Project description:To distinguish between Helicobacter pylori isolates that may cause greater disease in patients, we used whole genome expression profiling as a platform to study host-pathogen interactions and identify gene signatures associated with isolates from patients with higher cancer risk.
Project description:Helicobacter pylori causes chronic gastritis and avoids elimination by the immune system of the infected host. The commensal bacterium Lactobacillus acidophilus has been reported to exert beneficial effects as a supplement during H. pylori eradication therapy. In the present study, we applied whole genome microarray analysis to compare the immune response induced in murine bone marrow derived macrophages (BMDM) stimulated with L. acidophilus, H. pylori, or with both bacteria in combination
