Friend and foe: β-cell Ca2+ signaling and the development of diabetes

open access: yesMolecular Metabolism, 2019
Background: The divalent cation Calcium (Ca2+) regulates a wide range of processes in disparate cell types. Within insulin-producing β-cells, increases in cytosolic Ca2+ directly stimulate insulin vesicle exocytosis, but also initiate multiple signaling ...

Alteration of expression of Ca2+ signaling proteins and adaptation of Ca2+ signaling in SERCA2+/- mouse parotid acini. [PDF]

open access: yes, 2008
PURPOSE: The sarco/endoplasmic reticulum Ca2+-ATPase (SERCA), encoded by ATP2A2, is an essential component for G-protein coupled receptor (GPCR)-dependent Ca2+ signaling.

Calcium specificity signaling mechanisms in abscisic acid signal transduction in Arabidopsis guard cells

open access: yeseLife, 2015
A central question is how specificity in cellular responses to the eukaryotic second messenger Ca2+ is achieved. Plant guard cells, that form stomatal pores for gas exchange, provide a powerful system for in depth investigation of Ca2+-signaling ...

Elevated Ca2+ at the triad junction underlies dysregulation of Ca2+ signaling in dysferlin-null skeletal muscle

open access: yesFrontiers in Physiology, 2022
Dysferlin-null A/J myofibers generate abnormal Ca2+ transients that are slightly reduced in amplitude compared to controls. These are further reduced in amplitude by hypoosmotic shock and often appear as Ca2+ waves (Lukyanenko et al., J. Physiol., 2017).

Reduced endogenous Ca2+ buffering speeds active zone Ca2+ signaling [PDF]

open access: yes, 2015
Fast synchronous neurotransmitter release at the presynaptic active zone is triggered by local Ca2+ signals, which are confined in their spatiotemporal extent by endogenous Ca2+ buffers.

The Role of Ca2+ Signaling in Aging and Neurodegeneration: Insights from Caenorhabditis elegans Models

open access: yes, 2020
Ca2+ is a ubiquitous second messenger that plays an essential role in physiological processes such as muscle contraction, neuronal secretion, and cell proliferation or differentiation.

6-Gingerol alleviates acute graft-versus-host disease by regulating Th17/Treg differentiation via the P2Y13/Ca2+ signaling pathway

open access: yes陆军军医大学学报
Objective Acute graft-versus-host disease (aGVHD) is a common immunological complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT). This study aims to investigate the intervention effects of 6-gingerol on aGVHD and explore

Allosteric Regulation of NCLX by Mitochondrial Membrane Potential Links the Metabolic State and Ca2+ Signaling in Mitochondria

open access: yesCell Reports, 2018
Summary: Calcium is a key regulator of mitochondrial function under both normal and pathological conditions. The mechanisms linking metabolic activity to mitochondrial Ca2+ signaling remain elusive, however.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Regenerative Calcium Currents in Renal Primary Cilia

open access: yesFrontiers in Physiology, 2022
Polycystic kidney disease (PKD) is a leading cause of end-stage renal disease. PKD arises from mutations in proteins, one a Ca2+-conducting channel, expressed in the primary cilia of renal epithelial cells.
