Figure 3


Fig. 3. (A–E) pHi changes induced by bath application of 10 mmol l–1 cAMP (A), 10 µmol l–1 8-CPT-cAMP (B), 100 µmol l–1 of the adenylyl cyclase inhibitor forskolin (C) and 500 µmol l–1 of the phosphodiesterase inhibitor IBMX (D). These experiments show that increases in intracellular cAMP concentration mimic the acidifying effect of 5-HT stimuli. (E) Quantitative analysis of the experiments. Data are means ± s.e.m.; the number of experiments is given in parentheses.
