PaxA, but not PaxC, is required for cnidocyte development in the sea anemone Nematostella vectensis. [PDF]
Evodevo, 2017 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. Nematostella vectensis, the starlet sea anemone, has numerous Pax orthologs, many of which are expressed early during embryogenesis.

Old cell, new trick? Cnidocytes as a model for the evolution of novelty. [PDF]
Integr Comp Biol, 2014 Understanding how new cell types arise is critical for understanding the evolution of organismal complexity. Questions of this nature, however, can be difficult to answer due to the challenge associated with defining the identity of a truly novel cell.

The Electrophysiology of Cnidocytes [PDF]
Journal of Experimental Biology, 1987 ABSTRACT Electrical properties of cnidocytes isolated from the hydroid Cladonema and the scyphomedusa Chrysaora were examined using current- and voltage-clamp recording techniques. The stenoteles of Cladonema produced action potentials when depolarized above 0mV.

Evidence for a Common Pattern of Peptidergic Innervation of Cnidocytes
The Biological Bulletin, 2004 Tentacles from representatives of all four classes of the phylum Cnidaria were examined using antibodies against the neuropeptides FMRFamide and RFamide to reveal the organization of neurons and nerve nets associated with cnidocytes. The tentacles of all species examined contained FMRFamide- or RFamide-immunoreactive neurons, in varying densities.

NF-κB is required for cnidocyte development in the sea anemone Nematostella vectensis
Developmental Biology, 2013 The sea anemone Nematostella vectensis (Nv) is a leading model organism for the phylum Cnidaria, which includes anemones, corals, jellyfishes and hydras. A defining trait across this phylum is the cnidocyte, an ectodermal cell type with a variety of functions including defense, prey capture and environmental sensing.

Preparation and Properties of Cnidocytes from the Sea Anemone Anthopleura elegantissima
The Biological Bulletin, 1988 Cnidocytes were isolated from the tentacles and acrorhagi of Anthopleura elegantissima by enzymatic treatment with papain followed by centrifugation in a Percoll-containing medium to produce a concentrated fraction of these cells. The morphology of the isolated cells, as revealed by light and electron microscopy, showed that these cells had intact ...

Cloning and functional expression of voltage-gated ion channel subunits from cnidocytes of the Portuguese Man O'War Physalia physalis [PDF]
Journal of Experimental Biology, 2006 SUMMARY Cnidocytes were dissociated from the tentacles of the Portuguese Man O'War Physalia physalis using heat treatment, and purified using density centrifugation. Visual observation confirmed that these cnidocytes contained a nucleus, a cnidocyst and an apical stereocilium, confirming that the cells were intact.

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.

A Network Approach to White Band Disease Challenged Staghorn Coral <i>Acropora cervicornis</i>microRNAs and Their Targets. [PDF]
Ecol EvolOur study looks at the association between microRNA expression and disease resistance in Caribbean staghorn corals infected with White Band Disease. We find three microRNAs differentially expressed due to disease resistance with putative targets involved in innate immunity.

Effects of Proline and Glycine on the Cnidocyte Discharge of Hydra magnipapillata [PDF]
, 2015 The sense of taste enables animals to utilize environmental cues to detect favorable foods. Through specialized sensory receptors, Cnidarians employ stinging cells called cnidocytes to perform a variety of activities such as locomotion, capturing prey ...
