The regulation of cnidocyte discharge.
Because cnidocytes are exceedingly complex cells which can only be used once, their discharge is highly regulated by way of a variety of chemosensory, mechanosensory and endogenous pathways. The integration of these various inputs ultimately results in exocytosis and then discharge of the cnidocyte's diagnostic organelle, the cnidocyst. Here we review what is known about the sensory pathways that regulate cnidocytes, the electrical events that manifest in cnidocytes following sensory stimulation and the ionic mechanisms that underlie discharge.
