Calcium Ions Signaling: Targets for Attack and Utilization by Viruses

open access: yesFrontiers in Microbiology, 2022
Calcium, as a second intracellular messenger, participate in various physiological and biochemical processes, including cell growth and proliferation, energy metabolism, information transfer, cell death, and immune response.

Gray matter NG2 cells display multiple Ca2+-signaling pathways and highly motile processes [PDF]

open access: yes, 2011
NG2 cells, the fourth type of glia in the mammalian CNS, receive synaptic input from neurons. The function of this innervation is unknown yet. Postsynaptic changes in intracellular Ca2+-concentration ([Ca2+]i) might be a possible consequence. We employed

Hydrogen sulfide induces Ca2+ release from the endoplasmic reticulum and suppresses ATP-induced Ca2+ signaling in rat spinal cord astrocytes [PDF]

open access: yes, 2021
Hydrogen sulfide (H2S) has a variety of physiological functions. H2S reportedly increases intracellular Ca2+ concentration ([Ca2+];) in astrocytes. However, the precise mechanism and functional role of this increase are not known.

Ca2+ Microdomains in T-Lymphocytes

open access: yesFrontiers in Oncology, 2017
Early Ca2+ signaling is characterized by occurrence of Ca2+ microdomains formed by opening of single or clusters of Ca2+ channels, thereby initiating first signaling and subsequently activating global Ca2+ signaling mechanisms. However, only few data are

Ontogeny of purinergic receptor-regulated Ca2+ signaling in mouse cortical collecting duct epithelium [PDF]

open access: yes, 2002
Changes in ATP-induced increase in {[}Ca2+], during collecting duct ontogeny were studied in primary monolayer cultures of mouse ureteric bud (UB) and cortical collecting duct (CCD) cells by Fura-PE3 fluorescence ratio imaging.

ER localized bestrophin1 activates Ca2+ dependent ion channels TMEM16A and SK4 [PDF]

open access: yes, 2009
Bestrophins form Ca2+ activated Cl- channels and regulate intercellular Ca2+ signaling1. We demonstrate that bestrophin 1 is localized in the endoplasmic reticulum (ER), where it physically interacts with stromal interacting molecule 1 (Stim1), the ER ...

Cytosolic and mitochondrial Ca2+ signaling in procoagulant platelets

open access: yesPlatelets, 2021
Platelets are the major cellular contributor to arterial thrombosis. However, activated platelets form two distinct subpopulations during thrombosis. Pro-aggregatory platelets aggregate to form the main body of the thrombus.

Information transfer in signaling pathways : a study using coupled simulated and experimental data [PDF]

open access: yes, 2008
Background: The topology of signaling cascades has been studied in quite some detail. However, how information is processed exactly is still relatively unknown.

Endothelin-Induced Sarcoplasmic Reticulum Calcium Depletion Waves in Vascular Smooth Muscle Cells [PDF]

open access: yes, 2011
Agonist-stimulated waves of elevated cytoplasmic Ca2+ concentration ([Ca2+]i ) regulate blood vessel tone and vasomotion in vascular smooth muscle. Previous studies employing cytoplasmic Ca2+ indicators revealed that these Ca2+ waves were generated by a ...

In vitro Activation of mouse oocytes through intracellular Ca2+ regulation

open access: yesJournal of Human Reproductive Sciences, 2020
Background: Ca2+ signaling pathway is suggested to play an essential role in mediating oocyte maturation. Aims: The aim of this study was to evaluate intracellular Ca2+ of resistant immature oocytes that failed to resume meiosis following subsequent in ...
