Abstract
Granulocyte-lineage cells are important innate immune effectors across all vertebrates. Named for conspicuous secretory granules, granulocytes have historically been studied for their antimicrobial roles. Although versions of these cells are found in all vertebrate species examined to date, disparate environmental and physiological pressures acting on distinct vertebrate classes have shaped many of the facets dictating granulocyte biology. Immune pressures further determine granulopoietic constraints, ultimately governing granulocyte functions. For amphibians that inhabit pathogen-rich aquatic environments for some or all their lives, their unique granulocyte biologies satisfy many of their antimicrobial needs. Amphibians also occupy an intermediate position in the evolution of vertebrate immune systems, using combinations of primitive (e.g., subcapsular liver) and more recently evolved (e.g., bone marrow) tissue sites for hematopoiesis and specifically, granulopoiesis. The last decade of research has revealed vertebrate granulocytes in general, and amphibian granulocytes in particular, are more complex than originally assumed. With dynamic leukocyte phenotypes, granulocyte-lineage cells are being acknowledged for their multifaceted roles beyond immunity in other physiological processes. Here we provide an overview of granulopoiesis in amphibians, highlight key differences in these processes compared to higher vertebrates, and identify open questions.

Abstract
Despite extensive research, there is still no treatment that would lead to remission in all patients with rheumatoid arthritis as our understanding of the affected site, the synovium, is still incomplete. Recently, single-cell technologies helped to decipher the cellular heterogeneity of the synovium; however, certain synovial cell populations, such as endothelial cells or peripheral neurons, remain to be profiled on a single-cell level. Furthermore, associations between certain cellular states and inflammation were found; whether these cells cause the inflammation remains to be answered. Similarly, cellular zonation and interactions between individual effectors in the synovium are yet to be fully determined. A deeper understanding of cell signalling and interactions in the synovium is crucial for a better design of therapeutics with the goal of complete remission in all patients.

Abstract
Host resistance to Mycobacterium tuberculosis (Mtb) infection requires the activities of multiple leukocyte subsets, yet the roles of the different innate effector cells during tuberculosis are incompletely understood. Here we uncover an unexpected association between eosinophils and Mtb infection. In humans, eosinophils are decreased in the blood but enriched in resected human tuberculosis lung lesions and autopsy granulomas. An influx of eosinophils is also evident in infected zebrafish, mice, and nonhuman primate granulomas, where they are functionally activated and degranulate. Importantly, using complementary genetic models of eosinophil deficiency, we demonstrate that in mice, eosinophils are required for optimal pulmonary bacterial control and host survival after Mtb infection. Collectively, our findings uncover an unexpected recruitment of eosinophils to the infected lung tissue and a protective role for these cells in the control of Mtb infection in mice.

Abstract
The differentiation of distinct leukocyte subsets is governed by lineage-specific growth factors that elicit disparate expression of transcription factors and markers by the developing cell populations. For example, macrophages (Mφs) and granulocytes (Grns) arise from common granulocyte-macrophage progenitors in response to distinct myeloid growth factors. In turn, myelopoiesis of the Xenopus laevis anuran amphibian appears to be unique to other studied vertebrates in several respects while the functional differentiation of amphibian Mφs and Grns from their progenitor cells remains poorly understood. Notably, the expression of colony stimulating factor-1 receptor (CSF-1R) or CSF-3R on granulocyte-macrophage progenitors marks their commitment to Mφ- or Grn-lineages, respectively. CSF-1R is activated by the colony stimulating factor-1 (CSF-1) and interleukin (IL-34) cytokines, resulting in morphologically and functionally distinct Mφ cell types. Conversely, CSF-3R is ligated by CSF-3 in a process indispensable for granulopoiesis. Presently, we explore the relationships between X. laevis CSF-1-Mφs, IL-34-Mφs and CSF-3-Grns by examining their expression of key lineage-specific transcription factor and myeloid marker genes as well as their enzymology. Our findings suggest that while the CSF-1- and IL-34-Mφs share some commonalities, the IL-34-Mφs possess transcriptional patterns more akin to the CSF-3-Grns. IL-34-Mφs also possess robust expression of dendritic cell-associated transcription factors and surface marker genes, further underlining the difference between this cell type and the CSF-1-derived frog Mφ subset. Moreover, the three myeloid populations differ in their respective tartrate-resistant acid phosphatase, specific- and non-specific esterase activity. Together, this work grants new insights into the developmental relatedness of these three frog myeloid subsets.

Abstract
Over the years of evolution, thousands of different animal species have evolved. All these species require an immune system to defend themselves against invading pathogens. Nevertheless, the immune systems of different species are obviously counteracting against the same pathogen with different efficiency. Therefore, the question arises if the process that was leading to the clades of vertebrates in the animal kingdom-namely mammals, birds, amphibians, reptiles, and fish-was also leading to different functions of immune cells. One cell type of the innate immune system that is transmigrating as first line of defense in infected tissue and counteracts against pathogens is the neutrophil granulocyte. During the host-pathogen interaction they can undergo phagocytosis, apoptosis, degranulation, and form neutrophil extracellular traps (NETs). In this review, we summarize a wide spectrum of information about neutrophils in humans and animals, with a focus on vertebrates. Special attention is kept on the development, morphology, composition, and functions of these cells, but also on dysfunctions and options for cell culture or storage.

Abstract
Retinoic acid-inducible gene I (RIG-I) is up-regulated during granulocytic differentiation of acute promyelocytic leukemia (APL) cells induced by all-trans retinoic acid (ATRA). It has been reported that RIG-I recognizes virus-specific 5'-ppp-double-stranded RNA (dsRNA) and activates the type I interferons signaling pathways in innate immunity. However, the functions of RIG-I in hematopoiesis remain unclear, especially regarding its possible interaction with endogenous RNAs and the associated pathways that could contribute to the cellular differentiation and maturation. Herein, we identified a number of RIG-I-binding endogenous RNAs in APL cells following ATRA treatment, including the tripartite motif-containing protein 25 (TRIM25) messenger RNA (mRNA). TRIM25 encodes the protein known as an E3 ligase for ubiquitin/interferon (IFN)-induced 15-kDa protein (ISG15) that is involved in RIG-I-mediated antiviral signaling. We show that RIG-I could bind TRIM25 mRNA via its helicase domain and C-terminal regulatory domain, enhancing the stability of TRIM25 transcripts. RIG-I could increase the transcriptional expression of TRIM25 by caspase recruitment domain (CARD) domain through an IFN-stimulated response element. In addition, RIG-I activated other key genes in the ISGylation pathway by activating signal transducer and activator of transcription 1 (STAT1), including the modifier ISG15 and several enzymes responsible for the conjugation of ISG15 to protein substrates. RIG-I cooperated with STAT1/2 and interferon regulatory factor 1 (IRF1) to promote the activation of the ISGylation pathway. The integrity of ISGylation in ATRA or RIG-I-induced cell differentiation was essential given that knockdown of TRIM25 or ISG15 resulted in significant inhibition of this process. Our results provide insight into the role of the RIG-I-TRIM25-ISGylation axis in myeloid differentiation.

Abstract
Psychological stress may be linked to cancer incidence; however, more direct evidence is required to support this viewpoint. In this study, we investigated the effects of stress on immunosurveillance against cancer cells using a previously established examination stress model. We showed that the cancer killing activity (CKA) of granulocytes (also known as polymorphic nuclear cells, PMNs) is sharply reduced during examination stress stimulation in some donors who are psychologically sensitive to examination stress, with the concentration of plasma stress hormones (cortisone, epinephrine, and norepinephrine) increasing accordingly. The effects of stress hormones on immune cell CKA were also investigated under two in vitro co-incubation conditions, with all three hormones found to exert inhibitory effects on the CKA of PMNs and mononuclear cells. We showed that stress triggered the release of stress hormones which had profound inhibitory effects on the innate anticancer functions of PMNs. These results provide a possible explanation for the relationship between psychological stress and cancer incidence.

Abstract
Acute myeloid leukemia (AML) is characterized by recurrent mutations that affect normal hematopoiesis. The analysis of human AMLs has mostly been performed using end-point materials, such as cell lines and patient derived AMLs that also carry additional contributing mutations. The molecular effects of a single oncogenic hit, such as expression of the AML associated oncoprotein AML1-ETO on hematopoietic development and transformation into a (pre-) leukemic state still needs further investigation. Here we describe the development and characterization of an induced pluripotent stem cell (iPSC) system that allows in vitro differentiation towards different mature myeloid cell types such as monocytes and granulocytes. During in vitro differentiation we expressed the AML1-ETO fusion protein and examined the effects of the oncoprotein on differentiation and the underlying alterations in the gene program at 8 different time points. Our analysis revealed that AML1-ETO as a single oncogenic hit in a non-mutated background blocks granulocytic differentiation, deregulates the gene program via altering the acetylome of the differentiating granulocytic cells, and induces t(8;21) AML associated leukemic characteristics. Together, these results reveal that inducible oncogene expression during in vitro differentiation of iPS cells provides a valuable platform for analysis of aberrant regulation in disease.

Abstract
In the parasitoid/polydnavirus/host system, polydnaviruses protect larva development in the host hemocoel by suppressing the host immune response. However, the negative effects on the parasitoid and the strategy of the parasitoid to deal with this disadvantage are still unknown. Microplitis bicoloratus bracovirus induces granulocyte apoptosis to suppress immune responses, resulting in an apoptotic haemolymph environment in which immature M. bicoloratus larva develop. Here, we determined the transcriptional profiles of immature M. bicoloratus across five time-points throughout the immature developmental process from egg to third instar. Dynamic gene expression pattern analysis revealed clear rapid changes in gene expression characteristic of each developmental stage, indicating faster sequential unambiguous functional division during development. Combined with the proteome of the host haemolymph, immature parasitoids likely secreted a Cu/Zn superoxide dismutase to reduce reactive oxygen species generation by symbiotic bracovirus. These data established a basis for further studies of parasitoid/host interactions and identified a novel positive self-protection mechanism for the parasitoid.

Abstract
Bacterial and fungal infections still remain an important cause of mortality in patients with hematological malignancies and in recipients of hematopoietic stem cell transplants (HSCT) especially in developing countries like India. Granulocyte transfusions (GTX) from healthy donors may lead to early clearance of index infection and thus prevent mortality. The aim of the present study was to evaluate the efficacy of GTX in combating life-threatening infections and preventing mortality in patients of hematological disorders/recipients of HSCT with severe neutropenia. This study was a prospective, observational analysis of patients with different hematological disorders/recipients of HSCT, who received GTX from January 2014 to December 2017. All patients had an Absolute neutrophil Count (ANC) < 0.5 x 109/L and a life threatening sepsis defined by presence of hemodynamic instability/ impending septic shock/ continuous high fever despite the use of the highest line of antimicrobials. A total of 143 granulocyte collections were done for 66 infectious episodes (IEs) in 60 patients. Multidrug resistant organisms (MDROs) were observed in 47/66 IEs (71.2%) and fungal infections were seen in 9/66 IEs (13.6%). Resolution of index infection after GTX was seen in 45/66 IEs (68.2%), and the 30 day overall survival (OS) was 67.7%. OS was significantly higher in patients who received GTX within 7 days of neutropenic sepsis (p = 0.01). Patients with MDROs who received early GTX therapy had a better OS as compared to those who received late GTX (p = 0.02). GTX were well tolerated and only 6 patients' developed mild features of transfusion related acute lung injury (TRALI) which was managed conservatively, and 1 patient demonstrated hypocalcemic tetany. GTX may be of particular relevance in countries like India, where the incidence of infections is very high in neutropenic patients and there is an increasing emergence of MDROs.

Abstract
In the present work, the effects of the neonicotinoid imidacloprid formulation on the total hemocyte counts (THC) and differential hemocyte counts (DHC) were investigated in foraging workers of the stingless bee Melipona quadrifasciata under (or not) the challenge with the bacteria Escherichia coli. The THC was not altered with the insecticide exposure and/or bacterial infection. However, the DHC of the bees changed with the imidacloprid exposure and/or bacterial infection. The number of prohemocytes (stem cells) increased in bees exposed to imidacloprid, but it did not change after the bacterial infection. The number of plasmatocytes (phagocytic cells) increased in imidacloprid-exposed and uninfected bees and decreased in infected bees regardless of the exposure to imidacloprid. On the other hand, there was a reduction of granulocytes, the most active immune cells, after imidacloprid exposure and an increase of granulocytes after the infection. Previous studies have shown that the neonicotinoids exposure can impair the immune system of bees. Our findings showed that the relative number of granulocytes declined with imidacloprid exposure, but the overall capacity of hemocyte responses in terms of total numbers after bacterial infection persisted even after the insecticide exposure.

Abstract
Despite advances in our understanding of the mechanisms underlying the progression of chronic kidney disease and the development of fibrosis, only limited efficacious therapies exist. The calcium binding protein S100A8/A9 is a damage-associated molecular pattern which can activate Toll-like receptor (TLR)-4 or receptor for advanced glycation end-products (RAGE). Activation of these receptors is involved in the progression of renal fibrosis; however, the role of S100A8/A9 herein remains unknown. Therefore, we analysed S100A8/A9 expression in patients and mice with obstructive nephropathy and subjected wild-type and S100A9 knock-out mice lacking the heterodimer S100A8/A9 to unilateral ureteral obstruction (UUO). We found profound S100A8/A9 expression in granulocytes that infiltrated human and murine kidney, together with enhanced renal expression over time, following UUO. S100A9 KO mice were protected from UUO-induced renal fibrosis, independently of leucocyte infiltration and inflammation. Loss of S100A8/A9 protected tubular epithelial cells from UUO-induced apoptosis and critical epithelial-mesenchymal transition steps. In-vitro studies revealed S100A8/A9 as a novel mediator of epithelial cell injury through loss of cell polarity, cell cycle arrest and subsequent cell death. In conclusion, we demonstrate that S100A8/A9 mediates renal damage and fibrosis, presumably through loss of tubular epithelial cell contacts and irreversible damage. Suppression of S100A8/A9 could be a therapeutic strategy to halt renal fibrosis in patients with chronic kidney disease.

Abstract
Granulocyte function was studied in 9 patients with untreated, Ph1-positive chronic myelocytic leukemia (CML). The nitroblue tetrazolium reduction by stimulated granulocytes was impaired in all patients; 4 patients also had diminished phagocytosis and 2 others defective Chemotaxis. In spite of this variety of polymorphonuclear (PMN) functional impairments, there is little evidence of increased susceptibility to infections in CML patients. This suggests that CML-PMN leucocytes (PMNs) may be successfully used for transfusion into neutropenic recipients, as previously reported. To evaluate the effects of irradiation and liquid storage on CML-PMNs, 5 of our patients were subjected to leukapheresis by continuous-flow centrifugation in the Aminco Celltrifuge, and granulocyte functional capacities were also evaluated on the cell-rich plasma immediately after collection and after short-term storage at 4°C with or without irradiation (1500 rads). As evaluated by in vitro studies, granulocytes maintained, even after irradiation, functional activities similar to those found immediately after collection up to 24 h of storage at 4°C and presented a moderate loss of function after 48 h. Chemotaxis appeared to be the most sensitive detector for cellular damage of stored leucocytes, irradiated and non-irradiated, so that it might be used for assessment of leucocyte function before transfusion.

Abstract
Granulcoyte functions, viz. endocytosis, NADPH oxidase activity and iodination by leukocytes, were studied in granulocytes isolated from 17 chronic myeloid leukemia (CIVIL) patients at initial diagnosis (stage I), from 10 patients in relapse (stage II), and 10 patients in acute blastic crisis (stage III). The mean phagocytic index of granulocytes from CML patients was similar to the normal value. NADPH activity decreased as the disease progressed. Thus, the amount of formazan produced was lower in granulocytes from patients in stage II (P < 0.05) and stage III (P < 0.01) than that produced by normal granulocytes. H2O2-Myeloperoxidase-dependent iodination was found to be significantly reduced in granulocytes from all stages of the disease compared to that of normal, stage I (P < 0.01), stage II (P < 0.05) and stage III (P < 0.01). It thus seems that granulocyte function becomes less efficient as the disease progresses towards acute blastic crisis. Immature cells from the same patients carried out these functions at a more reduced level than did their mature counterparts.

Abstract
Envenomation by Loxosceles spiders can result in severe systemic and local reactions, which are mainly triggered by Sphingomyelinase D (SMase D), a toxic component of Loxosceles venom. SMase D induces a systemic inflammatory condition similar to the reaction observed during an endotoxic shock. Considering the potent pro-inflammatory potential of Loxosceles venom and the SMase D, in this study we have used the whole human blood model to study the endotoxic-like shock triggered by SMase D. Recombinant purified SMase D from L. intermedia venom, similarly to LPS, induced activation of blood leukocytes, as observed by the increase in the expression of CD11b and TLR4, production of reactive oxygen and nitrogen species (superoxide anion and peroxynitrite) and release of TNF-α. Complement consumption in the plasma was also detected, and complement inhibition by compstatin decreased the SMase D and LPS-induced leukocyte activation, as demonstrated by a reduction in the expression of CD11b and TLR4 and superoxide anion production. Similar results were found for the L. intermedia venom, except for the production of TNF-α. These findings indicate that SMase D present in Loxosceles venom is able to activate leukocytes in a partially complement-dependent manner, which can contribute to the systemic inflammation that follows envenomation by this spider. Thus, future therapeutic management of systemic Loxosceles envenomation could include the use of complement inhibitors as adjunct therapy.

Abstract
We have previously reported levels of myeloid cells in the periphery and in the tumor microenvironment (TME) of patients with primary breast cancer (PBC) and colorectal cancer (CRC). We found that both PBC and CRC patients have significantly higher levels of granulocytic and immature myeloid cells in the TME. Additionally, we reported an expansion of circulating granulocytic myeloid cells in CRC patients, but not in PBC patients. In this report, we compared levels of myeloid cells between these two common cancers and have added data from more cancer patients. We also investigated associations between clinical stage/histological grade of tumors and levels of myeloid cells in cancer patients. We found that although granulocytic myeloid cells were expanded in the TME of both PBC and CRC patients, the levels of these cells were significantly higher in the TME of CRC patients. Moreover, our results indicate that increased levels of circulating granulocytic myeloid cells are associated with poorly differentiated tumors in CRC patients. Taken together, this work suggests that CRC patients may benefit more from the development of therapeutic agents to promote myeloid cell differentiation or inhibition for the reversal of immune suppression.

Abstract
Myeloid progenitors reside within specific hematopoietic organs and commit to progenitor lineages bearing megakaryocyte/erythrocyte (MEP) or granulocyte/macrophage potentials (GMP) within these sites. Unlike other vertebrates, the amphibian Xenopus laevis committed macrophage precursors are absent from the hematopoietic subcapsular liver and instead reside within their bone marrow. Presently, we demonstrate that while these frogs' liver-derived cells are unresponsive to recombinant forms of principal X. laevis macrophage (colony-stimulating factor-1; CSF-1) and granulocyte (CSF-3) growth factors, bone marrow cells cultured with CSF-1 and CSF-3 exhibit respectively archetypal macrophage and granulocyte morphology, gene expression and functionalities. Moreover, we demonstrate that liver, but not bone marrow cells possess erythropoietic capacities when stimulated with a X. laevis erythropoietin. Together, our findings indicate that X. laevis retain their MEP within the hematopoietic liver while sequestering their GMP to the bone marrow, thus marking a very novel myelopoietic strategy as compared to those seen in other jawed vertebrate species.

Abstract
Anti-TNF-α therapy with a chimeric monoclonal antibody (Infliximab, Remicade®) has been shown to be highly effective in the treatment of skin lesions as well as arthritis in patients with psoriatic arthritis. In this study we investigated the molecular consequences of the in vivo TNF-α blockade with infliximab in psoriatic skin lesions of 6 patients with severe psoriatic arthritis. Biopsies from lesional and non-lesional skin were taken before and 10 weeks after the initiation of treatment. Immunohistochemistry and semiquantative RT-PCR were performed focusing on proinflammatory gene products. Immunohistochemistry, after three infusions, revealed a marked decrease in the expression of TNF-α, HLA-DR, CD3, CD15, ICAM-1 and LFA-1 positive cells. By semiquantitative RT-PCR, we analysed mRNA expression of IL-8, IL-20, TNF-R (TNF-R p60 and TNF-R p80), IL-1R I and IL-1R II, as well as ICAM-2. Before therapy, m-RNA for IL-8, IL-20, TNF-R p60, TNF-R p80, IL-1R II and ICAM-2 were detected in lesional skin. mRNA expression of IL-8 and IL-20 completely disappeared and mRNA expression of TNF-R p60 was reduced after therapy. This effect on IL-8 expression was paralleled by a decreased infiltration of leukocytes in psoriatic skin. These data suggest that the clinical response of anti-TNF-α therapy in patients with psoriasis or psoriatic arthritis may be, at least in part, caused by the inhibition of the production of proinflammatory cytokines and by the decreased expression of adhesion molecules with the consequence of an impaired migration of proinflammatory cells into the inflamed tissue. These data further support a critical role for TNF-α in the pathology of psoriasis.

Abstract
Peroxinectin possesses the features of both peroxidase activity and adhesive property and plays important roles in innate immune system of crustaceans. In this study, the sequence of peroxinectin of Eriocheir sinensis (EsPX) was analyzed and its expression in response to exterior stimulation was detected in both in vivo and in vitro examination. We showed that the full-length cDNA sequence was composed of 2701 bp and owned a molecular mass of 85.2 kDa and a theoretical pI (isoelectric point) of 6.91. Real-time PCR revealed that the EsPX was mainly distributed in the muscle, hemocytes and stomach. Furthermore, the EsPX was verified to be located in hyalinocytes, semigranulocytes and granulocytes, and was distributed throughout the cytoplasm and nucleus, especial in cytoplasm. After injected with beads, lipopolysaccharide (LPS) and Aeromonas hydrophila, the EsPX mRNA expression was significantly up-regulated and peaked up at 4, 2 and 16 h respectively (P <0.05). In the in vitro experiment, the stimulation of LPS and beads also induced a prominent boost of EsPX protein in primary cultured hemocytes. The expression of EsPX was peaked up at 4 and 8 h for LPS and beads challenged groups respectively, followed by remarkable release of the incremental EsPX into the extracellular matrix. These findings suggested that the expression of EsPX was susceptible to exterior stimulation, and that the highly expressional EsPX would be released into extracellular matrix by the exterior stimulus.

Abstract
Peripheral blood cell counts are important biomarkers of radiation exposure. In this work, a simplified compartmental modeling approach is applied to simulate the perturbation of the hematopoiesis system in humans after radiation exposure, and HemoDose software is reported to estimate individuals' absorbed doses based on multi-type blood cell counts. Testing with patient data in some historical accidents indicates that either single or serial granulocyte, lymphocyte, leukocyte, and platelet counts after exposure can be robust indicators of the absorbed doses. In addition, such correlation exists not only in the early time window (1 or 2 d) but also in the late phase (up to 4 wk) after exposure, when the four types of cell counts are combined for analysis. These demonstrate the capability of HemoDose as a rapid point-of-care diagnostic or centralized high-throughput assay system for personnel exposed to unintended high doses of radiation, especially in large-scale nuclear/radiological disaster scenarios involving mass casualties.

Abstract
Differential hemocyte count of circulating plasmatocytes (PL) and granulocytes (GR) of fifth-instar larvae of Muga Silkworm Antheraea assama Westwood (Lepidoptera: Saturniidae) reared at four different sericulture farms situated at different altitudes, viz, Khanapara State Sericulture Farm, Assam, altitude 55.5 m above sea level (ASL); Nongpoh (Central Silk Board farm), Meghalaya, altitude 464 m ASL; Tura (Central Silk Board farm), West Garo Hills, Meghalaya, 657 m ASL; and Kalimpong (Central Silk Board farm), West Bengal, altitude 1,247 m ASL, were calculated and compared to investigate the effect of altitude on the number of PL and GR per mm(3) of larval hemolymph. The investigation showed that the mean circulating PL and GR were highest at Khanapara (55.5 m ASL) located at the lowest altitude, whereas their numbers gradually decreased with increase in altitude at Nongpoh (464 m ASL), Tura (657 m ASL), and Kalimpong (1,247 m ASL). This may be attributed to the average environmental temperatures observed at different altitudes, which may affect the overall hemocyte load of larval stages reared at those altitudes.

Abstract
OBJECTIVE To study the effectiveness of hemopoietic growth factors in older patients. DESIGN Literature review. All articles published in English language between 1987 and 1990 were reviewed. Those reporting studies without age limits as entry criteria and describing the effects of growth factors in individual patients were suitable for analysis. Bone marrow transplantation related articles were excluded. MAIN OUTCOME MEASURES The meanfold increase of granulocytes for Granulocyte-Colony Stimulating Factor, Granulocyte Macrophage-Colony Stimulating Factor, and Interleukin 3 and of hemoglobin for erythropoietin were compared in subjects younger and older than 65, by Mann-Whitney U test. RESULTS Of 68 studies, 23 were suitable for analysis. These included patients with myelodysplastic syndromes, aplastic anemia, chemotherapy-induced myelosuppression, chronic granulocytopenia, anemia, and myelosuppression of malignancies and of chronic disease. Of 204 patients, 67 were 65 years of age or older and 42 were over 70. No difference was seen in meanfold increase of granulocyte and hemoglobin in time of response to growth factors or in response in presence of an absolute neutrophil count lower than 1000/microliters between younger and older patients. CONCLUSION Early response to hemopoietic growth factors appears well maintained with advanced age. Prospective studies of the prolonged effects of these factors in older and younger patients are needed.

Abstract
The hemocytes of the red claw crayfish Cherax quadricarinatus are classified by morphologic observation into the following types: hyalinocytes (H), semi-granulocytes (SG) and granulocytes (G). Density gradient centrifugation with Percoll was developed to separate these three subpopulations of hemocytes. Beads, Escherichia coli, and FITC labeling WSSV were used to investigate the characteristics of granulocytes by using scanning electron microscope, transmission electron microscope, and laser scan confocal microscope. Results showed that granulocytes could phagocytose beads and E. coli by endocytic pathways. WSSV could rely on caveolae-mediated endocytosis to mainly enter into granulocytes. These results could elucidate the mechanism of the innate immunity function of granulocytes, and it also showed the mechanism by which WSSV invaded granulocytes in the red claw crayfish.

Abstract
BACKGROUND Higher white blood cell count (WBC) is associated with incident type 2 diabetes; however, little is known about the potential relationship of WBC subtypes with metabolic abnormalities underlying diabetes. DESIGN Cross-sectional analysis. PARTICIPANTS Six hundred and fifty-six nondiabetic participants in the Prospective Metabolism and Islet Cell Evaluation cohort. MEASUREMENTS Granulocytes (basophils, neutrophils and eosinophils), lymphocytes and monocytes were measured in fasting blood samples. Neutrophil lymphocyte ratio (NLR) is the ratio of neutrophil to lymphocyte. Insulin resistance was measured by insulin sensitivity index (ISOGTT) and homeostasis model assessment of insulin resistance (HOMA-IR). Beta-cell dysfunction was measured by insulinogenic index (IGI) divided by HOMA-IR (IGI/IR) and Insulin Secretion Sensitivity Index-2 (ISSI-2). RESULTS All WBC subtypes were inversely associated with ISOGTT [β = -0·12 (-0·15, -0·083) for granulocytes, β = -0·23 (-0·31, -0·15) for lymphocytes, β = -0·67 (-1·00, -0·34) for monocytes] and positively associated with HOMA-IR [β = 0·11 (0·074, 0·15) for granulocytes, β = 0·22 (0·14, 0·30) for lymphocytes, β = 0·64 (0·33, 0·97) for monocytes]. Granulocytes and lymphocytes were inversely associated with IGI/IR [β = -0·10 (-0·15, -0·047), β = -0·23 (-0·35, -0·11), respectively] and ISSI-2 [β = -0·048 (-0·074, -0·022), β = -0·14 (-0·19, -0·089), respectively]. BMI attenuated the associations of monocytes with IGI/IR and ISSI-2, and those of NLR with ISOGTT and HOMA-IR. NLR was not associated with IGI/IR and ISSI-2. CONCLUSIONS All WBC subtypes were independently associated with insulin resistance, whereas granulocytes and lymphocytes, but not monocytes, were associated with β-cell dysfunction. NLR was not associated with β-cell dysfunction, and its association with insulin resistance was confounded by obesity.

Abstract
Leukocyte adhesion deficiency type 1 (LAD-1) is an autosomal recessive disorder, caused by the absence or reduced expression of the beta-2 integrins on granulocytes, and characterized by the inability of these cells to emigrate from the bloodstream towards the sites of tissue inflammation. A twelve-year-old girl with a diagnosis of LAD-1 syndrome and recurrent skin and mucosal infections since birth, presented with a two week history of fever, abdominal pain, vomiting, weight loss and polyarthralgia. She underwent an exploratory laparotomy with the finding of inflamed terminal ileum and colon and a normal appendix. Colonoscopy and videocapsule endoscopy showed multiple ileal and colonic mucosal ulcerations, which were compatible with inflammatory bowel disease, confirmed on histological examination. Given the lack of response to conventional therapy (prednisone and mesalamine), a monoclonal anti-TNF-α antibody was started at a dosage of 5 mg/kg at weeks 0,2,4,6 and then every 8 weeks. We observed a significant improvement of all clinical and laboratory parameters after the first weeks of therapy. Five months later, we anticipated the drug's administration every 5 weeks because of a precocious recurrence of symptoms. After 30 months of treatment no relapse nor any relevant side effects have been observed, and corticosteroids were withdrawn. Interestingly, our patient presented a small subset of CD18+ T cells, similarly to previously reported LAD-1 patients with mild phenotype, inflammatory bowel disease and CD18+ somatic revertant T cells. To the best of our knowledge, this is the first LAD-1 pediatric patient with inflammatory autoimmune complications who experienced a positive response to anti-TNF-α treatment.

Abstract
Functional overreaching has been linked to alterations in immunity and host pathogen defense, but little is known as to whether or not running and cycling evoke different responses. This study compared inflammation, muscle damage and soreness, and innate immune function responses to a 3-day period of intensified exercise in trained long distance runners (N=13, age 34.4±2.4year) and cyclists (N=22, age 36.6±1.7year, P=0.452). Upper respiratory tract infection (URTI) symptomatology was monitored for 12weeks using the Wisconsin Upper Respiratory Symptom Survey (WURSS), and subjects from both athletic groups came to the lab during week five and exercised 2.5h/day for 3days in a row at 70% VO2max. Blood samples were collected before and after the 3-day period of exercise, with recovery samples collected 1-, 14-, and 38h-post-exercise. Samples were analyzed for muscle damage [creatine kinase (CK), myoglobin (MYO)], inflammation (CRP, IL-6, IL-8, IL-10, MCP), and innate immunity [granulocyte and monocyte phagocytosis (GR-PHAG and MO-PHAG) and oxidative burst activity (GR-OBA and MO-OBA)]. Runners compared to cyclists experienced significantly more muscle damage (CK 133% and MYO 404% higher post-3days exercise), inflammation (CRP 87%, IL-6 256%, IL 8 61%, IL-10 32%, MCP 29%), and delayed onset of muscle soreness (DOMS, 87%). The 3-day period of exercise caused significant downturns in GR-PHAG, MO-PHAG, GR-OBA, MO-OBA by 14- and 38h-recovery, but the pattern of change did not differ between groups. No group differences were measured for 12-week URTI severity (18.3±5.6 and 16.6±4.0, P=0.803) and symptom scores (33.4±12.6 and 24.7±5.8, P=0.477). These data indicate that a 3-day period of functional overreaching results in substantially more muscle damage and soreness, and systemic inflammation in runners compared to cyclists, but without group differences for 12-week URTI symptomatology and post-exercise decrements in innate immune function.

Abstract
Two Brazilian species of Dimerostemma (Asteraceae) were chemically investigated. Two known sesquiterpene lactones (STLs), a germacrolide and an eudesmanolide, were isolated from D. episcopale while D. brasilianum afforded the new germacranolide 1β,5β,10α-trihydroxy- 8α-angeloyloxy-germacra-3,11(13)-dien-6α,12-olide in addition to a known one. Structure identification based on NMR and MS analyses. 1β,10α,4α,5β-Diepoxy-8α-angeloyloxycostunolide isolated from D. brasilianum was studied for its anti-inflammatory activity. This STL completely inhibited DNA binding of the transcription factor NF-κB at a concentration of 5 μм and 10 μм in Jurkat T and Raw 264.7 cells, respectively. Elastase release from human neutrophils was reduced to 50% at a concentrations of 23 μм after stimulation with PAF and of 27 μм after stimulation with fMLP without showing cytotoxic effects. Additionally, elastase was also directly inhibited.

Abstract
BACKGROUND Acute appendicitis is the most common cause of abdominal surgery in children. Adjuncts are used to help clinicians predict acute or perforated appendicitis, which may affect treatment decisions. Automated hematologic analyzers can perform more accurate automated differentials including immature granulocyte percentages (IG%). Elevated IG% has demonstrated improved accuracy for predicting sepsis in the neonatal population than traditional immature-to-total neutrophil count ratios. We intended to assess the additional discriminatory ability of IG% to traditionally assessed parameters in the differentiation between acute and perforated appendicitis. MATERIALS AND METHODS We identified all patients with appendicitis from July 2012-June 2013 by International Classification of Diseases-9 code. Charts were reviewed for relevant demographic, clinical, and outcome data, which were compared between acute and perforated appendicitis groups using Fisher exact and t-tests for categorical and continuous variables, respectively. We used an adjusted logistic regression model using clinical laboratory values to predict the odds of perforated appendicitis. RESULTS A total of 251 patients were included in the analysis. Those with perforated appendicitis had a higher white blood cell count (P=0.0063), C-reactive protein (CRP) (P<0.0001), and IG% (P=0.0299). In the adjusted model, only elevated CRP (odds ratio 3.46, 95% confidence interval 1.40-8.54) and presence of left shift (odds ratio 2.66, 95% confidence interval 1.09-6.46) were significant predictors of perforated appendicitis. The c-statistic of the final model was 0.70, suggesting fair discriminatory ability in predicting perforated appendicitis. CONCLUSIONS IG% did not provide any additional benefit to elevated CRP and presence of left shift in the differentiation between acute and perforated appendicitis.

Abstract
Our current understanding of the lungfish immune system is limited. This study is characterizing the immune cells separated from primary and secondary immune organs of the Australian lungfish, Neoceratodus forsteri. Our functional studies utilized flow cytometry to study the immune cells extracted from the thymus, spiral valve intestine, spleen, and kidney. The different characteristics of lymphocytes and granulocytes were analyzed by utilization of viability, phagocytosis, oxidative burst, and apoptosis assays. Most of the nonviable intestinal cells were lymphocytes. Depending on the organ, 6-25% of the total population, predominantly granulocytes, underwent phagocytosis where the splenic cells were the most and intestinal cells the least phagocytic cells. Cells responded positively but differently to stimulation with phorbol myristate acetate (PMA) to produce radical oxygen species, an indication of their oxidative burst activity, which was mainly associated with granulocytes. Although cells were induced by dexamethasone to undergo apoptosis, such an induction did not follow a consistent pattern of dose of dexamethasone or incubation time between the different organs. In the absence of monoclonal antibodies against lungfish immune cells, these functional flow cytometric analyses aid our understanding on the functionality of immune cells.

Abstract
The inflammatory response following traumatic brain injury (TBI) contributes to neuronal death with poor outcome. Although anti-inflammatory strategies were beneficial in the experimental TBI, clinical translations mostly failed, probably caused by the complexity of involved cells and mediators. We recently showed in a rat model of controlled cortical impact (CCI) that leukotriene inhibitors (LIs) attenuate contusion growth and improve neuronal survival. This study focuses on spatiotemporal characteristics of macrophages and granulocytes, typically involved in inflammatory processes, and neuronal COX-2 expression. Effects of treatment with LIs (Boscari/MK-886), started prior trauma, were evaluated by quantifying CD68(+), CD43(+) and COX-2(+) cells 24h and 72 h post-CCI in the parietal cortex (PC), CA3 region, dentate gyrus (DG) and visual/auditory cortex (v/aC). Correlations were applied to identify intercellular relationships. At 24h, untreated animals showed granulocyte invasion in all regions, decreasing towards 72 h. Macrophages increased from 24h to 72 h post-CCI in PC and v/aC. COX-2(+) neurones showed no temporal changes, except of an increase in the CA3 region at 72 h. Treatment reduced granulocytes at 24h in the pericontusional zone and hippocampus, and macrophages at 72 h in the PC and v/aC. COX-2 expression remained unaffected by LIs, except of time-specific changes in the DG (increase/decrease at 24/72 h). Interrelations confirmed concomitant cellular reactions beyond the initial trauma site. In conclusion, LIs attenuated the cellular inflammatory response following CCI. Future studies have to clarify region-specific effects and explore the potential of a clinically more relevant therapeutic approach applying LIs after CCI.

Abstract
The present study was undertaken to develop a respirable sustained-release powder (RP) formulation of long-acting VIP derivative, [Arg(15, 20, 21), Leu(17)]-VIP-GRR (IK312532), using PLGA nanospheres (NS) with the aim of improving the duration of action. NS formulation of IK312532 (IK312532/NS) was prepared by an emulsion solvent diffusion method in oil, and a mixture of the IK312532/NS and erythritol was jet-milled and mixed with lactose carrier to obtain the IK312532/NS-RP. Physicochemical properties were characterized focusing on appearance, particle size, and drug release, and in vivo pharmacological effects were assessed in antigen-sensitized rats. The IK312532/NS with a diameter of 140 nm showed a biphasic release pattern in distilled water with ca. 20% initial burst for 30 min and a sustained slow release up to ca. 55% for 24h. Laser diffraction analysis demonstrated that IK312532/NS-RP had fine dispersibility and suitable particle size for inhalation. In antigen-sensitized rats, insufflated IK312532/NS-RP (10 μg of IK312532/rat) could suppress increases of granulocyte recruitment and myeloperoxidase in pulmonary tissue for up to 24h after antigen challenge, although IK312532-RP at the same dose was less effective with limited duration of action. From these findings, newly prepared IK312532/NS-RP might be of clinical importance in improving duration of action and medication compliance for treatment of airway inflammatory diseases.

Abstract
Morphometrical parameters, osmoregulatory possibilities, and the membrane reserve value of nuclear hemocytes (leukocytes and erythrocytes) were studied in the main classes of vertebrates by using method of hypoosmotic loads. It has been established that in the fish--mammals line in erythrocytes the absolute reserve of the plasmalemma decreases and the relative area of the cell surface increases. Evolution of leukocytes is accompanied by an increase of the membrane reserve and of the surface area due to a decrease of volume and to a rise of folding of the plasmalemma.

Abstract
OBJECTIVE To perform phenotypic identification and characteristic analysis of a new zebrafish mutant 1276 defective in primitive myelopoiesis. METHODS The AB strain male zebrafish were mutagenized with N-ethyl N-nitrosourea (ENU) to induce mutations in the spermatogonial cells, and the mutations were transmitted to the offsprings. The F3 embryos were screened by neutral red staining for identifying the mutants defective in primitive myelopoiesis. One of the myeloid mutants 1276 was further studied by cytochemistry and whole mount in stiu hybridization (WISH) with different lineage markers. RESULTS A total of 2140 mutagenized genomes from the 1296 F2 families were analyzed, and 12 mutants were identified to show abnormal signal by neutral red staining. In the primitive hematopoiesis stage, the mutant 1276 showed the absence of neutral red staining-positive cells in the whole body. The expression of microglia marker apoe was totally lost in the head of the mutant, and the expression of the macrophage marker l-plastin was slightly decreased in the head and remained normal in the ventral dorsal aorta region, but the granulocytes and erythrocytes developed normally. in the definitive hematopoiesis stage, the mutant 1276 still showed abnormal macrophages as found in the primitive hematopoiesis stage, but the granulocytes, erythrocytes and lymphocytes appeared normal. CONCLUSION The zebrafish mutant 1276 shows abnormalities in the function, development and migration of the macrophages in the primitive hematopoiesis stage, which can not be compensated in the definitive hematopoiesis stage.

Abstract
Polymorphonuclear neutrophils (PMN) mediate early immunity to infection but can also cause host damage if their effector functions are not controlled. Their lack or dysfunction is associated with severe health problems and thus the analysis of PMN physiology is a central issue. One prerequisite for PMN analysis is the availability of purified cells from primary organs. While human PMN are easily isolated from peripheral blood, this approach is less suitable for mice due to limited availability of blood. Instead, bone marrow (BM) is an easily available reservoir of murine PMN, but methods to obtain pure cells from BM are limited. We have developed a novel protocol allowing the isolation of highly pure untouched PMN from murine BM by negative immunomagnetic isolation using a complex antibody cocktail. The protocol is simple and fast (∼1 h), has a high yield (5–10*106 PMN per animal) and provides a purity of cells equivalent to positive selection (>80%). Most importantly, cells obtained by this method are non-activated and remain fully functional in vitro or after adoptive transfer into recipient animals. This method should thus greatly facilitate the study of primary murine PMN in vitro and in vivo.

Abstract
As significant ionising radiation exposure will occur during prolonged space travel in future, it is essential to understand their adverse effects on the radiosensitive organ systems that are important for immediate survival of humans, e.g. the haematopoietic system. In this paper, a biomathematical model of granulopoiesis is used to analyse the granulocyte changes seen in the blood of mammalians under acute and continuous radiation exposure. This is one of a set of haematopoietic models that have been successfully utilised to simulate and interpret the experimental data of acute and chronic radiation on rodents. Extension to canine and human systems indicates that the results of the model are consistent with the cumulative experimental and empirical data from various sources, implying the potential to integrate them into one united model system to monitor the haematopoietic response of various species under irradiation. The suppression of granulocytes' level of a space traveller under chronic stress of low-dose irradiation as well as the granulopoietic response when encountering a historically large solar particle event is also discussed.

Abstract
We recently showed that in vitro heterophil functional efficiency in commercial broiler chickens is genetically controlled and may be a sex-associated trait. To further characterize the genetic mechanism(s) of heterophil functional efficiency, we wanted to determine whether the feathering gene, present on the Z sex chromosome, contributes to heterophil functional efficiency. Heterophils from two pairs of broiler lines were evaluated; each pair contained a fast feather (FF) (lines A and X) and a slow feather (SF) line (lines B and Y). On days 1 and 4 post-hatch, heterophils isolated from two sets of pure line broilers (A and B, and X and Y) were evaluated for their ability to (1) phagocytize Salmonella enteritidis, and (2) exhibit bactericidal activity against S. enteritidis. On days 1 and 4 post-hatch, heterophils isolated from the FF lines were statistically (P < or = 0.02) more proficient at phagocytizing S. enteritidis than heterophils from SF lines. Bactericidal activity was also statistically (p < or = 0.02) greater on day 1 post-hatch in the heterophils isolated from FF lines compared to heterophils isolated from SF lines. These data indicate that the presence of the FF gene locus on the Z sex chromosome contributes to heterophil function and may contribute to the early innate immune competence of a flock.

Abstract
BACKGROUND Surgery renders patients susceptible to life-threatening complications, including infections, multiple organ failure, and presumably cancer metastases. Surgery-induced immune perturbations were suggested to contribute to such deleterious effects, but also to facilitate post-injury healing. Preoperative psychological and physiological stress responses may contribute to these immune perturbations, and could thus jeopardize patients even before surgery. The current study assessed the effects of various operations on an array of immune indices during the perioperative period. To qualify immune changes before surgery, patients' immune status was also compared to that of healthy controls. METHODS A total of 81 subjects (operated patients and healthy controls) provided up to five daily blood samples during the perioperative period, for assessment of leukocyte subtypes (granulocytes, monocytes, Tc, Th, NK, NKT, CD4+CD25+, CD8(bright)CD4(dim), and B cells) and their surface markers (HLA-DR and LFA-1). RESULTS Even before surgery patients displayed immune perturbations, including reduced lymphocyte HLA-DR expression and increased monocyte LFA-1 expression. Following surgery, we recorded a reduction in lymphocyte numbers that was subtype specific, increased granulocyte numbers, and reduced expression of HLA-DR by lymphocytes and monocytes. Finally, no significant associations were found between alteration in leukocyte numbers and cell surface markers (although these indices showed high correlations with other variables), implying differential mediating mechanisms. CONCLUSION Several immune alterations are manifested prior to surgery, and contribute to the marked postoperative changes, which are commonly interpreted as immune suppression. We discuss the possible adaptive and maladaptive nature of these perturbations in the context of natural injury, stress, and surgery.

Abstract
Recent studies indicated that antimicrobial peptides (AMPs) play multiple roles in both innate and adaptive immune functions. The penaeidin of tiger shrimp Penaeus monodon shows an antimicrobial activity against Gram-positive bacteria and filamentous fungi. To study immunomodulation functions of the penaeidin, we transfected shrimp hemocytes in primary culture with penaeidin-specific small interfering RNA (siRNA-3) and observed a concomitant 20% reduction in adhesive hemocytes compared with mock-transfected cells. The addition of biosynthesized or chemically synthesized penaeidin or penaeidin proline-rich domain (PRD) to the culture medium of penaeidin knock-down hemocytes led to a full recovery in the number of adhesive hemocytes. The effect of penaeidin knock-down on the expression of tiger shrimp cell adhesion-associated molecules was examined using real-time Q-PCR. Results demonstrated 91% and 64% decreases in the expression of integrin-beta and collagen, respectively, and a 396% increase in the expression of collagenase. The addition of chemically synthesized penaeidin after penaeidin knock-down hemocytes normalized the expression of these genes. The addition of the integrin-beta ligand competitor RGDS to mock-transfected hemocytes decreased the number of adhesive hemocytes similar to penaeidin knock-down. In conclusion, penaeidin possesses an integrin-beta-mediated cytokine feature that promotes shrimp granulocyte and semi-granulocyte adhesion. This is the first report about functional shrimp cytokine.

Abstract
BACKGROUND The chemotactic signals regulating cell trafficking in the herpes simplex virus type 1 (HSV-1) infected cornea are well documented, however, those in the cornea-associated tissues, such as the trigeminal ganglion (TG) and draining lymph nodes (LNs), are largely unknown. OBJECTIVES To examine chemokine expression and subsequent cell infiltration in the HSV-1 infected cornea and its associated tissues. STUDY DESIGN Eight-week-old female BALB/c mice were infected with 10 mu l HSV-1 (CHR3 strain: 5 x 106 PFU/ml) by corneal scarification. Total RNAs were extracted from the corneas, TGs, and LNs at pre-inoculation, 3 days post-inoculation (P.I.) and 7 days P.I. The mRNA for 28 different chemokines in the extracts was amplified by RT-PCR. Infiltrating cells were identified by immunohistochemistry. RESULT After the HSV-1 infection, the corneal stroma became edematous by infiltrated cells under the eroded epithelium. The TG and LNs were markedly swollen. The cornea was infiltrated with granulocytes and CD11b+ cells at 3 days P.I., followed by CD4+ and CD8+ T cells at 12 days P.I. In the TG, CD11b+ cells, but no granulocytes, infiltrated throughout the observation period. T cells migrated into the TG earlier than into the cornea. Gene expressions of neutrophil-attracting chemokines (CXCL1, 2, 3, and 5) increased in the cornea, but they did not enhance in the TG or LNs. On the other hand, gene expressions of chemokines which attract CD11b+ cells such as CCL2, 8, 7, 12, CCL3, 4, and CCL5, increased in the cornea and TG with its peak at 3 days P.I. Gene expressions of chemokines those work on T cells and B cells, such as CCL19, CCL21, CXCL9, CXCL13, CXCL10, XCL1, and CXCL16, were up-regulated and peaked at 3 days P.I. in the cornea and in the TG. Thus, pattern of chemokine gene expression was similar in the cornea and in the TG. On the contrary, gene expressions of chemokines in the draining LNs affecting CD11b+ cells and T cells were temporarily down-regulated. CONCLUSION Upon HSV-1 infection, dynamic gene expression of chemokines was observed not only in the inoculated cornea but also in its associated tissues.

Abstract
Regulatory T cells (T(reg)) have an essential role in maintaining immune tolerance in the gut. The functional CD4(+) T(reg) express the transcription factor forkhead box protein 3 (FoxP3) or a CD25(high) in humans. Further, depletion of elevated granulocytes/monocytes by extracorporeal adsorption (GMA) induces immunomodulation in patients with ulcerative colitis (UC). We investigated the impact of GMA on T(reg). Thirty-one UC patients, clinical activity index (CAI) 12.1 +/- 2.97, refractory to conventional medications including intravenous corticosteroid and 13 healthy controls (HC), were included. Patients received five GMA sessions over 5 weeks. Biopsies from the rectal mucosa and blood samples at baseline and post-GMA were immunostained with anti-CD4/FoxP3 and anti-CD4/CD25 antibodies for immunohistochemistry and flow cytometry. Following GMA, 22 of 31 patients achieved remission (CAI <or= 4, P < 0.01) and their endoscopic activity index decreased from 10.6 +/- 2.32 to 4.75 +/- 1.48 (P = 0.003). The circulating CD4(+)CD25(high+) T(reg) level was low and increased markedly in responders (P < 0.02). In the nine non-responders, the baseline CD4(+)CD25(high+) T(reg) level was about 50% of the level in the responders (P < 0.03) or in the HC (P < 0.01), and all nine had to undergo colectomy. Conversely, the number of CD4(+)/FoxP3(+) mucosal T(reg) in GMA responders decreased significantly after the fifth GMA session compared with the baseline level (P < 0.05). It is believed that the CD4(+) T(reg) has an essential role in the control of immune pathology in UC patients and a net influx of these cells from the circulation into the mucosa may proceed to suppress inflammation. GMA can impact the circulating as well as the mucosal levels of T(reg).

Abstract
AML1-ETO and TEL-AML1 are chimeric proteins resulting from the t(8;21)(q22;q22) in acute myeloid leukemia, and the t(12;21)(p13;q22) in pre-B-cell leukemia, respectively. The Runt domain of AML1 in both proteins mediates DNA binding and heterodimerization with the core binding factor beta (CBFbeta) subunit. To determine whether CBFbeta is required for AML1-ETO and TEL-AML1 activity, we introduced amino acid substitutions into the Runt domain that disrupt heterodimerization with CBFbeta but not DNA binding. We show that CBFbeta contributes to AML1-ETO's inhibition of granulocyte differentiation, is essential for its ability to enhance the clonogenic potential of primary mouse bone marrow cells, and is indispensable for its cooperativity with the activated receptor tyrosine kinase TEL-PDGFbetaR in generating acute myeloid leukemia in mice. Similarly, CBFbeta is essential for TEL-AML1's ability to promote self-renewal of B cell precursors in vitro. These studies validate the Runt domain/CBFbeta interaction as a therapeutic target in core binding factor leukemias.
