Benzo(a)pyrene attenuates the pattern-recognition-receptor induced proinflammatory phenotype of murine macrophages by inducing IL-10 expression in an aryl hydrocarbon receptor-dependent manner.

Abstract excerpt

Polycyclic aromatic hydrocarbons such as benzo(a)pyrene (BaP) are environmental contaminants known to be immunosuppressive. Most effects of BaP towards immune cells are thought to be mediated through activation of the aryl hydrocarbon receptor (AhR). The AhR is a ligand-activated transcription factor, which plays a critical modulatory role in various cells during immune response. Macrophages are key players in...
