Light modulated cnidocyte discharge predates the origins of eyes in Cnidaria [PDF]
Ecology and Evolution, 2021 Complex biological traits often originate by integrating previously separate parts, but the organismal functions of these precursors are challenging to infer.

Cnidocyte discharge is regulated by light and opsin-mediated phototransduction [PDF]
BMC Biology, 2012 Background Cnidocytes, the eponymous cell type of the Cnidaria, facilitate both sensory and secretory functions and are among the most complex animal cell types known.

Functional analysis in a model sea anemone reveals phylogenetic complexity and a role in cnidocyte discharge of DEG/ENaC ion channels [PDF]
Communications Biology, 2023 Phylogenetic analyses demonstrate a remarkable variety of the degenerin/epithelial Na+ channel (DEG/ENaC) superfamily in Cnidaria and discern an unexpected role for a proton-sensitive DEG/ENaC in N. vectensis cnidocyte discharge.

Doublecortin-like kinase is required for cnidocyte development in Nematostella vectensis [PDF]
Neural DevelopmentThe complex morphology of neurons requires precise control of their microtubule cytoskeleton. This is achieved by microtubule-associated proteins (MAPs) that regulate the assembly and stability of microtubules, and transport of molecules and vesicles ...

PaxA, but not PaxC, is required for cnidocyte development in the sea anemone Nematostella vectensis [PDF]
EvoDevo, 2017 Background Pax genes are a family of conserved transcription factors that regulate many aspects of developmental morphogenesis, notably the development of ectodermal sensory structures including eyes.

Mechanisms of cnidocyte development in the moon jellyfish Aurelia. [PDF]
Evol Dev, 2019 Stinging cells called cnidocytes are a defining trait of the cnidarians (sea anemones, corals, jellyfish, and their relatives). In hydrozoan cnidarians such as Hydra, cnidocytes develop from interstitial stem cells set aside in the ectoderm.

Cnidarian hair cell development illuminates an ancient role for the class IV POU transcription factor in defining mechanoreceptor identity [PDF]
eLife, 2021 Although specialized mechanosensory cells are found across animal phylogeny, early evolutionary histories of mechanoreceptor development remain enigmatic. Cnidaria (e.g.

Epigenomic and transcriptomic analyses reveal cnidocyte specialization in a sea anemone [PDF]
bioRxivAbstract Cnidarians, including corals, hydras, jellyfish, and sea anemones, possess specialized stinging cells called cnidocytes that function in prey capture and defense. These cells represent a striking evolutionary innovation and produce distinct types of organelles such as venom injecting nematocysts and mechanically entangling ...

Cell type-specific expression profiling unravels the development and evolution of stinging cells in sea anemone [PDF]
BMC Biology, 2018 Background Cnidocytes are specialized cells that define the phylum Cnidaria. They possess an “explosive” organelle called cnidocyst that is important for prey capture and anti-predator defense.
