Project description:Investigation of whole genome gene expression level changes in Listeria monocytogenes EGD-e during incubation (0, 15 min, 30 min) in two types of soil extracts (TA, DA).
Project description:Comparison of aerobic and anaerobic transcriptome of L. monocytogenes EGD L. monocytogenes EGD cells used in this study were grown either aerobically or anaerobically to an OD600 = 0.70 - 0.75 and the transcriptome of these two conditions was compared Six biologically independent cultures of each aerobically and anaerobically grown L. monocytogenes EGD were used for total RNA isolation (six RNA sets). 4 array experiments were performed with Cy5-labelled cDNA derived from aerobically grown Listeria and Cy3-labelled cDNA derived from anaerobcially grown cells. For the two other RNA sets a dye swap was performed, that means the two other array experiments were performed with Cy3-labelled cDNA derived form aerobically grown Listeria and Cy5-labelled cDNA from anaerobically grown cells. As all oligonuceotides are spotted twice on an array, technical duplicates were performed for each experiment. The overall design results in 12 data points for the expression of each gene.

Project description:The transcriptome of naive OT-I T cells was compared to memory CD8 T cells after 1, 2, 3, or 4 infection with ovalbumin expressing Listeria monocytogenes (LM-OVA). Naive Thy1.1 OT-I T cells were adoptively transferred into Thy1.2 naive hosts prior to infection with LM-OVA. The resulting memory CD8 T cell population was again adoptively transferred into naive hosts and the recipient mice were again infected with LM-OVA. The adoptive transfer was repeated up to four times to generate memory CD8 T cells with up to four consecutive antigen stimulations. Three individual mice were analyzed for each group. For quaternary memory CD8 T cells, spleens from two to three mice were pooled for each sample. Naive OT-I T cells served as control samples. http://dx.doi.org/10.1016/j.immuni.2010.06.014
Project description:We infected wild type L. monocytogenes EGD-e (1) and its isogenic deltahlydeltaplcA (2) (lacking the ability to breach the vacuolar compartment of host cells following uptake) mutant strain to human intestinal epithelial cell line (Caco-2) with an MOI of 100 and 500 respectively. Bacterial total RNA was isolated at 1 h (deltahlydeltaplcA) and 4 h (EGD-e) post infection, reverse transcribed, hybridised to whole genome microarray and microarray data was analysed as described previously (3) 1.
