Enhancement by BFA of A23187-, and TG-induced decrease of [³H]-STX binding capacity in adrenal chromaffin cells. Cells were treated with DMSO, 1 μM A23187 or 100 nM TG for 6 or 12 h in the absence (None) or presence of 10 μg ml⁻¹ BFA, and subjected to [³H]-STX binding assay. Mean±s.e.mean (n=5). ^*P<0.05, significant decrease by BFA, A23187 or TG; #P<0.05, compared with BFA alone.
