    Abstract:
    To study the cellular basis for specific antigen-induced leukocyte adherence inhibition, enriched populations of B cells, T cells, and monocytes were prepared by a two-stage adherence separation procedure from spleen cells of normal C57BL/6J mice and mice bearing progressively growing MCA-38 tumors. The reactor cell undergoing specific antigen-induced adherence inhibition was identified as a monocyte (esterase positive, did not respond to mitogens, and did not bear Thy 1.2 antigen or surface immunoglobulin). Furthermore, an enriched population of MCA-38 sensitized B cells could program normal monocytes to undergo specific antigen-induced adherence inhibition. This programming could be abolished by pretreatment of the MCA-38 sensitized B cells with anti-immunoglobulin and complement (indirect cytotoxicity method). In contrast, enriched populations of MCA-38 sensitized T cells could not program normal nylon wool adherent cells to undergo antigen-specific adherence inhibition; and anti-Thy 1.2 serum and complement had no effect on specific antigen-induced adherence inhibition. Thus, in this murine tumor model, leukocyte adherence inhibition appears to be due to the programming of monocytes by sensitized B cells.
