FcRγ promotes thrombosis in response to oxLDL. WT and FcRγ^−/− mice were injected with oxLDL (2.5 mg per kg body weight) or phosphate-buffered saline vehicle, followed by FeCl₃ (5%) injury and in vivo thrombosis assessed by intravital microscopy. (A) Representative fluorescence images of thrombi formed under different conditions are shown over the course of 30 minutes after vascular injury. Black arrow shows the direction of blood flow. (B) Representative median integrated fluorescence signals of rhodamine G obtained from an individual carotid thrombus under different conditions. (C) Quantification of median integrated fluorescence signals of peak thrombus size at 10, 20, and 30 minutes after vascular injury taken from WT and FcRγ^−/− mice (n = 5) for each treatment. ∗P < .05.
