Participation of a transmembrane proton gradient in 5-hydroxytryptamine transport by platelet dense granules and dense-granule ghosts [PDF]

Biochemical Journal, 1981
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

Occurrence of "Nuages" and "Lamellae Anulata" during spermatogenesis in Dermatobia hominis (Diptera: Cuterebridae)

Memorias do Instituto Oswaldo Cruz, 1995
Various types of "nuages" and "lamellae anulata" can be found during Dermatobia hominis spermatogenesis. In spermatogonia, the "nuages" occur as granules juxtaposed to the cytoplasmic face of the nuclear envelope or as cytoplasmic granules similar to ...

EGFP-FMRP Granules Are Proto-Granules That Can Be Shunted to Stress Granules During a Stress Response [PDF]

, 2010
Overexpressed EGFP-FMRP has been used as a substitute for endogenous fragile X mental retardation protein (FMRP) in protein-protein interaction studies, and in studies concerning the composition, the formation and the localization of neuronal granules ...

Bacterial selection during the formation of early-stage aerobic granules in wastewater treatment systems operated under wash-out dynamics

Frontiers in Microbiology, 2012
Aerobic granular sludge is attractive for high-rate biological wastewater treatment. Biomass wash-out conditions stimulate the formation of aerobic granules.

Molecular Aspects of Secretory Granule Exocytosis by Neurons and Endocrine Cells [PDF]

, 1994
Neuronal communication and endocrine signaling are fundamental for integrating the function of tissues and cells in the body. Hormones released by endocrine cells are transported to the target cells through the circulation.

Rab3D is critical for secretory granule maturation in PC12 cells. [PDF]

, 2013
Neuropeptide- and hormone-containing secretory granules (SGs) are synthesized at the trans-Golgi network (TGN) as immature secretory granules (ISGs) and complete their maturation in the F-actin-rich cell cortex.

Rab11A regulates dense granule transport and secretion during Toxoplasma gondii invasion of host cells and parasite replication.

PLoS Pathogens, 2020
Toxoplasma gondii possesses an armada of secreted virulent factors that enable parasite invasion and survival into host cells. These factors are contained in specific secretory organelles, the rhoptries, micronemes and dense granules that release their ...
