Figure 8. Effects of P2X receptor antagonists on ATP- and αβ-me-ATP-elicited postsynaptic currents.
A, typical traces of 10−4m ATP-elicited postsynaptic currents in the absence of any antagonists (a), and in the presence of 10−7m TNP-ATP (b) and both 10−7m TNP-ATP and 10−5m PPADS (c). In d, ATP-elicited postsynaptic current was clearly recovered after washing out antagonists. B, typical traces of 10−4mαβ-me-ATP-elicited postsynaptic currents in the absence of any antagonists (a), and in the presence of 10−7m TNP-ATP (b). In c, αβ-me-ATP-elicited postsynaptic current was clearly recovered after washing out TNP-ATP.
