Calcium ions as extracellular messengers
The capacity to regulate their internal ionic composition is a fundamental property of free-living terrestrial organisms (Stewari and Broadus, 1987). This is accomplished by adjusting the movement of ions or water (or both) between cells and various extracellular compartments, including those communicating with the external environment. Of the complement of inorganic ions in such organisms, Ca2...

متن کاملExtracellular Vesicles Act as Messengers of Macrophages Sensing Atherogenic Stimuli.
The release of vesicles by cells into the extracellular space is found in many aspects of biology, and such extracellular vesicles (EVs) are gaining increasing attention in diverse areas of biomedical research. EVs represent a heterogeneous population differing in size, number, and composition that are dependent on the type and activation state of the parental cells that release them. Based on ...
متن کاملProtons as Intercellular Messengers
Muscle contractions are driven by neurotransmitters released at neuromuscular junctions. In this issue, Beg et al. (2008) report that protons, in the absence of neurotransmitters and neurons, can stimulate muscle contractions involved in the defecation cycle of the worm Caenorhabditis elegans. Their results identify protons as a new intercellular messenger and suggest that proton-mediated inter...
متن کاملNeutrinos as cosmic messengers
I briefly review the current status of neutrino oscillation parameters and discuss the role of neutrinos as cosmological probes, that could possibly induce the baryon asymmetry as well as the dark matter in the Universe. I comment on the origin of neutrino masses in seesaw-type and low-scale models and mention some of their laboratory signals. STATUS OF NEUTRINO OSCILLATIONS The discovery of ne...
