Drastic facilitation by alpha-latrotoxin of bovine chromaffin cell exocytosis without measurable enhancement of Ca2+ entry or [Ca2+]i.
1. Latrotoxin (LTX, 1-3 nM) caused a gradual increase of the spontaneous catecholamine release rate in bovine adrenal chromaffin cells superfused with normal Krebs-Hepes solution containing 2.5 mM Ca2+. Ca2+ removal abolished this effect. LTX enhanced also the secretory responses to high K+ (35 or 7...
