- Abstract: Objective: to study how intracellular parasite infections can modulate the development of autoimmune diseases. Methods: IL-10 or iNOS knock out (KO) mice in the C57Bl/6 background and their matching wild type (WT) controls were immunized with 100 mg of MOG 35-55 peptide emulsified vol/vol in CFA enriched with 400 mg of M. bovis. Each mouse received 100 ng of Pertussis toxin intravenously at the same day of immunization and 2 days after, as an additional adjuvant. Groups of mice were also infected with 1000 blood forms of T. cruzi Y strain concomitantly to immunization. After the immunization/infection, the clinical score of EAE was followed and lymph node cells or spleen cells (SC) cultures were performed on days 7th, 14th or 21st to evaluate the proliferative and cytokine responses against the MOG peptide. Results: The infection with T. cruzi completely prevented EAE development and resulted in suppressed of proliferative responses of LNC and SC to MOG 35-55. The blockade of EAE was partially reverted in iNOS or IL-10 KO mice. Interestingly, SC cultures from WT mice immunized and infected produced large amounts of IL-10 after MOG 35-55 stimulation. Conclusion: the results suggest that NO and IL-10 produced during T. cruzi infection may suppress the development of EAE
