The cellular prion protein (PrPc) is a membrane glycoprotein expressed on many human cells including platelets. We investigated the cellular localization of platelet PrPc. In resting platelets most PrPc was localized inside the cells. The correlation of PrPc and P-selectin surface up-regulation after platelet activation suggested its association with alpha-granules. This was confirmed by normal...
Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disease that displays genetic heterogeneity; there are 9 known subtypes. HPS is characterized by oculocutaneous albinism, a platelet storage pool deficiency and resultant bleeding diathesis, and lysosomal accumulation of ceroid lipofuscin. Patients with HPS, specifically those with the genotypes HPS-1, HPS-2, or HPS-4, are predispose...
Two human diseases of platelet storage pool deficiency (SPD). Hermansky-Pudlak syndrome and Chediak-Higashi syndrome. are recessively inherited disorders characterized by hypopigmentation. prolonged bleeding. and normal platelet counts accompanied by a reduction in dense granule number. We have recently described seven independent recessive mutations in the mouse regulated by separate genes whi...
Methods: Spectral-domain OCT imaging was performed on study subjects in 3 groups: subjects with ocular albinism (OA) or suspected OA with foveal hypoplasia, with nystagmus, and with or without iris transillumination; a subject with oculocutaneous albinism and Hermansky-Pudlak syndrome; and control subjects. Dense volumetric scans of each fovea were captured using standard and handheld spectral-...
