Mucosal vascular addressin cell adhesion molecule 1 (MAdCAM-1) is a protein that in humans is encoded by the MADCAM1 gene.[3][4][5] The protein encoded by this gene is an endothelial cell adhesion molecule that interacts preferentially with the leukocyte beta7 integrin LPAM-1 (alpha4 / beta7), L-selectin, and VLA-4 (alpha4 / beta1) on myeloid cells to direct leukocytes into mucosal and inflamed tissues. It is a member of the immunoglobulin superfamily and is similar to ICAM-1 and VCAM-1.[3]

Nomenclature
Addressin is a lesser-used term to describe the group of adhesion molecules that are involved with lymphocyte homing, commonly found at high-endothelial venules (HEVs) where lymphocytes exit the blood and enter the lymph node.[6][7] Addressins are the ligands to the homing receptors of lymphocytes.[8] The task of these ligands and their receptors is to determine which tissue the lymphocyte will enter next. They carry carbohydrates in order to be recognized by L-selectin.[9] Addressins physically bind to mobile lymphocytes to guide them to the HEVs.[6] Examples of molecules that are often referred to as addressins are CD34 and GlyCAM-1 on HEVs in peripheral lymph nodes, and MAdCAM-1 on endothelial cells in the intestine.[7]
Function
In terms of migration, MAdCAM-1 is selectively expressed on mucosal endothelial cells, driving memory T-cell re-circulation through mucosal tissues. In contrast, and indeed the main difference between the two molecules, ICAM molecules are involved with naïve T-cell re-circulation. Whereas MAdCAM-1 is selectively expressed, ICAM is broadly expressed on inflamed endothelium.
Peripheral node addressins
Peripheral node addressins (PNAd) are carbohydrate residues that are lymphocyte homing receptor ligands that are expressed on the HEVs of peripheral lymph nodes.[10] These proteins collectively bind to L-selectin to guide lymphocytes such as mature naïve B and T cells into the lymph node.[9][11][12] During the development of secondary lymphoid organs, PNAd expression is upregulated following the upregulation and subsequent downregulation of MAdCAM-1 on HEVs.[12] PNAd expression, as well as the expression of MAdCAM-1, is dependent on lymphotoxin signaling in the HEVs of lymph nodes.[12]
Clinical significance
In inflammatory bowel diseases, MAdCAM-1 can be overexpressed on the endothelial cells of intestinal mucosa and gut‐associated lymphoid tissue, leading to excessive inflammation in the gut.[13] A potential therapeutic target to manage these diseases could be the MAdCAM-1 molecules that are expressed on these cells and bring in lymphocytes. One example of a potential therapy is the fully human monoclonal antibody ontamalimab that targets and binds to MAdCAM-1, preventing it from interacting with the integrins on the surface of the lymphocytes.[14]
