Project description:An unresolved issue in immunology is the extent to which inflammatory effects are needed for robust T cell responses. In this study, mice were immunized by iv injection using either high toxicity lipopolysaccharide (LPS) or low toxicity monophosphoryl lipid A (MPL) as adjuvant. Six hours after iv immunization, whole spleens were harvested and gene expression was measured in unfractionated splenic populations of cells. The analysis indicated that the low toxicity adjuvanticity of MPL was associated with TLR4-mediated signaling that was biased to the TRIF branch of TLR4, while LPS generated balanced MyD88 and TRIF-associated outcomes. Experiment Overall Design: B6.SJL mice adoptively transferred with T cells from B6.OTI and OTII transgenic TCR transgenic were immunized via intravenous injection with ova peptides alone ("Ova"), or with LPS ("OvaLPS") or MPL as adjuvant ("OvaMPL"). Six hours after immunization, the mice were euthanized by cervical dislocation, the spleens were removed and immediately lysed in guanidium chloride, and kept frozen until being used to extract total cellular RNA. Three mice each were given the indicated treatments, with independent processing and analysis of nine samples total.

Project description:The purpose if this experiment was to determine how a 24 hour treatment with dmLT, MPL-A, and the combination thereof induced gene expression in dendritic cells when compared to LPS and ATP treatment. The knowledge gained from this study would allow us to identify mechanistic pathways that are unique to each adjuvant, which would allow us to further explore their function in DCs.

Project description:Many vaccination studies have revealed various degrees of protection in mouse models. However, the mechanism of protection is not fully understood. The aim of this study was to identify genes specifically expressed in H. pylori infection and prophylactic immunized mice. A prophylactic immunization with purified protein of H. pylori BabA combining with the mucosal CTA1-DD adjuvant was performed in a-1,3/4-fucosyltransferase transgenic FVB/N mice. Gene expression profile was analysed from the gastric mucosa among untreated, the infected and immunized mice. There were a set of genes were upregulated or downregulated respectively, in infected mice as compared with untreated mice. These include the adipokines released form adipose tissue, adhesion molecules and actin cytoskeletal rearragemet associated genes. In immunized mice, however, the host response was not as strong as in infected mice and significantly changed genes were completely overlapped with those in infected mice. The expression data from genechip was confirmed by quantitative real-time PCR assay. The microarray analysis suggests that genes such as actin cytoskeletal molecules and adipokines may be as potential targets of H. pylori infection. Prophylactic immunization with purified protein of H. pylori BabA combining with the mucosal CTA1-DD adjuvant could reduce bacteria colonization without induced a severe degree of inflammation. Keywords: response to treatment The gastric antrum form three groups of mice were prepared for Affymetrix gene chip analysis, using samples from the infected group, untreated control group (not immunized and not challenged) and the immunized group (challenged J99 four weeks after immunization). Four mice in each group were analysis by microarray.

Project description:Differential gene expression profile of Tfh and non-Tfh cells from both Wt and miR-155-/- mice spleens. Wt and miR-155-/- mice were immunized with OVA. 8 days post immunization, CD4+CXCR+PD1+ Tfh cells and CD4+CXCR5-PD1- non Tfh cells were sorted from mice spleens for analyses.

Project description:To explore TNF-related genes in GPI-induced arthritis, we performed GeneChip analysis using arthritic splenocytes and control-immunized splenocytes. Among the arrayed TNFalpha-related genes, TIARP mRNA was highly expressed in arthritic splenocytes, with levels exceeding more than 20-times the control splenocytes The spleens of three GPI-GST (MW=89 kD) (300 µg) -immunized DBA/1 mice were harvested on day 10. As a control, the spleens of three GST (MW=26 kd) (100 µg) -immunized DBA/1 mice were used. Total RNA was extracted from the splenocytes using Isogen (Nippon gene), then 15 ug of RNA was utilized for cDNA synthesis by reverse transcription followed by synthesis of biotinylated cRNA through in vitro transcription. After cRNA fragmentation, hybridization with mouse 430A2.0 GeneChip (Affymetrix, Santa Clara, CA) with probes for 43,000 mouse genes ESTs was performed according to the protocol provided by the manufacturer. Analysis was performed by gene expression software

Project description:Space travel is a growing area of interest and includes initiatives such as NASA's Moon-to-Mars Mission. Studies conducted on the cardiovascular effects of space travel reveal changes in morphology, metabolism, and function. In this study, the cardiovascular response to immunization in space was studied in mice which were housed and immunized while on the International Space Station (ISS). Mice were immunized with tetanus toxoid combined with the adjuvant CpG (TT+CpG) and the effects of vaccination in space were studied using transcriptomics. Analysis of the murine heart transcriptome was performed on ground, flight-control, and flight-immunized mice. Results showed that immunization aboard the ISS stimulates heightened inflammation in the heart via induction of the NF-κB signaling pathway.
