Lamina propria intestine

The lamina propria is one of three layers which make up the mucosa, or mucous membrane. The lamina propria is a large layer of connective tissue which separates the innermost layer of epithelial cells from a layer of smooth muscle tissue called the muscularis mucosa. This can be seen in the image below, of a small intestine. The lamina propria. Foci of lamina propria inflammation, edema, aphthous ulcers, and focal crypt injury produce an irregular distribution of crypts in the lamina propria.Variation in crypt size can also be seen if crypt injury has resulted in patchy crypt architectural disarray, a feature most easily appreciated at medium or low magnification (Fig. 14-21)

♦ Lamina propria of any organ opening to the exterior of the body. May occur singly (solitary) or in clusters (aggregates) such as in tonsils and Peyer's patches in the small intestine. Lymphoid nodules in the lamina propria are part of MALT. ♦ Lymph node and spleen ♦ Primary nodule -small fingerlike projections on the plicae circulares of the small intestine that increase surface area -cores are formed from folds of lamina propria -smooth muscle cells from the muscularis mucosae are scattered in the lamina propria -villi are covered by enterocyte

Mucosa, submucosa, muscularis propria (externa), subserosa, serosa Mucosa: Contains villi with central blood vessels, lymphatics Layers are epithelium, lamina propria, muscularis mucosa Villi: Short and stubby in duodenum, very tall in jejunum, intermediate height in ileum Contain microvilli Villus to crypt length is 3 - 5: The lamina propria contains capillaries and a central lacteal (lymph vessel) in the small intestine, as well as lymphoid tissue. Lamina propria also contains glands with the ducts opening on to the mucosal epithelium, that secrete mucus and serous secretions. The lamina propria is also rich in immune cells known as lymphocytes Some small intestinal lamina propria DCs express CX 3 CR1, and CX 3 CR1 + DCs may serve as a gateway for the uptake of microbiota by the continuous sampling of luminal content via transepithelial. The addition of lamina propria macrophages to intestinal DC-T cell cocultures (at a ratio of 1:1 with DCs) abrogated T H-17 differentiation but did not alter the differentiation of IFN-γ.

Observations by us and others indicate that such interactions occur in the intestinal mucosa; distinct dendritic cell (DC) subsets of the small intestinal lamina propria (LP) constitutively endocytose self-antigens derived from apoptotic intestinal epithelial cells and transport them to the T-cell areas of mesenteric lymph nodes (MLNs), where. The characterization of classical DCs (cDCs) in the intestinal lamina propria has been under intense investigation in recent years but the use of markers (including CD11c, CD11b, MHC class II), which are also expressed by intestinal MΦs, has led to some controversy regarding their definition

The small intestine and large intestine together form a continuous long tube that stretches from the stomach to the anus. Their purpose is to process and absorb nutrients and water from the food that we eat. The small intestine is about 20 feet long and 1 inch in diameter.
