Gene expression data from NECA (5/-N-ethylcarboxamidoadenosine) treated murine pituitary folliculostellate cells(TtT/GF)

ABSTRACT: Folliculostellate cells constitute as much as 10% of the cells within the anterior pituitary gland; they however do not secrete any of the classical hormones but do express cytokines and growth factors. The endogenous nucleoside adenosine can be either pro- or anti-inflammatory depending on receptor expression and the activation of one or more receptors A1, A2a, A2b and A3. Adenosine stimulates the secretion of immune molecules from folliculostellate; these cells appear to mediate communication between the endocrine and immune systems. Replicate (x3) cultures of TtT/GF cells were treated with 10µM NECA (5/-N-ethylcarboxamidoadenosine) for 30 and 120 minutes. RNA was extracted, cRNA prepared and hybridized to murine MG_U74A v2 GeneChip (Affymetrix), changes in expression were compared with untreated controls.

Expression data from Germ-Free (GF) and L.NK2-colonized mice intestinal epithelial cells and Peyer's patches cells

Project description:Lactobacillus NK2 (L.NK2) is a commensal microbe, isolated from the mouse intestinal feces in our lab. To examine the potential role of L. NK2 in the gut immunity, we monocolonized GF mice with L.NK2. And, we conducted a microarray experiment to compare the transcriptomes of GF and L.NK2-colonized mice intestines under the same experimental condition We used microarrays to detail the global programme of gene expression in intestinal epithelial cells (IEC) and Peyer's patches cells (PP) of GF and L.NK2-colonized mice.

Adenosine uptake through equilibrative nucleoside transporter-1 suppresses antitumor immunity by pyrimidine starvation

Project description:Immunosuppression by adenosine is an important cancer immune checkpoint. Extracellular adenosine signals through specific receptors and can be transported across the cell membrane through nucleoside transporters. While adenosine receptors are well-known to regulate tumor immunity, the impact of adenosine transporters remains unexplored. In this study, we investigated the effect on tumor immunity of equilibrative nucleoside transporter-1 (ENT1), the major regulator of extracellular adenosine concentrations. Using selective inhibitors and gene targeting approaches, we demonstrated that blocking or deleting host ENT1 significantly enhanced CD8+ T cell-dependent anti-tumor responses. Tumors inoculated into ENT1-deficient mice showed increased infiltration of effector CD8+ T cells with an enhanced cytotoxic transcriptomic profile and significant upregulation of granzyme B, IFN-g, IL-2, TNF-a and CXCL10. ENT1-deficiency was further associated with decreased tumor-infiltrating T regulatory cells and CD206high macrophages, and suppressed CCL17 production. ENT1-deficiency notably potentiated the therapeutic activity of PD-1 blockade. T cells upregulated ENT1 upon activation, and blocking ENT1 enhanced their function when co-cultured with cognate antigen/HLA-matched melanoma cells. Mechanistically, ENT1-mediated adenosine uptake inhibited the activity of phosphoribosylpyrophosphate synthetase (PRPS) in activated T cells, thereby suppressing production of uridine 5′-monophosphate (UMP) and its derivatives required for DNA and RNA synthesis. In summary, our study identified ENT1-mediated adenosine uptake as an important and previously unappreciated mechanism of adenosine-mediated immunosuppression via pyrimidine starvation that can be targeted to enhance antitumor T cell responses.

The transcriptome profiling analysis of intestines and kidneys in conventionally raised (CV) and germ-free (GF) wild type zebrafish embryos

Project description:To investigate how the zebrafish embryos respond to the absence of the microbiota, the intestinal tissue-associated and the kidney tissue-associated gene expressions were examined at 5 dpf and 7 dpf respectively. 32,948 cDNAs of the zebrafish genome assembly were annotated after reads mapping for further analysis. For the 5 dpf intestinal tissue samples, 948 genes (4% of the total number of genes) were differentially expressed, 371 genes were up-regulated and 577 genes were down-regulated in the GF group . For the 7 dpf kidney tissue samples, 697 genes (3% of the total number of genes) were differentially expressed, 341 genes were up-regulated and 356 genes were down-regulated in the GF group. The enrichment analysis showed that the immune and cytokine related pathways were affected by the GF treatment in the wildtype embryos (both in intestines at 5 dpf and in kidneys at 7 dpf). To investigate how the transcriptome changes in the chd8-/- zebrafish embryos, the intestinal tissue-associated and the kidney tissue-associated gene expressions were examined at 5 dpf and 7 dpf respectively.
