Antibody binding reports spatial heterogeneities in cell membrane organization [PDF]
, 2022 The spatial organization of cell membrane glycoproteins and glycolipids is critical for mediating the binding of ligands, receptors, and macromolecules on the plasma membrane. However, we currently do not have the methods to quantify the spatial heterogeneities of macromolecular crowding on live cell surfaces.

Platelet membrane glycoproteins: historical perspectives [PDF]
Journal of Thrombosis and Haemostasis, 2006 3–9. The function of blood platelets to prevent blood loss at injured sites in the vasculature depends largely on their capacity to adhere, aggregate, promote coagulation and secrete factors that induce vasoconstriction and recruit inflammatory cells. Produced in large numbers from megakaryocytes, platelets enter the circulation for 7–10 days primed to

Pathogenic mechanisms contributing to thrombocytopenia in patients with systemic lupus erythematosus
Platelets, 2022 Systemic lupus erythematosus (SLE) is an autoimmune condition developing thrombocytopenia in about 10–15% of cases, however, mechanisms leading to low platelet count were not deeply investigated in this illness.

Frequency of human platelet antigens −1 to −5 and −15 in Turkmen blood donors
Advanced Biomedical Research, 2023 Background: Due to the presence of platelet antigen polymorphisms, human platelet membrane glycoproteins can be identified as an alloantigen or autoantigen.

von Willebrand Factor unfolding mediates platelet deposition in a model of high-shear thrombosis [PDF]
, 2022 Thrombosis under high-shear conditions is mediated by the mechanosensitive blood glycoprotein von Willebrand Factor (vWF). vWF unfolds in response to strong flow gradients and facilitates rapid recruitment of platelets in flowing blood. While the thrombogenic effect of vWF is well recognized, its conformational response in complex flows has largely ...

The trans-sialidase from Trypanosoma cruzi induces thrombocytopenia during acute Chagas' disease by reducing the platelet sialic acid contents [PDF]
, 2005 Strong thrombocytopenia is observed during acute infection with Trypanosoma cruzi, the parasitic protozoan agent of American trypanosomiasis or Chagas' disease.

Convergent evolution of pregnancy-specific glycoproteins in human and horse [PDF]
, 2016 Pregnancy-specific glycoproteins (PSGs) are members of the carcinoembryonic antigen cell adhesion molecule (CEACAM) family that are secreted by trophoblast cells. PSGs may modulate immune, angiogenic and platelet responses during pregnancy.

Platelet-Induced Clumping of Plasmodium falciparum–Infected Erythrocytes from Malawian Patients with Cerebral Malaria—Possible Modulation In Vivo by Thrombocytopenia [PDF]
, 2008 Platelets may play a role in the pathogenesis of human cerebral malaria (CM), and they have been shown to induce clumping of Plasmodium falciparum–parasitized red blood cells (PRBCs) in vitro.
