Action potentials evoke calcium transients in dendrites of neocortical pyramidal neurons with time constants of < 100 ms at physiological temperature. This time period may not be sufficient for inflowing calcium ions to equilibrate with all present Ca2+-bi ...
A model of Ca2+ dynamics in spines of CA1 hippocampal neurons is presented. In contrast to traditional models, which concentrate on the effects of Ca2+ influx, diffusion, buffering, and extrusion, we also consider the additional effect of intracellular ...
Many hormones, growth factors and neurotransmitters stimulate the production of inositol 1,4,5-trisphosphate evoking the release of calcium from intracellular stores. The depletion of these intracellular calcium stores subsequently activates a voltage-inde ...
Depletion of intracellular calcium stores activates the plasma membrane capacitative calcium entry pathway in many cell types. The nature of the signal that couples the depletion of the intracellular calcium stores to the activation of the plasma membrane ...
Dendrites of rat neocortical layer V pyramidal neurons were loaded with the Ca2+ indicator dye Calcium Green-1 (CG-1) or fluo-3, and the mechanisms which govern action potential (AP)-evoked transient changes in dendritic cytosolic Ca2+ concentration ([C ...
The goal of the present study was to analyze the intercellular calcium communication between smooth muscle cells (SMCs) and endothelial cells (ECs) by simultaneously monitoring artery diameter and intracellular calcium concentration in a rat mesenteric art ...
Capacitative calcium entry is a major pathway through which intracellular calcium stores are refilled after stimulation. It has been suggested that the protein encoded by the transient receptor potential (trp) gene expressed in Drosophila photoreceptors ma ...
The regulation of cytosolic-free calcium concentration of smooth-muscle and endothelial cells was mainly studied on cultured cells where the cross talk between these two coupled cell types is lost. In the present study, the cytosolic-free calcium concentra ...
Human immunodeficiency virus Nef plays an important role in AIDS pathogenesis. In addition to the well known down-regulation of cell surface receptors (CD4, MHCI), Nef is able to alter cellular signaling. Of particular interest for this study is the abilit ...
Capacitative Ca2+ entry produces the very rapid light response in Drosophila photoreceptors; studies using this amenable system may help unravel the machinery and mechanisms that underlie this Ca2+-entry pathway. ...
