Abstract
Previous reports from this laboratory have demonstrated that human CD4+ Toxoplasma-specific cytotoxic T cell (CTL) clones generated by stimulation of peripheral blood mononuclear cells with Toxoplasma RH strain antigens also recognized target cells expressing C strain antigens. To extend these observations, additional Toxoplasma isolates were studied. A simple system for assessment of cytotoxicity using T cell lines rather than cloned CTL was used. Stimulation of human peripheral blood mononuclear cells with Toxoplasma RH strain antigens elicited cytotoxic T cell lines specific for target cells expressing antigens derived from many other Toxoplasma strains. Cell lines produced by stimulation with antigens derived from the related, nonpathogenic coccidian Besnoitia jellesoni were also cytotoxic for target cells expressing Toxoplasma antigens. Proliferative responses to many Toxoplasma isolates and to the Toxoplasma p30 protein were also noted.
