The morphology and function of Peyer's patches in the dog
Canine Peyer's patches (PPs) were characterized by immunohistology, alkaline phosphatase histochemistry and electron microscopy. Duodenal PPs were very similar to jejunal PPs, except for the consistent presence of intrafollicular invaginations of the dome epithelium. The single ileal PP had small …

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 …

Spatial transcriptomic analysis of low-grade intestinal T-cell lymphoma and lymphoplasmacytic inflammatory bowel disease in cats
… prospectively collected as controls, to compare Peyer's patches of cats without gastrointestinal or neoplastic diseases with the LGITL and IBD samples. The spatial transcriptomics technique (GeoMx, Nanostring-Bruker) was successfully performed in T and B lymphocytes of cat samples for the first …

Oral uptake and distribution of microspheres
… Fluorescent particles were observed in both the Peyer's patches (PPs), and non lymphoid regions of rat intestinal mucosa after gavage, conductive to the acceptance that more than one mechanism of particle absorption may operate.

The delivery of bioactive proteins using biodegradable microspheres
… particle uptake by antigen presenting cells and Peyer's patches. Systematic immunisation with microspheres with a range of properties showed differences in the time course and extent of the immune response generated, which would allow optimisation of the dosing schedule to provide maximal …

Alternate pathways of cytotoxic T lymphocyte and natural killer cell activation
… of lymphocytes and monocytes to lymph nodes, Peyer's patches, and sites of inflammation. In the present study, we demonstrate that monoclonal antibody (mAb) 9F3, directed against murine CD44 expressed on cytotoxic T lymphocytes (CTls), can trigger the lytic activity of CTls and redirect …

Mucosal Immunopathogenesis of Feline Immunodeficiency Virus (FIV)
… assays. We found the phenotype IEL, LPL and Peyer's patches of cats to be similar to that reported in other species, except for the expression of CD5 and MHC II. Profound loss of IEL and mesenteric lymph node cells was observed in persistent FIV infection. In addition, we detected significant …

Regulation of the germinal center reaction by T helper cells and T regulatory cells
… sheep red blood cells (SRBC) immunization and in Peyer's patches (PPs). In STAT3KO mice, the numbers of splenic GC B cells were markedly decreased, whereas PP GC B cells developed at normal numbers and IgG1 class switching was greatly increased. Unexpectedly, we found that STAT3 intrinsically …

Development of an antigen-specific ELISPOT to detect intestinal antibody responses to the swine whipworm, Trichuris suis
… cecum in large intestine (C-MLN); and ileocecal Peyer's patches (IC-PP)] and lamina propria from the proximal colon removed from T. suis infected pigs. Tbe local antibody responses were compared to peripheral antibody responses found in the spleen and submandibular lymph nodes. The hypotheses to …

Regulation of the beta7 integrin gene in T cells: role of the MAPK signalling pathways
… mediates the homing of lymphocytes to intestinal Peyer's patches, mesenteric lymph nodes, and the lamina propria by binding to the vascular addressin MAdCAM-1 (Fong et al., 1997). αEβ7 binds epithelial E-cadherin retaining lymphocytes at the intraepithelial compartment of the mucosa. The …

Interaction of Salmonella typhimurium and Listeria monocytogenes with the murine host
… associated epithelium (FAE) that overlies Peyer’s patches and other lymphoid follicles, to enter the host. This study is primarily an investigation into the interaction of S. typhimurium and Listeria monocytogenes with the intestinal epithelium, representing the early stage of an infection.
