Figure 5. L-channel Ca2+ current mediates the stress effect on DSI.

Figure 5

(A and B) Bath application of the L-channel blocker, nifedipine (Nif, 10 μM), did not affect DSI duration in control (A, n=6) while it decreased DSI duration in stressed cells (B, n=9). Representative traces from a control (A) and a stressed (B) cell are shown above. Cal. bar: 20s, 200pA. (C) Group data, %DSI; each circle represents one cell. Nif reduced DSI in stressed cells, but not in control cells; * p<0.05. (D) Group data, DSI τd; each circle represents one cell. Nif reduced τd in stressed cells, but not in control cells, * p<0.05.
