title: Adherence of peripheral blood leukocytes to cytomegalovirus-infected fibroblasts.
abstract: Peripheral blood monocytes and B cells adhered to cytomegalovirus (CMV)-infected fibroblasts, whereas T cells and polymorphonuclear leukocytes did not adhere to either CMV-infected or uninfected fibroblasts. When T cells were activated with anti-CD3 antibody, activated T cells demonstrated adherence and cytotoxicity to both CMV-infected and uninfected fibroblasts. Adherence of peripheral blood mononuclear cells (PBMC) and cytotoxicity mediated by adherent activated T cells were blocked by treatment of CMV-infected fibroblasts with anti-ICAM-1 antibody and by treatment of leukocytes with anti-LFA-1 antibody. These data suggest that an interaction of ICAM-1 and LFA-1 is responsible for the adherence of leukocytes and for adherent activated T cell-mediated cytotoxicity against CMV-infected fibroblasts.
