Description
This study demonstrates that arthritis and heart valve stenosis comorbidity, the most common condition among RA and SpA patients, share common mesenchymal requirements converging in the pathogenic activation of resident mesenchymal origin fibroblasts in the Tnf?ARE mouse model. TNFR2 signaling, in this context, orchestrates the molecular mechanisms underlying arthritis and heart valve stenosis manifestation by regulating fibroblasts pathogenic activation status, cell proliferation and pro-inflammatory milieu. Finally this work highlights the complexity of TNFR2 functions since mesenchymal signaling is detrimental, whereas systemic TNFR2 provides protective signals that contain both pathologies Overall design: 3' RNA-Seq (QuantSeq) profiling of 2 cell types (SFs,VICs) in two different genotypes (TNF-DeltaARE, ColVIp75f/f-TNF-DeltaARE) and Wild type as control. 3 replicates per group.

Description
Lung adenocarcinoma (LUAD)-derived oncogenic Wnts increase cancer cell proliferative/stemness potential, but whether they also impact the immune microenvironment is unknown. Here we show that LUAD cells use paracrine Wnt1 signaling to induce immune resistance. Wnt1 correlated strongly with tolerogenic genes on the TCGA expression data. In another cohort, Wnt1 was inversely associated with T cell abundance. Altering Wnt1 expression profoundly affected growth of murine lung adenocarcinomas and this was strongly dependent on conventional dendritic cells and T cells. Mechanistically, Wnt1 lead to transcriptional silencing of CC/CXC chemokines in dendritic cells and T cell cross-tolerance. Wnt-target genes were up-regulated in human intratumoral dendritic cells and decreased upon silencing Wnt1, accompanied by enhanced T cell cytotoxicity. siWnt1-loaded nanoparticles as single therapy or part of combinatorial immunotherapies acted at both arms of the cancer-immune ecosystem to halt tumor growth. Collectively, our studies show that Wnt1 enhances adaptive immune rejection of lung adenocarcinomas and highlight its potential targeting as a novel therapeutic strategy Overall design: RNAseq data of two DC subsets of 4 patients with lung adenocarcinomas (LUADs).

Description
This study showed that the oncogenic ligand Wnt1 silences chemokine genes in dendritic cells, leading to impaired cross-priming of T cells in lung adenocarcinoma. Blocking Wnt1 enhanced rejection of tumors by acting concomitantly at the cancer and immune cell level. Overall design: 3' RNA-Seq (QuantSeq) profiling of sorted cDCs populations from WNT1 overexpressing and control (Empty) lung tumors.

Description
Pluripotent stem cells, including human embryonic stem (hES) and induced pluripotent stem (hiPS) cells, have been regarded as useful sources for cell?based transplantation therapy. However immunogenicity of the cells remains the major determinant for successful clinical application. We report the examination of several hES cell lines (NTU1 and H9), hiPS cell lines, and their derivatives (including stem cell?derived hepatocytes) for the expression of major histocompatibility complex (MHC), natural killer (NK) cell receptor (NKp30, NKp44, NKp46) ligand, immune?related genes, human leukocyte antigen (HLA) haplotyping, and the effects in functional mixed lymphocyte reaction (MLR). Flow cytometry showed lower levels (percentages and fluorescence intensities) of MHC class I (MHC?I) molecules, 2?microglobulin and HLA?E in undifferentiated stem cells, but the levels were increased after co?treatment with interferon gamma and/or in vitro differentiation. Antigen presenting cell markers (CD11c, CD80 and CD86) and MHC?II (HLA?DP, DQ and DR) remained low throughout the treatments. Recognitions of stem cells/derivatives by NK lysis receptors were lower or absent. Activation of responder lymphocytes was significantly lower by undifferentiated stem cells than by allogeneic lymphocytes in MLR, but differentiated NTU1 hES cells induced a cell number?dependent lymphocyte proliferation comparable with that by allogeneic lymphocytes. Interestingly activation of lymphocytes by differentiated hiPS cells or H9 cells became blunted at higher cell numbers. Real?time RT?PCR showed significant differential expression of immune privilege genes (TGF?2, Arginase 2, Indole 1, GATA3, POMC, VIP, CALCA, CALCB, IL?1RN, CD95L, CR1L, Serpine 1, HMOX1, IL6, LGALS3, HEBP1, THBS1, CD59 and LGALS1) in pluripotent stem cells/derivatives when compared to somatic cells. It is concluded that pluripotent stem cells/derivatives are predicted to be immunogenic, though evidences suggest some levels of potential immune privilege. In addition, differential immunogenicity may exist between different pluripotent stem cell lines and their derivatives

Description
Sorafenib is the only approved targeted drug for hepatocellular carcinoma (HCC), but its effect on patients survival gain is limited and varies over a wide range depending on patho-genetic conditions. Thus, enhancing the efficacy of sorafenib and finding a reliable predictive biomarker are crucuial to achieve efficient control of HCCs. In this study, we employed a systems approach by combining transcriptome analysis of the mRNA changes in HCC cell lines in response to sorafenib with network analysis to investigate the action and resistance mechanism of sorafenib. Gene ontology and gene set analysis revealed that proteotoxic stress and apoptosis modules are activated in the presence of sorafenib. Further analysis of the endoplasmic reticulum (ER) stress network model combined with in vitro experiments showed that introducing an additional stress by treating the orally active protein disulfide isomerase (PDI) inhibitor (PACMA 31) can synergistically increase the efficacy of sorafenib in vitro and in vivo, which was confirmed using a mouse xenograft model. We also found that HCC patients with high PDI expression show resistance to sorafenib and poor clinical outcomes, compared to the low PDI expression group. These results suggest that PDI is a promising therapeutic target for enhancing the efficacy of sorafenib and can also be a biomarker for predicting sorafenib responsiveness.
