The lamina propria may also be rich in vascular networks, lymphatic vessels, elastic fibers, and smooth muscle fascicles from the muscularis mucosae. Afferent and efferent nerve endings can be found in the lamina propria as well. [6] Immune cells as well as lymphoid tissue, including lymphoid nodules and capillaries, may be present.
Olfactory glands, also known as Bowman's glands, are a type of nasal gland situated in the part of the olfactory mucosa beneath the olfactory epithelium, that is the lamina propria, a connective tissue also containing fibroblasts, blood vessels and bundles of fine axons from the olfactory neurons.
Some diseases result from a poorly functioning basement membrane. The cause can be genetic defects, injuries by the body's own immune system, or other mechanisms. [12] Diseases involving basement membranes at multiple locations include: Genetic defects in the collagen fibers of the basement membrane, including Alport syndrome and Knobloch syndrome
Blood vessels play a huge role in virtually every medical condition. Cancer, for example, cannot progress unless the tumor causes angiogenesis (formation of new blood vessels) to supply the malignant cells' metabolic demand. [32] Atherosclerosis represents around 85% of all deaths from cardiovascular diseases due to the buildup of plaque. [33]
It exhibits interlacing, [4] loosely organized fibers, [citation needed] abundant blood vessels, and significant empty space filled with interstitial fluid. Many adjacent epithelial tissues (which are avascular) get their nutrients from the interstitial fluid of areolar tissue; the lamina propria is areolar in many body locations. Its fibers ...
the mAb MECA-367 recognizes mucosal addressin cell adhesion molecule 1 (MAdCAM-1), a counter-receptor for L-selectin and α4β7 integrin that is expressed in mucosal HEVs and in venules of intestinal lamina propria but can be induced in nonmucosal endothelial cells by tumor necrosis factor cx (TNF- α) and IL-l. [4]
The vesicles pass from the basal margin into the surrounding lamina propria for interaction with nearby nerve synapses, lymph and blood vessels. The serotonin synthesised by EC cells is predominately exocytosed from the basal border, but is also known to be apically secreted into the lumen of the gut and can be present in faecal samples.
