Abstract
Aberrant activation of CD4 TH2 cells and excessive production of TH2 cytokines such as IL-4 and IL-13 have been implicated in the pathogenesis of allergic diseases. Generally, IL-4 and IL-13 utilize Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathways for induction of inflammatory gene expression and the effector functions associated with disease pathology in many allergic diseases. However, it is increasingly clear that JAK/STAT pathways activated by IL-4/IL-13 can themselves be modulated in the presence of other intracellular signaling programs, thereby changing the overall tone and/or magnitude of IL-4/IL-13 signaling. Apart from direct activation of the canonic JAK/STAT pathways, IL-4 and IL-13 also induce proinflammatory gene expression and effector functions through activation of additional signaling cascades. These alternative signaling cascades contribute to several specific aspects of IL-4/IL-13-associated cellular and molecular responses. A more complete understanding of IL-4/IL-13 signaling pathways, including the precise conditions under which noncanonic signaling pathways are activated, and the impact of these pathways on cellular- and host-level responses, will better allow us to design agents that target specific pathologic outcomes or tailor therapies for the treatment of uncommon disease endotypes.

Abstract
Monocyte-derived dendritic cells (mo-DCs) are essential for the development of a Th1 protective immune response against Leishmania parasites. It is well known that IL-4 and GM-CSF drive differentiation of human monocytes to dendritic cells (DCs). Here, we investigate if neutrophil extracellular traps (NETs) disrupt this process. NETs-enriched supernatants, generated after human neutrophil activation by Leishmania promastigotes, were added to monocytes and differentiation monitored by expression of molecules associated with macrophage and DCs phenotypes, cytokine production, and parasite killing. We found that NETs addition to IL-4/GM-CSF-treated monocytes prevented then to fully differentiate into DCs. No effect was observed if NETs were treated with DNase or by filtering the traps. Moreover, NETs closely interact with monocytes and downregulate the expression of the IL-4 receptor, which in turn disrupts fully differentiation of monocytes into DCs. Neutrophil elastase inhibition rescues the monocytes to DCs differentiation. Monocytes cultured with IL-4/GM-CSF and NETs differentiated into macrophages, as observed by the increased expression of CD68, CD32, and CD163, and decreased expression of CD80. Moreover, NET addition to IL-4/GM-CSF-treated monocytes rendered these cells less efficient to kill Leishmania parasites. Altogether, our results show that NETs interfere with IL-4/GM-CSF driven differentiation, reprogramming the generation of mo-DCs to an anti-inflammatory macrophage.

Abstract
BACKGROUND Atopic dermatitis (AD) is a common disease with an increasing prevalence. The primary pathogenesis of the disease is still elusive, resulting in the lack of specific treatments. AD is currently considered a biphasic disease, with T(H)2 predominating in acute disease and a switch to T(H)1 characterizing chronic disease. Elucidation of the molecular factors that participate in the onset of new lesions and maintenance of chronic disease is critical for the development of targeted therapeutics. OBJECTIVES We sought to characterize the mechanisms underlying the onset and maintenance of AD. METHODS We investigated intrapersonal sets of transcriptomes from nonlesional skin and acute and chronic lesions of 10 patients with AD through genomic, molecular, and cellular profiling. RESULTS Our study associated the onset of acute lesions with a striking increase in a subset of terminal differentiation proteins, specifically the cytokine-modulated S100A7, S100A8, and S100A9. Acute disease was also associated with significant increases in gene expression levels of major T(H)22 and T(H)2 cytokines and smaller increases in IL-17 levels. A lesser induction of T(H)1-associated genes was detected in acute disease, although some were significantly upregulated in chronic disease. Further significant intensification of major T(H)22 and T(H)2 cytokines was observed between acute and chronic lesions. CONCLUSIONS Our data identified increased S100A7, S100A8, and S100A9 gene expression with AD initiation and concomitant activation of T(H)2 and T(H)22 cytokines. Our findings support a model of progressive activation of T(H)2 and T(H)22 immune axes from the acute to chronic phases, expanding the prevailing view of pathogenesis with important therapeutic implications.

Abstract
Interferon (IFN)-γ is a cytokine with immunomodulatory properties, which has been shown previously to enhance the generation of tolerogenic dendritic cells (DC) when administered early ex vivo in 7-day monocyte-derived DC culture. To generate tolerogenic DC rapidly within 48 h, human monocytes were cultured for 24 h with interleukin (IL)-4 and granulocyte-macrophage colony-stimulating factor (GM-CSF) in the presence (IFN-γ-DC) or absence of IFN-γ (500 U/ml) (UT-DC). DC were matured for 24 h with TNF-α and prostaglandin E(2) (PGE(2) ). DC phenotype, signal transducer and activator of transcription-6 (STAT-6) phosphorylation and promotion of CD4(+) CD25(+) CD127(neg/low) forkhead box P3 (FoxP3)(hi) T cells were analysed by flow cytometry. DC nuclear factor (NF)-κB transcription factor reticuloendotheliosis viral oncogene homologue B (RELB) and IL-12p70 protein expression were also determined. Phenotypically, IFN-γ-DC displayed reduced DC maturation marker CD83 by 62% and co-stimulation molecules CD80 (26%) and CD86 (8%). IFN-γ treatment of monocytes inhibited intracellular STAT6, RELB nuclear translocation and IL-12p70 production. IFN-γ-DC increased the proportion of CD4(+) CD25(+) CD127(neg/low) foxp3(hi) T cells compared to UT-DC from 12 to 23%. IFN-γ-DC primed T cells inhibited antigen-specific, autologous naive T cell proliferation by 70% at a 1:1 naive T cells to IFN-γ-DC primed T cell ratio in suppression assays. In addition, we examined the reported paradoxical proinflammatory effects of IFN-γ and confirmed in this system that late IFN-γ exposure does not inhibit DC maturation marker expression. Early IFN-γ exposure is critical in promoting the generation of regulatory DC. Early IFN-γ modulated DC generated in 48 h are maturation arrested and promote the generation of antigen-specific regulatory T cells, which may be clinically applicable as a novel cellular therapy for allograft rejection.

Abstract
Eotaxin-3/CCL26 is an agonist for chemokine receptor 3 (CCR3) and a natural antagonist for CCR1, CCR2 and CCR5. CCL26 expression by non-haematopoietic cells has been well documented; however, no studies to date have demonstrated CCL26 expression by leucocytes. In this study, we investigated the ability of human monocytic cells to produce CCL26 in response to cytokines. We found that interleukin-4 (IL-4) increased the expression of CCL26 messenger RNA (mRNA) and protein in U937 cells, in human monocytes and in human monocyte-derived macrophages. Tumour necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) alone did not induce CCL26 expression, yet these pro-inflammatory cytokines synergized with IL-4 to increase CCL26 protein expression. Signal transducer and activator of transcription 6 (STAT6) was not affected by costimulation with TNF-alpha, suggesting that the synergy between IL-4 and TNF-alpha occurs at a step downstream of STAT6 activation. Co-incubation of interferon-gamma (IFN-gamma) with IL-4 had no effect on CCL26 protein release. By contrast, pretreatment with IFN-gamma decreased total STAT6 protein, blocked IL-4-mediated STAT6 phosphorylation and decreased IL-4-mediated CCL26 mRNA expression and protein release. These data show that IL-4 and pro-inflammatory cytokines such as TNF-alpha, IL-1beta and IFN-gamma regulate CCL26 synthesis in human monocytic cells, which may be important in regulating monocyte inflammatory responses.

Abstract
Monocytes play a central role in the immune system by producing and reacting to different soluble factors. Cytokine dysregulation is an hallmark in HIV-infected individuals and it is one of the most significant factors leading to impaired immunity in HIV/AIDS disease. This study investigates the possibility of modulation in the secretion of some inflammatory cytokines and chemokines induced by HIV p17 in monocytes. The results show that p17, while ineffective on resting monocytes, exerts an inflammatory action on IL-4 mediated inhibition of TNF-alpha and IFN-gamma production induced by IL-15 stimulation. In addition, p17 is able to reduce MIP-1alpha secretion, but unable to influence IL-6 production. The ability of HIV p17 to contribute to an altered pattern of secreted soluble factors might imply a key role for this viral protein in the development of AIDS pathogenesis.

Abstract
The activating and inhibitory cytokine signals that act upon epithelial cells in the human lung are critically important for controlling the production of inflammatory mediators from those cells in the context of allergic disease. The cytokines interleukin (IL)-4 and IL-13, derived from T helper (Th)-2 cells and other cell types, are potent inducers of epithelial cell expression of a host of inflammatory molecules, including the chemokines eotaxin-1, -2 and -3. Intracellular signal transduction in response to IL-4/IL-13 occurs largely through activation of signal transducer and activator of transcription 6 (STAT6). Interferon (IFN)-gamma, a Th1-type cytokine, has opposing effects to IL-4/IL-13 in various cell types, including T cells, B-cells, endothelium, and epithelium. In this study, we demonstrate that IL-4-induced STAT6 activation was inhibited profoundly by 24 h pretreatment with IFN-gamma in human primary airway epithelial cell cultures. Using Western blotting, we showed that the levels of both cytoplasmic and nuclear-localized phospho-STAT6 were reduced by IFN-gamma pretreatment, and this effect was dependent on the concentration of IFN-gamma and time of exposure to IFN-gamma. The functional activity of STAT6 was also completely inhibited by IFN-gamma: IL-4-induced luciferase activity from a STAT6-driven reporter construct was suppressed, as was IL-4-induced expression of messenger RNA (mRNA) and protein for eotaxin-3, a STAT6-dependent gene implicated in allergic inflammation. We found that mRNA for suppressor of cytokine signaling (SOCS)-1 and (SOCS)-3, known inhibitors of IL-4 signaling, and IL-13 receptor alpha2, a potential inhibitor of IL-4 signaling, were both strongly induced by IFN-gamma pretreatment. IFN-gamma also increased the rate of decay of IL-4-induced eotaxin-3 mRNA. We conclude that there are multiple mechanisms by which IFN-gamma regulates IL-4- and STAT6-dependent signaling and gene expression in airway epithelial cells. These observations have important implications for the regulation of epithelial cell activation by the balance of Th1/Th2-type cytokines in the airways in allergic disease.
