Abstract
The avian immune system responds to Salmonella infection by expressing cytokines and chemokines. We hypothesized that the immune status of Salmonella Typhimurium (ST) challenged neonatal broilers would differ from the uninfected treatment. The objective of this experiment was to evaluate 12 cytokines. Day of hatch male chicks were randomly allocated into a control or ST challenged group. At day three of age, sterile diluent or 5.0 × 108 CFU of ST was given orally to each chick. Blood was obtained 24 h post challenge and serum separated for later analysis (n = 30 chicks/treatment). Significant (p ≤ 0.05) increases in pro-inflammatory cytokines-interleukin-6 (IL-6), IL-16, and IL-21; anti-inflammatory cytokines- IL-10; chemokines-regulated on activation, normal T cell expressed and secreted (RANTES), macrophage inflammatory protein-1β (MIP-1β), and MIP-3α; colony stimulating factors-macrophage colony-stimulating factor (M-CSF); and growth factors-vascular endothelial growth factor (VEGF) were observed in the serum of the challenged chicks when compared to the control. No significant differences were observed in IL-2, interferon gamma (IFNγ), and IFNα. These data indicate the detection of mucosal immune responses in broiler chickens following ST infection. The heightened levels of pro-inflammatory cytokines, chemokines, and colony stimulating factors align with known inflammatory mechanisms, like the influx of immune cells. However, the elevation of IL-10 was unexpected, due to its immunoregulatory properties. Notably, the rise in VEGF levels is compelling, as it suggests the possibility of tissue repair and angiogenesis in ST infected birds.

Abstract
Cytokines and metabolic pathway-controlling enzymes regulate immune responses and have potential as powerful tools to mediate immune tolerance. Blockade of the interaction between CD40 and CD40L induces long-term cardiac allograft survival in rats through a CD8+CD45RClo Treg potentiation. Here, we have shown that the cytokine IL-34, the immunoregulatory properties of which have not been previously studied in transplantation or T cell biology, is expressed by rodent CD8+CD45RClo Tregs and human FOXP3+CD45RCloCD8+ and CD4+ Tregs. IL-34 was involved in the suppressive function of both CD8+ and CD4+ Tregs and markedly inhibited alloreactive immune responses. Additionally, in a rat cardiac allograft model, IL-34 potently induced transplant tolerance that was associated with a total inhibition of alloantibody production. Treatment of rats with IL-34 promoted allograft tolerance that was mediated by induction of CD8+ and CD4+ Tregs. Moreover, these Tregs were capable of serial tolerance induction through modulation of macrophages that migrate early to the graft. Finally, we demonstrated that human macrophages cultured in the presence of IL-34 greatly expanded CD8+ and CD4+ FOXP3+ Tregs, with a superior suppressive potential of antidonor immune responses compared with non-IL-34-expanded Tregs. In conclusion, we reveal that IL-34 serves as a suppressive Treg-specific cytokine and as a tolerogenic cytokine that efficiently inhibits alloreactive immune responses and mediates transplant tolerance.

Abstract
Macrophage-colony stimulating factor (CSF-1) signaling through its receptor (CSF-1R) promotes the differentiation of myeloid progenitors into heterogeneous populations of monocytes, macrophages, dendritic cells, and bone-resorbing osteoclasts. In the periphery, CSF-1 regulates the migration, proliferation, function, and survival of macrophages, which function at multiple levels within the innate and adaptive immune systems. Macrophage populations elicited by CSF-1 are associated with, and exacerbate, a broad spectrum of pathologies, including cancer, inflammation, and bone disease. Conversely, macrophages can also contribute to immunosuppression, disease resolution, and tissue repair. Recombinant CSF-1, antibodies against the ligand and the receptor, and specific inhibitors of CSF-1R kinase activity have been each been tested in a range of animal models and in some cases, in patients. This review examines the potential clinical uses of modulators of the CSF-1/CSF-1R system. We conclude that CSF-1 promotes a resident-type macrophage phenotype. As a treatment, CSF-1 has therapeutic potential in tissue repair. Conversely, inhibition of CSF-1R is unlikely to be effective in inflammatory disease but may have utility in cancer.

Abstract
Ingested type I IFN and SIRS peptide inhibit EAE. We examined whether another immunoactive protein, ACTH, would have similar anti-inflammatory effects in EAE after oral administration. B6 mice were immunized and gavaged with control saline or ACTH starting on the onset of disease. ACTH decreased clinical score and decreased inflammatory foci. CNS lymphocytes showed decreases in IL-17 (T(eff)) and Th1-like encephalitogenic cytokines IL-2 and IFN-γ in the ACTH fed group compared to the mock fed group. Adoptive transfer of ACTH fed splenocytes into MOG immunized recipient mice with early clinical disease suppressed disease severity compared to splenocytes from mock fed donors. The protected recipients showed decreased splenic IL-17 (T(eff)) and Th1-like cytokine IFN-γ and increased CNS secretion of immunoregulatory IL-4 and chemokine M-CSF. Splenic CD4+CD25+ FoxP3+ frequency doubled in ACTH fed compared to control fed mice. Increased immuno-regulatory IL-4 and M-CSF secreting cell populations is the mechanism of protection in adoptively protected recipients and reflects the direct action of ACTH on the immune system.

Abstract
Dendritic cells have been considered an immune cell type that is specialized for the presentation of Ag to naive T cells. Considerable effort has been applied to separate their lineage, pathways of differentiation, and effectiveness in Ag presentation from those of macrophages. This review summarizes evidence that dendritic cells are a part of the mononuclear phagocyte system and are derived from a common precursor, responsive to the same growth factors (including CSF-1), express the same surface markers (including CD11c), and have no unique adaptation for Ag presentation that is not shared by other macrophages.

Abstract
We conducted a comparative study of NK1.1+ cells in spleen and bone marrow and the effects of administration of M-CSF on them. Administration of M-CSF to mice increased the number of NK1.1+ cells in spleen but not in bone marrow. The NK1.1+ cells in spleen (Spl-NK1.1) and bone marrow (BM-NK1.1) were purified by magnetic cell sorter. Their cell surface markers and functions were then examined. The percentage of Mac-1 antigen-positive cells (and F4/80 antigen-positive cells) was higher among BM-NK1.1 than Spl-NK1.1. Moreover, the administration of M-CSF increased the number of Mac-1 and F4/80 antigen-positive cells in both Spl-Nk1.1 and BM-NK1.1. The functions (cytolytic activity and IFN-gamma production) of Spl-NK1.1 and BM-NK1.1 were the same and were enhanced by the administration of M-CSF. But Spl-NK1.1 produced more IFN-gamma than BM-NK1.1 when M-CSF was administered. BM-NK1.1 showed a greater proliferative response to IL-2 than Spl-NK1.1. Administration of M-CSF augmented this response. BM-NK1.1 proliferated in response to IL-4 and IL-15, but Spl-NK1.1 responded only slightly. However, administration of M-CSF stimulated Spl-NK1.1 to respond to these cytokines. Both Spl-NK1.1 and BM-NK1.1 showed only a weak response to M-CSF in vitro. But the expression of c-fms antigen (M-CSFR) increased after the M-CSF injections in vivo. These results suggested that there are phenotypical and functional differences between Spl-NK1.1 and BM-NK1.1. The administration of M-CSF led to an accumulation of NK1.1+ cells which were mobilized from bone marrow in spleen.

Abstract
Marek's disease virus (MDV) is a herpesvirus that induces T lymphomas in chickens. The aim of this study was to assess the role of the macrophage activator chicken myelomonocytic growth factor (cMGF) in controlling MDV infection. B13/B13 chickens, which are highly susceptible to MD, were either treated with cMGF delivered via a live fowlpox virus (fp/cMGF) or treated with the parent vector (fp/M3) or were left as untreated controls. Seven days later, when challenged with the very virulent RB-1B strain of MDV, the spleens of chickens treated with fp/cMGF showed increased expression of the inducible nitric oxide synthase (iNOS) gene compared to those of control chickens and fp/M3-treated chickens. Increased iNOS gene expression was also accompanied by greater induction of gamma interferon and macrophage inflammatory protein (K203) gene expression, both possible activators of iNOS. fp/cMGF treatment also increased the number of monocytes and systemic NO production in contrast to fp/M3 treatment. Even though cMGF treatment was unable to prevent death for the chickens, it did prolong their survival time, and viremia and tumor incidence were greatly reduced. In addition, cMGF treatment improved the partial protection induced by vaccination with HVT (herpesvirus isolated from turkeys) against RB-1B, preventing 100% mortality (versus 66% with vaccination alone) and greatly reducing tumor development. Treatment with fp/M3 did not have such effects. These results suggest that cMGF may play multiple roles in protection against MD. First, it may enhance the innate immune response by increasing the number and activity of monocytes and macrophages, resulting in increased NO production. Second, it may enhance the acquired immune response, indicated by its ability to enhance vaccine efficacy.

Abstract
Adoptive transfer of activated macrophages, being both effector cells and antigen-presenting cells, represents a promising approach to immunotherapy of cancer. In order to get activated macrophages with increased antitumor potential, in the present study, murine peritoneal macrophages were transduced with human macrophage colony-stimulating factor (M-CSF) and murine interferon-gamma (IFNgamma) by recombinant adenovirus infection. The results demonstrate that M-CSF and IFNgamma gene-modified macrophages exhibited higher expression of MHC-II, B7.1 and ICAM-1, increased antigen-presenting activity and cytotoxicity. It was also shown that they secreted more tumor necrosis factor, interleukin-1 and nitric oxide. In vivo experiments showed that in previously initiated murine pulmonary metastatic melanoma, tumor lysate-pulsed, M-CSF and IFNgamma gene-modified macrophages elicited more potent antitumor effects than tumor lysate pulsed M-CSF or IFNgamma gene-modified macrophages. Cytotoxic T lymphocyte (CTL) activity, IFNgamma and tumor-necrosis factor production of the splenocytes increased significantly in mice after intravenous injection of the gene-modified macrophages. M-CSF and IFNgamma gene-modified macrophages may act as activated effector and antigen-presenting cells, thus eliciting a more potent antitumor response.

Abstract
Trichosporon asahii is an emerging opportunistic pathogen in immunocompromised patients. Little is known about the mechanisms of host defence against T. asahii. We investigated the fungicidal activity of human peripheral blood monocytes and murine peritoneal macrophages against T. asahii isolates, and the effects of M-CSF on the anti-fungal activity of mononuclear phagocytes. We also established a neutropenic mouse model of disseminated trichosporonosis with T. asahii. M-CSF enhanced the phagocytic fungicidal activity of mononuclear cells, and infected mice treated with human M-CSF at 10 x 106 U/kg showed a significant improvement in survival rate, with fewer fungal colony counts in the lung compared with control mice. Mice treated with human M-CSF showed higher concentrations of tumour necrosis factor-alpha (TNF-alpha) in the lung and plasma compared with control mice. The survival rate was significantly reduced in mice treated with anti-mouse TNF-alpha. Our results showed that M-CSF enhanced the fungicidal activity of mononuclear phagocytes partly by production of TNF-alpha, and suggest that the administration of M-CSF to patients with disseminated trichosporonosis may be a useful adjunct to conventional anti-microbial therapy and prophylaxis.
