The Nematocyst: a molecular map of the Cnidarian stinging organelle
International Journal of Developmental Biology, 2012 Nematocysts or cnidocysts represent the common feature of all cnidarians. They are large organelles produced from the Golgi apparatus as a secretory product within a specialized cell, the nematocyte or cnidocyte.

A Study of Nematocyst Discharge of Physalia physalis and Venom Composition
Biology and Life Sciences Forum, 2023 In this work, we studied the effects of various chemicals on P. physalis nematocyst discharge and the composition of the released venom. The exposure of nematocyst to K+ and Na+ induced a massive discharge in a short time of exposure. Conversely, the Ca2+

A quantitative method for maceration of hydra tissue [PDF]
, 1973 A method is described for the maceration (dissociation) of hydra tissue into single cells. The cells have characteristic morphology such that all basic types — epithelial, gland, mucous, interstitial, nematoblast, and nerve — can be distinguished ...

Mini-Collagens in Hydra Nematocytes [PDF]
, 1991 We have isolated and characterized four collagen-related c-DNA clones (N-COL 1, N-COL 2, N-COL 3, N-COL 4) that are highly expressed in developing nematocytes in hydra.

Parasitology, 2020 Myxozoans are parasitic, microscopic cnidarians that have retained the phylum-characteristic stinging capsules called nematocysts. Free-living cnidarians, like jellyfish and corals, utilize nematocysts for feeding and defence, with discharge powered by ...

A molecular filter for the cnidarian stinging response
eLife, 2020 All animals detect and integrate diverse environmental signals to mediate behavior. Cnidarians, including jellyfish and sea anemones, both detect and capture prey using stinging cells called nematocytes which fire a venom-covered barb via an unknown ...

The cnidarian parasite Ceratonova shasta utilizes inherited and recruited venom-like compounds during infection [PDF]
PeerJ, 2021 Background Cnidarians are the most ancient venomous organisms. They store a cocktail of venom proteins inside unique stinging organelles called nematocysts.
