Go and vote for @dianabrychka.bsky.social's stunning image of a brain organoid ! 🤩

A Boa Constrictor brain-derived cell expressing a viral glycoprotein (magenta) and stained for actin (yellow) and DNA (white). #FluorescenceFriday

HFF cells stained for DNA ⚪, intermediate filaments 🟠, microtubules 🔴 and actin 🔵. #FluorescenceFriday #SciArt

For #FluorescenceFriday, a field of individual VSV (rod-shaped, in 🟧) and Deltavirus (dot-shaped, in 🔵) particles imaged by STED (20nm per pixel). We now know that Deltaviruses can package inside particles of other viruses. Can you find any of these dual particles in this field?

🔬✨ Today for #FluorescenceFriday: A close-up of the dorsal part of the first gill arch in a mature zebrafish. The intricate vascular network supporting respiration, visualized using kdrl:mcherry. #Zebrafish #DevBio #Microscopy #Fluorescence #SciArt

Viruses in the forest of the lungs. Human airway epithelia stained for actin 🟢 and SARS-CoV-2 RNA 🟣. #FluorescenceFriday #SciArt

Saw this presented at ECV 2025. Fanastic and thought provoking work! Congrats to @viroscope.bsky.social, @karimaj.bsky.social and coauthors.

With Joe in our lab, we discovered a new mode of how some viral sattelites can spread : A form of viral hitchhiking we termed Viral Trojan Horse ! check our paper on biorXiv : www.biorxiv.org/content/10.1...

⚠️ Discovery of a new mode of viral transmission: Deltaviruses spread through a viral Trojan Horse ! These viral satellites that do not encode their own glycoproteins, are in fact physically encapsulated within their helper virus particles! www.biorxiv.org/content/10.1... A thread 1/14

The beauty and chaos of structure. HFF cells stained for cytoskeletal proteins Actin (⚪), Septin (🟡), Tubulin (🟣) and DNA (🔵). #FluorescenceFriday #SciArt

#ECV #ECV2025 very proud of @viroscope.bsky.social that presented brilliantly his work in our lab “Deltaviruses spread through viral Trojan Horse” at the European Congress of Virology 2025 in Cavtat, Croatia !

A culture of boa constrictor cells expressing a fusogenic viral protein, leading to cell fusion and giant multinucleated cells! Actin is in gold, membranes in white and DNA in blue. #FluorescenceFriday #SciArt

My monocyte, with a fluorescent membrane (EGFP-CAAX 💛), is transmigrating across the brain microvascular endothelium (VE-cadherin 💙) #FluorescenceFriday #SciArt

A human lung cell expressing the antiviral protein MX1. Actin is in cyan, MX1 in orange and DNA in yellow. #FluorescenceFriday #SciArt

My little brain organoid with stained neurons ❤️ and nuclei 🤍 #FluorescenceFriday #SciArt

Micro-rearrangement of DNA and proteins is a highly dynamic process! As shown here with cell nucleus (DNA in gray) expressing a fluorescent protein (orange). 1 image acquired every 2 seconds for 2 minutes. #FluorescenceFriday #SciArt

New cell line = New cell morphologies to explore! This hepatic cell line has fully invested into membrane protrusions! Actin is shown in 🟦 and DNA in 🟧 #FluorescenceFriday #SciArt

One of my favourite images: monocytes 💙 infiltrating a little brain organoid, with post-synaptic protein PSD95 ❤️ and nuclei 🤍 visualized #FluorescenceFriday #SciArt

A Spiky Cell A boa constrictor brain-derived cell stained for membranes (cyan), actin (yellow) and DNA (pink) #FluorescenceFriday #SciArt

I also have a few examples of my own… as a #FirstGen student, I started with a technical training. during my first intership, a postdoc asked me what I wanted to do afterwards and when I said pursuing my studies and do a PhD, the reply was ‘oh, but you’d need to be clever for that… didn’t you know?´

Pass it on. #StandWithUkraine

Proteins can do weird things sometimes...! Anyone else heard of cytoophidia? A cool and understudied cell biology process! In red is a mutant of an antiviral protein, in cyan is an influenza A virus protein and in yellow are cell nuclei. #FluorescenceFriday #SciArt

Primary monocytes (monocytic Occludin is 💙) transmigrating across the brain endothelium (F-actin is 🧡). Nuclei are 🤍 #FluorescenceFriday #SciArt

3 years ago today we witnessed an act of war, shocking us all and changing the world we live in. Over 3 years, we have seen support, people and countries uniting against this abhorrence. Today, USA sided with Russia, refusing the UN's condemnation. This #MicroscopyMonday we #StandWithUkraine

Dark neon vibes from this one..! Actin in orange, microtubules in purple and nucleus in gray. #FluorescenceFriday #SciArt

Hello neurons 💛 in my little brain organoid. Nuclei are 💙 #FluorescenceFriday #SciArt

Happy #ValentinesDay / #FluorescenceFriday everyone!! :)

When you don't know what to post, just post some phalloidin ❤️ staining of a brain organoid. Happy Valentine's and #FluorescenceFriday to you! #SciArt

The beauty behind the infection. Human lung cells infected with influenza A virus (H3N2). Viral Nucleoprotein in cyan, ER exit sites in red and Nuclei in orange. #FluorescenceFriday #SciArt

Obscure shapes of a brain organoid. Neurons 💙 and nuclei 🧡 are shown #FluorescenceFriday #SciArt

Leukocytes 💙 inside and outside of the blood vessels 🧡 of the brain. Nuclei are in 💚 #FluorescenceFriday #SciArt

A Boa Constrictor brain-derived cell stained for Actin ⚪, cell membranes🟣 and DNA 🔵. #FluorescenceFriday #sciart

My little brain organoid with stained neurons ❤️, astrocytes 💙 and nuclei 🤍 #FluorescenceFriday #SciArt

Throwback to an image of a lung cell expressing the antiviral Mx1 protein that won an image of distinction in the Nikon Small World competition in 2022. Nuclei are in orange, microtubules in cyan and Mx1 in green. Taken during my PhD in @carogoujon.bsky.social lab! #FluorescenceFriday #sciart

A monolayer of Boa Constrictor 🐍 cells stained for Actin 🔵 and DNA 🟠 #FluorescenceFriday #sciart

A Boa Constrictor cell issued from a brain-derived culture, with actin in yellow and DNA in pink. Check out those crazy stress fibers! #FluorescenceFriday #sciart

Confocal image or painting?🤔 #FluorescenceFriday

Today for #FluorescenceFriday, a mouse fibroblast stained for membranes 🟠, microtubules 🔵, and DNA 🟡. #sciart

Time to build up my network after switching here 😁 It's the occasion to share one of my older images for #FluorescenceFriday here! The image shows a massive Boa Constrictor cell culture syncytium with cell membranes in gold, microtubules in cyan and nuclei in grey:) #sciart
