Cytosolic calcium oscillation signaling in guard cell

Plant Science, 2004
Abstract Calcium signaling has been established to play a very important role in stomatal movements. More and more attentions have now been focused on cytosolic calcium ([Ca2+]cyt) oscillation in guard cell. It is still not clear how [Ca2+]cyt oscillation occurs and how it is decoded.

Oscillation and noise determine signal transduction in shark multimodal sensory cells

Nature, 1994
Oscillating membrane potentials that generate rhythmic impulse patterns are considered to be of particular significance for neuronal information processing. In contrast, noise is usually seen as a disturbance which limits the accuracy of information transfer.

Calcium signalling in non-excitable cells: Notes on oscillations and store refilling

Cell Calcium, 1989
Technical advances in studying cellular calcium concentrations, and discoveries about many aspects of signal transduction have transformed this field of biology since this Journal was launched a decade ago. At that time monitoring of the key variable, cytoplasmic free Ca2+ concentration [Ca2+]i, was possible with aequorin or arsenazo ill mainly in ...

Adenylate cyclase activity oscillations as signals for cell aggregation in Dictyostelium discoideum

Nature, 1977
As well as acting as a chemotactic factor1 cyclic AMP stimulates cells of Dictyostelium discoideum to differentiate after the end of growth into aggregation-competent cells. These differentiation signals have a temporal pattern : pulses are efficient signals, whereas continuous administration of cyclic AMP may even have an adverse effect2,3.

Characterization of Calcium signals and oscillations in dendritic cells in vivo in response to pathogens

The Journal of Immunology, 2023
Abstract Dendritic cells (DCs) are disseminated throughout organisms and serve as sentinels, organizing immune responses to infection, tissue damage, and cancer. DCs play a crucial role bridging innate and adaptive immune systems and elicit a tailored adaptive immune response to the types of threats they encounter. Manipulation of DCs is

Small signal cell stability with focus on inter-cell oscillations in the web-of-cells framework

2017 IEEE 58th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON), 2017
The paper aims at describing observables used in small signal stability assessment based on Energy-Sorted Prony's method focusing at area and inter-area level of the power system. Presented research studies are based on a new way of power system operation, namely Web-of-cell concept, devised within FP7 IRP ELECTRA.
