What is your current position?

I am a PhD Student of AG Scholtysek and member of the Transregio CRC 369 “DIONE – Degeneration of Bone due to Inflammation”.

What is your main research focus?

Our lab studies bone metabolism, particularly how antimicrobial peptides (AMPs) affect conditions like osteoporosis, arthritis, and periodontitis. My research zeroes in on Transferrin receptor 2 (Tfr2), a protein that helps regulate iron in the blood. While Tfr2 is well-known for its role in iron balance, recent findings suggest it also impacts cells involved in bone health, like macrophages and osteoclasts. I’m investigating how the absence of Tfr2 leads to iron overload and bone loss, using knockout mice as a model. The specific role of Tfr2 in osteoclasts hasn’t been widely explored yet, but the more we dig, the clearer it becomes that Tfr2 plays a major part in bone metabolism. Understanding this could open new doors for treating osteoporosis and bone fragility linked to iron disorders, which is why I’m focused on Tfr2’s role in osteoclasts.

What does your typical workday look like?

As a PhD student, my days usually start early and revolve around hands-on lab work, analyzing data, or designing the next experiments. Right now, my research focuses on both mouse models and in vitro studies, so I spend a good chunk of time in the lab running assays and making sure everything is on track for the next steps.

Chronic inflammatory diseases occur when the immune system, usually a finely tuned network, overreacts and attacks healthy tissue. Current treatments often rely on immunosuppressive drugs, such as cortisone, which reduce immune activity but also leave the body more vulnerable to infections.

Prof. Andreas Ramming, immunologist and Deputy Director of the Department of Medicine 3 at Uniklinikum Erlangen, is taking a different approach: reactivating the body’s own cellular defense mechanisms to prevent healthy cells from being mistakenly attacked. This strategy offers new hope for conditions like rheumatoid arthritis and spondyloarthropathies, while avoiding the drawbacks of general immunosuppression.

His team was recently awarded the ERC Proof of Concept grant for this innovative strategy, marking an important milestone on the path to the first human trials.

The potential: a new class of targeted therapeutics that could change the way chronic inflammatory diseases are treated, making therapies more precise and safer for patients.

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?

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.
