Our observation that 5 mM 4-aminopyridine mimicked the caspase inhibiting effects of pituitary adenylate cyclase activating polypeptide indicates that A-type current is involved in apoptosis.

In the presence of tetraethylammonium (TEA) and 4-aminopyridine (4-AP), PACAP reduced a background K (+) current.

PACAP suppressed a transient outward current that was also suppressed by 4-aminopyridine (0.5 mM).

Because pituitary adenylate cyclase-activating polypeptide (PACAP) has been shown to inhibit the apoptotic cascade in the cerebellar cortex during development, we have investigated the effect of PACAP on K (+) currents in cultured cerebellar granule cells using the patch-clamp technique in the whole-cell configuration.
