Inward rectifying K channel activity was observed in the luminal membrane of the marginal cell by use of the patch clamp technique. When pipette solution contained 150 mM KCl, the current reversed at 10.2 +/- 8.8 mV (N = 27). The channel current showed multiple subconductance levels and depolarization activated the channel very slowly (order of seconds). Current-voltage relationships in cell-attached mode showed inward rectification. The calculated slope conductance of inward and outward… CONTINUE READING
