Evidence that polycystins are involved in Hydra cnidocyte discharge

open access: closedInvertebrate Neuroscience, 2017
Like other cnidarians, the freshwater organism Hydra is characterized by the possession of cnidocytes (stinging cells). Most cnidocytes are located on hydra tentacles, where they are organized along with sensory cells and ganglion cells into battery complexes.

Neural pathways and innervation of cnidocytes in tentacles of sea anemones

open access: closedHydrobiologia, 2004
Our previously published studies are here reviewed detailing neuro-cnidocyte synapses, demonstrating putative neurotransmitter substances, and identifying complex neural pathways in sea anemones. Synapses were traced to their contacts on nematocytes and spirocytes by transmission electron microscopy of serial thin sections of tentacles. In five animals,

Cnidocytes as Microscale Synthesis and Delivery Modules [PDF]

open access: closed, 2008
Abstract : As a first step in using nematocysts isolated from Physalia in a drug-delivery patch, we needed to assess the techniques used to yield efficient discharge. A number of pre-discharge and discharge solutions were utilized to determine the best combination, chosen based on literature findings for nematocysts isolated from other species.

Electrical Responses to Water-Soluble Components of Fish Mucus Recorded From the Cnidocytes of a Fish Predator, Physalia Physalis

open access: closedMarine and Freshwater Behaviour and Physiology, 2021
Physalia physalis, the Portuguese man of war, consumes mostly fish and fish larvae. Intracellular recordings from nematocyst‐containing cells (cnidocytes) in small pieces of Physalia tentacle were used to quantify the electrical responses to diluted and filtered fish skin mucus, 1–100 x 10‐6 M amino acids, monosaccharides, and nucleosides, and seawater,

Immunolocalization of a Voltage-Gated Calcium Channel β Subunit in the Tentacles and Cnidocytes of the Portuguese Man-of-War, Physalia physalis

open access: closedThe Biological Bulletin, 2014
This study investigated the localization of a voltage-gated calcium channel (VGCC) β subunit in the tentacles and cnidocytes of the Portuguese man-of-war using confocal immunocytochemistry. An antibody specific to the Ca(2+) channel β subunit of the Portuguese-man-of-war (PpCaVβ) was generated, and characterized by Western immunoblotting.

Gonadal cnidocytes in the cubozoan Tripedalia cystophora Conant, 1897 (Cnidaria: Cubozoa)

open access: closedJournal of Morphology, 2019
AbstractCubozoans have a complex lifecycle in many ways similar to the scyphozoan lifecycle. The sexual reproduction within cubozoans varies between species with one clade having copulation and internal fertilization and the release of planula larvae.

Cnidocytes and adjacent supporting cells form receptor-effector complexes in anemone tentacles

open access: closedTissue and Cell, 1989
Cnidocytes, the stinging cells of enidarians, discharge enidae (intracellular capsules containing eversible tubules) in response to physical contact combined with the stimulation of specific chemoreceptors. These receptors, occurring in at least two classes, bind N-acetylated sugars and certain amino-compounds, respectively (Thorington and Hessinger ...

Chemoreceptor-mediated elongation of stereocilium bundles tunes vibration-sensitive mechanoreceptors on cnidocyte-supporting cell complexes to lower frequencies

open access: closedJournal of Cell Science, 1991
ABSTRACT Cnidocyte-supporting cell complexes (CSCCs) discharge nematocysts into targets upon coincidental stimulation of specific chemoreceptors and contactsensitive mechanoreceptors. In addition, CSCCs in the tentacles of at least one species of sea anemone discharge nematocysts into targets vibrating at specific frequencies.
