Calcium ion as intracellular messenger and cellular toxin.
Ca2+ serves a nearly universal intracellular messenger function in cell activation, but excess Ca2+ is also a cellular toxin. The possibility of Ca2+ intoxication is minimized by an elaborate autoregulatory system in which changes in Ca2+ influx rate across the plasma membrane are rapidly compensated for by parallel changes in Ca2+ efflux rate. By this mean, cellular Ca2+ homestasis is maintain...
متن کامل[The calcium messenger system].
Calcium ion acts as an intracellular messenger of various types of extracellular signals including hormones, neurotransmitters, cytokines and growth factors. Recent advances in the research of the calcium messenger system have provided informations as to the structure and function of many proteins involved in the messenger system. Also, technical advances in the measurement of the dynamics of c...
متن کاملAnandamide as an intracellular messenger regulating ion channel activity.
The endocannabinoid anandamide (N-arachidonoylethanolamine) was proposed to be an extracellular retrograde messenger, which regulates excitability of neurons by cannabinoid CB1 receptor-dependent inhibition of neurotransmitter release. Recent findings indicate that the neuromodulatory actions of anandamide might be more complex. Anandamide has been shown to directly modulate various ion channel...
متن کاملNAADP as an intracellular messenger regulating lysosomal calcium-release channels.
Recent studies into the mechanisms of action of the Ca(2+)-mobilizing messenger NAADP (nicotinic acid-adenine dinucleotide phosphate) have demonstrated that a novel family of intracellular Ca(2+)-release channels termed TPCs (two-pore channels) are components of the NAADP receptor. TPCs appear to be exclusively localized to the endolysosomal system. These findings confirm previous pharmacologic...
متن کاملCalcium Signaling: NAADP Ascends as a New Messenger
NAADP is now established as a Ca(2+) messenger by recent studies which have shown that it is active in various cells, identified the targeted Ca(2+) stores and demonstrated a stimulus-activated increase in its endogenous levels.
