Clinical indications for thrombopoietin and thrombopoietin-receptor agonists.
Thrombocytopenia is a common hematologic disorder. Stimulation of thrombopoiesis may reduce the risk for thrombocytopenia-induced bleeding, prevent severe thrombocytopenia, and reduce the need for platelet transfusion. The key cytokine is thrombopoietin (TPO). It regulates proliferation and maturation of megakaryocytes as well as platelet production. TPO is synthesized in the liver. Development...
متن کاملThe biology of thrombopoietin and thrombopoietin receptor agonists.
Thrombopoietin (TPO) is the major physiological regulator of platelet production. TPO binds the TPO receptor, activates JAK and STAT pathways, thus stimulating megakaryocyte growth and platelet production. There is no "sensor" of the platelet count; rather TPO is produced in the liver at a constant rate and cleared by TPO receptors on platelets. TPO levels are inversely proportional to the rate...
متن کاملUse of Thrombopoietin Receptor Agonists in Childhood Immune Thrombocytopenia
Most children with immune thrombocytopenia (ITP) will have spontaneous remission regardless of therapy, while about 20% will go on to have chronic ITP. In those children with chronic ITP who need treatment, standard therapies for acute ITP may have adverse effects that complicate their long-term use. Thus, alternative treatment options are needed for children with chronic ITP. Thrombopoietin re...
متن کاملThrombopoietin: Biology and Clinical Applications.
Thrombopoietin (also called c-Mpl ligand, megakaryocyte growth and development factor, megapoietin) has recently been purified and cloned. This molecule is indeed the long-sought-after hematopoietic factor that controls platelet production. Thrombopoietin levels increase within 24 h after the onset of thrombocytopenia and are inversely and exponentially proportional to the platelet count. Injec...
متن کاملThrombopoietin.
By Shirley Ebbe I T HAS BEEN CLEAR for almost 20 years that platelet production is subject to homeostatic regulatory mechanisms that result in stimulation when the platelet count is li w’ and suppression when it is high.2 In spite of elapsed time, the physiologic processes that are involved in those regulatory mechanisms are not clear. Thrombocytopoiesis may be regulated by a humoral thrombopoi...
