Plaques. In mechanism, we explored the effect of TMAO on the macrophage polarization and efferocytosis in RAW264.7 cells. Our results demonstrated that TMAO treatment substantially inhibited the M2 polarization and efferocytosis of RAW264.7 cells in vitro, with no apparent effect on the M1 polarization. These final results recommended that TMAO triggered the instability of carotid atherosclerotic plaque could possibly via impeding macrophage M2 polarization and efferocytosis.2021 The Author(s).

MMI administration inhibited efferocytosis in vivoImmunofluorescence staining was used to evaluate the expression of cleaved caspase-3 in carotid arteries samples of mice in water-5-week, MMI-5-week and 5-LOX Inhibitor supplier LCA-5-week groups.ConclusionThe present study demonstrates that MMI-induced TMAO reduction enhances the stability of carotid atherosclerotic plaques, which may be induced by the promotion of macrophage M2 polarization and efferocytosis. Collectively, this study demonstrates that MMI may be applied as an effective drug to improve the stability of carotid atherosclerotic plaques.

This difficulty might be partially attributed to the challenges of attaining great specificity more than quite a few closely related enzymes that happen to be implicate.
