biorxiv.org/content/10.1101/… Did you know that sponges can move? @FabianRuperti with @savitski_lab and @Prevedel_lab studied sponge movement and found an evolutionary ancient mechanism controlling cellular tension and defense which is also present in our vasculature! A thread 🧵:

Molecular profiling of sponge deflation reveals an ancient relaxant-inflammatory response

A hallmark of animals is the coordination of whole-body movement. Neurons and muscles are central to this, yet coordinated movements also exist in sponges that lack these cell types. Sponges are...

A genome resource for the marine annelid Platynereis dumerilii

The marine annelid Platynereis dumerilii is a model organism used in many research areas including evolution and development, neurobiology, ecology and regeneration. Here we present the genomes of P....

Happy to announce our new preprint on the ancestry of cell adhesion and self-recognition in animals! We used proteomics and structure-based searches to re-examine the Aggregation Factor from the classical sponge mode first studied by Henry Wilson in 1907! doi.org/10.1101/2024.04.19.5…

Sponges lack muscles & neurons. Yet, they move. How? EMBL Heidelberg Arendt Group @wormduty, @savitski_lab, @Prevedel_Lab & others, showed that sponge movement relies on an ancient relaxant-inflammatory response also found in vertebrate vascular systems. embl.org/news/science/ancien…
An oval light blue shape. In the central part, there is a smaller a red object, from which stem many highly branched smaller canals that cover a significant part of the blue surface. The whole sponge image is in placed in a circle. The background around the circle is blue-green.

Our story about relaxing sponges is out today in @CurrentBiology! 🧽 For a concise summary, check out the thread below 👇 cell.com/current-biology/ful…

Molecular profiling of sponge deflation reveals an ancient relaxant-inflammatory response

The evolution of coordinated behavior in early animals is largely obscure. Ruperti et al. uncover that sponge movement is driven by actomyosin stress fiber relaxation, regulated by Akt/NO/PKG/PKA....

The ocean 🌊 in us: The maintenance of laminar flow is essential for both - sponge canal and vertebrate vascular system  Any deviation leads to the activation of this ancient conserved ‘relaxant-inflammatory’ response as a powerful defense reaction 🛡️.
