CC chemokine receptor 5 (CCR5; CD195)

Cell culture and mouse studies suggest inhibiting CCR5 could help treat Staphylococcus aureus infections. In vitro, S. aureus leukotoxin killed CCR5-expressing cell lines. The effect was blocked with multiple small molecule CCR5 antagonists. In a model of S. aureus systemic infection, Ccr5 knockout mice had lower bacterial load and greater survival than wild-type mice. Next steps include developing animal models that can monitor the efficacy of CCR5 antagonists.
Pfizer Inc. markets the CCR5 antagonist Selzentry maraviroc to treat HIV/AIDS.
