Lysophosphatidic acid-operated K+ channels.
Lysophosphatidic acid (LPA) is an abundant cellular lipid with a myriad of biological effects. It plays an important role in both inter- and intracellular signaling. Activation of the LPA1-3 G-protein-coupled receptors explains many of the extracellular effects of LPA, including cell growth, differentiation, survival, and motility. However, LPA also acts intracellularly, activating the nuclear ...
متن کاملLysophosphatidic acid triggers calcium entry through a non-store-operated pathway in human neutrophils.
Lysophosphatidic acid (LPA) is a bioactive lipid, which is structurally similar to sphingosine 1-phosphate (S1P) and which can mobilize Ca2+ in multiple cell types. We recently showed that S1P induces Ca2+ entry directly through store-operated Ca2+ entry (SOCE) channels in human polymorphonuclear neutrophils (PMN). We therefore examined the mechanisms by which LPA induces intracellular Ca2+ mob...
متن کاملStore-operated calcium channels.
Store-operated calcium channels (SOCs) are a major pathway for calcium signaling in virtually all metozoan cells and serve a wide variety of functions ranging from gene expression, motility, and secretion to tissue and organ development and the immune response. SOCs are activated by the depletion of Ca(2+) from the endoplasmic reticulum (ER), triggered physiologically through stimulation of a d...
متن کاملStore-operated calcium channels.
In electrically nonexcitable cells, Ca(2+) influx is essential for regulating a host of kinetically distinct processes involving exocytosis, enzyme control, gene regulation, cell growth and proliferation, and apoptosis. The major Ca(2+) entry pathway in these cells is the store-operated one, in which the emptying of intracellular Ca(2+) stores activates Ca(2+) influx (store-operated Ca(2+) entr...
متن کاملLysophosphatidic acid receptors.
Lysophosphatidic acid (LPA) is a simple bioactive phospholipid with diverse physiological actions on many cell types. LPA induces proliferative and/or morphological effects and has been proposed to be involved in biologically important processes including neurogenesis, myelination, angiogenesis, wound healing, and cancer progression. LPA acts through specific G protein-coupled, seven-transmembr...
