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 domes and sparsely populated interfollicular areas. Whereas the dome epithelium of proximal PPs consisted of alkaline phosphates positive enterocytes and scattered M cells with low alkaline phosphatase activity, ileal dome epithelia predominantly consisted of M cells and few enterocytes. The domes of PPs contained numerous IgG plasma cells and a few or moderate number of IgA plasma cells.
