Regulated exocytosis of secretory granules or dense-core granules has been examined in
many well-characterized cell types including neurons, neuroendocrine, endocrine, exocrine …

abstract The chromaffin cell has been used as a model to characterize releasable
components present in secretory granules and to understand the cellular mechanisms …

Astrocytes, a subtype of glial cells, have numerous characteristics that were previously
considered exclusive for neurons. One of these characteristics is a cytosolic [Ca2+] …

Abstract LOW-MOLECULAR-WEIGHT GTP-binding proteins (small G proteins) of the Rab
family have been proposed to act as central regulators of vesicular traffic1, 2, and proteins of …

I. Introduction O VER the last two decades it has become evident that intracellular Ca2+
signals are critically important for the control of cellular activities including excitability …

We have monitored cytosolic [Ca 2+] with fura-2 and exocytosis by measuring the
membrane capacitance, and we have studied the influence of cytosolic [Cal 2+] on secretion …

In order to understand exocytosis and endocytosis, it is necessary to study these processes
directly. An elegant way to do this is by measuring plasma membrane capacitance (C m), a …

The patch-clamp technique has been used to measure changes in membrane capacitance
(Cm) of bovine lactotrophs in order to monitor fluctuations in cell surface area associated …

The term exocytosis [99] describes the mechanism by which eukaryotic cells secrete
prepackaged materials contained in membrane-bound vesicles or granules to the exterior …

Many cells release preformed material contained in secretory granules by exocytosis.
Exocytosis is a specialized means of secretion in which the granules fuse with the plasma …
