چکیده

Based on protein sequence, we have isolated a cDNA for intercellular adhesion molecule 3 (ICAM-3), the most recently defined counter-receptor for lymphocyte function-associated antigen 1 (LFA-1). Expression of the cDNA yields a product that reacts with monoclonal antibody to ICAM-3 and functions as a ligand for LFA-1. The deduced 518-amino acid sequence of the predicted mature protein defines a highly glycosylated type I integral membrane protein with five immunoglobulin (Ig)-like domains. The five Ig-like domains of ICAM-3 are highly homologous with those of human ICAM-1 (52% identity) and human ICAM-2 (37% identity).

Localization of the binding site on intercellular adhesion molecule-3 (ICAM-3) for lymphocyte function-associated antigen 1 (LFA-1).

Intercellular adhesion molecule 3 (ICAM-3; CD50) is the predominant counter-receptor on resting T cells and monocytes for the leukocyte integrin, lymphocyte function-associated antigen 1 (LFA-1; CD11a/CD18), and may play an important role in the initial stages of the T cell-dependent immune response. Deletion of individual immunoglobulin superfamily (IgSF) domains of ICAM-3 and ICAM-3 IgSF doma...

Intercellular adhesion molecule 3, a third adhesion counter-receptor for lymphocyte function-associated molecule 1 on resting lymphocytes

Recent studies suggest that some T and B lymphocyte cell lines bind to the integrin lymphocyte function-associated molecule 1 (LFA-1) chiefly through a pathway independent of its two known counter-receptors, intercellular adhesion molecules (ICAMs)-1 and -2. A monoclonal antibody (mAb) was raised that, in combination with blocking mAb to ICAM-1 and ICAM-2, can completely inhibit binding of thes...

Characterization of the function of intercellular adhesion molecule (ICAM)-3 and comparison with ICAM-1 and ICAM-2 in immune responses

We have characterized the immunobiology of the interaction of intercellular adhesion molecule 3 (ICAM-3; CD50) with its counter-receptor, leukocyte function-associated antigen 1 (LFA-1; CD11a/CD18). Purified ICAM-3 supported LFA-1-dependent adhesion in a temperature- and cation-dependent manner. Activation of cells bearing LFA-1 increased adhesiveness for ICAM-3 in parallel to adhesiveness for ...

Endothelial adhesion molecules and leukocyte integrins in preeclamptic patients.

Endothelial cell activation is important in the pathogenesis of preeclampsia; however, the nature of the activation is unknown. We investigated 22 patients with preeclampsia. 29 normotensive pregnancies, and 18 nonpregnant women to test the hypothesis that serum from preeclamptic patients induces expression of intercellular adhesion molecule-1 (ICAM-1) and vascular adhesion molecule-1 (VCAM-1) ...
