A Novel Locus of Salmonella Typhimurium Involved in Survival in the Peyer's Patches
… to survival and/or growth of Salmonella in Peyer's patches. Peyer's patches are regions of specialized lymphoid tissue involved in the uptake and processing of luminal antigens. Salmonella are capable of colonizing the Peyer's patch and can survive and multiply within the lymphoid tissue. We …

The Regulation of Salmonella Typhi Vi Capsular Antigen Expression in Intestinal Model Epithelia and the Bovine Ligated-Ileal Loop Model
… within intestinal epithelial cells and bovine Peyer's patch. The second objective was to compare the invasiveness between a viaB mutant, an ompR mutant, and S. Typhi grown under hyperosmolarity. We also measured the effects of these strains in eliciting inflammation in the calf model. We report …

Effects of Acute Alcohol Exposure on Post Burn Intestinal Immunity: Role of IL-23
… and burn injury on intestine associated lymphoid Peyer's patch (PP) Th17 effector functions. We further examined whether in vivo modulation of IL-22 influences gut barrier function and bacterial load following EtOH and burn injury.</p> <p>Our murine model of EtOH intoxication and burn injury …

Coordinate Regulation of Salmonella Virulence Gene Expression During Infection
… of gipA only affects growth or survival in a Peyer's patch. We also determined that a gene located in the B region of Gifsy-1, which we have termed grvB, is an antivirulence gene that is involved in the SodCI-GrvA virulence pathway. GrvB is translocated into the host cytosol in a SPI2 …

Intestinal Handling of Food Grade Titanium Dioxide
… gut and describe the subepithelial dome of the Peyer’s patch as a newly recognised site of accumulation. I then demonstrate the marked similarities between this and fgTiO2 accumulation in human Peyer’s patches through the study of six separate samples from each species. Following this, I sought …

Environmental stimuli shape adaptive immunity by enhancing T helper cell differentiation and the germinal centre response
… the defective germinal centre (GC) reaction in Peyer’s patches in the small intestine of aged mice can be rescued by co-housing of adult and aged mice, and via faecal transfers from adult into aged mice. This demonstrates that the poor GC reaction in aged animals is not irreversible, and that it …
