(A) QPCR data showed that the induction of tau downregulated the mRNA level of Kv2.1. But no change was produced after the transfection of an empty vector (mock) of tau (n = 8). The * denoted p<0.05 compared with control Kv2.1 (B) The representative current traces of Kv2.1 before and after tau transfection. Currents were evoked by a 500 ms long voltage pulse to potentials from -80 mV to +60 mV at a holding potential of -80 mV. (C) Current–voltage (I-V) relations of Kv2.1 currents in the absence and presence of tau. (D) The statistic analysis of effects of tau transfection on macroscopic Kv2.1 currents in HEK293 cells (n = 8). The * denoted p<0.05 compared with Kv2.1 currents.
