GtoPdb Ligand ID: 5063

Comment: This is the endogenous ligand of the thrombopoietin receptor. It promotes proliferation of megakaryocytic cells, which leads to increased platelet production. Human TPO is not used therapeutically as it is associated with a risk of immunogenicity and the development of neutralizing anti-TPO antibodies [1-2]. As a result of this outcome small molecule TPO receptor agonists have been developed to mimic the platelet-promoting action of native TPO.
