Triggering and augmentation mechanisms, granule pools, and biphasic insulin secretion


TK Bratanova-Tochkova, H Cheng, S Daniel, … - Diabetes, 2002 - Am Diabetes Assoc
The insulin secretory response by pancreatic ß-cells to an acute "square wave"
stimulation by glucose is characterized by a first phase that occurs promptly
after exposure to glucose, followed by a decrease to a nadir, and a ...

A subset of 50 secretory granules in close contact with L-type Ca2+ channels accounts for …

S Barg, L Eliasson, E Renström, P Rorsman - Diabetes, 2002 - Am Diabetes Assoc
Capacitance measurements were applied to mouse pancreatic ß-cells to elucidate
the cellular mechanisms underlying biphasic insulin secretion. We report here
that only <50 of the ß-cell's >10,000 granules are immediately available ...

Glucose-stimulated signaling pathways in biphasic insulin secretion


SG Straub, GWG Sharp - Diabetes/Metabolism Reviews - interscience.wiley.com
Glucose-stimulated biphasic insulin secretion involves at least two signaling
pathways, the KATP channel-dependent and KATP channel-independent pathways,
respectively. In the former, enhanced glucose metabolism increases the ...

Fast insulin secretion reflects exocytosis of docked granules in mouse pancreatic B-cells


CS Olofsson, SO Göpel, S Barg, J … - Pflügers Archiv European Journal of Physiology, 2002 - Springer
Abstract A readily releasable pool (RRP) of granules has been proposed to
underlie the first phase of insulin secretion. In the present study we combined
electron mi- croscopy, insulin secretion measurements and recordings of ...

Insulin granule dynamics in pancreatic beta cells


P Rorsman, E Renström - Diabetologia, 2003 - Springer
Glucose-induced insulin secretion in response to a step increase in blood
glucose concentrations follows a bi- phasic time course consisting of a rapid
and transient first phase followed by a slowly developing and sus- tained ...

The Cell Physiology of Biphasic Insulin Secretion.


P Rorsman, L Eliasson, E Renström, J … - News in physiological sciences: an international …, 2000 - ncbi.nlm.nih.gov
Glucose-stimulated insulin secretion consists of a transient first phase
followed by a sustained second phase. Diabetes (type II) is associated with
abnormalities in this release pattern. Here we review the evidence that ...

Signals and pools underlying biphasic insulin secretion

- diabetesjournals.org
JC Henquin, N Ishiyama, M Nenquin, MA … - Diabetes, 2002 - Am Diabetes Assoc
Rapid and sustained stimulation of β-cells with glucose induces biphasic
insulin secretion. The two phases appear to reflect a characteristic of
stimulus-secretion coupling in each β-cell rather than heterogeneity in ...

Identification of the docked granule pool responsible for the first phase of glucose-stimulated …

- diabetesjournals.org [PDF] 
S Daniel, M Noda, SG Straub, GW Sharp - Diabetes, 1999 - Am Diabetes Assoc
The mechanisms underlying the first phase of glucose- stimulated insulin
release, the deterioration of which marks the early stages of both type 1 and
type 2 dia- betes, are essentially unknown. Among many hypothe- ses, one ...

Fast exocytosis with few Ca2+ channels in insulin-secreting mouse pancreatic B cells

- nih.gov [PDF] 
S Barg, X Ma, L Eliasson, J Galvanovskis, SO … - Biophysical Journal, 2001 - Elsevier
The association of L-type Ca 2+ channels to the secretory granules and its
functional significance to secretion was investigated in mouse pancreatic B
cells. Nonstationary fluctuation analysis showed that the B cell is ...
