Dependence of photolysis-induced long-lasting MF depression on protein phosphatases. A: photolysis had no effect on MF responses in 7 of 8 experiments inhibiting phosphatase 1/2A with calyculin A (1 μm) or phosphatase 2B with cyclosporin A (200 μm). Cumulative probability distributions for these results are plotted along with results of 30 photolysis experiments done without phosphatase inhibition. Data symbols distinguish experiments showing statistically significant (by ANOVA) potentiation (○), depression (△), or no change (●). B: PPF was not altered by photolysis in cells treated with phosphatase inhibitors (filled bars). Untreated cells in which photolysis induced long-lasting depression were also unaffected by photolysis (open bars, same data as filled bars in Fig. 4C). C: [Ca2+]i elevation was similar in these 2 groups of cells.
