Ca2+ Signaling in the Near Plasma Membrane Microdomain of Non-Excitable Cells
(2011-02-01)Calcium is the most versatile second messenger and plays fundamental roles in orchestrating enzyme secretion in exocrine acinar cells. Previous studies in excitable cells demonstrated the existence of high Ca2+ microdomains. ... -
Calcium Triggered Synaptic Vesicle Exocytosis
(2007-08-08)Neurotransmitter release is triggered by the action potential induced influx of Ca 2+ into nerve terminals. One of the central questions in neuroscience is how Ca 2+ promotes synaptic vesicles from rest to fusion leading ... -

Optical Quantal Analysis of Evoked and Spontaneous Single-Vesicle Fusion
(2014-07-14)Synaptic vesicle recycling is critical for the maintenance and proper function of neurotransmission. Neurotransmission can proceed through action-potential evoked vesicle fusion where, upon depolarization, Ca2+ enters the ... -
Reciprocal Interactions of STIM1 with Orai1 and L-Type Ca2+ Channels in Cardiac Myocytes
(2015-01-26)BACKGROUND: Pathological cardiac hypertrophy can be triggered by abnormal Ca2+ levels. It has been shown that the mechanisms governing context-dependent changes in Ca2+ influx are linked to stromal interaction molecule 1 ... -

Spontaneous Neurotransmission as a Driver of Calcium Signaling
(2016-09-20)Spontaneous neurotransmission is a stochastic mode of neurotransmitter release that is not coupled to action potential arrival at the presynapse. Recent evidence has shed light upon the presynaptic and vesicular fusion ... -
Standard Calcium Supplementation May Increase Kidney Stone Risk: A Study in Women with Postmenopausal Osteoporosis
(2014-02-04)INTRODUCTION: The US prevalence of kidney stones has increased from 2.6% in 1972 to 8.4% in 2010.The majority of stones contain calcium (Ca) with hypercalciuria (hCa) highly associated with stone formation. Postmenopausal ... -
Studies on Plasma Membrane Proteins Involved in Membrane Traffic: Syntaxins and E-Syts
(2007-05-22)Fusion of synaptic vesicles is catalyzed by SNARE complex assembly which requires that the SNARE proteins syntaxin-1A and -1B, two isoforms of syntaxin-1, switch from a 'closed' to an 'open' conformation. To test the ... -
