Project description:To identify subsets of antigen presenting cells in the normal healthy mouse lung based on gene expression profiling, lung tissues including airways were enzymatically dissociated, and CD11c+ cells were magnetically enriched and submitted for single cell analysis using the 10x genomics pipeline.
Project description:We applied Illumina massively parallel signature sequencing to identify miRNomes in CD11c+Ia high and CD11c+Ia low cells.The miRNomes of these DC subsets will contribute to investigate the significance of miRNAs in DC immunobiology. Examination of miRNome in CD11c+Ia high and CD11c+Ia low cells . All two mouse cell types.
Project description:Abatacept is a recombinant CTLA-4 moleculed fused to a mutated human IgG molecule, which is clinically used in rheumatoid arthritis by inhibiting CD28-costimulation. This study aimed to inverstigate the ability of abatacept -mediated costimulation blockade to induce antigen-specific tolerance during primary immune responses. This is important as some studies have suggested that costimulation blockade can lead to CD4+ T cell anergy which could be beneficial for early therapy of autoimmune diseases such as rheumatoid arthritis. In addition we also investigated the effect that abatacept has on CD11c+ antigen presenting cells. This is important as costimulation blocakde can affect the biderectional interaction between CD4+ T cells and CD11c+ cells influencing the immunological outcome. We used microarrays to identify if abatacept treatment leads to antigen specific anergy using transgenic animals and models of priming and oral tolerance that established a synchronised monoclonal response. In addition this magnified the effect on the CD11c+ antigen presenting cells.
Project description:Microarray analysis of IECs from Tlr5+/+ and Tlr5-/- mice stimulated with either medium alone or flagellin (1 µg/ml); to elucidate TLR5-mediated immune responses in CD11c+ LPCs Keywords: ordered
Project description:We aimed to characterize CD11c+ B cells from healthy humans by gene expression analysis. We report that CD11c+ B cells are a distinct subpopulation of B cells, even if their phenotype is heterogeneous, with overexpression of genes involved in B cell activation and antigen presentation.
Project description:Transcriptome analysis of dentritic cells from the spleen (CD11c+) or MLN (CD11c+CD103+) of mice with DC-specific deletion of TGFBR2 gene, or their control littermates. TRGFR2 gene was deleted in dendritic cells using Cre/lox approach. Mice with this deletion develop spontaneous multi-organ autoimmune inflammation and die by 15 weeks of age. Splenic CD11c+ Dc were isolated by magetic cell sorting. MLN CD11c+CD103+ DC were flow sorted. RNA was isolated using RNAqueous-Micro kit (Ambion) and analyzed using Affymetrix Mouse Exon 1.0 ST Array
Project description:Embelin (15 uM) induced alterations in the gene expression profile was studied in A549 lung cancer cells during the initial stages of apoptosis (4h following treatment)

We used microarrays to identify if abatacept treatment leads to antigen specific anergy using transgenic animals and models of priming and oral tolerance that established a synchronised monoclonal response. In addition this magnified the effect on the CD11c+ antigen presenting cells. This study included 5 experimental groups. DO11.10 RAG2-/- mice have CD4+ T cells specific for the ovalbumin (OVA) peptide OVA323-339. These mice were immunised with CFA/OVA s.c. (primed group) or tolerised by feeding with OVA (50mg/kg) in the drinking water. CD4+ cells were isolated 10 days post immunisation from draining lymph nodes (LNs) of unimmunised (pooled LNs and Spleen), orally tolerised (mesenteric LNs), primed (axillary LNs), primed treated with control IgG (axillary LNs) and primed treated with abatacept (axillary LNs). For CD11c+ cells cells were isolated by pooled secondary lymphoid organs (LNs and spleen).
