`Notably, sleep deprivation, ultraviolet radiation, and mutagens increased neuronal DNA damage and sleep pressure, while spontaneous and induced sleep facilitated genome stability in both the diurnal and crepuscular cnidarians. These results suggest that DNA damage and cellular stress in simple nerve nets may have driven the evolution of sleep.`

`By generating localized Chordin sources in the Chordin morphant background, we showed that mobile Chordin is necessary and sufficient to establish a peak of BMP signaling opposite to Chordin source. These results provide evidence for BMP shuttling in a bilaterally symmetric cnidarian and suggest that BMP shuttling may have been functional in the potentially bilaterally symmetric cnidarian-bilaterian ancestor.`

WARNING look away if you don't like stinging things... Physalia, or the bluebottle, a fairly common sight on beaches after a strong wind has blown them ashore. They're not a single organism, but a #community of cooperating zoöids. #JuneSea #photography #macro #cnidaria #beach #EastCoastKin

#Cnidaria are a very old group of animals in terms of #evolutionary #biology. The last common stem species, which they share with all further derived animals, the Bilateria, was the first to have really differentiated tissue. Solitary species and especially Coral colonies create #speciesrich ecosystems and are sensitive to #globalwarming. Therefore, efforts to achieve greater #climateneutrality are important.

In collaboration with Alison Cole and Ulrich Technau we also mapped the peptidergic #connectome of #Nematostella, by linking peptide-expressing to receptor-expressing cells.
In #Cnidaria, tissues are extensively connected via #neuropeptide signalling.
#neuroscience -
Previously, only one #GPCR with a ligand was known in #cnidaria, the receptor for the #Clytia Maturation-Inducing-Hormone. This receptor was found by Gonzalo Quiroga Artigas and Philipp Bauknecht in our lab, in a collaboration with Evelyn Houliston.

To get a comprehensive list of #neuropeptides, we combined #bioinformatic screening and mass spectrometry in collaboration with Amanda Kieswetter and Liesbet Temmerman at KU Leuven. We found 15 new proneuropeptides and confirmed the endogenous processing (cleavage, amidation etc) of many of them. #Nematostella has at least 33 neuropeptide precursors.

In our new preprint we characterise neuropeptide signalling in the cnidarian #Nematostella.
https://www.biorxiv.org/content/10.1101/2023.07.03.547448v1
Daniel Thiel and Luis Yanez-Guerra screened 64 neuropeptides against 161 G-protein coupled receptors (#GPCR) and found activating peptide ligands for 31 receptors.
