In an endeavor to further characterize human intercellular adhesion molecule-2 (ICAM-2), two murine monoclonal antibodies (mAb) were generated to ICAM-2 transfected COS cells, and designated CBR-IC2/1 and CBR-IC2/2. Immunoprecipitated, reduced ICAM-2 migrated as a broad band of Mr 60,000 in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Treatment with N-glycanase revealed a peptide ...

We have studied the cytokine regulation of cell surface and soluble intercellular adhesion molecule 1 (ICAM-1) expression on the human melanoma cell line A375M. Unstimulated cells express ICAM-1 on their cell surface but do not secrete significant levels of soluble ICAM-1. Interleukin 1, interleukin 6, tumor necrosis factor, and gamma-interferon all increased cell surface expression of ICAM-1. ...

Although ICAM-3 is implicated in both adhesion and signal transduction events of leukocytes, its low affinity for LFA-1 compared to other ligands of LFA-1 has puzzled many investigators. Here we investigated the role of ICAM-3 in supporting LFA-1-mediated ICAM-1 binding and subsequently cell signaling. We observed that although ICAM-3 binds poorly to LFA-1 expressed on resting T cells, it speci...

BACKGROUND Therapy-induced inflammation and progressive fibrosis limit the efficacy of thoracic radiotherapy for lung neoplasms. However, mice bearing a null mutation of intercellular adhesion molecule 1 (ICAM-1) have previously been found to display no inflammatory cell infiltration into the lung following thoracic irradiation. We investigated the role of ICAM-1-mediated inflammation in the pa...

Immunological explanatory approaches are becoming increasingly important in schizophrenia research. In this context, the function of blood-brain barrier (BBB) and blood-cerebrospinal fluid (CSF) (BCSFB) plays an essential role. Different adhesion molecules, such as intercellular molecule-1 (ICAM-1) vascular cell (VCAM-1), key elements sustaining integrity BBB BCSFB. The objectives study were to...
