Protein targeting to dense‐core secretory granules
BioEssays, 1993AbstractRegulated secretory proteins are stored within specialized vesicles known as secretory granules. It is not known how proteins are sorted into these organelles. Regulated proteins may possess targeting signals which interact with specific sorting receptors in the lumen of the trans‐Golgi network (TGN) prior to their aggregation to form the ...

Dense Granule Antigens of Toxoplasma Gondii
1993In the search for protective antigens aiming at the development of a sub-unit vaccine against toxoplasmosis, several molecules have been found to represent good candidates, in particular P30 or SAG1, the major surface antigen of tachyzoite [Burg et al., 1988; Bulow and Boothroyd, 1991].

Dense granules (lysosomes?) and crystals in the thyroids of senile rats
American Journal of Anatomy, 1968AbstractWhile all follicular cells display some dense “lysosome‐like” granules (0.1–2.5 μ), they are more numerous and complex in animals of 14 months or older. There are various types of granules which share some morphological features, but vary in the extent to which they accumulate dense membranous fragments and droplets (0.02–0.4 μ) within their ...

Ultrastructural Cytochemistry of Intranuclear Dense Granules in Nasopharyngeal Angiofibroma
Ultrastructural Pathology, 1984Electron-dense round granules (ING) were found in the nuclei of fibroblastic cells of all the tumors examined by us (6 cases) and diagnosed clinically and histologically as nasopharyngeal angiofibroma (NPAF). The ING were consistently associated with this tumor and can be regarded as pathognomonic of NPAF.

Histamine uptake in pig platelets and isolated dense granules
Biochemical Pharmacology, 1984Histamine, a major constituent of the amine-storage organelles in pig platelets, is taken up by intact platelets in only trace amounts under conditions where 70% of 14C-serotonin is accumulated. Thrombin caused the release of 70-90% of endogenous histamine but only 5-10% of the newly absorbed 3H-amine; however, after 18 hr 30% of the 3H-amine could be ...

The light side of platelet dense granules
Blood, 2004Comment on Gwynn et al, page [3181][1] An article in this issue of Blood provides genetic and molecular insights into a critical but relatively little understood aspect of platelet physiology, that is, the biosynthesis of platelet dense granules.

A cytochemical study of dense granules in the rat junctional epithelium
Journal of Periodontal Research, 1989To clarify the details of inlracyloplasmic granules in the junctional epithelium (JEI of the rat gingwo, phosphotungstlc acid (PTA) staining. acid phosphatase cytochemistry and zmc iodide‐osmium (ZIO) staining were carried out. Con‐densing granules containing homogeneous electron‐dense materials. measuring ahout 260 nm in diameter.
