Project description:Investigation of the gene expression changes associated with TLR2 adjuvant (lipoteichoic acid; LTA) inhibition of allergic TH2 responses in peripheral blood mononuclear cell cultures (derived from house dust mite allergic individuals) stimulated with house dust mite extract.
Project description:CD4 T cells are essential mediators of the asthmatic process. We used the clinically relevant allergen house dust mites to induce signs of allergy in mice and performed gene expression arrays specifically on CD4 T cells infiltrating the lung Reference: IL-21-producing CD4+ T cells promote type 2 immunity to house dust mites Primary CD4+ T cells were isolated from mice sensitised and challenged to either house dust mites or PBS. Purification of CD4 T cells was performed by flow cytometry. RNA was isolated, converted to cDNA and then hybridised on Affymetrix GeneChip Mouse Gene 2.0 ST Arrays

Project description:Investigation of the gene expression changes associated with TLR2 adjuvant (lipoteichoic acid; LTA) inhibition of allergic TH2 responses in peripheral blood mononuclear cell cultures (derived from house dust mite allergic individuals) stimulated with house dust mite extract. Pooled samples from 5 individuals were analysed by microarray; qPCR validation was carried out in a larger cohort of 23 individuals.
Project description:Response to allergen was studied in bronchial epithelial cell line H292. Cells were cultured and subsequently exposed to House dust mite or vessel (saline); Microarray data was analysed using bioinformatics and biostastics. We find a strong response to allergen in epithelial cells Experiment Overall Design: Bronchial epithelial cell line was cultured and stimulated with house dust mite extract or diluent alone. Both conditions were performed in triplicate
