Due to an advanced prostatic carcinoma 166 patients were given a massive dose of oestrogen over a period of 10 days (6 g Honvan i.v.). A retrospective comparison of a control group of 94 patients without prophylaxis against thrombosis and a control group of 36 patients having received Heparin-Dihydergot did not show a significant difference of cardiovascular complications. Therefore, further 36 patients received a thrombocyte aggregation inhibitor (Godamed) as prophylaxis against embolic thrombosis. At the same time lung perfusion scintigraphy (99m Tc-Microspheres) was made directly before and after oestrogen therapy. Clinically and lung scintigraphically there was no different thromboembolic incidence compared to the patients given a Heparin-Dihydergot prophylaxis.

Recent studies have shown that anti-ERp5 antibodies inhibit platelet activation and thrombus formation; Moreover, ERp5-deficient platelets exhibit enhanced platelet reactivity via regulation of endoplasmic reticulum (ER) stress. In this study, we used a new ERp5-knockout mouse model as well as recombinant ERp5 (rERp5) protein, to examine the role of ERp5 in platelet function and thrombosis. Although platelet-specific ERp5-deficient mice had decreased platelet count, the mice had shortened tail-bleeding times and enhanced platelet accumulation in FeCl-induced mesenteric artery injury, compared with wild-type mice.

Ticagrelor has become the standard drug for the treatment of intracranial aneurysms (IAs) with flow diverters (FDs), but the dosage has not been standardized. The effect of platelet function on clinical and imaging prognosis remains unclear. This study aimed to show the effects of different doses of ticagrelor and platelet aggregation function on the clinical and imaging prognosis after FDs treatment of aneurysms.

In thrombosis and hemostasis, the formation of a platelet-fibrin thrombus or clot is a highly controlled process that varies, depending on the pathological context. Major signaling pathways in platelets are well established. However, studies with genetically modified mice have identified the contribution of hundreds of additional platelet-expressed proteins in arterial thrombus formation and bleeding.

Platelet cells are essential to maintain haemostasis and play a critical role in thrombosis. They swiftly respond to vascular injury by adhering to damaged vessel surfaces, activating signalling pathways, and aggregating with each other to control bleeding. This dynamic process of platelet activation is intricately coordinated, spanning from membrane receptor maturation to intracellular interactions to whole-cell responses.
