Figure 1. ATP and BzATP induce membrane currents in cultured rat Schwann cells.

Figure 1

The illustrated examples from four different Schwann cells are representative for the effects of ATP and BzATP. A and B, membrane currents induced by slow voltage ramps from -140 to 80 mV in 2 s were recorded from two different cultured rat Schwann cells before and during bath application of ATP (1 mM) and BzATP (150 μM). Note the different scaling of the current axes. C and D, the membranes of these Schwann cells were voltage clamped at a constant holding potential (Em) and changes in the holding current were recorded during bath application of different P2 nucleotide receptor agonists.
