Popis: | The expression of lymphokine genes during infection of virulent (Tulahuén) or mild (CA-I) strains of T. cruzi was studied in mice lacking CD4 and/or CD8 molecules. The increased susceptibility of CD4- and CD4-CD8- mice to infection with CA-I or Tulahuén was parallelled by diminished IFN-gamma mRNA levels. Nitric oxide release and inducible nitric oxide synthase mRNA accumulation by cells from Tulahuén infected CD4- mice was also diminished. CD8- (but not CD4-CD8- mice) showed an increased IL-4 and IL-10 mRNA accumulation upon infection with both strains of T. cruzi. A 'Th2-like' response (higher IL-4 and IL-10 mRNA to IFN-gamma mRNA ratio), was also observed when cells from noninfected CD8- mice were stimulated with T cell mitogens. |
