Functional Characterization of TRPV-Like Ion Channels Involved in Nematocyst Discharge from the Sea Anemone Diadumene lineata

The Biological Bulletin, 2022
Cnidarians require mechanical stimuli to trigger nematocyst discharge and initiate feeding behaviors. The interval from triggering stimulus to response is tens of microseconds, making it likely that mechanically gated ion channels trigger nematocyst ...

Cloning and functional expression of voltage-gated ion channel subunits from cnidocytes of the Portuguese Man O'War Physalia physalis [PDF]

Journal of Experimental Biology, 2006
SUMMARY Cnidocytes were dissociated from the tentacles of the Portuguese Man O'War Physalia physalis using heat treatment, and purified using density centrifugation. Visual observation confirmed that these cnidocytes contained a nucleus, a cnidocyst and an apical stereocilium, confirming that the cells were intact.

Immunolocalization of a Voltage-Gated Calcium Channel β Subunit in the Tentacles and Cnidocytes of the Portuguese Man-of-War, Physalia physalis

The Biological Bulletin, 2014
This study investigated the localization of a voltage-gated calcium channel (VGCC) β subunit in the tentacles and cnidocytes of the Portuguese man-of-war using confocal immunocytochemistry. An antibody specific to the Ca(2+) channel β subunit of the Portuguese-man-of-war (PpCaVβ) was generated, and characterized by Western immunoblotting.

The evolution of cnidarian stinging cells supports a Precambrian radiation of animal predators

Evolution & Development
Cnidarians—the phylum including sea anemones, corals, jellyfish, and hydroids—are one of the oldest groups of predatory animals. Nearly all cnidarians are carnivores that use stinging cells called cnidocytes to ensnare and/or envenom their prey. However,

The Role of Cnidocytes in Transdermal Drug Delivery: A Systematic Review

Cnidaria is a water-dwelling phylum characterized by a cnidocyte stinging cell. In nature, cnidocytes are used to immobilize or “sting” prey, for defense, and for locomotion, but their mechanisms also hold implications for drug delivery. Oral drug delivery has limitations that warrant new drug delivery techniques. One prominent method, transdermal drug
