Regulation of Protein Secretion Systems Mediated by Cyclic Diguanylate in Plant-Interacting Bacteria

open access: yesFrontiers in Microbiology, 2019
The ubiquitous second messenger cyclic diguanylate (c-di-GMP) is involved in the regulation of different processes in bacteria. In phytopathogens, intracellular fluctuations in the concentration of this molecule contribute to the lifestyle switching from

Modeling Human Ad Hoc Coordination

open access: yes, 2016
Whether in groups of humans or groups of computer agents, collaboration is most effective between individuals who have the ability to coordinate on a joint strategy for collective action.

CXCL12 chemokine and GABA neurotransmitter systems crosstalk and their putative roles

open access: yesFrontiers in Cellular Neuroscience, 2014
Since CXCL12 and its receptors, CXCR4 and CXCR7, have been found in the brain, the role of this chemokine has been expanded from chemoattractant in the immune system to neuromodulatory in the brain.

Higgs Multiplets of the Quark-Lepton Family Group

open access: yes, 2011
It is shown that realistic models can be constructed in which the Standard Model Higgs field is in a non-trivial multiplet of a non-abelian family group of the quarks and leptons.

Cyclic Diguanylate Signaling Proteins Control Intracellular Growth of Legionella pneumophila

open access: yesmBio, 2011
Proteins that metabolize or bind the nucleotide second messenger cyclic diguanylate regulate a wide variety of important processes in bacteria. These processes include motility, biofilm formation, cell division, differentiation, and virulence.

Interaction between Calcium and Actin in Guard Cell and Pollen Signaling Networks

open access: yesPlants, 2013
Calcium (Ca2+) plays important roles in plant growth, development, and signal transduction. It is a vital nutrient for plant physical design, such as cell wall and membrane, and also serves as a counter-cation for biochemical, inorganic, and organic ...

Magnetic dipole moment of neutral particles from quantum corrections at two-loop order

open access: yes, 2013
The tentative gamma-ray line in the Fermi data at ~135 GeV motivates a dark matter candidate that couples to photons through loops of charged messengers.

Effects of clonidine and other imidazole-receptor binding agents on second messenger systems and calcium influx in bovine adrenal chromaffin cells.

open access: yesBiochemical Pharmacology, 1991
Clonidine and related imidazoline compounds bind to alpha 2-adrenergic as well as to newly described non-adrenergic imidazole/imidazoline receptors in brain and peripheral tissues.

A novel transcriptional regulator, CdeR, modulates the type III secretion system via c-di-GMP signaling in Dickeya dadantii

open access: yesMicrobiology Spectrum
Dickeya dadantii is a bacterial pathogen that causes soft rot disease in many plant species worldwide, including temperate, subtropical, and tropical regions. This bacterium employs the type III secretion system (T3SS) to manipulate host immune responses.
