title: Evaluation of lymphocytes' influence in luminol-dependent chemiluminescence emission of mouse spleen cells.
abstract: The focus of this study was to elucidate the influence of lymphocytes on phagocytic cell-dependent chemiluminescence (CL). CL was induced by in vitro addition of mitogens, particulate substances and Keyhole Limpet Hemocyanin (KLH)-antigen. CL was measured in spleen cells of immunologically naive mice and in mice immunized with KLH. Mice immunized with KLH and Freund's adjuvant incomplete (FA) showed a lower CL-response than mice injected with FA only. No influence on CL-activity by lymphocytes derived from immunologically naive mice could be found. Adoptive transfer of T cells from KLH-sensitized donor mice did not influence CL-activity elicited with Zymosan in spleen cells derived from KLH-unsensitized recipient mice. Preincubation of spleen cells with supernatants of T cell cultures or with T cell growth factor (TCGF) stimulated with KLH or Con A could not trigger CL-reactivity. Therefore, the lower CL-response of spleen cells derived from KLH-sensitized mice appears to be not a consequence of a suppressive cellular or lymphokine effect, but is due to direct influence of KLH on accessory cells themselves.
