Figure 4From: Selenium deficiency impairs host innate immune response and induces susceptibility to Listeria monocytogenes infectionSerum cytokine levels in response to L. monocytogenes infection. Individual serum samples were assayed for levels of IL-12 and IL-10 (A), IL-2 and IL-4 (B). The levels of IL-12 were significantly lower in infected Se-deficient mice in comparison to infected-adequate mice. Results are expressed as the mean concentration per group ± standard deviation (SD). *p < 0.05, **p < 0.01.Back to article page
