Short Term, Low Dose Simvastatin Pretreatment Alters Memory Immune Function Following Secondary Staphylococcus aureus Infection.

Statins are potent modulators of immune responses, resulting in their ability to enhance host survival from primary bacterial infections. Alterations in primary immune responses that may be beneficial for survival following infection may also result in alterations in the generation of the immunologic memory response and subsequently affect immune responses mounted during secondary bacterial infection. In this study, we report that levels of total serum IgG2c, following primary infection, were decreased in simvastatin pretreated mice, and investigate the effect of simvastatin treatment, prior to primary infection, on immune responses activated during secondary S.
