DEFENDER partner spotlight: the Maisner lab: At the Institute of Virology in Marburg, the Maisner Lab is dedicated to advancing our understanding of the cell biology of highly pathogenic Nipah virus.

DEFENDER partner spotlight: the Steinmann lab The Steinmann lab in the Molecular and Medical Virology (MMV) department at @ruhr-uni-bochum.de primarily focuses on the interplay between viruses and host cells, with particular emphasis on understanding the cell entry mechanisms of various viruses.

DEFENDER partner spotlight: the Aguzzi-lab: The Aguzzi lab is located at the Institute for the Science of the Aging Brain (#ISAB) in St. Gallen.

Great DEFENDER Seminar today with two highly engaging and insightful talks! Birthe Ehlert presented their approach to a comprehensive genome-wide CRISPR screen on HEV, providing valuable insights and takeaways that will be highly relevant for many of the other DEFENDER screening efforts.

Partner spotlight: the @pfaenderlab.bsky.social-lab: Our group at the @leibnizliv.bsky.social focuses on understanding how emerging viruses interact with host cells by using advanced cellular model systems, including three-dimensional organoids that better reflect the complexity of native tissues.

The DEFENDER Seminar took place yesterday again, featuring two excellent talks from Victoria Taylor (on the establishment and optimization of a DENV CRISPR screen) 🦟🦠 and Suman Khan (on the characterization of NiV entry using cryo-EM) 🔬 It’s great to see these projects progressing. Keep it up! 🚀

Great news from the DEFENDER network 👏 Congrats to our coordinator and @leibnizliv.bsky.social PI Stephanie Pfänder @pfaenderlab.bsky.social on her official start as W3 Professor this month at the @uni-hamburg.de, supported by the @leibniz-gemeinschaft.de Programme for Women Professors.

✨ The moment has arrived! ✨ Prof. Dr. Stephanie Pfänder officially starts her W3 Professorship at @uni-hamburg.de today – supported by the Leibniz Professorship Program of @leibniz-gemeinschaft.de. 🔗https://leibniz-liv.pulse.ly/3hj5ndxht0 #UniverstätHamburg #LeibnizProfessorinnenprogramm

Yesterday we hosted the second session of the DEFENDER PhD/Postdoc Seminar Series... and it was a fantastic dive into cutting-edge screening science 🚀 We had two great talks: 👉 Quality control and analysis of arrayed CRISPR screen results by Adriano Aguzzi.

February 11 marks the *International Day of Women and Girls in Science*, highlighting the importance of equal participation in STEM. 🔬 🦠

Congratulations to Alex from the DEFENDER consortium on receiving funding for her research on Nipah virus infection. Her research sheds critical light on how this highly dangerous virus enters the CNS, spreads, and shapes immune responses using advanced cell and tissue models.

Alexandra Kupke@alexkupke.bsky.social · 6mo ago

Honoured and thankful to the Von Behring-Röntgen-Stiftung for funding our work on CNS pathology and the innate immune response following Nipah virus infection 🧠🦠 www.linkedin.com/posts/alexan...

Recent reports from West Bengal remind us why Nipah virus research and surveillance cannot be reactive, it has to be continuous.

First session of the DEFENDER-internal PhD/Postdoc Seminar Series yesterday!! Awesome talks by DEFENDER postdocs Wing Hang Ip and George Ssebyatika. Exciting science, exciting times ahead! 🚀

Season’s Greetings from DEFENDER ❄️🕯️🎄 Wishing you a restful, calm, and cozy holiday season and a strong, healthy, and inspiring 2026 ahead!

Last week, our symposium wrapped up with a DEFENDER-internal program on day 2 at the @leibnizliv.bsky.social! 💪 It was fantastic connecting in person with so many brilliant minds — discussing ongoing projects, exploring new collabs, and sharing ideas that move our consortium forward. #FundedByEU

What an incredible experience at DEFENDER 2025: International Symposium — huge thanks to all participants for the inspiring discussions and great energy! 💡 We loved exchanging ideas on emerging viruses, new methods & cutting-edge research.

Today’s the day! 🎉 We’re looking forward to the DEFENDER 2025: International Symposium in Hamburg, bringing together experts to foster international scientific exchange, strategic project planning, and interdisciplinary networking across virology, immunology, and related fields.

🌍 Join us at the @defender-project.bsky.social International Symposium for a keynote by our #combineMARV coordinator @christian-7.bsky.social! 🎟️ Register free of charge for a day of insights, collaboration & global exchange 🔗 lnkd.in/eY9JwzXY #PandemicPreparedness #Collaboration #EUfunded

👏 Featuring @alexkupke.bsky.social at the Philipp University of Marburg. We’re excited to highlight Alex Kupke, a DEFENDER partner based at the Institute of Virology at Philipp University of Marburg. Her research plays a vital role in advancing our understanding of high-consequence viral threats.

🚀 Introducing Andrea Maisner Andrea is a renowned virologist whose research is at the forefront of understanding Nipah virus — a highly pathogenic zoonotic paramyxovirus with no approved vaccines or treatments.

🚀 Meet @lisa-oestereich.bsky.social Lisa is a leading virologist based at the BNITM in Hamburg, Germany. Her research focuses on some of the world’s most dangerous viruses — including Lassa, Ebola, and Crimean-Congo hemorrhagic fever viruses.
