ICAM-1 autoantibodies detected in healthy individuals and cross-react with functional epitopes.

ABSTRACT: Intracellular adhesion molecule 1 (ICAM-1) is a cell surface glycoprotein that regulates cell-cell interactions, signaling, and immune processes. ICAM-1 expression has been shown to be elevated in many types of infections and inflammatory diseases. Strategies to block ICAM-1 function, including monoclonal anti-ICAM-1 antibodies, have been successful in treating the effects of chronic respiratory, autoimmune, and cardiovascular diseases. Naturally occurring autoantibodies targeting cytokines, endothelial cells, and other host receptors have been identified, and have been found to play a role in immunoregulation in health and disease. In this study, we determined the presence and levels of ICAM-1 autoantibodies across different age groups and disease states. We found that ICAM-1 autoantibody
