenteric lymph nodes, cryptopatches, and isolated lymphoid follicles. Furthermore, we demonstrated that Notch2 signaling was crucial for the development of EpCAM+ DCIR2+ cDC2s, and the combination of Notch2 signaling with retinoic acid signaling controlled their terminal differentiation into cDCIL23, supporting a two-step model for the development of gut cDCIL23. Our findings provide fundamental insights into the developmental pathways and cellular dynamics of IL-23-producing cDC2s at steady state and during pathogen infection.

Abstract
Natural killer (NK) cells are innate immune cells critical for protective immune responses against infection and cancer. Although NK cells differentiate in the bone marrow (BM) in an interleukin-15 (IL-15)-dependent manner, the cellular source of IL-15 remains elusive. Using NK cell reporter mice, we show that NK cells are localized in the BM in scattered and clustered manners. NK cell clusters overlap with monocyte and dendritic cell accumulations, whereas scattered NK cells require CXCR4 signaling. Using cell-specific IL-15-deficient mice, we show that hematopoietic cells, but not stromal cells, support NK cell development in the BM through IL-15. In particular, IL-15 produced by monocytes and dendritic cells appears to contribute to NK cell development. These results demonstrate that hematopoietic cells are the IL-15 niche for NK cell development in the BM and that BM NK cells are present in scattered and clustered compartments by different mechanisms, suggesting their distinct functions in the immune response.

Abstract
Emergency myelopoiesis (EM) is a hematopoietic response against systemic infections that quickly supplies innate immune cells. As lymphopoiesis is strongly suppressed during EM, the role of lymphocytes in that process has not received much attention. Here, we found that myeloid-like B cells (M-B cells), which express myeloid markers, emerge in the bone marrow (BM) after the induction of EM. M-B cells were mainly derived from pre-B cells and preferentially expressed IL-10, which directly stimulates hematopoietic progenitors to enhance their survival and myeloid-biased differentiation. Indeed, lacking IL-10 in B cells, blocking IL-10 in the BM with a neutralizing antibody, and deleting the IL-10 receptor in hematopoietic progenitors significantly suppressed EM, which failed to clear microbes in a cecal ligation and puncture model. Thus, a distinct B cell subset generated during infection plays a pivotal role in boosting EM, which suggests the on-demand reinforcement of EM by adaptive immune cells.

Abstract
Invariant natural killer T (iNKT) cells are a group of innate-like T lymphocytes that recognize lipid antigens. They are supposed to be tissue resident and important for systemic and local immune regulation. To investigate the heterogeneity of iNKT cells, we recharacterized iNKT cells in the thymus and peripheral tissues. iNKT cells in the thymus were divided into three subpopulations by the expression of the natural killer cell receptor CD244 and the chemokine receptor CXCR6 and designated as C0 (CD244
−
CXCR6
−
), C1 (CD244
−
CXCR6
+
), or C2 (CD244
+
CXCR6
+
) iNKT cells. The development and maturation of C2 iNKT cells from C0 iNKT cells strictly depended on IL-15 produced by thymic epithelial cells. C2 iNKT cells expressed high levels of IFN-γ and granzymes and exhibited more NK cell–like features, whereas C1 iNKT cells showed more T cell–like characteristics. C2 iNKT cells were influenced by the microbiome and aging and suppressed the expression of the autoimmune regulator AIRE in the thymus. In peripheral tissues, C2 iNKT cells were circulating that were distinct from conventional tissue-resident C1 iNKT cells. Functionally, C2 iNKT cells protected mice from the tumor metastasis of melanoma cells by enhancing antitumor immunity and promoted antiviral immune responses against influenza virus infection. Furthermore, we identified human CD244
+
CXCR6
+
iNKT cells with high cytotoxic properties as a counterpart of mouse C2 iNKT cells. Thus, this study reveals a circulating subset of iNKT cells with NK cell–like properties distinct from conventional tissue-resident iNKT cells.

Abstract
Dendritic cells (DCs) and monocytes are widely conserved immune cells in vertebrates that arise from hematopoietic stem cells via intermediate progenitors. The progenitors that strictly give rise to DCs or monocytes have been recently identified both in humans and in mice, thereby revealing their differentiation pathways. Advances in analysis technologies have further deepened our understanding of the development of DCs and monocytes from progenitor population-based to individual progenitor cell-based commitment. Since DC-committed progenitors, common DC progenitors (CDPs) and precursor conventional cDCs (pre-cDCs) do not differentiate into monocytes, DCs are a distinct lineage from monocytes, although monocytes can acquire DC-like functions upon activation at tissues where they arrive.

Abstract
BACKGROUND Epidemiologic studies have yielded conflicting results regarding the influence of a single bout of prolonged high-intensity exercise on viral infection. OBJECTIVE We sought to learn whether prolonged high-intensity exercise either exacerbates or ameliorates herpes simplex virus type 2 (HSV-2) infection according to the interval between virus exposure and exercise. METHODS Mice were intravaginally infected with HSV-2 and exposed to run on the treadmill. RESULTS Prolonged high-intensity exercise 17 hours after infection impaired the clearance of HSV-2, while exercise 8 hours after infection enhanced the clearance of HSV-2. These impaired or enhanced immune responses were related to a transient decrease or increase in the number of blood-circulating plasmacytoid dendritic cells. Exercise-induced glucocorticoids transiently decreased the number of circulating plasmacytoid dendritic cells by facilitating their homing to the bone marrow via the CXCL12-CXCR4 axis, which led to their subsequent increase in the blood. CONCLUSION A single bout of prolonged high-intensity exercise can be either deleterious or beneficial to antiviral immunity.

Abstract
As hematopoietic progenitors supply a large number of blood cells, therapeutic strategies targeting hematopoietic progenitors are potentially beneficial to eliminate unwanted blood cells, such as leukemic cells and immune cells causing diseases. However, due to their pluripotency, targeting those cells may impair the production of multiple cell lineages, leading to serious side effects such as anemia and increased susceptibility to infection. To minimize those side effects, it is important to identify monopotent progenitors that give rise to a particular cell lineage. Monocytes and monocyte-derived macrophages play important roles in the development of inflammatory diseases and tumors. Recently, we identified human monocyte-restricted progenitors, namely, common monocyte progenitors and pre-monocytes, both of which express high levels of CD64, a well-known monocyte marker. Here, we introduce a dimeric pyrrolobenzodiazepine (dPBD)-conjugated anti-CD64 antibody (anti-CD64-dPBD) that selectively induces the apoptosis of proliferating human monocyte-restricted progenitors but not non-proliferating mature monocytes. Treatment with anti-CD64-dPBD did not affect other types of hematopoietic cells including hematopoietic stem and progenitor cells, neutrophils, lymphocytes and platelets, suggesting that its off-target effects are negligible. In line with these findings, treatment with anti-CD64-dPBD directly killed proliferating monocytic leukemia cells and prevented monocytic leukemia cell generation from bone marrow progenitors of chronic myelomonocytic leukemia patients in a patient-derived xenograft model. Furthermore, by depleting the source of monocytes, treatment with anti-CD64-dPBD ultimately eliminated tumor-associated macrophages and significantly reduced tumor size in humanized mice bearing solid tumors. Given the selective action of anti-CD64-dPBD on proliferating monocyte progenitors and monocytic leukemia cells, it should be a promising tool to target cancers and other monocyte-related inflammatory disorders with minimal side effects on other cell lineages.

Abstract
The physiological stresses that diminish tissue stem-cell characteristics remain largely unknown. We previously reported that type I interferon (IFN), which is essential for host antiviral responses, is a physiological stressor for hematopoietic stem cells (HSCs) and small intestinal stem cells (ISCs) and that interferon regulatory factor-2 (IRF2), which attenuates IFN signaling, maintains their stemness. Here, using a dextran sodium sulfate (DSS)-induced colitis model, we explore the role of IRF2 in maintaining colonic epithelial stem cells (CoSCs). In mice with a conditional Irf2 deletion in the intestinal epithelium (hereafter Irf2ΔIEC mice), both the number and the organoid-forming potential of CoSCs were markedly reduced. Consistent with this finding, the ability of Irf2ΔIEC mice to regenerate colon epithelium after inducing colitis was severely impaired, independently of microbial dysbiosis. Mechanistically, CoSCs differentiated prematurely into transit-amplifying (TA) cells in Irf2ΔIEC mice, which might explain their low CoSC counts. A similar phenotype was induced in wild-type mice by repeated injections of low doses of poly(I:C), which induces type I IFN. Collectively, we demonstrated that chronic IFN signaling physiologically stresses CoSCs. This study provides new insight into the development of colitis and molecular mechanisms that maintain functional CoSCs throughout life.

Abstract
Intestinal stem cells (ISCs) are located at the crypt base and fine-tune the balance of their self-renewal and differentiation1,2, but the physiological mechanism involved in regulating that balance remains unknown. Here we describe a transcriptional regulator that preserves the stemness of ISCs by restricting their differentiation into secretory-cell lineages. Interferon regulatory factor 2 (IRF2) negatively regulates interferon signalling3, and mice completely lacking Irf24 or with a selective Irf2 deletion in their intestinal epithelial cells have significantly fewer crypt Lgr5hi ISCs than control mice. Although the integrity of intestinal epithelial cells was unimpaired at steady state in Irf2-deficient mice, regeneration of their intestinal epithelia after 5-fluorouracil-induced damage was severely impaired. Similarly, extended treatment with low-dose poly(I:C) or chronic infection of lymphocytic choriomeningitis virus clone 13 (LCMV C13)5 caused a functional decline of ISCs in wild-type mice. In contrast, massive accumulations of immature Paneth cells were found at the crypt base of Irf2-/- as well as LCMV C13-infected wild-type mice, indicating that excess interferon signalling directs ISCs towards a secretory-cell fate. Collectively, our findings indicate that regulated interferon signalling preserves ISC stemness by restricting secretory-cell differentiation.

Abstract
Monocytes are a widely conserved cell population in vertebrates with important roles in both inflammation and homeostasis. Under both settings, monocytes continuously arise from hematopoietic progenitors in the bone marrow and, on demand, migrate into tissues through the bloodstream. Monocytes are classified into three subsets-classical, intermediate and non-classical-based on their cell surface expression of CD14 and CD16 in humans and Ly6C, CX3CR1 and CCR2 in mice. In tissues, monocytes differentiate further into monocyte-derived macrophages and dendritic cells to mediate innate and adaptive immune responses and maintain tissue homeostasis. Recently, the progenitors that strictly give rise to monocytes were identified in both humans and mice, thereby revealing the monocyte differentiation pathways.

Abstract
Propolis possesses several immunological functions. We recently generated a conditional Ca2+ biosensor yellow cameleon (YC3.60) transgenic mouse line and established a
five-dimensional (5D) (x, y, z, time, and Ca2+ signaling) system for intravital imaging of lymphoid tissues, including Peyer’s patches (PPs). To assess the effects of propolis on
immune cells, we analyzed Ca2+ signaling in vitro and in vivo using CD11c-Cre/YC3.60flox transgenic mice, in which CD11c+
dendritic cells (DCs) specifically express YC3.60. We found that propolis induced Ca2+ signaling in DCs in the PPs. Intravital imaging of PPs also showed that an intraperitoneal
injection of propolis augmented Ca2+ signaling in CD11c+ cells, suggesting that propolis possesses immune-stimulating activity. Furthermore, CD11c+ cells in
PPs in mice administrated propolis indicated an increase in Ca2+ signaling. Our results indicate that propolis induces immunogenicity under physiological conditions.

Abstract
The intestinal mucosa is a physiological barrier for most microbes, including both commensal bacteria and invading pathogens. Under homeostatic conditions, immunoglobulin A (IgA) is the major immunoglobulin isotype in the intestinal mucosa. Microbes stimulate the production of IgA, which controls bacterial translocation and neutralizes bacterial toxins at the intestinal mucosal surface. In the intestinal mucosa, dendritic cells (DCs), specialized antigen-presenting cells, regulate both T-cell-dependent (TD) and -independent (TI) immune responses. The intestinal DCs are a heterogeneous population that includes unique subsets that induce IgA synthesis in B cells. The characteristics of intestinal DCs are strongly influenced by the microenvironment, including the presence of commensal bacterial metabolites and epithelial cell-derived soluble factors. In this review, we summarize the ontogeny, classification, and function of intestinal DCs and how the intestinal microenvironment conditions DCs and their precursors to become the mucosal phenotype, in particular to regulate IgA production, after they arrive at the intestine. Understanding the mechanism of IgA synthesis could provide insights for designing effective mucosal vaccines.

Abstract
The basic helix-loop-helix transcription factor E2-2 is essential for the development of plasmacytoid dendritic cells (pDCs) but not conventional DCs (cDCs). Here, we generated E2-2 reporter mice and demonstrated that an E2-2high fraction among common DC progenitors, which are a major source of pDCs and cDCs in the steady state, strictly gave rise to pDCs in the presence of Flt3 (Fms-like tyrosine kinase receptor-3) ligand ex vivo or in the secondary lymphoid organs when transferred in vivo. However, in the small intestine, some of these E2-2high progenitors differentiated into cDCs that produced retinoic acid. This transdifferentiation was driven by signaling via the common β receptor, a receptor for the cytokines IL-3, IL-5 and GM-CSF, which are abundant in the gut. In the presence of GM-CSF and Flt3 ligand, E2-2high-progenitor-derived cDCs consistently induced Foxp3+ Treg cells ex vivo. Our findings reveal the commitment and flexibility of E2-2high progenitor differentiation and imply that pertinent tuning machinery is present in the gut microenvironment.

Abstract
Monocytes give rise to macrophages and dendritic cells (DCs) under steady-state and inflammatory conditions, thereby contributing to host defense and tissue pathology. Inflammation triggers the differentiation of tissue-infiltrating monocytes into monocyte-derived macrophages and DCs, which are associated with homeostatic host defense reactions and inflammatory diseases. In mice, monocytes are divided into classical Ly6chi- and non-classical Ly6clo-expressing subsets. Ly6clo monocytes are present only in the blood; however, Ly6chi monocytes are found in blood and other tissues (wherein they differentiate into macrophages and DCs). In this context, most Ly6clo monocytes are derived from Ly6chi monocytes. In humans, monocytes comprise major CD14+CD16- and other CD14+CD16+ and CD14loCD16+ monocytes. A monocyte lineage-restricted common monocyte progenitor (cMoP) was previously identified in mice; herein, we introduce human cMoP, which was identified as a CLEC12AhiCD64hi subpopulation of conventional granulocyte-monocyte progenitors (cGMPs) in umbilical cord blood and bone marrow. The human cMoP produced monocyte subsets without showing any potential of differentiating into myeloid or lymphoid cells ex vivo. Within the cGMP population, we also identified revised GMPs that completely lacked DC and lymphoid potential, which sequentially produced cMoPs, pre-monocytes, and monocytes. Collectively, our findings enhance the current understanding of human myeloid cell differentiation pathways.

Abstract
Abstract
2′-5′-oligoadenylate synthase 1 (OAS1) is one of the interferon-stimulated genes (ISG) which plays a critical role in innate anti-viral immunity. Stimulated by viral double strand RNA (dsRNA), OAS1 produces 2′-5′ linked oligomer of adenylates (2′-5′A) and the produced 2′-5′A activates ribonuclease-L (RNase-L) which results in degradation of viral RNA and inhibition of viral replications.
We identified autosomal inherited OAS1 missense mutations in three Japanese pedigrees with infantile-onset primary alveolar proteinosis with hypogammaglobulinemia. Patients’ peripheral blood monocytes and CD11c+ myeloid dendritic cells (mDC) were progressively decreased; CD27+ memory B cells were lacking. The alveolar macrophages showed decreased phagocytosis activity; and the enlarged and foamy form was scarcely observed, which were typical in conventional pulmonary alveolar proteinosis (PAP). Their bone marrow monocyte progenitors were decreased and showed reduced colony forming potentials. One of the patients is currently alive without PAP after hematopoietic stem cell transplantation.
The recombinant mutant OAS1 protein had unaltered dsRNA binding activity. Patient-derived lymphoblastoid cell lines showed normal expression of OAS1 protein and mRNA, and unaltered function in OAS1 - RNase-L pathway. We generated model OAS1 knock-in mice by CRISPR/Cas9 based gene editing and analyzed immune-phenotypes. The mice show normal B and DC numbers and normal serum immunoglobulin levels so far. Detailed functional study on mutant OAS1 protein with the multi-Omics approach is currently underway.

Abstract
Colonic macrophages induce pathogenic inflammation against commensal bacteria, leading to inflammatory bowel disease (IBD). Although the ontogeny of colonic macrophages has been well studied in the past decade, how macrophages gain colitogenic properties during the development of colitis is unknown. Using a chemically induced colitis model, we showed that accumulated Ly6C+ cells consisting of inflammatory monocytes and inflammatory macrophages strongly expressed representative colitogenic mediators such as tumor necrosis factor-α (TNF-α) and inducible nitric oxide synthase (iNOS). The interferon-γ-signal transducer and activator of transcription 1 (IFN-γ-Stat1) pathway was required for generating colitogenic macrophages, given that Stat1-/- mice had less severe colitis and fewer colitogenic macrophages. Notably, IFN-γ induced histone acetylation at the promoter regions of the Tnf and Nos2 loci in the monocyte and macrophage lineage, indicating that IFN-γ-dependent epigenetic regulation instructs the development of the colitogenic monocyte and macrophage lineage in vivo. Collectively, our results provide the essential mechanism by which dysregulated colitogenic monocytes/macrophages develop at the colon mucosa during inflammation, and suggest a new drug target for treating IBD.

Abstract
Mast cells are classically thought to play an important role in protection against helminth infections and in the induction of allergic diseases; however, recent studies indicate that these cells also contribute to neovascularization, which is critical for tissue remodeling, chronic inflammation, and carcinogenesis. Here, we demonstrate that mast cells are essential for sprouting angiogenesis in a murine model of oxygen-induced retinopathy (OIR). Although mouse strains lacking mast cells did not exhibit retinal neovascularization following hypoxia, these mice developed OIR following infusion of mast cells or after injection of mast cell tryptase (MCT). Relative hypoxia stimulated mast cell degranulation via transient receptor potential ankyrin 1. Subsequent surges in MCT stimulated retinal endothelial cells to produce monocyte chemotactic protein-1 (MCP1) and angiogenic factors, leading to sprouting angiogenesis. Mast cell stabilizers as well as specific tryptase and MCP1 inhibitors prevented the development of OIR in WT mice. Preterm infants with early retinopathy of prematurity had markedly higher plasma MCT levels than age-matched infants without disease, suggesting mast cells contribute to human disease. Together, these results suggest therapies that suppress mast cell activity should be further explored as a potential option for preventing eye diseases and subsequent blindness induced by neovascularization.

Abstract
Interleukin 27 (IL-27) has been identified as a potent cytokine in the differentiation of type 1 regulatory T (Tr1) cells through interactions with several key elements, including transcription factors such as aryl hydrocarbon receptor and IL-21. Autocrine production of IL-21 is known to be important for maintaining IL-10 expression by Tr1 cells. Although previous studies have shown that the phosphoinositide 3-kinase (PI3K) -Akt axis contributes to the differentiation of helper T-cell subsets, the role of the PI3K pathway on Tr1 cell differentiation remains to be elucidated. Here, we demonstrate that suppression of the PI3K-Akt pathway results in impairment of IL-27-induced Tr1 (IL-27-Tr1) cell differentiation in vitro and in vivo. Furthermore, this suppression down-regulates IL-21 receptor expression by Tr1 cells, followed by suppression of IL-10 expression by IL-27-Tr1 cells. These results suggest that the PI3K pathway enhances IL-10 expression by IL-27-Tr1 cells through up-regulation of IL-21 receptors.

Abstract
Mucopolysaccharidosis type II (MPS II) is a lysosomal storage disease caused by the deficient activity of iduronate 2-sulfatase (IDS), which is involved in the lysosomal catabolism of the glycosaminoglycans (GAGs) dermatan and heparan sulfate. Such a deficiency leads to the accumulation of undegraded GAGs in some organs. Although enzyme replacement therapy is available as a treatment of MPS II, there are some limitations, such as the requirement of weekly administration for whole life. To avoid such limitations, hematopoietic cell transplantation (HSCT) is a possible alternative. In fact, some report suggested positive effects of HSCT for MPS II. However, HSCT has also some limitations. Strong conditioning regimens can cause severe side effects. For overcome this obstacle, we studied the efficacy of ACK2, an antibody that blocks KIT, followed by low-dose irradiation as a preconditioning regimen for HSCT using a murine model of MPS II. This protocol achieves 58.7±4.92% donor chimerism at 16weeks after transplantation in the peripheral blood of recipient mice. GAG levels were significantly reduced in liver, spleen, heart and intestine. These results indicated that ACK2-based preconditioning might be one of the choices for MPS II patients who receive HSCT.

Abstract
Dendritic cells (DCs) comprise two major subsets, conventional DC (cDC) and plasmacytoid DC (pDC) in the steady-state lymphoid organ. These cells have a short half-life and therefore, require continuous generation from hematopoietic stem cells and progenitor cells. Recently, we identified DC-restricted progenitors called common DC progenitors (CDPs) in the bone marrow of mouse. The CDPs can be isolated from mouse bone marrow based on the hematopoietic cytokine receptors, such as Flt3 (Fms-related tyrosine kinase 3) (CD135), c-kit (CD117), M-CSF (macrophage colony-stimulating factor) receptor (CD115), and IL-7 (interleukin-7) receptor-α (CD127). The CDPs comprise of two progenitors, CD115(+) CDPs and CD115(-) CDPs, and give rise to only DC subsets in both in vitro and in vivo. The former CDPs are the main source of cDC, while the later CDPs are the main source of pDC in vivo. Here, we provide a protocol for the isolation of dendritic cell progenitor and bone marrow progenitor cells from mouse.

Abstract
Hemophagocytic syndrome (HPS) is frequently associated with hematopoietic stem cell transplantation and is treated with some benefit derived from TNF-α inhibitors. However, the mechanisms of how HPS occurs and how a TNF-α inhibitor exerts some benefit to HPS management have remained unclear. We evaluated the effect of toll-like receptor (TLR) ligands, especially focusing on cytosine-phosphorothionate-guanine oligodeoxynucleotide (CpG), a TLR9 ligand, on HPS in mice that underwent transplantation with syngeneic or allogeneic bone marrow (BM) cells (Syn-BMT, Allo-BMT), or with allogeneic BM cells plus splenocytes to promote graft-versus-host disease (GVHD mice). Hemophagocytosis was a common feature early after all BMT, but it subsided in Syn-BMT and Allo-BMT mice. In GVHD mice, however, hemophagocytosis persisted and was accompanied by upregulated production of IFN-γ but not TNF-α, and it was suppressed by blockade of IFN-γ but not TNF-α. A single injection of the TLR9 ligand CpG promoted HPS in all BMT mice and was lethal in GVHD mice, accompanied by greatly upregulated production of TNF-α, IL-6, and IFN-γ. Blocking of TNF-α, but not IL-6 or IFN-γ, suppressed CpG-induced HPS in all BMT mice and rescued GVHD mice from CpG-induced mortality. Thus, TLR9 signaling mediates TNF-α-driven HPS in BMT mice and is effectively treated through TNF-α inhibition.

Abstract
Upon systemic bacterial infection, hematopoietic stem and progenitor cells (HSPCs) migrate to the periphery in order to supply a sufficient number of immune cells. Although pathogen-associated molecular patterns reportedly mediate HSPC activation, how HSPCs detect pathogen invasion in vivo remains elusive. Bacteria use the second messenger bis-(3'-5')-cyclic dimeric guanosine monophosphate (c-di-GMP) for a variety of activities. Here, we report that c-di-GMP comprehensively regulated both HSPCs and their niche cells through an innate immune sensor, STING, thereby inducing entry into the cell cycle and mobilization of HSPCs while decreasing the number and repopulation capacity of long-term hematopoietic stem cells. Furthermore, we show that type I interferon acted as a downstream target of c-di-GMP to inhibit HSPC expansion in the spleen, while transforming growth factor-β was required for c-di-GMP-dependent splenic HSPC expansion. Our results define machinery underlying the dynamic regulation of HSPCs and their niches during bacterial infection through c-di-GMP/STING signaling.

Abstract
The vitamin A (VA) metabolite retinoic acid (RA) affects the properties of T cells and dendritic cells (DCs). In VA-deficient mice, we observed that mesenteric lymph node (MLN)-DCs induce a distinct inflammatory T helper type 2 (Th2)-cell subset that particularly produces high levels of interleukin (IL)-13 and tumor necrosis factor-α (TNF-α). This subset expressed homing receptors for skin and inflammatory sites, and was mainly induced by B220(-)CD8α(-)CD11b(+)CD103(-) MLN-DCs in an IL-6- and OX40 ligand-dependent manner, whereas RA inhibited this induction. The corresponding MLN-DC subset of VA-sufficient mice induced a similar T-cell subset in the presence of RA receptor antagonists. IL-6 induced this subset differentiation from naive CD4(+) T cells upon activation with antibodies against CD3 and CD28. Transforming growth factor-β inhibited this induction, and reciprocally enhanced Th17 induction. Treatment with an agonistic anti-OX40 antibody and normal MLN-DCs enhanced the induction of general inflammatory Th2 cells. In VA-deficient mice, proximal colon epithelial cells produced TNF-α that may have enhanced OX40 ligand expression in MLN-DCs. The repeated oral administrations of a T cell-dependent antigen primed VA-deficient mice for IL-13-dependent strong immunoglobulin G1 (IgG1) responses and IgE responses that caused skin allergy. These results suggest that RA inhibits allergic responses to oral antigens by preventing MLN-DCs from inducing IL-13-producing inflammatory Th2 cells.

Abstract
Because immune responses simultaneously defend and injure the host, the immune system must be finely regulated to ensure the host's survival. Here, we have shown that when injected with high Toll-like receptor ligand doses or infected with lymphocytic choriomeningitis virus (LCMV) clone 13, which has a high viral turnover, inflammatory monocyte-derived dendritic cells (Mo-DCs) engulfed apoptotic erythroid cells. In this process, called hemophagocytosis, phosphatidylserine (PS) served as an "eat-me" signal. Type I interferons were necessary for both PS exposure on erythroid cells and the expression of PS receptors in the Mo-DCs. Importantly, hemophagocytosis was required for interleukin-10 (IL-10) production from Mo-DCs. Blocking hemophagocytosis or Mo-DC-derived IL-10 significantly increased cytotoxic T cell lymphocyte activity, tissue damage, and mortality in virus-infected hosts, suggesting that hemophagocytosis moderates immune responses to ensure the host's survival in vivo. This sheds light on the physiological relevance of hemophagocytosis in severe inflammatory and infectious diseases.

Abstract
All-trans-retinoic acid (RA) plays a critical role in maintaining immune homeostasis. Mouse intestinal CD103⁺ dendritic cells (DCs) produce a high level of RA by highly expressing retinal dehydrogenase (RALDH)2, an enzyme that converts retinal to RA, and induce gut-homing T cells. However, it has not been identified which subset of human DCs produce a high level of RA. In this study, we show that CD1c⁺ blood myeloid DCs (mDCs) but not CD141(high) mDCs or plasmacytoid DCs exhibited a high level of RALDH2 mRNA and aldehyde dehydrogenase (ALDH) activity in an RA- and p38-dependent manner when stimulated with 1α,25-dihydroxyvitamin D₃ (VD₃) in the presence of GM-CSF. The ALDH activity was abrogated by TLR ligands or TNF. CD103⁻ rather than CD103⁺ human mesenteric lymph node mDCs gained ALDH activity in response to VD₃. Furthermore, unlike in humans, mouse conventional DCs in the spleen and mesenteric lymph nodes gained ALDH activity in response to GM-CSF alone. RALDH2(high) CD1c⁺ mDCs stimulated naive CD4⁺ T cells to express gut-homing molecules and to produce Th2 cytokines in an RA-dependent manner. This study suggests that CD1c⁺ mDCs are a major human DC subset that produces RA in response to VD₃ in the steady state. The "vitamin D-CD1c⁺mDC-RA" axis may constitute an important immune component for maintaining tissue homeostasis in humans.

Abstract
RATIONALE Patients who developed acute respiratory distress syndrome (ARDS) after infection with severe respiratory viruses (e.g., severe acute respiratory syndrome-coronavirus, H5N1 avian influenza virus), exhibited unusually high levels of CXCL10, which belongs to the non-ELR (glutamic-leucine-arginine) CXC chemokine superfamily. CXCL10 may not be a bystander to the severe virus infection but may directly contribute to the pathogenesis of neutrophil-mediated, excessive pulmonary inflammation. OBJECTIVES We investigated the contribution of CXCL10 and its receptor CXCR3 axis to the pathogenesis of ARDS with nonviral and viral origins. METHODS We induced nonviral ARDS by acid aspiration and viral ARDS by intratracheal influenza virus infection in wild-type mice and mice deficient in CXCL10, CXCR3, IFNAR1 (IFN-α/β receptor 1), or TIR domain-containing adaptor inducing IFN-β (TRIF). MEASUREMENTS AND MAIN RESULTS We found that the mice lacking CXCL10 or CXCR3 demonstrated improved severity and survival of nonviral and viral ARDS, whereas mice that lack IFNAR1 did not control the severity of ARDS in vivo. The increased levels of CXCL10 in lungs with ARDS originate to a large extent from infiltrated pulmonary neutrophils, which express a unique CXCR3 receptor via TRIF. CXCL10-CXCR3 acts in an autocrine fashion on the oxidative burst and chemotaxis in the inflamed neutrophils, leading to fulminant pulmonary inflammation. CONCLUSIONS CXCL10-CXCR3 signaling appears to be a critical factor for the exacerbation of the pathology of ARDS. Thus, the CXCL10-CXCR3 axis could represent a prime therapeutic target in the treatment of the acute phase of ARDS of nonviral and viral origins.

Abstract
Toll-like receptor 3 (TLR3), retinoic acid-inducible gene I, and melanoma differentiation-associated antigen 5 (RIG-I/MDA-5) helicases are known to sense double-stranded RNA (dsRNA) virus and initiate antiviral responses, such as production of type-I interferons (IFNs). Recognition of dsRNA by TLR3 or RIG-I/MDA-5 is cell-type-dependent and recent studies have shown a direct link between TLRs and hematopoiesis. We hypothesized that viral dsRNA recognized by either TLR3 or RIG-I/MDA-5, affects the growth of human hematopoietic stem/progenitor cells. Here we show that polyinosinic polycytidylic acid (poly I:C)-mediated very rapid apoptosis occurs within 1 hour in CD34(+) cells in a dose-dependent manner. Polyadenylic-polyuridylic acid, another synthetic dsRNA that signals only through TLR3, had no effect. Poly I:C-LMW/LyoVec, a complex between low molecular-weight poly I:C and the transfection reagent LyoVec, which signals only through RIG-I/MDA-5, induces apoptosis of CD34(+) cells. A strong and sustained upregulation of messenger RNA and protein levels of Noxa, a proapoptotic BH3-only protein that can be induced by RIG-I/MDA-5 pathway, is found in CD34(+) cells treated by poly I:C. Although poly I:C upregulates type-I IFNs in CD34(+) cells, neither exogenous IFN-α nor IFN-β induces rapid apoptosis in CD34(+) cells and neutralization or blocking of type-I IFN receptor does not rescue CD34(+) cells, whereas Z-VAD, a pan-caspase inhibitor, rescues the cells from apoptosis. These results suggest that RIG-I/MDA-5, but not TLR3, signaling triggers poly I:C-induced rapid apoptosis of human CD34(+) cells, which will provide an insight into the mechanisms of dsRNA virus-mediated hematopoietic disorders.

Abstract
BACKGROUND & AIMS Pancreatic acinar cells are used to study regulated exocytosis. We investigated the role of interferon regulatory factor-2 (IRF2) in exocytosis in pancreatic acinar cells. METHODS Pancreas tissues from Irf2⁺/⁺, Irf2⁺/⁻), and Irf2⁻/⁻ mice were examined by microscopy, immunohistochemical, and immunoblot analyses; amylase secretion was quantified. We also compared salivary glands and pancreatic islets of Irf2⁻/⁻ mice with those of Irf2⁺/⁻ mice. To examine the effects of increased signaling by type I interferons, we studied pancreatic acini from Irf2⁻/⁻Ifnar1⁻/⁻ mice. The effect of IRF2 on amylase secretion was studied using an acinar cell line and a retroviral system. We studied expression of IRF2 in wild-type mice with cerulein-induced pancreatitis and changes in pancreatic tissue of Irf2⁻/⁻ mice, compared with those of Irf2⁺/⁻ mice. RESULTS Irf2⁻/⁻ pancreas was white and opaque; numerous and wide-spread zymogen granules were observed throughout the cytoplasm, along with lack of fusion between zymogen granules and the apical membrane, lack of secretagogue-stimulated amylase secretion, and low serum levels of amylase and elastase-1, indicating altered regulation of exocytosis. The expression pattern of soluble N-ethylmaleimide-sensitive factor attachment protein receptors changed significantly, specifically in pancreatic acini, and was not rescued by disruption of type I interferon signaling. Down-regulation of IRF2 decreased amylase secretion in an acinar cell line. In mice with pancreatitis, levels of IRF2 were reduced. Irf2⁻/⁻ acini were partially resistant to induction of pancreatitis. CONCLUSIONS IRF2 regulates exocytosis in pancreatic acinar cells; defects in this process might be involved in the early phases of acute pancreatitis.

Abstract
Although both conventional dendritic cells (cDCs) and plasmacytoid dendritic cells (pDCs) are present in the gut-associated lymphoid tissues (GALT), the roles of pDCs in the gut remain largely unknown. Here we show a critical role for pDCs in T cell-independent (TI) IgA production by B cells in the GALT. When pDCs of the mesenteric lymph nodes (MLNs) and Peyer's patches (PPs) (which are representative GALT) were cultured with naive B cells to induce TI IgA class switch recombination (CSR), IgA production was substantially higher than in cocultures of these cells with cDCs. IgA production was dependent on APRIL and BAFF production by pDCs. Importantly, pDC expression of APRIL and BAFF was dependent on stromal cell-derived type I IFN signaling under steady-state conditions. Our findings provide insight into the molecular basis of pDC conditioning to induce mucosal TI IgA production, which may lead to improvements in vaccination strategies and treatment for mucosal-related disorders.

Abstract
Mononuclear phagocytes such as dendritic cells (DCs) and macrophages in the lamina propria (LP) are thought to be important for both induction of inflammatory responses and maintenance of immunologic tolerance in the mammalian intestine. The molecular mechanisms by which these cells regulate intestinal immunity have remained poorly understood, however. Signal regulatory protein α (SIRPα) is a transmembrane protein that is specifically expressed in DCs, macrophages and neutrophils. Here, we show that SIRPα is abundant in CD11c(+) CD11b(+) LP cells of the mouse intestine. Whereas SIRPα did not appear to be important for the steady-state homeostasis of mucosal immunity in the intestine, the flagellin-stimulated production of IL-17 or interferon (IFN)-γ by LP cells of SIRPα mutant (MT) mice that lack the cytoplasmic region of the protein was markedly decreased compared with that observed with wild-type cells. Moreover, the flagellin-induced production of IL-6 by LP cells from SIRPα MT mice was also greatly reduced. SIRPα MT mice were also resistant to the development of colitis induced by IL-10 deficiency. Our data thus suggest that SIRPα expressed on CD11c(+) LP cells is important for the production of IL-17 or IFN-γ in the LP as well as for the development of colitis induced by IL-10 deficiency.

Abstract
Nucleotide oligomerization binding domain (Nod)-like receptors are critical cytosolic sensors for the recognition of bacterial peptidoglycan. However, their role in the induction of dendritic cell (DC)-mediated cross-priming remains unclear. In this study, we demonstrate that injecting ligands for Nod1 and Nod2 along with Ag into wild-type mice significantly enhanced the cross-priming of Ag-specific CD8+ T cells by CD8alpha+ DCs, as assessed from the expansion of IFN-gamma+ CD8+ T cells, CTL activity against Ag-pulsed targets, and the rejection of transplanted tumors expressing the cognate Ag. The enhancement of CD8alpha+ DC-mediated cross-priming was likely due to the upregulation of Ag cross-presentation and of costimulatory molecules. Our findings collectively indicate that Nod1/2 signaling is critical for the optimal induction of DC cross-priming in vivo, which may offer an alternative therapeutic pathway in cancer and hosts refractory to TLR signals or paralyzed by viral evasion strategy.

Abstract
PURPOSE It has been widely accepted that Th1- and IFN-gamma-mediated immune responses are indispensable for corneal allograft rejection in BALB/c hosts. The present study was designed to determine the role of IFN-gamma and IL-17 in the rejection by C57BL/6 hosts, which display high rejection rates. METHODS MHC-matched or -mismatched corneal allografts were grafted onto IFN-gamma-knockout (GKO), IFN-gamma-receptor-knockout (GRKO), IL-17-knockout (IL-17KO), or wild-type (WT) C57BL/6 hosts. Graft fates were assessed clinically and histologically. At appropriate time intervals after allografting, RNA was isolated from corneal graft parenchymal and stromal tissues and cervical lymph nodes. The cytokine mRNA levels of Th1, -2, and -17 type were analyzed by real-time PCR. RESULTS No significantly prolonged allograft survival was observed in any combinations. The rejected MHC-mismatched corneas in GKO elicited intensive infiltration of eosinophils, CD11b(+) macrophages, and B cells, but few Gr-1(+)CD11c(-) neutrophils. In contrast, rejected MHC-matched corneas in GKO hosts, as well as GRKO and WT hosts, elicited intensive infiltration of CD11b(+) macrophages and Gr-1(+)CD11c(-) neutrophils, but no B220(+) B cells and eosinophils. At 1 week after MHC-matched allografting, mRNA levels of IL-6 and IL-17A in the lymph node were extensively upregulated in GKO hosts. It is of interest that anti-IFN-gamma treatment did not improve the allograft survival in IL-17KO hosts. CONCLUSIONS IFN-gamma and IL-17 play no critical role in the development of minor-specific allograft rejection in C57BL/6 mice. This indicates the presence of sophisticated rejection mechanisms that are still elusive and cannot be ascribed simply to Th1, -2, or -17.

Abstract
To elucidate the mechanisms controlling peripheral tolerance, we established two transgenic (Tg) mouse strains expressing different levels of membrane-bound OVA (mOVA) as a skin-associated self-Ag. When we transferred autoreactive TCR-Tg CD8 T cells (OT-I cells), keratin 14 (K14)-mOVA(high) Tg mice developed autoreactive skin disease (graft-vs-host disease (GVHD)-like skin lesions) while K14-mOVA(low) Tg mice did not. OT-I cells in K14-mOVA(high) Tg mice were fully activated with full development of effector function. In contrast, OT-I cells in K14-mOVA(low) Tg mice proliferated but did not gain effector function. Exogenous IL-15 altered the functional status of OT-I cells and concomitantly induced disease in K14-mOVA(low) Tg mice. Conversely, neutralization of endogenous IL-15 activity in K14-mOVA(high) Tg mice attenuated GVHD-like skin lesions induced by OT-I cell transfer. Futhermore, K14-mOVA(high) Tg mice on IL-15 knockout or IL-15Ralpha knockout backgrounds did not develop skin lesions after adoptive transfer of OT-I cells. These results identify IL-15 as an indispensable costimulator that can determine the functional fate of autoreactive CD8 T cells and whether immunity or tolerance ensues, and they suggest that inhibition of IL-15 function may be efficacious in blocking expression of autoimmunity where a breach in peripheral tolerance is suspected.

Abstract
Leishmaniases are a major international public health problem, and macrophages are crucial for host resistance to this parasite. To determine if phosphatase and tensin homologue deleted on chromosome ten (Pten), a negative regulator of the PI3K pathway, plays a role in macrophage-mediated resistance to Leishmania, we generated C57BL/6 mice lacking Pten specifically in macrophages (LysMCrePten(flox/flox) mice). Examination of lesions resulting from Leishmania major infection showed that LysMCrePten(flox/flox) mice were more susceptible to the parasite than wild-type (WT) mice in the early phase of the infection, but were eventually able to eliminate the pathogen. In vitro Pten-deficient macrophages showed a reduced ability to kill parasites in response to IFN-gamma treatment, possibly because the mutant cells exhibited decreased TNF secretion that correlated with reductions in inducible nitric oxide synthase expression and nitric oxide production. In response to various TLR ligands, Pten-deficient macrophages produced less TNF and IL-12 but more IL-10 than WT cells. However, analysis of cells in the lymph nodes draining L. major inoculation sites indicated that both LysMCrePten(flox/flox) and WT mice developed normal Th1 responses following L. major infection, in line with the ability of LysMCrePten(flox/flox) mice to eventually eliminate the parasite. Our results indicate that the efficient clearance of intracellular parasites requires Pten in macrophages.

Abstract
The CD4(+)CD25(+)Foxp3(+) regulatory T cells (Treg) play an important role in the control of peripheral tolerance by directly inhibiting conventional T cell proliferative and effector functions. However, the mechanisms by which Treg regulate the homeostasis of lymph nodes remain unclear. In this study, we show in a mouse model that Treg control two major checkpoints dictated by the interaction between self-reactive CD4(+) T cells and resident dendritic cell (DC) in secondary lymphoid organs. First, Treg inhibit the production of CCR5 ligands, limiting the CCR5-dependent recruitment of DC in the lymph nodes. Second, Treg prevent the DC exposure of IL-15Ralpha, markedly interfering in the DC-mediated NK cell proliferation in vivo. Therefore, the DC/T cell autoreactivity leading to NK cell triggering could potentially be controlled by the coinhibition of both IL-15Ralpha and CCR5 in autoimmune disorders in which NK cells play a deleterious role.
