Cell adhesion molecules in the immune system are believed to play an important role in lymphocyte-target cell conjugate formation. One such molecule, intercellular adhesion molecule 1 (ICAM-1), is important in the function, aggregation, and adherence of leukocytes. Here, we report the isolation and characterization of the murine ICAM-1 gene. We report that the murine ICAM-1 gene is a member of the Ig gene superfamily, has limited homology to its human counterpart, and is expressed in cells of lymphocytic and myeloid lineages. Transfection of the ICAM-1 cDNA into MHC class II-transfected fibroblasts leads to enhancement of the Ag-specific T cell response when the transfectants are used as APC.
