Inflammatory marker expression in mouse brain and liver. Brain and liver obtained from infected CCR5−/− mice and C57BL/6 mice (wild-type, WT) at 5 days post-infection were prepared for measurement of their mRNA levels. The mRNA levels in brain (A) and liver (B) were standardized against the β-actin and GAPDH mRNA level values, respectively. The values per individual (symbols) and mean levels (horizontal lines) are indicated. Data were obtained from two independent experiments performed together. The individual with undetectable expression are not indicated. Data were analyzed by a student’s t-test. *P < 0.05.
