Infection-associated inflammation can alter the expression levels and functions of cytochrome P450s (CYPs). Cyp gene expression is regulated by the activation of several nuclear receptors, including pregnane X receptor (PXR), constitutive androstane receptor (CAR), and aryl hydrocarbon receptor (AhR).
