Statins Decrease Toll-Like Receptor 4 Expression and Downstream Signaling in Human CD14 + Monocytes
Open accessAbstract
Objective— Anti-inflammatory effects of statins contribute to their clinical benefit. Molecular mechanisms underlying these effects have not been well explored. Because statins attenuate lipopolysaccharide (LPS) responsiveness, we hypothesized that part of the pleiotropic effects are mediated through innate immunity. Methods and Results— Toll-like receptor (TLR) 4 expression and downstream signaling in CD14 + monocytes after incubation with simvastatin and atorvastatin were quantified via flow-cytometry, quantitative RT-PCR, kinase assay, and enzyme-linked immunosorbent assay. Incubation with intermediates/ inhibitors of the mevalonate pathway was used to identify the mode of statin action. Statin incubation resulted in a dose-dependent reduction of TLR4 expression (53±7.6% reduction compared with untreated monocytes; P <0.005), transcript levels (68±6.3%; P <0.002), decreased IRAK phosphorylation (37±8.3%; P <0.05), and LPS-induced IL-6, IL-12, tumor necrosis factor (TNF)-α, and B7-1 expression ( P <0.05). Four weeks of treatment with atorvastatin significantly reduced TLR4 expression on circulating CD14 + monocytes by 36.2±4.2% ( P <0.05). Effects of statins were reversed by mevalonate ( P =0.57). Incubation with specific inhibitors of geranylgeranyltransferase (54±4.3%), farnesyltransferase (57±5.1%), or with clostridium-difficile toxin B (58±6.1%, P <0.01) imitated the statin effects. Whereas wortmannin and LY294002 inhibited the statin effect ( P =0.27), incubation with a specific RhoA kinase inhibitor had no effect ( P =0.57). Conclusions— Statins influence TLR4 expression and signaling via inhibition of protein geranylgeranylation and farnesylation. These observations imply interactions with innate immunity as one pleiotropic mechanism.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
