Abstract

Cytokine responses of peripheral blood mononuclear cells from humans infected with Schistosoma mansoni were assessed. By ELISA and ELISPOT, persons with acute and hepatosplenic infections produced higher levels of interleukin (IL)-4 and IL-5 and higher frequencies of IL-4-producing cells in response to mitogen than did uninfected persons. In contrast, mitogen-induced production of the Th1 cytokine interferon-gamma (IFN-gamma) did not differ from that of uninfected controls. Upon stimulation with egg antigens, many patients responded with elevated IL-4 mRNA levels but displayed no appreciable increases in Th1 (i.e., IFN-gamma and IL-2) cytokine transcripts. Nevertheless, in cells stimulated w..
