In parallel, we'll be publishing a special issue on Imaging Cell Architecture and Dynamics - you can find out more at: journals.biologists.com/jcs/pages/im... Submission deadline: 1 April 2026 #imaging #microscopy #cellbiology

Great study in @natneuro.nature.com revealing reactive astrocyte-specific enhancers by @margheritazamboni.bsky.social et al (@ellorens.bsky.social, @ki.se) + it brings along a neat AAV to target reactive astrocytes => definitely one tool that we want to try out www.nature.com/articles/s41...

Are you interested in cytoskeleton and looking for a postdoc position? I will be advertising positions in the new year but happy to chat in person if you are attending ASCB @ascbiology.bsky.social in Philadelphia. Just drop me a line.

Introducing mScarlet3-S2: a highly photostable and bright red fluorescent protein. www.nature.com/articles/s41...

Researchers at the Crick, @psich.bsky.social and @esrf.fr have developed a new way to look deeper into brain cell connections by using a particle accelerator and a kind of resin borrowed from the aerospace industry. www.crick.ac.uk/news/2025-11...

Tomorrow we will celebrate the 10th Anniversary of our AMBIO Imaging Facility. I am very much to see a lot of cutting edge microscopy data.

Check out our recent preprint, "Live longitudinal imaging of meningeal cerebrovascular injury and its sequelae in adult zebrafish." lnkd.in/gN7z6th4

Macrophages are super! SoRA (superresolution after optical reassignment) microscopy video of a primary human macrophage transfected with Lifeact-GFP to visualize actin-rich podosomes. Star-like appearance is due to connecting cables linking individual podosomes into a cell-wide superstructure ✨

A fantastic paper by my @hhmijanelia.bsky.social colleague and friend Heejun Choi (who is on the job market!). Another elegant use of the Janelia Fluor dyes for cellular imaging. www.nature.com/articles/s41...

What a gem from @dudinlab.bsky.social @gautamdey.bsky.social @centriolelab.bsky.social in Cell! Expansion microscopy atlas of >200 eukaryotes comparing cytoskeletal architectures revealing structures not seen before. Stunning visualisation! Exactly the kind of transformative cell biology we need.

This study reflects the dedication of a great team over many years. I am sincerely thankful to my co-first author Tom Bickel, to our PI Christian Madry and to all collaborators who brought their expertise and care to this work. Read the full story here: www.science.org/doi/10.1126/...

Microglia are the brain’s most dynamic cells, constantly extending and retracting their processes to monitor the parenchyma and respond to potential danger with inflammatory signaling. Our new study in @ScienceAdvances @science.org explores how these functions are regulated.

Check out our exciting project on sex differences at the BBB #sex_differences #astrocytes #depression Funding: @fwf-at.bsky.social In collaboration with @dibenedetto-lab.bsky.social

Very interesting paper in Science Advances by the Madry lab showing that the chloride channel Clic1 regulates morphodynamics and surveillance of #microglia via ERM proteins. These functions are chloride independent. www.science.org/doi/10.1126/...

#microscopymonday video on a multitalented housekeeper in the #brain: Watch amidst #neurons an #astrocyte. The astrocyte phagocytoses debris but is rather stationary compared to the bypassing #microglia cell. #Neurons thrive around the astrocyte and outgrow neurites.

Register for the Dynamic Cell VI conference, Reading, UK, April 2026! This conference focusses on all aspects of cell dynamics, co-organised by @bscb-official.bsky.social and @biochemsoc.bsky.social with @royalmicrosoc.bsky.social and the Chinese Society for Cell Biology. bit.ly/Dynamic-Cell-VI

This #microscopymonday is a cleaning day. Watch how a #microglia cell mops up and phagozytoses debris and junk in a very messy neuronal co-culture. BTW, it was a proper cleaning job → the neurons made it and formed nice networks Phase contrast imaging started at DIV1. One frame per 20 min.

🎉 Congratulations to Dr. Susanne Wegmann on her joint professorship at DZNE and Charité! Her research focuses on the Tau protein in neurodegenerative diseases - a strong boost for brain research in Berlin! 👉 www.dzne.de/en/news/pres...

Something for a belayed #FluorescentFriday. #actin dynamics in differentiating neuroblastoma cells. 'It's fascinating to observe the dynamics of #actin in growth cones and filopodia, even though it's merely GFP-actin. CSU-W1 SoRa Spinning disk #microscopy performed at the AMBIO facility (Charité).

A new #UExM probe for #Actin! Fun times thinking/developing/testing with @centriolelab.bsky.social & @lreymond.bsky.social ! Congrats to all ! If interested in #UExM, or #HAK-Actin, feel free to reach out ! Soon available at @spirochrome.com #Expansion #Microscopy #ProtistsOnSky

Upcoming 'Advanced Bioimaging' Symposium at 19th of November at the Charité to celebrate the 10th anniversary of our AMBIO imaging facility

Eric Peterman @errricpeterman.bsky.social, Jeffrey Rasmussen @jraslab.bsky.social @uwbiology.bsky.social & colleagues discover that microtubules regulate tissue-level navigation in skin-resident macrophages. journals.biologists.com/jcs/article/... Article: journals.biologists.com/jcs/article/...

Back to the roots, where my personal #actin journey started: the Zoological Institute of the @tu-braunschweig.de. It was great to meet old friends at the Farewell party of my PhD supervisor Martin Rothkegel, who sparked my interest in the #cytoskeleton.

⏰ Reminder: The early bird registration and abstract submission for our 5th Day of Intravital Microscopy close on September 5! Don’t miss your chance to join us in Tübingen on 18–19 Sept. Secure your spot today! 👉 bit.ly/3IOlJtJ

We are featuring David Stephens, a former @jcellsci.bsky.social Editor, as an extraordinary biologist this week. The JCS-David Stephens Prize for the best JCS paper is also named after him. #100biologists

I am looking forward to speak about computational astrocyte models ⭐️🧠

Sometimes it is really cool to have Malaria - as a research subject. Awesome work by the @freddyfrischknecht.bsky.social lab on an atypical Arp2/3 complex and its role in Plasmodium DNA segregation. www.nature.com/articles/s41...

Just great. It seems so that here in Germany every decent sequencing company got swallowed by @eurofinsnl.bsky.social. Everything is way more complicated now. We can just hope that their sequencing service has been improved (we did change to other suppliers back in a day for a reason...).

Awesome malaria study out now in Nature Microbiology: An atypical Arp2/3 complex is required for Plasmodium DNA segregation and malaria transmission By Franziska Hentzschel, Matthias Marti, Freddy Frischknecht & colleagues! @freddyfrischknecht.bsky.social www.nature.com/articles/s41...

The 3rd Berlin Single Molecule Biophysics Course will run from 8th to 12th September at the HU-Berlin, Institute of Biology. Learn about single channels, single molecule TIRF, theory and analysis. Apply by 7th July at [email protected]. Fee waivers and bursaries available. ! Please share widely !

Our review Schiweck et al. on #astrocytes, their morphology, and #cytoskeleton cracked today the mark of 200 citations (according to @researchgate.bsky.social). It is very encouraging to see that it has been useful for so many researchers. www.frontiersin.org/journals/cel...

journals.biologists.com/jcs/article/... "Until I started my PhD, I played guitar in an all-girl punk rock band. We played gigs around Milan, and there are still some videos floating around on YouTube (no, I won't tell you the band name!)" We definitely picked the right JCS 2026 meeting organiser!

Wir starten in den Auswahltag der #Exzellenzcluster. Heute kommt das Expertengremium u. die für Wissenschaft und Forschung zuständigen Minister*innen von Bund und Ländern zusammen. Ab ca. 17 Uhr geben GWK-Vorsitzender Falko Mohrs u. Forschungsministerin Dorothee Bär die Ergebnisse bekannt.

@leicamicrosystems.bsky.social Spinning Disk workshop: Tomorrow at 10.00 am at the Charité CCO, Berlin. Talks on phase separation of #synapse proteins, cell signaling, infection biology, and #actin in neuroprotective membrane trafficking during #TBI

Today, I gave a talk about our work on Computational Models of Astrocytes at the Snapshot seminar hosted by the School of Physiology, Pharmacology and Neuroscience at Bristol University. Thank you for the invitation, @dr-vmosienko.bsky.social!

On May 13th, a @leicamicrosystems.bsky.social Spinning Disk Microscopy workshop will take place at the Charité CCO. I am happy to contribute with a talk on #actin and #membranetrafficking under #TBI conditions. Please join, if you are interested in cool live cell imaging & cell biology.

Looking forward to meet many people of the astrocyte aficionado community next week at the EMBO workshop "Astrocytes: From Molecules to Systems" in Venice. meetings.embo.org/files/poster...

Very happy to share several common protocols used in our lab for the second edition of the book "Astrocytes: Methods and Protocols" @lewisholt.bsky.social @astroantho.bsky.social Thanks @dibenedetto-lab.bsky.social for being a very patient editor! link.springer.com/book/10.1007...

Guten Morgen! Nächste Runde der @dgz.bsky.social Lunchseminare steht an, kommt alle nächste Woche Dienstag mittag:

In the paper, we introduce and characterize a new tool for tracking single vimentin IFs in live cells. After noticing single filaments moving independently within ostensibly tight bundles, we used FIB-SEM to take a closer look at vimentin bundle organization and vimentin-microtubule interactions.

Guten Tag, liebe Community! ☀️ Die Berlin University Alliance ist jetzt auf Bluesky aktiv und teilt Neuigkeiten, Einblicke und Stimmen aus Deutschlands erstem & einzigem #Exzellenzverbund! ✨ Folgt uns, um nichts zu verpassen! Los geht’s! 🚀 #DasOffeneWissenslabor #Wissenschaft #Forschung #Innovation

Postdoc opportunity in Paris with Manuel Thery and Laurent Blanchoin. Their laboratory seeks to determine the rules governing the assembly of cytoskeletal architectures.

This is a really nice feature of one of my favourite journals, the @jcellsci.bsky.social. A tree in an ancient forest is protected by my peer review for this journal. Something positive and mind-lifting in these times where many other things are going downhill. forest.biologists.com/landscape/?i...

please re-post! we are looking for a PhD candidate: www.uniklinik-freiburg.de/en/career/jo...

Autism-like features in a fascinating KO model of "good old" profilin 2, published by Witke et al., Bonn University. I am still amazed by how the deletion of one profilin isoform can turn mouse behaviour upside down. www.frontiersin.org/journals/cel...

If you are keen to jeopardise your precious scientific samples, send them via @fedexeurope.bsky.social. It took them bloody four (4!) days to deliver a package from Munich to Berlin, which is a 6.5 hours drive by car. Next time, we will use the pony express...
