Inhibition of Nematocyst Discharge from Pelagia noctiluca (Cnidaria: Scyphozoa)—Prevention Measures against Jellyfish Stings [PDF]
Marine Drugs, 2022 Pelagia noctiluca stings are common in Mediterranean coastal areas and, although the venom is non-lethal, they are painful. Due to its high toxicity and abundance, P.

A small molecule screen identifies novel inhibitors of mechanosensory nematocyst discharge in Hydra [PDF]
Scientific Reports, 2021 Cnidarians are characterized by the possession of stinging organelles, called nematocysts, which they use for prey capture and defense. Nematocyst discharge is controlled by a mechanosensory apparatus with analogies to vertebrate hair cells.

A Study of Nematocyst Discharge of Physalia physalis and Venom Composition [PDF]
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+

Quantitative Insights into the Contribution of Nematocysts to the Adaptive Success of Cnidarians Based on Proteomic Analysis [PDF]
Biology, 2022 Nematocysts are secretory organelles in cnidarians that play important roles in predation, defense, locomotion, and host invasion. However, the extent to which nematocysts contribute to adaptation and the mechanisms underlying nematocyst evolution are ...

Venom system variation and the division of labor in the colonial hydrozoan Hydractinia symbiolongicarpus [PDF]
Toxicon: X, 2022 Cnidarians (jellyfish, hydroids, sea anemones, and corals) possess a unique method for venom production, maintenance, and deployment through a decentralized system composed of different types of venom-filled stinging structures called nematocysts.
