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 ...

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.

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.

Localization of Multiple Jellyfish Toxins Shows Specificity for Functionally Distinct Polyps and Nematocyst Types in a Colonial Hydrozoan [PDF]
Toxins, 2023 Hydractinia symbiolongicarpus is a colonial hydrozoan that displays a division of labor through morphologically distinct and functionally specialized polyp types.

The architecture and operating mechanism of a cnidarian stinging organelle [PDF]
Nature Communications, 2022 The venomous stinging cells of jellyfish, anemones, and corals contain an organelle, the nematocyst, which explosively discharges a venom-laden thread.

Proteomic analysis of FACS-enriched whole nematocysts from the colonial hydrozoan Hydractinia symbiolongicarpus [PDF]
Toxicon: XCnidarians possess a cell-based venom system in the form of nematocytes or “stinging cells” that are found across various tissues. The scattered distribution of these venom-containing cells makes isolation difficult, particularly for proteomic studies ...

Movement and storage of nematocysts across development in the nudibranch Berghia stephanieae (Valdés, 2005) [PDF]
Frontiers in Zoology, 2022 Background Intracellular sequestration requires specialized cellular and molecular mechanisms allowing a predator to retain and use specific organelles that once belonged to its prey.

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 ...

A subset of conserved phagocytic genes are likely used for the intracellular theft of cnidarian stinging organelles in nudibranch gastropods [PDF]
EvoDevoBackground Phagocytosis is a universal physiological process in eukaryotes with many important biological functions. In nudibranch gastropods, a novel form of phagocytosis called nematocyst sequestration is specialized for the uptake of venomous stinging
