Localization and regulation of thrombopoietin

Avatrombopag is an investigational oral thrombopoietin
, a hormone that regulates production of platelets, has been found to peak shortly after birth and gradually decline to adult concentrations (26), which could explain the higher platelet counts observed in early childhood.
An example is the protein tyrosine kinase JAK2, which transduces signals from ligand-bound cell surface receptors for thrombopoietin
(TPOR/MPL) and erythropoietin (EPOR).
and the TPO receptor during platelet storage.
There are several second-line therapies: spelenectomy, rituximab, danazol, azathioprine, and thrombopoietin
agonists such as eltrombopag and romiplostim.

However other drugs may be used in future if the thrombopoietin
(TPO) mimetic proves safe and effective in various paediatrics trials currently in progress.
concentrations are low in patients with cirrhosis and thrombocytopenia and are restored after orthotopic liver transplantation.
7 The cause is multifactorial due in part to increased sequestration in the spleen bone marrow suppression by HCV infection and by interferon treatment and reduced production of thrombopoietin
(a cytokine that regulates megakaryocyte maturation and platelet production).
Bone marrow megakaryocytes may be normal or increased during infection, but platelet destruction is increased, with significantly elevated thrombopoietin
levels in patients with severe infection (3-5).
