“…Gunmetal platelets have an unusual alteration in migration pattern upon sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) of low molecular weight guanosine triphosphate (GTP)-binding proteins, implicated in the regulation of the biosynthesis and intracellular movement of organelles (Schimmoller et al, 1998;Chavrier & Goud, 1999). A related combined alpha and dense granule abnormality has been described in alpha/delta storage pool deficiency syndrome (Weiss et al, 1979). Alpha granule deficiencies, similar to those of the gunmetal mouse, occur in the rare grey platelet syndrome (Smith et al, 1997), and similar combined hypopigmentation and dense granule abnormalities occur in Hermansky-Pudlak syndrome (HPS) (Shotelersuk & Gahl, 1998;Swank et al, 1998;Spritz, 1999).…”

“…This thromboplastic activity was ascribed to the presence of numerous membranous blebs, vesicles and lamellar structures and bodies as seen in TEM (197). Similarly looking material originating from activated platelets in the form of multivesicular structures was discussed (1 10-1 14,116,135,136,181). It probably should be pointed out, that platelet multivesicular structures or bodies bear striking morphological resemblance also to multivesicular bodies isolated from fibroblasts (73) and share blebs appearance similar to secondary lysosomes of certain endothelia during their exocytosis (123).…”

“…As is the case in lysosomes, platelet storage organelles accumulate mepacrine and acridine orangelysosomotropic drugs with a great affinity to an acidic interior of lysosomes, where they can be detected easily by their fluorescence (126,(224)(225)(226)(227). A claim that mepacrine accumulates only in platelet dense bodies (227) is contradicted by the fact, that many granules in a given platelet stain with mepacrine (126,(224)(225)(226)(227), whereas frequency of dense bodies in human platelets seems to be less then 1 per platelet (14,15). Recently Costa et al (228) suggested that 60% of quinacrine resides in dense granules and 14% in platelet lysosomes, but their morphometry technique includes alphagranules under the term of dense granules and is thus in agreement with important observation on mepacrine accumulation in platelet alphagranules (224).…”

“…Hermansky-Pudlak syndrome is characterized by oculocutaneous albinism, a mild bleeding diathesis caused by a storage pool platelet defect, and widespread deposition of ceroid pigment in cells of the reticuloendothelial system. 2294,2295 Complications include pulmonary fibrosis, renal failure, cardiomyopathy and a granulomatous colitis. 2294 The disease is autosomal recessive and genetically heterogeneous, 2296,2297 resulting from defects in genes affecting the function of multiple cytoplasmic organelles.…”
