However, we did not detect any differences in IL22 levels between infected WT and CCR6−/− mice at 24 h after infection (infected wild type mice vs. infected CCR6−/− mice: 4.08±1.51 pg/mg brain protein vs. 3.39±1.84 pg/mg brain protein, p = 0.37) or at 48 h after infection (infected wild type mice vs. infected CCR6−/− mice: 3.15±1.78 pg/mg brain protein vs. 2.59±0.59 pg/mg brain protein, p = 0.74). The gene discussed is CCR6; the disease is infection.
