Meet our Researcher: Mario Zaiss

What is your current position?

I am Professor for Immune Tolerance and Autoimmunity at the Department of Medicine 3 – Rheumatology & Immunology at Friedrich‑Alexander‑University and Universitätsklinikum Erlangen. I also serve as the speaker of the DFG Research Training School “FAIR –  Fine-Tuners of the adaptive Immune System” and co-speaker of the DFG Research Unit “PANDORA – Pathways triggering AutoimmuNity and Defining Onset of early Rheumatoid Arthritis”.

What is your main research focus?

Our research team is interested in the underlying mechanisms of the gut–bone axis, with a focus on effector molecules linking both systems. Beyond serving as energy carriers, dietary metabolites act as direct modulators of immune functions. Since immune responses both require and reshape metabolism, our work explores the interplay between immunology, metabolism, and nutrition, aiming to advance the prevention and resolution of inflammation in autoimmune diseases.

What does your typical workday look like?

A typical workday starts with a good double espresso and involves many stimulating discussions with students and project leaders on diverse scientific questions. As a group leader, I am also responsible for funding, including administrative tasks and grant applications. I also contribute to university committees with a strong focus on sustainability in research.

Meet Our Researcher: Nadine Otterbein

What is your current position?

I am a Dr. rer. nat. candidate in the group of Prof. Mario Zaiss at Medicine 3 – Rheumatology & Immunology at Friedrich‑Alexander‑University and Universitätsklinikum Erlangen. Furthermore, I am part of the Transregio CRC 369 “DIONE – Degeneration of Bone due to Inflammation”.

What is your main research focus?

My main research focus is the gut-bone and the gut-joint axis in rheumatoid arthritis. I’m investigating how (subclinical) inflammatory processes in the gut can foster bone loss and joint inflammation, supported and enabled by endothelial leakiness. By exploring the cells in the different locations of interest, I’m aiming to identify the key players underlying the gut-bone and gut-joint axis.

What does your typical workday look like?

A typical workday does not really exist for me since it depends on experiments. My workdays are a mixture of wet-lab and dry-lab work. I really enjoy that I can do both: working at the lab-bench but also extensively analysing data, e.g. large omics-datasets. Aside, I’m learning new things every day.

Nachhaltigkeit in der Wissenschaft: Zaiss Lab erhält My Green Lab Zertifizierung

As part of TRR369 DIONE, we’re proud to share that the Zaiss Lab at Uniklinikum Erlangen of

has been awarded the My Green Lab Certification – a benchmark for sustainable practices in scientific research environments.

This certification aligns with DIONE’s mission to foster not only cutting-edge immunological research but also responsible science that meets the environmental challenges of our time. The Zaiss Lab scored particularly high in categories like team engagement, equipment efficiency, and waste reduction – with up to 94% achievement rates in core sustainability metrics.

By implementing best practices and involving all team members in the sustainability process, the lab exemplifies how collaborative research infrastructures can become role models for ecological responsibility.

We congratulate the entire team for their outstanding efforts and encourage other labs within our network to follow their lead.

FeDIOSci Award – Apply now!

We are honouring the FeDIOSci Award for the first time this year.

This funding supports innovative project ideas from young scientists at the interface of bone and the immune system at the Erlangen, Dresden, Ulm and Dortmund sites.
It is an opportunity for young scientists to receive financial support to work on an innovative project idea within osteoimmunology. In this way, preliminary data can be obtained that will ideally lead to an own project within the framework of the second funding period of DIONE.

We are looking for project approaches that ideally lead to an expansion of DIONE’s research activities in terms of content, that dare to think outside the box, have future potential and are translationally orientated. This year, one to two ideas will be supported with a one-off grant totalling 8,000 euros for material resources or support for personnel costs.

Applications are open to doctoral candidates and postdoctoral researchers who are employed at one of the universities or research institutions participating in DIONE, whose doctorate is expected to be completed in 2026 or whose doctorate was completed no more than 6 years ago at the time of the call for applications. In accordance with the DFG guidelines for early career researchers, parental leave of two years per child will be taken into account.

Take the opportunity and apply for your own mini-project.

Application deadline: Mai, 15th 2025

New paper published: L-arginine as a booster of bone health?

Could a common amino acid prove to be a potential therapeutic agent for the reduction of arthritis and bone loss?

 

Rheumatoid arthritis (RA) affects millions of people worldwide, causing joint pain and bone loss due to the excessive activity of bone-resorbing cells, known as osteoclasts. The latest research findings indicate that L-arginine, a common amino acid, may play a pivotal role in the inhibition of this destructive process. It was discovered that L-arginine has the capacity to „reprogram“ osteoclasts, effecting a transition in their energy production from a process that is conducive to bone loss to one that is inhibitory. By modifying the cells‘ metabolism, L-arginine effectively reduces osteoclast formation and activity, resulting in reduced bone erosion. This discovery provides a potential avenue for developing new treatments for RA that utilise the properties of this amino acid to protect our bones. Could L-arginine supplements become a simple and effective strategy to combat arthritis and preserve bone health? Our findings suggest that this is a possibility that warrants further investigation.
