PATHOLOGY

Detailed explanation-1: -Peyer’s patches (PP) are visible lymphatic structures that were first discovered in the human small intestine (Cornes, 1965). Due to the capability of PP to manage antigens and bacteria in the luminal areas, they are considered as the immunosensors in the intestine.

Detailed explanation-2: -Peyer’s patches are groupings of lymphoid follicles in the mucus membrane that lines your small intestine. Lymphoid follicles are small organs in your lymphatic system that are similar to lymph nodes.

Detailed explanation-3: -The gut-associated lymphoid tissues (GALT) comprise a collection of multifollicular structures, including the tonsils, Peyer’s patches, appendix, colonic and cecal patches, and a number of smaller, single follicular structures termed isolated lymphoid follicles (ILF).
