CD163 and infection: In the same way, when the levels of expression of FN1 were measured, the three bacteria analyzed in this study induced an expression statistically significantly higher in comparison to the non-infected condition (p < 0.0001 for all serotypes) at both times of infection, and differences among the serotypes were only observed at 2 h of infection for serotype c on serotype a (p = 0.0103) (Figure 3D), just as happened with CD163.
