Abstract excerpt
We previously showed that the MRP4 (ABCC4) transporter is expressed in human platelet delta-granules and may be involved in ADP transport. We now demonstrate by immunoblotting and immunofluorescence microscopy that platelet MRP4 is absent in two patients with a platelet delta-storage pool deficiency (delta-SPD)-like phenotype with reduced platelet adenine nucleotide (AN) but normal serotonin levels, whereas their...
