Evidence that platelet-derived microvesicles may transfer platelet-specific immunoreactive antigens to the surface of endothelial cells and CD34+ hematopoietic stem/ progenitor cells--implication for the pathogenesis of immune thrombocytopenias.

Abstract excerpt

The pathogenesis and tissue damage that accompanies destruction of platelets in immune thrombocytopenias (IT) is still not understood very well and in addition to platelets, other cells (e.g. endothelial cells, CD34+ hematopoietic stem/progenitors) may also become affected. Based on our previous work that platelet antigens (e.g., CD41) may be transferred by platelet-derived microvesicles (PMV) to the surface of...
