In vitro production of interleukin (IL)-12 (pg/ml + s.e.m.) by peripheral blood mononuclear cells from healthy donors (n = 6). Spontaneous IL-12 release (medium) or in response to different concentrations of Echinococcus multilocularis metacestode culture supernatant (EmMed 2–40%) as well as increasing numbers of viable vesicles (EmVes 1–8) are shown.
