Cytokimera GIL-11 rescued IL-6R deficient mice from partial hepatectomy-induced death by signaling via non-natural gp130:LIFR:IL-11R complexes

ABSTRACT: All except one cytokine of the Interleukin (IL-)6 family share glycoprotein (gp) 130 as the common b receptor chain. Whereas Interleukin (IL-)11 signal via the non-signaling IL-11 receptor (IL-11R) and gp130 homodimers, leukemia inhibitory factor (LIF) recruits gp130:LIF receptor (LIFR) heterodimers. Using IL-11 as a framework, we exchange the gp130 binding site III of IL-11 with the LIFR binding site III of LIF. The resulting synthetic cytokimera GIL-11 efficiently recruits the non-natural receptor signaling complex consisting of gp130, IL-11R and LIFR resulting in signal transduction and proliferation of factor-depending Ba/F3 cells. Besides LIF and IL-11, GIL-11 does not activate receptor complexes consisting of gp130:LIFR or gp130:IL-11R, respectively. Human GIL-11 shows cross-reactivity to mouse and rescued IL-6R deficient mice following partial hepatectomy, demonstrating gp130:IL-11R:LIFR signaling efficiently induced liver regeneration. With the development of the cytokimera GIL-11, we devise the functional assembly of the non-natural cytokine receptor complex of gp130:IL-11R:LIFR.

Oncostatin M (OSM) and Leukemia Inhibitory factor (LIF) treatment of osteoblasts via LIF and OSM receptors

Project description:Oncostatin M (OSM) and Leukemia Inhibitory Factor (LIF) signal within cells via the gp130 (Il6st) coreceptor bound either to the LIF receptor (LIFR) or the oncostatin M receptor (OSMR), but whether murine OSM can act through both receptors is controversial. Both LIF and OSM stimulate bone formation, inhibit adipocyte differentiation, and promote osteoclast differentiation, but our earlier work suggested this may depend on the receptor subtype used. This project aimed to identify those gene targets regulated by murine OSM via OSMR and LIFR by using wild type and OSMR null primary osteoblasts. Cells were differentiated to their most mature state (i.e. osteocytes) because the only prior target gene known to be regulated by murine OSM via the LIFR was an osteocyte-specific gene, sclerostin.

Oncostatin M Regulation of Gene Expression in Breast Tumour Cells.

Project description:Oncostatin m (OSM) induces potent growth inhibitory and morphogenic responses in several different tumour cell types but the genetic events are not well understood. OSM can signal through two separate heterodimeric receptor complexes, gp130/LIFRα and gp130/OSMRβ. In this investigation we utilised cytokines, oncostatin M, interleukin-6 (IL-6) and leukaemia inhibitory factor (LIF) and LIF receptor antagonist, LIF-05, to help identify patterns of gene expression elicited by the different IL-6 receptor complexes in breast tumour cell line, T47D . We have tried to identify an OSM gene signature common to multiple breast tumour-derived cell lines (T47D, MCF-7 and MDA-MB-231) and identified OSM-gene regulation at time-points which coincide with the onset of OSM-induced biological effects. These findings identify a core transcriptional mechanism specific to the OSMRβ in breast tumour cells. Keywords: Comparative, timecourse, cell line-specific

IL-11 induces NLRP3 inflammasome activation

Project description:The objective of this study is to examine IL-11-induced mechanisms of inflammatory cell migration to the CNS. We report that IL-11 is produced at highest frequency by myeloid cells among the PBMC cell subsets. Patients with relapsing-remitting multiple sclerosis (RRMS) have an increased frequency of IL-11+ monocytes, IL-11+ and IL-11R+ CD4+ lymphocytes and IL-11R+ neutrophils in comparison to matched healthy controls (HCs). IL-11+ and GM-CSF+ monocytes, CD4+ lymphocytes, and neutrophils accumulate in the cerebrospinal fluid (CSF). The effect of IL-11 in-vitro stimulation, examined using single cell RNA sequencing (scRNAseq), revealed the highest number of differentially expressed genes (DEGs) in classical monocytes, including upregulated NFKB1, NLRP3 and IL1B. All CD4+ cell subsets had increased expression of S100A8/9 alarmin genes involved in NLRP3 inflammasome activation. In IL-11R+-sorted cells from the CSF, classical and intermediate monocytes significantly upregulated the expression of multiple NLRP3 inflammasome-related genes, including complement, IL18, and migratory genes (VEGFA/B) in comparison to blood-derived cells. Therapeutic targeting of this pathway with aIL-11 mAb in mice with RR experimental autoimmune encephalomyelitis (EAE) decreased clinical scores, CNS inflammatory infiltrates and demyelination. aIL-11 mAb treatment decreased the numbers of NFkBp65+, NLRP3+ and IL-1b+ monocytes in the CNS of mice with EAE. The results suggest that IL-11/IL-11R signaling in monocytes represents a therapeutic target in RRMS.

Synthetic IL-22 signaling revealed biological activity of homodimeric IL-10 receptor 2 and functional cross-talk with the IL-6 receptor gp130

Project description:Cytokine signaling is transmitted by cell surface receptors which function as natural biological switches to control among others mainly immune related processes. Recently, we have designed synthetic cytokine receptors (SyCyRs) consisting of GFP- and mCherry-nanobodies fused to trans-membrane and intracellular domains of cytokine receptors, which phenocopied cytokine signaling induced by non-physiological homo- and heterodimeric GFP-mCherry ligands. Interleukin 22 signals via IL-22Rα1 and the common IL-10R2, belongs to the IL-10 cytokine family and is critically involved in tissue regeneration. IL-22 SyCyRs phenocopied native IL-22 signal transduction as shown by induction of cytokine-dependent cellular proliferation, signal transduction and transcriptome analysis. Whereas homodimeric IL-22Rα1 SyCyRs failed to activate signaling, homodimerization of the second IL-22 signaling chain, SyCyR(IL-10R2), which was considered to not induce signal transduction, lead to induction of signal transduction. Interestingly, the SyCyR(IL-10R2) and SyCyR(IL-22Rα1) were able to form functional heterodimeric receptor signaling complexes with the synthetic IL-6 receptor chain SyCyR(gp130). In summary, we demonstrated that IL-22 signaling can be phenocopied by synthetic cytokine receptors. Further we identified a novel IL-10R2 homodimeric receptor complex and receptor cross-talk with gp130.

Epithelial LIF signaling limits apoptosis and lung injury during bacterial pneumonia

Project description:During bacterial pneumonia, alveolar epithelial cells are critical for maintaining gas exchange and providing antimicrobial as well as pro-immune properties. We previously demonstrated that leukemia inhibitory factor (LIF), an IL-6 family cytokine, is produced by type II alveolar epithelial cells (ATII) and is critical for tissue protection during bacterial pneumonia. However, the target cells and mechanisms of LIF-mediated protection remain unknown. Here, we demonstrate that antibody-induced LIF blockade remodels the lung epithelial transcriptome in association with increased apoptosis. Based on these data, we performed pneumonia studies using a novel mouse model in which LIFR (the unique receptor for LIF) is absent in lung epithelium. While LIFR was detected on the surface of epithelial cells, its absence only minimally contributed to tissue protection during pneumonia. Single-cell RNA-sequencing (scRNAseq) was conducted to identify adult murine lung cell types most prominently expressing LIFR, revealing endothelial cells, mesenchymal cells, and ATIIs as major sources of LIFR. Sequencing data indicated that ATII cells were significantly impacted as a result of pneumonia, with additional differences observed in response to LIF neutralization, including but not limited to gene programs related to cell death, injury, and inflammation. Overall, our data suggest that LIF signaling on epithelial cells alters responses in this cell type during pneumonia. However, our results also suggest separate and perhaps more prominent roles of LIFR in other cell types, such as endothelial cells or mesenchymal cells, which provide grounds for future investigation.

2-DG protects mouse from DSS-induced inflammatory bowel disease

Project description:Anti-proinflammatory cytokine therapies against interleukin (IL)-6 and tumor necrosis factor (TNF)-a are major advances in treating inflammatory diseases. We found that 2-deoxy-D-glucose (2-DG), a simple monosaccharide, attenuated IL-6 responses by inhibiting N-linked glycosylation of the IL-6 receptor gp130. Aglyco forms of gp130 failed to bind IL-6 and to activate downstream signals. 2-DG completely inhibited dextran sodium sulfate-induced inflammatory bowel disease that was partially dependent on IL-6.

Oncostatin M maintains naïve pluripotency of mESCs by tetraploid embryo complementation (TEC) assay

Project description:It has been well established that (LIF) is essential for maintaining naive pluripotency of ESCs. Oncostatin M (OSM) is a member of the IL-6 family of cytokines which share gp130 as a receptor subunit, and the OSM-gp130 complex can recruit either LIF receptor β or OSM receptor β. Here we show that OSM can completely replace LIF to maintain naive pluripotency of mouse ESCs. Mouse ESCs cultured in the presence of LIF or OSM not only express pluripotency genes at similar levels but also exhibit the same developmental pluripotency as evidenced by generation of germline competent chimeras, supporting previous findings. Moreover, we demonstrate that mESCs cultured in OSM produce viable all-ESC pups by tetraploid embryo complementation (TEC) assay, the most stringent functional test of authentic pluripotency. Furthermore, the telomere length and telomerase activity also are crucial for unlimited self-renewal and genomic stability of mESCs, and these do not differ in mESCs cultured under OSM or LIF. The transcriptome of mESCs cultured in OSM overall is very similar to that of LIF, and OSM activates Stat3 signaling pathway, like LIF. Additionally, OSM upregulates pentose and glucuronate interconversions, ascorbate and aldarate metabolism, steroid and retinol metabolism pathways. Although the significance of these pathways remains to be determined, our data shows that OSM can maintain the naive pluripotent stem cells in the absence of LIF.

Genome-wide analysis of interleukin (IL) -6 and IL-11 responsive genes in murine gastric tumors

Project description:We performed micrarrays to analyse gene expression in spontaneously arising gastric tumors from gp130Y757F/F mutant mice (Tebbutt et al., 2002) following administration of recombinant human IL-6 or IL-11. The present study was designed to assess differences in gene expression in response to IL-6 and IL-11, two cytokines which both activate the shared gp130 receptor and downstream Stat3 signalling pathway. Since gastric tumorigenesis in gp130Y757F/F mice is strictly dependent on IL-11, but not IL-6 signalling (Ernst et al., 2008) the study aimed to identify IL-6 and IL-11 specific target genes which may account for the IL-11 dependent tumor development. Total RNA was obtained from gastric tumor tissue of gp130Y575F/F mice collected 60 min after a single systemic (i.p.) administration of PBS (vehicle control), recombinant human IL6 or IL11 (5 ug). The gene expression profile of the IL-6 and IL-11 treated samples were separately compared to the PBS (vehicle) treated control samples, resulting in two lists of responsive genes (”IL-6 vs control” and “IL-11 vs control”).
