26946358 The results suggest a role of PrP(C) in proteostasis, dysfunctions of which may be involved in the pathogenesis of neurodegenerative diseases such as TSE and Alzheimer's Disease.
26865631 These findings provide new insights in understanding the contribution of the salt bridge between Asp-85 and Arg-309 and its structurally coupled beta2,3-sheet to the function of P2X4 receptors.
26101220 P2X4 and calmodulin form a complex at endolysosomal membrane where P2X4 activation recruits calmodulin to promote fusion and vacuolation in a Ca(2+)-dependent fashion.
25938443 Fndings support role for P2X7 and P2X4 coupled to induction of inflammatory molecules in modulating high glucose and palmitate-induced endothelial cell activation and dysfunction.
25563726 This study demonstrates a major physiological finding that the shear-induced effects on endothelial KLF2 axis are in part dependent on ATP release and P2X4, a previously unidentified mechanism.
25480524 It appears to mediate the cells' response to extracellular ATP. Although Ca2thorn influx via P2X1 receptor is necessary for alpha-synuclein accumulation.
24935743 Using pHluorin, P2X4 was found to be expressed on the plasma membrane and within subcellular compartments in hippocampus.
24845338 These data suggest that vascular smooth muscle cells from human gastro-omental arteries express P2X1 and P2X4 receptor subunits
24817123 the lysosome-localized P2X4 may play specific roles in membrane trafficking of acidic organelles in mammalian cells.
23959888 Data indicate that MgATP2- activates P2X1 and P2X3, but not P2X2 and P2X4 receptors.
