Fig. 6From: Systemic Listeria monocytogenes infection in aged mice induces long-term neuroinflammation: the role of miR-155Lm ΔactA infection of aged mice triggers sustained leukocytosis in the brain. Male C57BL/6JN mice aged 19 mo were infected with 2.1 × 107 CFU Lm ΔactA (n = 5, ●, ▲), or injected with PBS as uninfected controls (n = 6, ○, Δ). All mice received amoxicillin in their drinking water. One infected mouse died at 2d p.i. Mice were sacrificed 32d p.i., and brain leukocytes were analyzed by FACS. Symbols represent individual mice. Line indicates mean. Statistical significance calculated via Student’s t testBack to article page
