Fig. 4From: Mycobacterium avium infection induces the resistance of the interferon-γ response in mouse spleen cells at late stages of infectionReal-time PCR analysis. Bone marrow and spleen cells were isolated from mice at 24 h and 2, 4, and 12 weeks after infection and mRNA of Sca-1 and IFN-γ (a) and IRF-1 and IRF-2 (b) were analyzed. Data represent two independent experiments each performed in triplicate. Each value is presented as mean ± standard deviation. Significant differences (*P < 0.05) were determined using Student’s t testBack to article page
