AbstractIntegrated chemo- and mechanosensory pathways, along with activated calcium influxes, regulate nematocyst discharge from sea anemone tentacles. Discharge from vibration-sensitive Type A cnidocyte supporting cell complexes use calcium-conducting transient receptor potential V4-like channels.

Physalia physalis, the Portuguese man of war, consumes mostly fish and fish larvae. Intracellular recordings from nematocyst‐containing cells (cnidocytes) in small pieces of Physalia tentacle were used to quantify the electrical responses to diluted and filtered fish skin mucus, 1–100 x 10‐6 M amino acids, monosaccharides, and nucleosides, and seawater,

Evidence that polycystins are involved in Hydra cnidocyte discharge
Like other cnidarians, the freshwater organism Hydra is characterized by the possession of cnidocytes (stinging cells). Most cnidocytes are located on hydra tentacles, where they are organized along with sensory cells and ganglion cells into battery complexes.

The cnidarian cnidocyte, a hightech cellular weaponry
AbstractThe members of the phylum Cnidaria (corals, sea anemones, medusae) are all equipped with stinging cells (cnidocytes, nematocytes), which serve mainly in prey capture and defense. The secretory product of these cells is a most complicated extrusome consisting of a cyst containing a tubule and a liquid matrix. Mechanical stimulation of the cell's

Cnidocytes and adjacent supporting cells form receptor-effector complexes in anemone tentacles
Cnidocytes, the stinging cells of enidarians, discharge enidae (intracellular capsules containing eversible tubules) in response to physical contact combined with the stimulation of specific chemoreceptors. These receptors, occurring in at least two classes, bind N-acetylated sugars and certain amino-compounds, respectively (Thorington and Hessinger ...

ABSTRACT Cnidocyte-supporting cell complexes (CSCCs) discharge nematocysts into targets upon coincidental stimulation of specific chemoreceptors and contactsensitive mechanoreceptors. In addition, CSCCs in the tentacles of at least one species of sea anemone discharge nematocysts into targets vibrating at specific frequencies.
