PKD is for dense granule secretion [PDF]
Platelet secretion of dense granule contents is important for human hemostasis, as is evident from the mucocutaneous bleeding associated with disorders of dense granule biogenesis and secretion.1 Dense granule secretion is also important for growth and stability of platelet thrombi in experimental models of thrombosis.2 Although patients with primary ...

Participation of a transmembrane proton gradient in 5-hydroxytryptamine transport by platelet dense granules and dense-granule ghosts [PDF]
Dense granules, the storage organelles for 5-hydroxytryptamine in blood platelets, have been isolated from porcine platelets and are shown to transport 5-hydroxytryptamine in response to a transmembrane proton gradient (delta pH). Transport in the absence of delta pH is minimal, and it is shown that a rapid increase in transport takes place as delta pH

Absence of platelet phenotype in mice lacking the motor protein myosin Va.
BackgroundThe motor protein myosin Va plays an important role in the trafficking of intracellular vesicles. Mutation of the Myo5a gene causes Griscelli syndrome type 1 in humans and the dilute phenotype in mice, which are both characterised by pigment ...

Characterization of granule-like structures in non-endocrine cells [PDF]
All eukaryotic cells have transport pathways to constitutively secrete proteins. Endocrine, neuroendocrine, and exocrine cells in addition have a regulated secretory pathway that serves the controlled release of hormones, neuropeptides or digestive ...

Platelet Munc13-4 regulates hemostasis, thrombosis and airway inflammation
Platelet degranulation is crucial for hemostasis and may participate in inflammation. Exocytosis in platelets is mediated by SNARE proteins and should be controlled by Munc13 proteins. We found that platelets express Munc13-2 and -4. We assessed platelet

The life cycle of platelet granules [version 1; referees: 2 approved]
Platelet granules are unique among secretory vesicles in both their content and their life cycle. Platelets contain three major granule types—dense granules, α-granules, and lysosomes—although other granule types have been reported.

Evaluation of human platelet granules by structured illumination laser fluorescence microscopy
Many roles of human platelets in health and disease are linked to their ability to transport and secrete a variety of small molecules and proteins carried in dense (δ-) and α-granules.
