The process is highly regulated by cell adhesion molecules, particularly, the addressin also known as MADCAM1. This antigen is known for its role in tissue-specific adhesion of lymphocytes to high endothelium venules. [23] Through these interactions they play a crucial role in orchestrating circulating lymphocytes.
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
The molecules responsible for creating cell junctions include various cell adhesion molecules. There are four main types: selectins, cadherins, integrins, and the immunoglobulin superfamily. [15] Selectins are cell adhesion molecules that play an important role in the initiation of inflammatory processes. [16]
Vascular cell adhesion protein 1 also known as vascular cell adhesion molecule 1 (VCAM-1) or cluster of differentiation 106 (CD106) is a protein that in humans is encoded by the VCAM1 gene. [5] VCAM-1 functions as a cell adhesion molecule .
The loss of the cell adhesion molecules, E cadherins, is causally involved in the formation of epithelial types of cancers such as carcinomas. The changes in any types of cadherin expression may not only control tumor cell adhesion but also may affect signal transduction leading to the cancer cells growing uncontrollably. [23]
The immunoglobulin superfamily (IgSF) is a large protein superfamily of cell surface and soluble proteins that are involved in the recognition, binding, or adhesion processes of cells. Molecules are categorized as members of this superfamily based on shared structural features with immunoglobulins (also known as antibodies); they all possess a ...
Integrins work alongside other proteins such as cadherins, the immunoglobulin superfamily cell adhesion molecules, selectins and syndecans, to mediate cell–cell and cell–matrix interaction. Ligands for integrins include fibronectin , vitronectin , collagen and laminin .
In molecular biology, intercellular adhesion molecules (ICAMs) and vascular cell adhesion molecule-1 (VCAM-1) are part of the immunoglobulin superfamily. They are important in inflammation, immune responses and in intracellular signalling events. [1] The ICAM family consists of five members, designated ICAM-1 to ICAM-5.
