Purinergic Modulation of Granule Cells
The Cerebellum, 2010Extracellular purines exert their action in the nervous system through purinergic neurotransmission and neuromodulatory processes. Among brain areas, efforts have been made to investigate the purinergic modulation of the cerebellar cortex. In addition, the use of granule cells in culture as a neuronal in vitro model provided important information about

Isolation of Mast Cell Granules
Current Protocols in Cell Biology, 2005AbstractThe mast cell is a multipotent inflammatory cell that has been shown to participate in the pathogenesis of a variety of diseases, such as immediate hypersensitivity reactions, arthritis, atherosclerosis, and heart failure. Upon stimulation, mast cells exocytose cytoplasmic secretory granules into their extracellular microenvironment.

Tachykinins and excitotoxicity in cerebellar granule cells
The Cerebellum, 2006The tachykinins represent an important group of neuropeptides that are widely distributed both in the central and peripheral nervous system where they perform several functions connected with neuronal modulation, often in synergy with glutamate excitatory transmission.

Intradermally injected peroxidase was found in the Langerhans' cell granules of the epidermal Langerhans' cells. As time elapsed, the number of stained granules increased, reaching the maximum at 22 hours, and tended to concentrate near the Golgi zone.

Cytoplasmic Granules in Fibrogenic Cells
Nature, 1955A SYSTEMATIC investigation into the method of elaboration of intercellular material in connective and skeletal tissues has shown that cytoplasmic granules, which contain polysaccharide protein components, are present in fibrogenic cells of the fowl embryo both in vivo and in vitro.

Cytoplasmic granules in myogenic cells
Experimental Cell Research, 1955respiration of these amoebae is strongly inhibited by cyanide [4, 10, 111 indicating the presence of a terminal cytochrome oxidase. From our own studies on Tetrahymena geleii (GL) and from the work of Eichel [5] it appears that these organisms also operate on a cytochrome e system. In washed, packed Tetrahymena geleii, observed spectroscopically in the

Birbeck Granules (Langerhans’ Cell Granules) in Human Lymph Nodes
American Journal of Clinical Pathology, 1973Electron microscopic examination of lymph nodes from “normal” subjects and diseased patients revealed the presence of Birbeck granules in histiocytes in 8 of 12 patients with subacute sclerosing panencephalitis (SSPE), 1 of 6 patients with other diseases, and 1 of 4 “normal” subjects. The one apparently “normal” subject who had Birbeck granules was the

Granule secretion by the luteal cell of the sheep: The fate of the granule membrane
Cell and Tissue Research, 1979The ultrastructure of the corpus luteum of the sheep has been examined at the mid-stage of the estrous cycle when progesterone secretion is active. Secretory granules are associated with the secretion of this hormone, and the evidence indicates that the granule membrane becomes incorporated into the plasma membrane during exocytosis.

Cell Culture of Primary Cerebellar Granule Cells
2010Cerebellar granule cells are often used as a model system for the study of neuronal development, function and pathology, including the analysis of activity-dependent survival/apoptosis of neurons and the mechanisms of neuroprotection. Cerebellar granule cells are generated postnatally and constitute the largest homogeneous neuronal population of the ...

Effect of Age on Mast Cell Granules
International Archives of Allergy and Immunology, 1981<i>Padawer</i> has proposed that rat mast cells in the peritoneal cavity have an extended lifespan and under normal conditions exhibit little turnover of their secretory granules. We have examined several constituents of the granules as part of a study of the structure and function of these organelles.
