Factor XI antigen and activity in human platelets [PDF]

open access: yesBlood, 1982
Abstract Washed platelets, contaminated with less than 0.20% plasma factor XI, were examined for the presence of factor XI antigen and activity. These platelets contained a factor-XI-like coagulant activity (0.67 +/- 0.11 U/10(11) platelets) that remained constant after successive washes.

Evidence that platelet-derived microvesicles may transfer platelet-specific immunoreactive antigens to the surface of endothelial cells and CD34+ hematopoietic stem/ progenitor cells--implication for the pathogenesis of immune thrombocytopenias.

open access: yesFolia Histochemica et Cytobiologica, 2007
The pathogenesis and tissue damage that accompanies destruction of platelets in immune thrombocytopenias (IT) is still not understood very well and in addition to platelets, other cells (e.g.

Association of human platelet antigen polymorphisms with platelet count and mean platelet volume [PDF]

open access: yesHematology, 2018
Although recent genome-wide association studies have identified a number of single nucleotide polymorphisms associated with platelet count and mean platelet volume (MPV), it is unclear whether polymorphisms in the human platelet antigens (HPA) genes are associated with platelet count and MPV.

Neonatal Alloimmune Thrombocytopenia Detected After Traumatic Delivery: Case Report

open access: yesForbes Tıp Dergisi, 2021
Neonatal Alloimmune Thrombocytopenia (NAIT), a complication of maternal alloimmunization against fetal platelets, is the result of immune destruction of platelets due to maternal antibodies in the early period.

Foetal and neonatal alloimune thrombocytopenia as a rare exapmle of thrombocytopenia in newborn

open access: yesJournal of Education, Health and Sport, 2018
Foetal and neonatal alloimmune thrombocytopenia (FNAIT) is caused by antigenic incompatibility of platelets between a pregnant woman and her child, resulting in producing antibodies by a mother against specific antigens (HPA- Human Platelet Antigens ...

Platelet antibodies identification: comparison between two laboratory tests

open access: yesHematology, Transfusion and Cell Therapy, 2022
Introduction: Platelet antibody identification is indispensable for diagnosing the human platelet antigen (HPA) or human leukocyte antigen (HLA) immunization, mostly because it can restrict the compatibility and results of transfusions. Correct detection

Unappreciated HLA Antibodies in Adult Immune Thrombocytopenic Purpura

open access: yesJournal of the Formosan Medical Association, 2007
Immune thrombocytopenic purpura (ITP) is an autoimmune disease. Platelet refractoriness is frequently seen in patients with ITP. Platelets express platelet-specific antigens and human leukocyte antigens (HLA).

Human platelet antigen-3 polymorphism as a risk factor for rheumatological manifestations in hepatitis C

open access: yesRevista da Sociedade Brasileira de Medicina Tropical, 2020
INTRODUCTION: Hepatitis C virus (HCV) infection is involved in the pathogenesis of autoimmune and rheumatic disorders. Although the human platelet antigens (HPA) polymorphism are associated with HCV persistence, they have not been investigated in ...

Immunocytochemical Studies on Platelets. The Demonstration of a Common Antigen in Human Platelets and Megakaryocytes [PDF]

open access: yesBlood, 1960
Abstract By means of the fluorescent antibody technic of Coons and Kaplan it was possible to demonstrate a common antigenic structure in human platelets and megakaryocytes, both in nonthrombocytopenic cases and in cases with idiopathic thrombocytopenic purpura.
