Antibodies against complement-regulatory proteins on platelets in immune thrombocytopenia.

abstract：:Dopamine (DA), a catecholamine neurotransmitter, is known to for its diverse roles on hematopoiesis, yet its function in thrombopoiesis remains poorly understood. This study shows that DA stimulation can directly induce platelet production from megakaryocytes (MKs) in the final stages of thrombopoiesis via a reactive ...

abstract：:It has recently been demonstrated that both initiators and inhibitors (viz iloprost) of aggregation stimulate the uptake of [(45)Ca(2+)] by human platelets. Since it was postulated that this calcium uptake reflects changes associated with signal transduction, we investigated the role of cAMP-dependent protein kinases ...
