PK11195
a ligand of peripheral-type benzodiazepine receptor can stimulate thealdosterone secretion of isolated adrenal glomerulosa cell: this effect could be abolished by nifedipinewhich mainly blocks the calcium channel in plasma membrane
but could not be abolished bydantrolene
a selective blocker of mitochondria calcium channel. Even under the condition of themaximum stimulative effects on aldosterone secretion
PK11195 could not change the cyclic AMP(cAMP) content in isolated glomerulosa cells. These results indicated that in the modulatory mecha-nism of benzodiazepine receptor on aldosterone secretion
the intracellular messenger might be theCa
2+
from extracellular Ca
2+
pool
but not the Ca
2+
from mitochondria Ca
2+
pool or cAMP.
