Non-muscle myosin II drives critical steps of nematocyst morphogenesis [PDF]
iScience, 2023 Summary: Nematocysts are generated by secretion of proteins into a post-Golgi compartment. They consist of a capsule that elongates into a long tube, which is coiled inside the capsule matrix and expelled during its nano-second discharge deployed for ...

Fluid Dynamics of Ballistic Strategies in Nematocyst Firing
Fluids, 2020 Nematocysts are stinging organelles used by members of the phylum Cnidaria (e.g., jellyfish, anemones, hydrozoans) for a variety of important functions including capturing prey and defense. Nematocysts are the fastest-known accelerating structures in the

Length Is Associated with Pain: Jellyfish with Painful Sting Have Longer Nematocyst Tubules than Harmless Jellyfish. [PDF]
PLoS ONE, 2015 A large number of humans are stung by jellyfish all over the world. The stings cause acute pain followed by persistent pain and local inflammation. Harmful jellyfish species typically cause strong pain, whereas harmless jellyfish cause subtle or no pain.

Excitation of Nematocysts [PDF]
Nature, 1942 THERE has in the past been considerable discussion concerning the nature of the stimulus which causes the nematocysts of Cœlenterates to discharge, In some cases, it is quite clear that the mechanical stimulus to the cnidoblast causes an, explosion of the enclosed nematocyst.

Proteome of Hydra Nematocyst [PDF]
Journal of Biological Chemistry, 2012 Stinging cells or nematocytes of jellyfish and other cnidarians represent one of the most poisonous and sophisticated cellular inventions in animal evolution. This ancient cell type is unique in containing a giant secretory vesicle derived from the Golgi apparatus.

Anemonefish use sialic acid metabolism as Trojan horse to avoid giant sea anemone stinging [PDF]
BMC BiologyBackground Anemonefish association with sea anemones is a prime example of mutualistic symbiosis. These fish live inside the sea anemone, benefitting from the protection of its toxic nematocysts, and in return, protect the anemone from its own predators.
