FOXP3 and infection: Main effects of sex and infection, as well as a sex by infection interaction, were noted for the expression of FOXP3 [F(1,30) = 5.69, p = 0.024, F(1,30) = 13.69, p < 0.001, and F(1,30) = 5.01, p = 0.033, respectively; Figure 5H], with T. gondii-infected females having significantly increased FOXP3 expression compared to males (p = 0.003) and compared to vehicle females (p < 0.001).
