Project description:Whipple's disease (WD) affects only a very small minority of individuals infected by Tropheryma whipplei (Tw). Asymptomatic and chronic carriage of the causative organism is less rare and therefore, the pathogenesis of WD is poorly understood. Here we studied transcriptome responses in peripheral blood mononuclear cells (PBMCs) that were obtained from members of a large multiplex French kindred including otherwise healthy WD patients, healthy chronic carriers of Tw and other unrealted control subjects.
Project description:We have employed whole genome microarray expression profiling to identify differently expressed genes following infection of bone-marrow derived macrophages with T. whipplei. Macrophages were infected with T. whipplei (MOI 50:1) for 6 hours and a signature was identified that distinguished between infected and control samples. Expression of several genes from this signature was quantified in the same RNA samples by real-time PCR, confirming the predicted macrophage response pattern.

Expression of several genes from this signature was quantified in the same RNA samples by real-time PCR, confirming the predicted macrophage response pattern. Gene expression in macrophages was measured at 6 hours after infection. Three independent experiments were performed.
Project description:We have employed whole genome microarray expression profiling to identify differently expressed genes following infection of interleukin-16-knock-out bone-marrow derived macrophages with T. whipplei. Macrophages were infected with T. whipplei (MOI 50:1) for 6 hours and a signature was identified that distinguished between infected and control samples. Expression of several genes from this signature was quantified in the same RNA samples by real-time PCR, confirming the predicted macrophage response pattern.

Project description:Bone marrow-derived macrophages from mice were treated with recombinant Ssa1, a protein enriched in the hypoxic secretome of Candida albicans.
