Kainate inhibits the exchange of D-aspartate into guinea-pig cerebrocortical synaptosomes. Kainate inhibits the Ca2+-independent efflux of endogenous glutamate in the presence of a trapping system for the released amino acid but potentiates a Ca2+-independent net efflux of endogenous and labelled glutamate and aspartate in the absence of the trap.(More)
ATP and UTP did not evoke [Ca2+]i signals in rat foetal lung epithelial cells grown on glass but elicited clear responses in cells grown into functionally polarised epithelia on permeable supports. Moreover, P2Y2 receptor mRNA could not be detected in cells on glass by the polymerase chain reaction but this mRNA species was clearly expressed by polarised(More)
1 Rat foetal distal lung epithelial cells were plated onto permeable supports where they became integrated into epithelial sheets that spontaneously generated short circuit current (ISC). 2 Apical ATP (100 microM) evoked a transient fall in ISC that was followed by a rise to a clear peak which, in turn, was succeeded by a slowly developing decline to a(More)
