Procedures to characterize and study P2Z/P2X7 purinoceptor: flow cytometry as a promising practical, reliable tool.
The expression of P2Z/P2X7 purinoceptor in different cell types is well established. This receptor is a member of the ionotropic P2X receptor family, which is composed by seven cloned receptor subtypes (P2X1 - P2X7). Interestingly, the P2Z/P2X7 has a unique feature of being linked to a non-selective pore which allows the passage of molecules up to 900 Da depending on the cell type. Early studie...
متن کاملMaitotoxin activates a nonselective cation channel and a P2Z/P2X7-like cytolytic pore in human skin fibroblasts.
Maitotoxin (MTX), a potent cytolytic agent, activates Ca2+ entry via nonselective cation channels in virtually all types of cells. The identity of the channels involved and the biochemical events leading to cell lysis remain unknown. In the present study, the effect of MTX on plasmalemmal permeability of human skin fibroblasts was examined. MTX produced a time- and concentration-dependent incre...
متن کاملGreater learnability is not sufficient to produce cultural universals.
Looking across human societies reveals regularities in the languages that people speak and the concepts that they use. One explanation that has been proposed for these "cultural universals" is differences in the ease with which people learn particular languages and concepts. A difference in learnability means that languages and concepts possessing a particular property are more likely to be acc...
متن کاملMyocardin is sufficient for a smooth muscle-like contractile phenotype.
BACKGROUND Myocardin (Myocd) is a strong coactivator that binds the serum response factor (SRF) transcription factor over CArG elements embedded within smooth muscle cell (SMC) and cardiac muscle cyto-contractile genes. Here, we sought to ascertain whether Myocd-mediated gene expression confers a structural and physiological cardiac or SMC phenotype. METHODS AND RESULTS Adenoviral-mediated ex...
متن کاملPhospholipase D activation by P2Z-purinoceptor agonists in human lymphocytes is dependent on bivalent cation influx.
The role of bivalent cations in ATP-stimulated phospholipase D (PLD) activity was investigated in human leukaemic lymphocytes. Cells were labelled with [3H]oleic acid and incubated with extracellular ATP or benzoylbenzoic ATP in the presence of 1 mM Ca2+ and butanol, and PLD activity was assayed by the accumulation of [3H]phosphatidylbutanol ([3H]PBut). ATP stimulated PLD activity in a dose-dep...
