Project description:I IFNs promote differentiating monocytes to differentiate into tumor-associated macrophages (TAMs) and limit the I IFNs anti-tumor effects.But how macrophage polarization is shaped by complex signals in the tumor microenvironment during IFN therapies is incompletely understood. Herein, it was discovered that I IFNs could stimulate transitional monocytes to secrete interleukins IL-4 and IL-6, which interact to influence target genes expression in primary mouse bone-marrow-derived macrophages (BMDMs). To analyze the synergism mechanism, RNA seq was performed. Bone marrow derived macrophages were cultured under the 20ng/ml M-CSF for 7days, and treated with the indicated cytokine, samples were harvested for total RNAs and subjected to RNA sequencing analyses.

Project description:Interleukin 9 (IL-9) is a γc-family cytokine that is highly produced by T-helper 9 (Th9) cells and regulates a range of immune responses, including allergic inflammation. Here we show that IL-2–JAK3–STAT5 signaling is required for Th9 differentiation, with critical STAT5 binding sites in the Il9 (the gene encoding IL-9) promoter. IL-2 also inhibited B cell lymphoma 6 (BCL6) expression, and over- expression of BCL6 impaired Th9 differentiation. In contrast to IL-2, IL-21 induced BCL6 and diminished IL-9 expression in wild-type but not Bcl6−/− cells, whereas Th9 differentiation was increased in Il21−/− or Il21r−/− T cells. Interestingly, BCL6 bound in proximity to many STAT5 and STAT6 binding sites, including at the Il9 promoter. Moreover, there was increased BCL6 and decreased STAT binding at this site in cells treated with blocking antibodies to IL-2 and the IL-2 receptor, suggesting a possible BCL6–STAT5 binding competition that influences IL-9 production. BCL6 binding was also increased when cells were Th9-differentiated in the presence of IL-21. Thus, our data reveal not only direct IL-2 effects via STAT5 at the Il9 gene, but also opposing actions of IL-2 and IL-21 on BCL6 expression, with increased BCL6 expression inhibiting IL-9 production. These data suggest a model in which increasing BCL6 expression decreases efficient Th9 differentiation, indicating possible distinctive approaches for controlling this process. Genome-wide transcription factors mapping and binding of STAT5B and STAT6 in mouse polarized Th9 cells treated with or without blocking antibodies to IL-2 (anti-IL-2). RNA-Seq is conducted in WT and Il2-/- mice.

Project description:Background: Skewing root patterns provide key insights into root growth strategies and mechanism that produce root architectures Roots exhibit skewing and waving when grown on a tilted, impenetrable surface, and while the genetics guiding these morphologies have been examined, the underlying molecular mechanisms of skewing and waving remain unclear. In this study, transcriptome data were derived from two Arabidopsis ecotypes, WS and Col-0, under three tilted growth conditions in order to identify candidate genes involved in skewing. WS is a skewing ecotype. Col-0 is a non-skewing ecotype. Results: This work identifies a number of genes that are likely involved in skewing, using growth conditions that differentially affect skewing and waving. Comparing the gene expression profiles of WS and Col-0 in different tilted growth conditions identified 11 candidate genes as potentially involved in the control of skewing. These 11 genes are involved in several different cellular processes, including sugar transport, salt signaling, cell wall organization, and hormone signaling. Conclusions: Many of the 11 identified genes are involved in signaling and perception, rather than the physical restructuring of roots, leading to the conclusion that root skewing is enabled through diverse environmental signaling pathways. These findings revealed further insights into the molecular mechanisms behind root skewing. This work investigated the transcriptional differences between skewing and non-skewing roots. Comparisons within WS revealed gees that that responded to the angle of growth (Agp) during the process of skewing. These genes were cross referenced with transcripts differing between the WS and Col-0 genotypes to refine the list of genes that are most probably be involved in root skewing. More of the highly probable skew gene candidates (HPSGC) are associated with environmental sensing (e.g. salt, sugar, hormones, darkness) than with physical growth differences (e.g. cell wall remodeling, cell division, cell elongation). Thus, the root behavior of skewing appears to be primarily driven by pathways that respond to disparate signals from the root local environment. Future studies could investigate the HPSGC to find the specific pathways and molecular mechanisms contributing to root skewing.

Project description:The common gamma chain (γc) is required for productive signaling by interleukin (IL)-15, IL-21 and IL-2, which are critically involved in immune activation and regulation. IL-21 and IL-15 are implicated in the pathogenesis of type-1 diabetes, graft-versus-host disease, and celiac disease (CeD), a gluten-mediated autoimmune-like enteropathy. Attempts to treat type-1 diabetes and graft-versus-host disease with biologics targeting one particular cytokine have failed. Both IL-15 and IL-21 have been suggested to drive activation of cytotoxic T cells (CTL) that are the effectors mediating tissue destruction in CeD and organ-specific autoimmune disorders. We show that the concomitant upregulation of IL-15 and IL-21 occurs only in full-blown CeD with villous atrophy. BNZ-2, a peptide that targets the γc, was able to block the cooperative IL-15/IL-21 mediated transcriptional activation of human tissue-resident intraepithelial CTL. Importantly, this inhibition was specific and did not interfere with IL-2 signaling, a cytokine with known immunoregulatory functions. Moreover, BNZ-2 blocked gluten-induced IFN-γ production in small intestinal organ cultures from CeD patients. These observations identify BNZ-2 as a therapeutic candidate for immune disorders in which IL-15 and IL-21 cooperate to induce CTL-mediated tissue damage.

Project description:Objective Ulcerative colitis (UC) is a risk factor of periodontitis. This study aimed to investigate whether hematopoietic stem and progenitor cells (HSPCs) and their myeloid progeny exacerbate periodontal inflammation in UC. Design Ligature-induced periodontitis (LIP) was established in dextran sulfate sodium (DSS)-induced colitis (DIC) C57BL/6 mice. The bone resorption, intestinal and periodontal inflammation were evaluated by micro-CT and histological analyses. Inflammatory cytokines and lipopolysaccharide (LPS) in serum and gut microbiota were assessed by multiplexed flow cytometric assay, ELISA and 16S rRNA sequencing, respectively. Flow cytometry was performed to analyze HSPCs differentiation, and to sort hematopoietic stem cells for transcriptomic analysis. Berberine treatment of DIC was employed to investigate whether dampening of DIC would alleviate periodontitis. Results DIC mice exhibited disrupted intestinal barrier with dysbiotic gut microbiota, corroborating the elevated serum level of LPS and IL-1. Compared to DIC-free/LIP mice, DIC/LIP mice showed aggravated alveolar bone resorption, with enrichment of neutrophils extracellular traps (NETs) in periodontal tissues. DIC promoted myelopoiesis of HSPCs by up-regulating myeloid differentiation pathway. Intragastric administration of berberine dampened DIC and rescued the myeloid skewing of HSPCs, consequently alleviating periodontal destruction. Intriguingly, LIP induction after DIC remission still exhibited aggravated periodontal destruction and myeloid skewing of HSPCs, indicating a UC-trained immunity against periodontal infection. Conclusion Increased gut permeability and microbial dysbiosis in UC elevate the serum level of LPS and IL-1, inducing myeloid skewing of HSPCs with an immune memory. Generation of inflammatory potential myeloid cells causes NETs accumulation and aggravates periodontal destruction in the UC-related periodontitis.

Project description:Interleukin-1 (IL-1) is a key pro-inflammatory cytokine, which has diverse actions in the brain as a regulator of host defence responses and a mediator of inflammation. Two major agonists, IL-1α and IL-1β bind to a single known functional (type-1) IL-1 receptor (IL-1RI), which associates with an accessory protein (IL-1RAcP) leading to signal transduction. However, recent evidence suggests that some actions of IL-1 in the brain may be independent of IL-1R1 and its classical signalling pathways, pointing to an as yet unidentified functional receptor for IL-1 expressed in the CNS. In this study, cDNA array based gene expression profiling was used to identify possible genes induced by IL-1β independently of IL-1R1. The results show that IL-1β may indeed regulate some genes independently of IL-1R1, suggesting the presence of additional functional IL-1 receptors in the mouse brain.
