Long Signaling Cascades Tend to Attenuate Retroactivity
(Cell Press, 2011-04)
Signaling pathways consisting of phosphorylation/dephosphorylation cycles with no explicit feedback allow signals to propagate not only from upstream to downstream but also from downstream to upstream due to retroactivity ...
SLAM and CD31: Signaling molecules involved in cytokine secretion during the development of innate and adaptive immune responses
(Elsevier, 2007-02)
Immune cells are modulated through the crosslinking of receptors named "immunoreceptors". Ligation of immunoreceptors by their ligands induces a tyrosine-phosphorylation signal that is essential for cell activation or ...
The shade-avoidance syndrome: Multiple signals and ecological consequences
(Wiley Blackwell Publishing, Inc, 2017-01)
Plants use photoreceptor proteins to detect the proximity of other plants and to activate adaptive responses. Of these photoreceptors, phytochrome B (phyB), which is sensitive to changes in the red (R) to far-red (FR) ratio ...
Retrograde bone morphogenetic protein signaling shapes a key circadian pacemaker circuit
(Society For Neuroscience, 2013-01)
The neuropeptide pigment-dispersing factor (PDF) synchronizes molecular oscillations within circadian pacemakers in the Drosophila brain. It is expressed in the small ventral lateral neurons (sLNvs) and large ventral lateral ...
Analysis of a Signal Transmission in a Pair of Izhikevich Coupled Neurons
(World Scientific, 2020-12)
Individual neuron models give a comprehensive explanation of the behaviour of the electrical potential of cell membranes. These models were and are a source of constant analysis to understand the functioning of, mainly, ...
Molecular Basis of Redox Signaling
(Landes Bioscience, 2019-05)
Oxidants are produced in physiological and pathological conditions. The production of reactive nitrogen and oxygen species (RNS and ROS, respectively) can lead to vastly different cellular outcomes depending on their ...
A novel time stamping data acquisition system using a digital oscilloscope for single counting photons
(Institute of Electrical and Electronics Engineers Inc., 2017-12)
In this paper we present an algorithm of signal processing that allows the use of a PC-based oscilloscope in order to count events with a time stamping register. This novel application has a direct use on recording of ...
The GTPase-activating protein Rap1GAP: A new player to modulate Ret signaling
(Inst Biochemistry & Cell Biology, 2011-02)
Auxin and salicylic acid signalings counteract during the adaptive response to stress
(Taylor & Francis, 2011-03)
In a previous publication, we performed a phenotypic characterization of Arabidopsis auxin receptor mutants grown under oxidative and salt stresses. In particular, the double mutant for TIR1 and AFB2 receptors, tir1 afb2 ...
Adaptive local iterative filtering: A promising technique for the analysis of nonstationary signals
(American Geophysical Union, 2017-12)
Many real-life signals and, in particular, in the space physics domain, exhibit variations acrossdifferent temporal scales. Hence, their statistical momenta may depend on the time scale at which the signal is studied. To ...
