A Ca2+ influx associated with exocytosis is specifically abolished in a Paramecium exocytotic mutant.

The Journal of cell biology - 1 Dec 1990

Kerboeuf D, Cohen J

Abstract excerpt

A Paramecium possesses secretory organelles called trichocysts which are docked beneath the plasma membrane awaiting an external stimulus that triggers their exocytosis. Membrane fusion is the sole event provoked by the stimulation and can therefore be studied per se. Using 3 microM aminoethyl dextran (AED; Plattner, H., H. Matt, H.Kersken, B. Haake, and R. Stürz, 1984. Exp. Cell Res. 151:6-13) as a vital...
