P2RY12 and Venous thrombosis: We have indeed shown this, by proving that the antibodies used for P2Y12, recognizing either the C-terminus or the second intracellular loop of the receptor (Figure 1 and Table 1) and immunolabelling, respectively, microglia or myelinated fibers in the CNS, are all still able to immunoreact for instance with platelets (Figure 5), where the receptor was originally described to be present and to have a role in the processes of activation, aggregation [46–49], primary hemostasis, and arterial thrombosis [50–55].
