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 ...
L1-Cell Adhesion Molecule (L1CAM) was first discovered to be important in neuron-related tissue development in the mid-1980s, and is a trans-membranal glycoprotein of approximately 200-220 kDa. On its extracellular domain, the L1CAM protein includes IgG -like and fibronectin -III (FN-III) repeats which allow for interaction with integrins and ...
They include soluble isoforms of the cell adhesion molecules ICAM-1, VCAM-1, E-selectin and P-selectin (distinguished as sICAM-1, sVCAM-1, sE-selectin and sP-selectin). The cellular expression of CAMs is difficult to assess clinically, but these soluble forms are present in the circulation and may serve as markers for CAMs.
L1, also known as L1CAM, is a transmembrane protein member of the L1 protein family, encoded by the L1CAM gene. This protein, of 200 to 220 kDa, is a neuronal cell adhesion molecule with a strong implication in cell migration, adhesion, neurite outgrowth, myelination and neuronal differentiation. [5]
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 ...
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.
JAM-1 was the first of the junctional adhesion molecules to be discovered, and is located in the tight junctions of both epithelial and endothelial cells. [8] JAM-1interacts with cells in a homophilic manner in order to preserve the structure of the junction while moderating its permeability.
