Project description:Our goal is to discriminate specific genes in live M.leprae-infected peritoneal macrophages in comparison to heat-killed M.leprae infected peritoneal macrophages using microarray. Two-condition experiment, Heat-killed M.leprae infected macrophage vs. Live M.leprae infected macrophage. Biological replicates: 16 mice (control), 8 heat-killed M. leprae mice (sample 1), and 8 live M. leprae infected mice (sample 2). Independently grown and harvested from isolator. One replicate per array.
Project description:We profiled cell lines (HCT116, THP1 and Jurkat T) exposed to heat-killed and live Fusobacterium nucleatum using multiple scRNA-seq technologies
Project description:CACO2 cells were exposed to four bacteria ( LGG, BB-12, Bifidobacterium infantis DSM33361(hereafter referred to as DSM33361), and Bifidobacterium breve Bif195 (hereafter called Bif195)), and control (untreated)
Project description:N2 young adult animals were analyzed four hours after exposure to wild-type Candida albicans DAY185, heat-killed C. albicans DAY185 and heat-killed Escherichia coli OP50, all on Brain Heart Infusion (BHI) agar. It was necessary to use heat-killed E. coli OP50 as a control for these experiments because live E. coli OP50 (the normal nematode food source) is pathogenic to nematodes on BHI agar. These data identify the C. elegans genes that are differentially regulated during nematode infection with a human fungal pathogen.

Project description:Bone marrow-derived dendritic cells were infected with live or heat-killed Bordetella and cells were analyzed on day 4 post-infection cells were >90% CD11c-positive
Project description:Members of the serpin (serine protease inhibitor) superfamily have been identified in higher, multicellular eukaryotes, as well as in bacteria, although surveillance of available genome sequences indicates that bacterial serpin-encoding (ser) homologs are not widely distributed. In members of the genus Bifidobacterium this gene appears to be present in at least five, and perhaps up to nine, out of 30 species tested. Moreover, phylogenetic analysis using available bacterial and eukaryotic serpin sequences revealed that bifidobacteria specify serpins that form a separate clade. We characterized the ser210B locus of Bifidobacterium breve 210B, which consists of a number of genes, whose deduced protein products display significant similarity to proteins encoded by corresponding loci found in several other bifidobacteria. Northern hybridization, primer extension, micro array analysis, RT-PCR and Quantitative Real Time (qRT) - PCR analysis revealed that a 3.5 kb polycistronic mRNA, encompassing the ser210B operon with a single transcriptional start site, is strongly induced following treatment of B. breve 210B cultures with particular proteases. In contrast, transcription of the ser homolog of other bifidobacteria, such as Bifidobacterium longum subsp. infantis, Bifidobacterium dentium and B. longum subsp. longum, appears to be triggered by a different set of proteases Transcriptional response to protease treatments (kallikrein, papain and chymotrypsin) of Bifidobacterium breve 210B
