Characterization of IL-6R-expressing monocytes in the lung of patients with chronic obstructive pulmonary disease [IL-6 mono]

Project description:Background: Monocytes play a crucial role in innate immune responses for host defense, yet their involvement in chronic obstructive pulmonary disease (COPD) remains poorly understood. We previously identified a subset of monocytes in COPD lung tissues characterized by high interleukin-6 receptor (IL-6R) expression. This study aimed to characterize the phenotypes of IL-6Rhi monocytes in the lung of COPD patients. Methods: Using flow cytometry, we assessed the abundance of pulmonary CD14+IL-6Rhi cells in never smokers (CNS), control ex-smokers (CES) and COPD patients. IL-6 expression in CD14+ monocytes from peripheral blood of patients with COPD was also examined. CD45+CD206–CD14+IL-6Rhi and CD45+CD206–CD14+IL-6R– cells were isolated from COPD lung tissues for transcriptome analysis. A monocyte line THP1 cell with constitutive IL-6R expression was stimulated with recombinant IL-6, followed by RNA sequencing to evaluate IL-6 responsiveness of IL-6R+ monocytes. Results: The number of pulmonary CD14+IL-6Rhi monocytes was elevated in COPD patients compared to CNS, while CD14+ monocytes in the peripheral blood of COPD patients did not express IL-6R. Upregulated mRNA expression in CD14+IL-6Rhi monocytes was associated with chemotaxis, monocyte differentiation, fatty acid metabolism and integrin-mediated signaling pathway. Stimulation of THP1 cells with recombinant IL-6 induced gene expression changes linked to chemotaxis and organism development. Conclusion: In patients with COPD, CD14+IL-6Rhi monocytes increase in lung tissues compared to CNS and exhibit a different transcriptome profile from CD14+IL-6R– monocytes.

IL-6R identifies early differentiated human effector memory CD8+ T cells that potently expand and produce IL-2 and IL-13

Project description:We found a unique subset of effector memory (EM) CD8+ T cells that expressed high levels of IL-6 receptor in human peripheral blood. These cells which also expressed high levels of IL-7Ra (referred to as IL-6R high IL-7Rahigh cells) had the a distinct gene expression profile and cellular characteristics compared to other EM CD8+ T cells. IL-6R high IL-7Ra high cells were early differentiated EM CD8+ T cells with decreased expression of T-bet, KLRG1, perforin and granzyme B. These cells had increased cell proliferation likely secondary to enhanced IL-2 production and high affinity IL-2R expression. IL-6R high IL-7Ra high EM CD8+ T cells exclusively produced high levels of IL-2, IL-5, IL-9 and IL-13 although IFN-r was produced by this cell subset and other EM CD8+ T cells. Of interest, IL-6R high IL-7Ra high EM CD8+ T cells expanded in the peripheral blood of patients with chronic obstructive pulmonary disease (COPD) and asthma where CD8+ T cells, IL-13 and IFN-r are suggested to be involved in the pathogenesis. Being the early-differentiated EM CD8+ T cells with a potent capacity to proliferate, survive and generate multiple cytokines, IL-6R high IL-7Ra high EM CD8+ T cells may serve as a primary reservoir for effector CD8+ T cells which potently expand and produce cytokines upon immune stimulation. Duplicate experiments were performed for each condition. In each condition, we independently prepared total RNA using the RNeasy mini kit (Qiagen) and assessed RNA integrity using Bioanalyzer 2100 (Agilent)- RINs were close to 10 for all samples. RNA was then amplified and hybridized to the Illumina HumanHT-12 v4.0 BeadChip, according to Illumina standard protocols.

Ets-2 propagates IL-6 trans-signaling mediated osteoclast-like changes in human rheumatoid arthritis synovial fibroblast

Project description:Interleukin-6 (IL-6) plays an important role in progressive bone loss in rheumatoid arthritis (RA). However, the molecular mechanisms through which IL-6 propels RA synovial fibroblasts (RASFs) to contribute to bone loss are not fully understood. In the present study, we investigated the effects of IL-6 and IL-6 receptor (IL-6/IL-6R induced trans-signaling in human RASFs. Treatment of human RASFs with IL-6 and IL-6 receptor (IL-6/IL-6R, 100 ng/ml each) alone or in combination with M-CSF (2 ng/ml) and RANKL (10 ng/ml) for 12 days resulted in the phenotypic changes to osteoclast-like features as determined by increase in TRAP staining and enhanced pit formation by ~3-fold in bone resorption assay in vitro. IL-6/IL-6R induced a dose-dependent increase in the expression of transcription factor Ets2 and enhanced its nuclear translocation in human RASFs. Interestingly, the untargeted proteomics analysis of the conditioned media from IL6/IL6R activated RASFs using Mass-Spectrometry (MS) technique and Trans-Proteomic Pipeline tool showed the production of 113 analytes unique to IL-6/IL-6R stimulation. Further analysis of the proteomics data using STRING database for pathway analysis showed the impact of IL-6/IL-6R on immunometabolic reprogramming of human RASFs towards osteoclast-like phenotype, which was partly mediated through Ets2. These preliminary studies identified a novel role of IL-6/IL-6R-mediated trans signaling in the metabolic reprogramming in RASFs that could potentially be targeted by inhibiting Ets2 to limit their role in bone resorption in RA.

Increased IL-6 Trans-Signaling in the Airways After an Allergen Challenge

Project description:The pro-inflammatory cytokine IL-6 is elevated in both blood and airways in asthma. IL-6 signaling is regulated by its receptor composed of two proteins, IL-6R and GP130, that are found in both membrane and soluble forms. The interaction of IL-6 with soluble IL-6R (sIL-6R) can trigger IL-6 trans-signaling in cells such as epithelial cells and fibroblasts, which express GP130, but do not produce sufficient IL-6R. We aimed to analyze IL-6 trans-signaling in the airways after an allergen challenge and to examine the potential source of sIL-6R and sGP130. In addition to protein analysis of bronchoalveolar lavages by ELISA and flow cytometry, we performed next-generation RNA sequencing (RNA-seq) to study the expression of the IL-6R subunits by eosinophils activated by IL-3 in vitro. RNA-seq and proteomic analyses confirmed that eosinophils do not produce GP130 but produce both IL-6R and ADAM10, a metalloproteinase that cleaves membrane IL-6R into sIL-6R.
