A novel murine model of fetal and neonatal alloimmune thrombocytopenia: response to intravenous IgG therapy.

Fetal and neonatal alloimmune thrombo cytopenia (FNAITP) is a life-threatening bleeding disorder caused by maternal antibodies directed against fetal platelet antigens. The immunoreactive epitopes in FNAITP are primarily located in the extracellular regions of the platelet glycoprotein IIIa (beta3 integrin). Here we have established a novel animal model of FNAITP using beta3 integrin-deficient ...

Neonatal alloimmune thrombocytopenia: current considerations.

Some mothers produce antibodies to the platelet antigens of their fetuses. Exposure to these antigens may occur owing to prior transfusions or through feto-maternal hemorrhage during gestation or delivery. The sensitizing antigen is usually an epitope of one of the glycoproteins (GP) found on the platelet membrane. Specific GPs act as receptors for factors important in hemostasis, such as von W...

Fetal and neonatal alloimmune thrombocytopenia.

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is one of the major causes of both severe thrombocytopenia and intracranial haemorrhage in fetuses and term neonates. The incidence of FNAIT is estimated to be one in 1000-2000 births. FNAIT is caused by maternal immunoglobulin G alloantibodies, which cross the placenta and are directed against human platelet antigens (HPA) on fetal platele...
