High endothelial venules (HEV) are specialized post-capillary venules characterized by plump endothelial cells as opposed to the usual flatter endothelial cells found in regular venules. HEVs enable lymphocytes circulating in the blood to directly enter a lymph node (by crossing through the HEV). In humans, HEVs are … Ver mais In order to have an adaptive immune response occur, T cells need to be activated. T cells become activated by recognising foreign antigens bound to antigen presenting cells (APC), in particular, Ver mais The vessels with HEV characteristics appear in human tissue in association with long-standing chronic inflammation. In rheumatoid arthritis, it has been observed that the level of sulfate incorporation as well as the 'plumpness' (or 'tallness') of the endothelium in … Ver mais HEV cuboidal endothelial cells express the adhesion molecules GlyCAM-1 (in mucosal HEV this is MAdCAM-1), ICAM-1 and CD34.
