Development of gene expression signatures on immunity for bursal peptide BSP-II

ABSTRACT: To further elucidate the mechanism of BSP-II on immunity on the broad molecular level, we have employed whole genome microarray expression profiling as a discovery platform to examine gene expression patterns during BSP-II treatment in a mouse derived hybridoma culture system. Hybridoma cell was treated ex vivo, and robust normalization of the data identified 1279 differentially expressed probe sets exhibiting minimum 1.5-fold changes that distinguished between BSP-II and control samples. Various pathwayswere significantly impacted by BSP-II treatment, and gene Ontology annotations show changes in the expression of molecules involved in immune and immunocyte related cellular processes. Expression of nine genes (MS4A2, CD3D, FGF21, CD80, PTPRC, NFATC4, IL2RB, Fas and LAT) from this signature was quantified in the RNA samples by QRT-PCR, confirming low variability between the predicted response patterns. BSP-II induced gene expression in hybridoma cell was measured at 4 hours after exposure to doses of 0ug/ml and 5ug/ml. Two independent experiments were performed using different cells for each experiment.

Profile of gene expression signatures on DT40 cell for bursal-derived peptides

Project description:To further elucidate the mechanism of bursal-derived bioactive peptides on avian B cell proliferation on the broad molecular level, we have employed whole genome microarray expression profiling as a discovery platform to examine gene expression patterns during BP5 and BSP-II treatment in DT40 cell culture system. Analysis of our expression microarray data in this manner defined 3163 genes up-regulated and 3539 genes down-regulated by BP5 treatment and 3117 genes up-regulated and 3531 genes down-regulated by BSP-II treatment at 95% confidence, with a commonly regulated gene set of 2253 upregulated genes and 2083 downregulated genes. Various pathways were significantly impacted by BP5 and BSP-II treatment, and gene Ontology annotations show changes in the expression of molecules involved in DT40 cell with BP5 and BSP-II treatment. Expression of 12 genes (FGF3, RAP1B, TCEB1, CSNK2A1, DNMT1, HIF1A, HDAC1, FZR1, GDF3, FGF8, IRF7, and SKP1) from this signature was quantified in the RNA samples by QRT-PCR, confirming low variability between the predicted response patterns. BP5 and BSP-II induced gene expressions in DT40 cell were measured at 4 hours after exposure to doses of 0.02ug/ml and 2ug/ml, respectively. Two independent experiments were performed using different cells for each experiment.Three independently generated populations of cells were used for these experiments.

Dexamethasone treatment of 3B4.15 T hybridoma cells

Project description:Investigation of whole genome gene expression level changes in Mus musculus 3B4.15 T hybridoma cells treated with 1microMolar Dexamethasone compared to mock treated cells. Interleukin-7 receptor alpha (IL-7Rα) is essential for T cell survival and differentiation. Glucocorticoids are potent enhancers of IL-7Rα expression with diverse roles in T cell biology. Here we identify the transcriptional repressor, Growth factor independent-1 (Gfi1), as a novel intermediary in glucocorticoid-induced IL-7Rα upregulation. We found Gfi1 to be a major inhibitory target of dexamethasone by microarray expression profiling of 3B4.15 T-hybridoma cells. Concordantly, retroviral transduction of Gfi1 significantly blunted IL-7Rα upregulation by dexamethasone. To further assess the role of Gfi1 in vivo, we generated bacterial artificial chromosome (BAC) transgenic mice, in which a modified Il7r locus expresses GFP to report Il7r gene transcription. By introducing this BAC reporter transgene into either Gfi1-deficient or Gfi1-transgenic mice, we document in vivo that IL-7Rα transcription is upregulated in the absence of Gfi1 and downregulated when Gfi1 is overexpressed. Strikingly, the in vivo regulatory role of Gfi1 was specific for CD8+, and not CD4+ T cells or immature thymocytes. These results identify Gfi1 as a specific transcriptional repressor of the Il7r gene in CD8 T lymphocytes in vivo. A six chip study using total RNA recovered from three separate flasks of mock treated 3B4.15 cells and three separate flasks of Dexamethasone treated 3B4.15 cells . Each chip measures the expression level of 44170 target genes

Characterizing the interactions between a naturally-primed IgA (mAb 260.8) and its conserved Bacteroides thetaiotaomicron species-specific epitope in gnotobiotic mice [array]

Project description:Comparisons of gnotobiotic Rag1-/- mice, with and without subcutaneous 260.8 hybridomas, disclosed that this IgA does not affect B. thetaiotaomicron population density or suppress 260.8 epitope production but does affect bacterial gene expression in ways that are emblematic of a diminished host innate immune response. C57BL/6 wildtype, C57BL/6J Rag1-/- , and C57BL/6J Rag1-/- mice harboring the 260.8 IgA producing hybridoma were colonized for 10 days with Bacteroides thetaiotaomicron VPI-5482.

Sequencing the anti-MUC1 hybridoma antibody 139H2

Project description:Mucin 1 (MUC1) is a transmembrane mucin expressed at the apical surface of epithelial cells at different mucosal surfaces including breast and intestine. The MUC1 extracellular domain contains a variable number of tandem repeats (VNTR) of 20 amino acids, which are heavily O-linked glycosylated. Monoclonal antibodies against the MUC1 VNTR can be powerful tools because of their multiplicity of binding and possible applications in the diagnosis and treatment of MUC1-expressing cancers. One such antibody is the hybridoma mouse monoclonal 139H2 which is also widely used as a research tool to study non-cancer MUC1. Here we report direct mass spectrometry-based sequencing of hybridoma-derived 139H2 IgG, which enabled reverse engineering of a recombinant 139H2.

Lck promotes Zap70-dependent LAT phosphorylation by bridging Zap70 to LAT

Project description:T cell antigen receptor (TCR) signaling depends upon the kinases Lck and Zap70. Lck phosphorylates the TCR, facilitating Zap70 recruitment to the stimulated TCR. Lck also phosphorylates Zap70, relieving its auto-inhibition and activating its catalytic domain. Zap70 then phosphorylates the critical adaptors LAT and SLP76 which serve to nucleate key effector molecules required for downstream responses. However, mechanisms facilitating the interaction of Zap70 with its substrates have not been described. We report an evolutionarily conserved proline-rich motif in LAT is important for Zap70-induced phosphorylation of LAT and downstream signaling. This LAT proline-rich motif associated with the Lck SH3 domain, thereby facilitating Zap70-mediated phosphorylation of LAT and downstream functions. Our results suggest Lck orchestrates multiple steps in TCR signaling including the newly described facilitation of the interaction of Zap70 with its substrate LAT. This previously unrecognized feature of TCR proximal signaling may contribute to the development of more immunomodulatory therapies.

Quantitative proteomics analysis of signalosome dynamics in primary T cells identifies the surface receptor CD6 as a Lat adaptor-independent TCR signaling hub

Project description:The aim of the dataset was to study on a genome-wide level the impact of Lat deficiency on gene expression in resting and activated CD4+ T cells Lat+ and Lat? CD4+ T cells were isolated from lymph nodes and spleen of Latfl-dtr Tmat-Cre mice using a Dynabeads untouched mouse CD4 cells kit (Life Technology) and further purified by cell sorting. Lat+ CD4+ T cells were defined as: CD5+, hDTR+, CD8?, TCR???, CD25?, CD69?, CD62L+, lineage (CD11c, CD11b, CD19, CD45R, CD161)? and Lat? CD4+ Tcells were defined as: CD5+, hDTR?, CD8?, TCR???, CD25?, CD69?, CD62L+, lineage (CD11c, CD11b, CD19, CD45R, CD161)?. Sorted Lat+ or Lat? CD4+ T cells were then kept in vitro for 4 hours without stimulation or activated for 4 hours using anti-CD3 antibody and anti-CD28 antibody. Cell samples corresponding to three biological replicates were analyzed and gene expression profiles were obtained from total RNA.
