CNS-4 is required for human IFN-γ production. A, Transgenic CD4+ cells were cultured under Th1 and Th2 polarizing conditions for three days. Human IFN-γ (left) or mouse IFN-γ (right) concentrations were determined from cultures. B, Day five CD4+ Th1 cultures were restimulated with anti-CD3, or IL-12 and IL-18, or IL-12 and IL-2. Human and mouse IFN-γ concentrations were determined by ELISA. Results are representative of independent replicates. Error bars are standard deviations. * P < 0.05.
