  • Title: In vitro effect of statins on cytokine production and mitogen response of human peripheral blood mononuclear cells.
    Author: Bessler H, Salman H, Bergman M, Straussberg R, Djaldetti M.
    Journal: Clin Immunol; 2005 Oct; 117(1):73-7. PubMed ID: 16051523.
    Abstract:
    The in vitro effect of the hydrophilic statin - pravastatin - and three hydrophobic statins - atorvastatin, lovastatin and simvastatin - on the production of IL-1beta, IL-1ra, IL-2, IL-6 and IFN-gamma by human peripheral blood mononuclear cells (PBMC) and their response to mitogens was examined. Lovastatin and simvastatin increased the production of IL-1beta in a dose dependent manner and reduced secretion of IL-1ra at high concentration. These two statins exerted a dose dependent inhibitory effect on IL-2 production and reduced the secretion of IFNgamma at high dose. Atorvastatin did not affect IL-1beta, but suppressed IL-1ra, IL-2 and IFNgamma production. Atorvastatin, lovastatin and simvastatin caused a dose dependent inhibition of mitogen-induced proliferation of PBMC. IL-6 production was not affected by any one of the statins. While pravastatin caused a slight reduction in the proliferative response of PBMC to PHA, it did not affect either their response to Con A and PWM, or the secretion of cytokines tested.
