Modulation of KTX-Sp4 on endogenous voltage-gated potassium channels. a Representative traces illustrate that 100 nM KTX-Sp4 inhibited the Kv1.3 current in a Jurkat T cell reversibly. b Concentration–response curve of KTX-Sp4 inhibition of Kv1.3 current in Jurkat T cells. Currents were normalized to the control and fitted by a Hill equation; IC50 value was 235.02 ± 3.36 nM (n = 8). c Current traces of voltage-gated potassium channels in DRG cells in the absence (control) or presence of 1 μM KTX-Sp4
