Cnidocyte Supporting Cell Complexes Regulate Nematocyst-Mediated Feeding Behaviors in the Sea Anemone Diadumene lineata

The Biological Bulletin, 2020
Cnidarians, as model animals for studying conserved feeding behavior, possess the simplest nervous and digestive systems. Feeding behavior in cnidarians begins with nematocyst-mediated prey retention, proceeds to coordinated tentacle movements and mouth ...

BK Channels Function in Nematocyst Discharge from Vibration-Sensitive Cnidocyte Supporting Cell Complexes of the Sea Anemone Diadumene lineata

The Biological Bulletin, 2023
Integrated chemo- and mechanosensory pathways, along with activated calcium influxes, regulate nematocyst discharge from sea anemone tentacles. Discharge from vibration-sensitive Type A cnidocyte supporting cell complexes use calcium-conducting transient

Cnidocyte mechanoreceptors are tuned to the movements of swimming prey by chemoreceptors.

Science, 1989
Cnidocytes, the stinging cells of cnidarians, discharge nematocysts in response to physical contact accompanied by the stimulation of specific chemoreceptors.

The cnidarian cnidocyte, a hightech cellular weaponry

BioEssays, 1995
The members of the phylum Cnidaria (corals, sea anemones, medusae) are all equipped with stinging cells (cnidocytes, nematocytes), which serve mainly in prey capture and defense.

The regulation of cnidocyte discharge.

Toxicon, 2009
Because cnidocytes are exceedingly complex cells which can only be used once, their discharge is highly regulated by way of a variety of chemosensory, mechanosensory and endogenous pathways. The integration of these various inputs ultimately results in exocytosis and then discharge of the cnidocyte's diagnostic organelle, the cnidocyst.

Conserved and lineage-restricted gene regulatory programs modulate developmental cnidocyte specification in Nematostella vectensis

bioRxiv
AbstractCnidocytes are a synapomorphy of cnidarians that have evolved a range of morphologies and functions within and across extant species, which makes them an excellent model to investigate how novel cell types emerge and radiate in evolution. One way to gain insight into how cell types evolve is to investigate the gene regulatory networks (GRNs ...
