At the 50th European Congress of the European Society for Blood and Marrow Transplantation (EBMT) in Glasgow, Dr. Haroon Shaikh was honored with the prestigious EBMT Basic Science Award 2024. Representing the Beilhack lab at the University Hospital Würzburg and our DFG TRR221 GvH-GvL consortium Erlangen-Regenburg-Würzburg, Dr. Shaikh uncovered that blood vessel cells in lymph nodes activate alloreactive CD4+ T cells, thereby initiating acute GvHD.

This discovery offers new avenues for treating patients post-allogeneic stem cell transplantation. “A series of rigorous experiments revealed that endothelial cells in lymph node blood vessels can trigger the dangerous immune response,” explained Dr. Shaikh. “These findings present several new therapeutic strategies to enhance leukemia patient outcomes.”

Dr. Shaikh’s award-winning research, titled “Lymph Node Blood Endothelial Cells Prime Alloreactive CD4+ T Cells in Acute Graft-Versus-Host Disease Initiation,” was recognized for its outstanding contribution at the EBMT Congress. Alongside the Basic Science Award, Dr. Shaikh also earned the Young Investigator Award, while his colleague Juan Gamboa Vargas, also from the Beilhack lab received a Best Young Abstract Poster Award.

“These accolades underscore the vital importance of basic research in preclinical models and patient sample analysis for enhancing current therapies and devising entirely new treatment strategies,” said Prof. Beilhack. “The Basic Science Award is especially motivating for our team, and it is an invaluable boost for Dr. Shaikh as he embarks on establishing his own research group.”

Prof. Hermann Einsele, Director of the Department of Medicine II, and speaker at Würzburg University Hospital for the DFG-funded Collaborative Research Center Transregio 221 “GvH-GvL,” commented: “Being awarded this prestigious European research prize for the second time in three years validates that we are on the right path to significantly advancing cancer immunotherapy.”Haroon Shaikh from the Beilhack lab receives the EBMT Basic Science Award 2024

Building on the new discovery, the research team plans to pursue three new directions based on these findings: examining similar blood vessel cells in the bone marrow for targeted immune responses against cancer, investigating whether lymph node endothelial cells also present antigens from surrounding organs to alloreactive T cells, and exploring strategies to alter antigen presentation by lymph node blood vessels to prevent acute GvHD in patients.

Decoding Two-Way Brain-Gut Communication Unveils New Insights into Neurological Diseases

Cells move from the brain to the gut and back. – A new paper by Rhonda McFleder et al. reveals a groundbreaking discovery in the intricate world of brain-gut communication. Published in “Nature Communications,” the study challenges the conventional wisdom that communication between the brain and the gut is a one-way street.

“In our latest study, we demonstrate that brain-to-gut communication is a dynamic two-way process. Cells can migrate from the brain to the gut, influencing the spread of diseases,” explains neurobiologist Professor Rhonda McFleder, who lead the study alongside Professor Chi Wang Ip.

The research focuses on the role of immune cells, particularly macrophages, in the progression of Parkinson’s disease. The team discovered that proteins linked to Parkinson’s, specifically α-Synuclein (αSyn), migrate from the brain to the gut, causing disruptions. Notably, these protein accumulations were found in macrophages, not the neurons controlling the gut’s autonomous nervous system.

“To definitively test the migration of macrophages from the brain to the gut, we developed a method to label brain cells and track their migration,” says Rhonda McFleder, who teamed up with the Beilhack lab to uncover a unique communication between the brain and gut, suggesting its involvement in Parkinson’s disease spread.

Professor Chi Wang Ip adds a crucial finding: “We observed that macrophages not only migrate in Parkinson’s but also under control conditions, broadening the relevance to other neurological diseases. Just as these cells drive pathology in Parkinson’s, they may also promote disease spread in other neurological conditions.”

Next steps involve fully characterizing these migrating cells and identifying homing molecules guiding them to the gut. “Once identified, we can develop therapeutics targeting these molecules, potentially halting the progression of Parkinson’s and other neurological diseases,” says Rhonda McFleder.

The study involved collaboration from various research groups and received support from the Alexander von Humboldt Foundation, the Bavarian Ministry of Economic Affairs, the German Research Foundation (DFG), the Interdisciplinary Center for Clinical Research (IZKF) at the University of Würzburg, the VERUM Foundation, and the former EU Horizon 2020 research and innovation program.

Dr. Stefanie Schwinn’s exceptional work has made a significant contribution to the development of potential therapy approaches for children with this highly aggressive brain tumor. Her findings now provide a solid foundation for clinical research and hold the potential to enhance treatment options for this patient group.

Breakthrough in Overcoming Immune Therapy Resistance

A new study published today in Nature Communications uncovers that the cytokine GDF-15 inhibits T cell infiltration into tumors, opening up promising new pathways for cancer therapy. Researchers from Würzburg University Hospital and the biotech spin-off CatalYm have demonstrated that high GDF-15 levels predict resistance to PD-1-based immune checkpoint blockade therapy. Neutralizing GDF-15 in preclinical mouse models of GDF-15-expressing cancers significantly boosted T cell infiltration and enhanced the therapeutic efficacy of immune checkpoint blockade. This discovery offers a promising target for enhancing the efficacy of immunotherapy across various types.

Blocking GDF-15 enables tumor-specific immune cells to overcome a roadblock for attacking cancer cells.

The team lead by our collaboration partner Prof. Jörg Wischhusen, who is also the scientific cofounder of CatalYm, uncovered that GDF-15 disrupts the LFA-1/β2-integrin-mediated adhesion of T cells to endothelial cells, a critical step for T cell extravasation into tumors. This blockage hinders the immune system’s ability to attack cancer cells effectively.

“Our research shows that GDF-15 acts as a gatekeeper, preventing T cells from entering the tumor environment and neutralizing immune therapy’s effectiveness,” said Dr. Markus Haake, former senior scientist in the Wischhusen lab and now Vice President of Pharmacology at CatalYm and lead author of the study. “Neutralizing GDF-15 improves T cell trafficking and enhances therapeutic outcomes in preclinical models.”

In melanoma patients, elevated GDF-15 serum levels strongly correlate with poor response rates to PD-1 inhibitors. Neutralizing GDF-15 not only improved T cell infiltration but also enhanced the success of immune therapies in murine models, suggesting a potential for broader applications.

CatalYm’s antibody Visugromab, designed to neutralize GDF-15, is currently undergoing Phase-2 clinical trials (GDFATHER study), showing promise in improving outcomes for patients unresponsive to current treatments.

“Neutralizing GDF-15 could revolutionize cancer therapy, providing new hope for patients who currently have limited options,” added Prof. Dr. Jörg Wischhusen, senior author of the study. “This breakthrough underscores the critical role of GDF-15 in immune therapy resistance and highlights the potential of GDF-15-targeted therapies in oncology.”

Linoleic Acid Unleashes Potent Antitumor Immunity in CD8+ T Cells

In a new study published in the prestigious journal Cell Metabolism, lead author Theresa Manzo supported by an international research team unveiled key findings that could revolutionize cancer immunotherapy. The study highlights the profound impact of linoleic acid on cytotoxic T cells, showcasing its potential to enhance the effectiveness of antitumor immune responses.

The Beilhack lab explores novel concepts in immunotherapy against cancer, infections and inflammatory diseases. Würzburg University Immunology Program, GermanyRecently it has been recognized that the metabolic state of CD8+ cytotoxic T cells is a key player in the immune response against tumors. Our interdisciplinary team, in this project under the leadership of Theresa Manzo,   discovered that specific lipids, when improperly regulated, can compromise CD8+ T cell mitochondrial integrity, leading to impaired antitumor responses. Notably, the newly published study demonstrates that linoleic acid emerges as a major positive regulator, bolstering CD8+ T cell activity and overcoming metabolic hurdles. By mitigating exhaustion, cytotoxic CD8+ T cells become capable of sustaining potent and prolonged antitumor responses, offering new possibilities for overcoming challenges in cancer treatment.

The study also shed light on the ability of linoleic acid to induce a memory-like phenotype in CD8+ T cells. This transformation equips the cells with superior effector functions, suggesting that linoleic acid treatment could play a crucial role in enhancing the longevity and effectiveness of immune responses against cancer. A deeper exploration into cellular dynamics revealed that linoleic acid treatment enhances the formation of ER-mitochondria contacts. This action promotes calcium (Ca2+) signaling, optimizes mitochondrial energetics, and boosts the effector functions of CD8+ T cells. 

As linoleic acid-instructed CD8+ T cells exhibited superior antitumor potency both in vitro and in vivo, this new study suggests linoleic acid treatment as an enhancer for more effective adoptive cellular immunotherapy against cancer.

New study identifies niches that sustain Tregs

Today, Haroon Shaikh unveils in a new publication in the Journal of Clinical Investigation Insight a critical mechanism by which fibroblastic reticular cells (FRCs) mitigate acute graft-versus-host disease (aGvHD). Our study identifies how FRCs maintain regulatory T cells (Tregs) by providing T cell receptor signals via MHC class II (MHCII) surface molecules to regulate aGvHD, a severe complication following allogeneic hematopoietic cell transplantation (allo-HCT).FRCs provide protective niches for Tregs JCI Insight Haroon Shaikh, Beilhack lab, Immunology and Immunotherapy Immunprogram, Würzburg University Germany TRR221 GvH GvL

Our team investigated the function of MHCII on Ccl19+ FRCs in shaping the donor CD4+ T cell response during aGvHD. We found that mice lacking MHCII expression on these FRCs experienced exacerbated aGvHD, characterized by aberrant CD4+ T cell activation and significantly reduced Treg and invariant NK T (iNKT) cell expansion. This imbalance led to a loss of protection from aGvHD, even when donor Tregs were adoptively transferred.

Interestingly, while FRCs could process and present antigens and upregulate costimulatory receptors, they were not necessary for the initial activation of alloreactive CD4+ T cells. Instead, their critical role was in the maintenance and proliferation of Tregs during the effector phase of aGvHD, highlighting their immunoprotective function.

This discovery underscores the importance of FRCs in creating a supportive niche for Tregs in secondary lymphoid organs (SLOs). By maintaining Tregs through MHCII-mediated interactions, FRCs help regulate alloimmune responses, offering a potential therapeutic target for aGvHD treatment.

Why these new findings matter
Our research results provide new insights into the cellular and molecular interactions that govern immune responses in aGvHD. Understanding the role of FRCs in Treg maintenance opens up possibilities for novel therapeutic strategies, such as targeting FRCs to enhance Treg function and improve patient outcomes after allo-HCT. Our study’s findings pave the way for future exploration into the adoptive transfer of FRCs or direct targeting of these cells to mitigate aGvHD, offering hope for more effective and patient tailored treatments.

The study resulted from the interdisciplinary collaboration of research teams at Würzburg University Hospital and academic partners from Erlangen, Braunschweig in Germany, Lausanne, St. Gallen and Zurich in Switzerland. The work was supported by our German Research Council (DFG) research consortium TRR221 GvH-GvL.

How tissue-specific unconventional T cells shape local immune responses

A pioneering study published in Immunity today reveals how tissue-specific unconventional T cells travel via lymphatic pathways to lymph nodes, where they orchestrate customized immune responses. This breakthrough has profound implications for targeted vaccination and immunotherapy strategies.

Evolutionary forces shape local tissue contexture. Beilhack lab, Immunotherapy for inflammation, cancer and infections, Würzburg Systems Immunology, Germany

Local environments shape specialized immune responses. (A) Darwin’s Gapagos finches revealed how natural selection drives the adaptation of species to their environments. (B) Similarly, unconventional T cells—including invariant natural killer T (iNKT) cells, gamma delta T (γδ-T) cells, and mucosal-associated invariant T (MAIT) cells— adapt to specific peripheral organ microenvironments. As these immune cells migrate from lungs, small intestines, or the skin to the corresponding draining lymph nodes, they execute immune functions precisely adapted to the local tissue requirements.

Unconventional T cells, including invariant natural killer T cells, gamma delta T cells, and mucosal-associated invariant T cells, differ from conventional T cells by engaging in broader immune surveillance and responding to diverse signals, such as stress signals, lipid antigens, or metabolites.

“Our study demonstrates that local forces guide unconventional T cells from tissues to lymph nodes, where they imprint tissue-specific characteristics,” explains our collaboration partner Prof. Wolfgang Kastenmüller, who lead the international research team.” Dendritic cells have long been known to relay information from peripheral tissues to draining lymph nodes, initiating immune responses. However, it’s now evident that dendritic cells are not solely responsible for this crucial flow of information.  Each tissue harbors unique subtypes of unconventional T cells, influencing the composition and function of T cells in nearby lymph nodes.”

This diversity leads to varied immune responses within lymph nodes, where unconventional T cells form interconnected functional units across different T cell receptor-based lineages. These units are crucial for shaping both innate and adaptive immune responses tailored to the specific tissues drained by each lymph node.

Implications for Future Research and Medicine

Understanding how unconventional T cells migrate and function in lymph nodes is pivotal for advancing immunology and medical practice. Leveraging our insights allows scientists to enhance tissue-specific immune responses, paving the way for precision vaccination and immunotherapy approaches with reduced side effects. This progress holds promise for personalized medicine, facilitating more effective treatments that meet individual patient needs while minimizing adverse effects.

This interdisciplinary research project was led by Prof. Wolfgang Kastenmüller at Würzburg’s Institute for Systems Immunology at the Julius-Maximilians-University Würzburg, in collaboration with groups from the Würzburg Helmholtz Institute for RNA-based Infection Research (HIRI), the JMU Institute for Molecular Infection Biology (IMIB), the Centre d’Immunologie de Marseille-Luminy (CIML), and our team at the Department of Medicine II at Würzburg University Hospital. Financial support was provided by IZKF Würzburg, the German Research Foundation (DFG), the European Research Council (ERC), and the Max Planck Society.

JAM-C as a switch for multiple myeloma dissemination

A new study, published by Andreas Brandl and our team in Blood Advances today, reveals that Junctional Adhesion Molecule C (JAM-C) plays a critical role in the progression and dissemination of multiple myeloma (MM), marking a significant advancement in our understanding of this aggressive blood cancer.

Reciprocal regulation of JAM-C and CD138 switches programs in multiple myeloma cells. Brandl A. et al. Blood Advances 2022

In an interdisciplinary approach, senior scientist Andreas Brandl, PhD, and colleagues have discovered that JAM-C specifically marks a subset of MM cells with low or absent CD138 expression (CD138low/neg), distinguishing them within the bone marrow of both human patients and in MM mouse models. Targeting JAM-C in preclinical models showed a promising reduction in MM progression and dissemination, indicating that JAM-C inhibitors could complement existing treatments and offer new therapeutic avenues.

The study uncovered that JAM-C expression on MM cells correlates inversely with CD138, a canonical cell surface receptor associated with plasma cells. This inverse relationship pinpoints a potential mechanism through which MM cells transition between localized growth and widespread dissemination. Upregulation of JAM-C was observed to facilitate the migration and metastasis of MM cells, a crucial step in cancer spread. Blocking JAM-C in a murine model of MM led to a significant reduction in disease severity, MM dissemination and cancer burden.

Lead Researcher Dr. Andreas Brandl states, “Our research shows that targeting JAM-C could be a pivotal strategy in controlling multiple myeloma progression. This could lead to more personalized and effective treatments for patients suffering from this challenging disease.” The scientist proposes that JAM-C could serve as both, a novel diagnostic biomarker and therapeutic target in MM. He envisions the development of treatments that specifically inhibit JAM-C, potentially enhancing patient outcomes when used alongside conventional therapies such as proteasome inhibitors and monoclonal antibodies.

The new findings result from a collaborative effort by scientists within the SPP consortium µbone of the German Research Council (DFG), the FORTITHER research network of the Bayerische Forschungsstiftung, the Interdisciplinary Center for Clinical Research Würzburg, and international research partners.

Multiple Myeloma Treatment through Targeted Treg Depletion

In a landmark study Dr. Julia Dahlhoff published in the journal Leukemia  a groundbreaking approach to combat multiple myeloma (MM). The paper from our team, titled “Transient Regulatory T-Cell Targeting Triggers Immune Control of Multiple Myeloma and Prevents Disease Progression,” uncovers the potential of briefly depleting regulatory T-cells (Tregs) to unleash the body’s own immune system to eradicate this challenging blood cancer.Transient regulatory T-cell targeting triggers immune control of multiple myeloma and prevents disease progression. Julia Dahlhoff, PhD, Andreas Beilhack Lab, Würzburg University Hospital, Germany, Europe, Immunotherapy program targeting regulatory T cells

Multiple myeloma, characterized by the proliferation of malignant plasma cells in the bone marrow, often relapses due to the protective niche created by bone marrow-resident Tregs. The study reveals that Tregs not only cluster around malignant plasma cells but also support their survival and dissemination.

Using two syngeneic immunocompetent murine models, the team under the leadership of Prof. Andreas Beilhack demonstrated that temporary depletion of Tregs in mice with established MM led to a robust immune response, mediated by CD8 T cells and natural killer (NK) cells, resulting in complete and sustained remission of the disease.

“Targeting Tregs disrupts their suppressive grip on the immune system, allowing CD8 T cells and NK cells to attack and eliminate myeloma cells,” said Dr. Dahlhoff. “This short-term intervention effectively prevented MM progression and offers a new therapeutic strategy that minimizes the risk of autoimmunity.”

The study paves the way for developing Treg-targeted therapies, providing a novel avenue for treatment-resistant multiple myeloma.
