Evaluation of the electrostatic field strength at the site of exocytosis in adrenal chromaffin cells
ROSENHECK K
Biophys J
. 1998 Sep;
75(3):1237-43.
PMID: 9726926
Exocytosis in secretory cells consists of release from intracellular storage granules directly into the extracellular space via fusion of the granule membrane with the plasma membrane of the cell. It...

Schwaller B, Calef E, Gitler C, ROSENHECK K
Proc Natl Acad Sci U S A
. 1993 Feb;
90(4):1295-9.
PMID: 8433989
To investigate the involvement of cytosolic proteins in exocytosis, a system with high temporal and spatial resolution has been developed that allows us to detect the interaction of Ca(2+)- and...

Castillo C, Fonteriz R, Lopez M, ROSENHECK K, Garcia A
J Neurochem
. 1989 Nov;
53(5):1442-9.
PMID: 2529351
Bovine adrenal medulla plasma membranes were purified by a differential centrifugation procedure using sucrose and Urografin discontinuous density gradients; the membranes were enriched 10-12-fold in acetylcholinesterase activity and [3H]ouabain binding...

Lelkes P, Friedman J, ROSENHECK K, Oplatka A
FEBS Lett
. 1986 Nov;
208(2):357-63.
PMID: 3536577
In the search for a functional role of cytoskeletal proteins in the mechanism(s) of stimulus-secretion coupling, we have previously demonstrated that the actomyosin system might be involved in the transport...

ZAHLER P, Reist M, Pilarska M, ROSENHECK K
Biochim Biophys Acta
. 1986 Jul;
877(3):372-9.
PMID: 3089288
The plasma membranes of bovine adrenal chromaffin cells were isolated and the activities of enzymes involved in arachidonic acid liberation were investigated. Only a minute activity of phospholipase A2 (phosphatide...

Friedman J, Lelkes P, ROSENHECK K, Oplatka A
J Biol Chem
. 1986 May;
261(13):5745-50.
PMID: 2422162
We have incorporated the myosin fragment heavy meromyosin (HMM), which is known to interact mechanochemically and enzymatically with actin filaments, into intact chromaffin cells of the bovine adrenal medulla, in...

ROSENHECK K, Plattner H
Biochim Biophys Acta
. 1986 Apr;
856(2):373-82.
PMID: 3955049
Plasma membrane vesicles obtained by density gradient centrifugation of bovine adrenal medullary homogenates were analyzed by electron microscopic methods, including negative staining, ultrathin sections and freeze-fracture replicas. Rapid freezing showed...

Lelkes P, Friedman J, ROSENHECK K
J Neurosci Methods
. 1985 May;
13(3-4):249-55.
PMID: 4010334
The intrinsic fluorescence of catecholamines can be exploited for a simple and speedy fluorescence assay of secretion from bovine adrenal chromaffin cells. Catecholamines are separated from concomitantly secreted proteins by...

Friedman J, Lelkes P, Lavie E, ROSENHECK K, Schneeweiss F, Schneider A
J Neurochem
. 1985 May;
44(5):1391-402.
PMID: 3989537
Changes in plasma membrane potential of isolated bovine adrenal chromaffin cells were measured independently by two chemical probe methods and related to corresponding effects on catecholamine secretion. The lipophilic cation...

Harish O, Levy R, ROSENHECK K, Oplatka A
Biochem Biophys Res Commun
. 1984 Mar;
119(2):652-6.
PMID: 6712650
The exocytosis of catecholamines by chromaffin cells following stimulation (e.g. by acetylcholine) is accompanied by a rise in the level of intracellular free Ca2+. Actually, secretion can be induced merely...
