Abstract

Whole-blood-cell cultures from schistosomiasis patients were stimulated with a variety of T-cell-dependent and T-cell-independent stimuli to determine whether the defect in type 1 cytokine expression observed following helminth infection is associated with alterations in interleukin-12 (IL-12) or CD40 ligand (CD40L) responsiveness. Cultures from uninfected individuals produced abundant gamma interferon in response to Staphylococcus aureus Cowan 1 (SAC), while patients with intestinal and hepatosplenic disease displayed intermediate and weak responses, respectively. Importantly, the decrease in type 1 cytokine expression was not attributed to defects in IL-12- or CD40L-induced activity. Indee..
