Projects

The scientific research is structurally divided into two project areas:

Project area A: Strengthening GvL effects

Project area B: Prevention and treatment of GvHD.

This division has proven to be successful and constructive. Collaborative activities between the project areas have transformed the TRR 221 into a tight network in which it is clearly recognized that each GvL-modulating strategy must take into account its influence on GvHD (and vice versa). 

What are A-Projects?

Research projects that focus on the amplification of the graft-versus-leukemia (GvL) effect are grouped as A-projects. Briefly, they explore T cell redirection tools (i.e. T cell receptors (TCRs; A01), chimeric antigen receptors (CARs; A02, A03), tri-specific antibodies (A04) for the enhancement of hematopoiesis-restricted GvL activity and examine the reactivation of silenced GvL responses through improved functional and reproductive „fitness“ of donor immune cells. The latter approaches include the amelioration of metabolic stress (A06), the transfer of T memory stem cells (A07) and the co-activation of innate nucleic acid receptor pathways (A08).

Whats is Project B

Prevention and treatment of GvHD by targeting cell signaling and metabolic pathways, by strengthening immune regulatory networks and by modulating GvHD-promoting co- factors The B-projects focus on the investigation of cell signaling and metabolic pathways (B02-04, B12, B14), immune regulatory/suppressive cells and networks in acute and chronic GvHD (B01, B07- B10, B15) and GvHD-promoting co-factors (B11-B13, B15). Based on their pathophysiological findings, they aim to develop and/or advance novel immunomodulatory strategies for effective prophylaxis and therapy of severe GvHD.  

Taken together, the B-projects tackle the GvHD problem from different angles with the aim to jointly develop innovative complementary or synergistic strategies. The coordinated time- and event-driven biopsy program on gut GvHD in Regensburg provides several B-projects with clinical samples and data of patients for research analyses. All PIs have proven unrestricted willingness to share their expertise, models, technologies and reagents with all other investigators. Promising strategies in GvL projects have been evaluated with respect to their influence on GvHD by the cooperating partners (and vice versa) and all participating institutions supported translational studies evolving from the TRR 221 projects (e.g. B01, B07, B10, B13, MAGIC trial).

Whats is Service Project

Information Infrastructure Project (INF), Service Projects (Z), and Integrated Research Training Group (IRTG) The A/B projects have been strongly supported by the newly established INF project (T. Dandekar, E. Holler, B. Kehr, M. Kunz) that provides the data infrastructure backbone, supporting large-scale omics, imaging, and clinical data. The INF PIs have developed a bioinformatics and data management platform, enabling mechanistic insights into GvHD and GvL immune responses and supporting translational and educational activities. Their broad and diverse expert knowledge was invaluable and contributed significantly to several TRR 221 publications (e.g., INF, refs. 1,10,23). As an outstanding INF achievement the clinical data integration system (DIS) BITCARE has been established at all three sites. Indispensable service was also provided by the pathology project Z01 (M. B¸ttner-Herold, M. Evert, A. Rosenwald), that performs the coordinated sampling and processing of human and murine tissues at each site and employs standardized consensus diagnosis and grading of experimental and human GvHD. The latter has been clearly improved by the TRR 221 owned virtual pathology platform and online CaseCentre (Sysmex/HP), that are both used to jointly evaluate digitized GvHD cases across sites. The project leaders conducted a Round Robin test on human colonic GvHD biopsies to ensure harmonization of the diagnostic approach by the involved pathologists (Z01, ref. 1). A variety of tissue-based histochemical, immunohistochemical, ultrastructural and molecular methods were performed as requested by TRR 221 projects (e.g., refs. 6,7). Service project Z02 by P. Hoffmann, T. Winkler, and A. Beilhack supports the A/B-projects by the generation and cross-breeding of numerous genetically modified mouse strains (e.g. loxP flank in Klf6 gene for conditional deleter mice, IL3 & Csf2 knockout mice, and novel split-cre mice for specific deletion of target genes by a combinatorial expression of the cre recombinase) and assists the projects on-site in the performance of complex mouse ASCT experiments and the conduction of sophisticated in vivo and ex vivo imaging studies. To study the role of the intestinal microbiome in ASCT, Z02 utilizes the proprietary germfree (GF) mouse facility in Regensburg and has performed several ASCT experiments investigating the course of GvHD under GF conditions in coop with B07, B03, B09, and B12. Moreover, a central human biomaterial repository supported by Z03 funds collected samples from hematologic neoplasias, which were provided to A/B-projects as required. To advance ASCT, talented early career researchers (ECRs) require training in their specific field as well as in the basic biology and clinical problems of ASCT. For this purpose, PIs M. Edinger, A. Kremer and F. Berberich-Siebelt further developed and strengthened the cross-site IRTG for doctoral students (PhD, MD) and for MDs (Dr. med.). All IRTG students are enrolled in local graduate programs and the IRTG focuses on complementary ASCT training modules detailed in the IRTG chapter. The joined training of doctoral candidates in medicine (Dr. med.) and natural sciences (Dr. rer. nat./PhD) as well as human biology (Dr. rer. biol. hum./Dr. rer. physiol.) has fostered the 14General information interdisciplinary cooperation and exchange of ideas between scientists and physicians to bridge the gap between laboratory and clinical research. During the 2nd FP, TRR 221 project leaders published 139 peer-reviewed publications on TRR specific topics (w/o reviews and clinical studies; only first and last authorships counted), of which 81 publications list project leaders of at least two different TRR projects as authors (evaluation period: 01/2022 to 04/2025; see also Fig. 3, cooperation array). Of these joint publications, 23 include project leaders from two and 9 from three TRR sites, respectively. Many more joint manuscripts are currently submitted for publication or are in preparation. Notably, joint publications (i.e., from at least two different projects) in the 1st FP (evaluation period: 01/2018 to 07/2021) were 74, of which 12 included project leaders from two and 3 from three TRR 221 sites (as detailed in our last proposal). This strong increase of joint cross-site publications from the 1st to 2nd FP clearly demonstrates that the TRR 221 has evolved into a strongly interacting and intensely collaborating research consortium during the first two FPs.

Project A01

Deciphering the role of HLA-DO in immune responses after allogeneic stem cell transplantation.
Site: Erlangen
Principal Investigator: Dr. rer. nat. Hannah Reimann, PD Dr. Dr. med. Anita Kremer, Ph.D.

Induction of the graft-versus-leukemia (GvL) effect in the absence of graft-versus-host disease (GvHD) by CD4+ T-cells directed against DM-sensitive antigens will be tested in murine models of allogeneic bone marrow transplantation both in a minor and a major mismatch setting. Using H2-O (murine HLA-DO) knock-out and transgenic mice as well as wild type mice as recipient strains will allow us to determine the role of the tissue-specific expression of H2-O for induction of GvL effect and GvHD. In addition, we aim to unravel regulation of HLA-DO expression in human cells. Finally, we will test effects of HLA-DO regulators on GvL effect and GvHD.

Project A02

Efficacy and safety of HLA-DPB1-specific T cell receptors as mediators of graft-versus-leukemia effect.
Site: Regensburg
Principal Investigators: Prof. Dr. med. Simone Thomas, Prof. Dr. med. Wolfgang Herr

HLA-DPB1 mismatch antigens occur in allogeneic HSCT from unrelated donors and represent powerful leukemia rejections antigens, which can be efficiently targeted by T cells that have been genetically reprogrammed with allo-HLA-DPB1 specific T-cell receptors (TCR-DP). In this project we will develop an approach that allows for efficient and safe TCR-DP gene therapy in allogeneic HSCT. Special emphasis will be placed on the prevention of treatment-induced HLA-DP-specific alloreactivity to non-hematopoietic tissues (e.g. by „ON-Switch“ TCR or TCR-RNA transfer) and on the development of a novel humanized mouse model that enables the pre-clinical testing of this approach.

Project A03

Advanced CAR T cell engineering to augment the graft-versus-leukemia effect of allogeneic HSCT.
Site: Würzburg
Principal Investigators: Prof. Dr. med. Michael Hudecek, Prof. Dr. med. Hermann Einsele

In this project, we apply the chimeric antigen receptor (CAR) technology to augment the GvL effect of HSCT. CARs are synthetic designer receptors that redirect the specificity of T cells to recognize malignant cells. We will pursue two novel CAR targets, i.e. FLT3 in acute myeloid leukemia and SLAMF7 in multiple myeloma, and apply cutting-edge strategies to increase their efficacy (e.g. through metabolic arming) and safety (e.g. with enhanced suicide genes). To avoid GvHD, we will generate CMV-specific (endogenous TCR) CAR-T cells and employ novel in vivo models to evaluate their ability to concomitantly battle against leukemia/myeloma and CMV infection.

Project A04

Novel tri-specific T-cell activating antibodies for personalized graft-versus-leukemia therapy.
Site: Würzburg
Principal Investigators: Dr. med. Thomas Bumm, Dr. rer. nat. Zeinab Mokhtari, Prof. Dr. med. Gernot Stuhler

We aim to develop novel bi-molecular hemibody constructs that address antigen combinations instead of single target molecules for high precision immunotherapy in the context of allogeneic HSCT. In a first step, we opt to improve the biochemical properties of the constructs focusing on stability, solubility and producibility. In a second step, we will establish humanized NSG mouse models to investigate pharmacokinetics and the specific requisites of dual antigen targeting, mimicking the clinical situation of leukemia patients undergoing allogeneic HSCT.

Project A06

Metabolic stress related immune alterations with impact on graft-versus-leukemia effect in allogeneic stem cell transplantation.
Site: Erlangen
Principal Investigators: Prof. Dr. med. Dimitrios Mougiakakos, Prof. Dr. med. Andreas Mackensen

We hypothesize that oxidative stress confers immunological “hits” that predispose for leukemia relapse. The reconstituting donor immune system, which is fundamental for the GvL effect, is negatively impacted by oxidative stress. Our project addresses the importance of redox-balance after allo-HSCT. We will assess oxidative stress and its impact on immune reconstitution and function in allo-HSCT patients. We will test interventions for improving the T-cells’ anti-oxidative capacities together with other key functional properties. Our goal is to identify novel redox biomarkers predicting relapse risk that will allow us the rational design of targeted redox modulation for relapse prevention.

Project A07 

Enhancing graft-versus-leukemia responses by donor-derived CAR-modified CD8+ T memory stem cells.
Site: Regensburg
Principal Investigator: Dr. med. Dennis Harrer, Prof. Dr. med. Luca Gattinoni

Relapse after alloHSCT is frequently associated with poor survival in patients with advanced B-cell malignancies. In order to investigate curative options for those patients, we are conducting in collaboration with the US National Cancer Institute (NCI) a first in human trial employing donor-derived CD19-CAR TSCMcells. In this project, we plan to perform a comprehensive and detailed immunomonitoring comparing TSCM-enriched CAR T cell products to conventional donor-derived CAR T cells from a prior NCI study conducted on a similar subset of patients. In particular, we will investigate potential benefits of the TSCM cell platform in terms of CAR T cell expansion, long-term persistence, CAR T cell functionality, safety profile and alloreactivity. Finally, by using retroviral insertion and TCR clonotype analyses, we will assess the differentiation trajectory of CD19-CAR and untransduced TSCMcells to determine how CAR signaling affect their self-renewal and multipotency.

Project A08

Timed targeting of cGAS / STING to improve tissue-regeneration and anti-tumor responses following allo-HSCT.
Site: Regensburg
Principal investigator(s): Prof. Dr. med. Hendrik Poeck, Dr. rer. nat. Christian Schmidl, PhD

The impact of selective and timed activation or inhibition of the type I interferon inducing cGAS / STING pathway during the course of allo-HSCT and its influence on the GvL effect as well as donor T cell activation and differentiation remains unknown. Using selective receptor ligands and inhibitors, and a combination of advanced in vivo models of leukemia and lymphoma, allogeneic transplantation models, and next-generation sequencing approaches, we aim to unravel the consequences of timed cGAS/STING activation / inhibition during allo-HSCT.

Project B01

Therapeutic targeting of T-follicular cells in GvHD.
Site: Würzburg, Erlangen
Principal Investigator: apl. Prof. Friederike Berberich-Siebelt, PD Dr. med. Silvia Spörl

Calcineurin inhibitors block NFAT activation and protect patients from graft-versus-host disease during bone marrow transplantation. On the other hand, they exert adverse side effects and interfere with the valuable graft-versus-leukemia effect. In contrast, NFAT deficiency maintains graft-versus-leukemia activity, although still protecting from graft-versus-host disease in mouse models. Therefore, it is planned to evaluate new NFAT inhibitors in vitro, on engineered human skin and in mouse models, as well as to ablate NFAT family members by CRISPR/Cas9 ahead of cell transfer.

Project B02

Targeting of TNFR2 and related molecules to separate GvHD from the GvL effect.
Site: Würzburg
Principal Investigator: Prof. Dr. rer. nat. Harald Wajant

Previously, we demonstrated in mice that targeting of TNFR2 and Fn14 allows GvL effect-sparing inhibition of GvHD by different mechanisms. Now, we will clarify whether co-targeting of TNFR2 and Fn14 yields additive or even synergistic therapeutic activity. To facilitate clinical translation of TNFR2 targeting on Tregs, we will also develop human TNFR2-specific antibody variants with Fcγ-receptor-independent agonistic activity and various IL-2 receptor targeted TNFR2 agonists. These reagents will be tested and evaluated in a variety of in vitro models but also in knockin mice in which the ectodomain of murine TNFR2 has been replaced by the corresponding domain of human TNFR2.

Project B03

Generation, molecular characteristics and effector mechanisms of CSF2+-T-cells in graft-versus-host disease.
Site: Erlangen
Principal Investigator: Prof. Dr. med. Kai Hildner

CSF2+ T cells have been recently described to critically mediate immune-mediated tissue-damage in various autoimmune disease models. Their role within the pathogenesis of GvHD has not been studied yet. Our results indicate that CSF2+ donor T cells critically contribute to intestinal GvHD manifestation suggesting that CSF2 might represent a novel drugable target to limit GvHD. Hence, the overall goal of this research project is to molecularly and functionally define the T cell-extrinsic and -intrinsic signals that drive CSF2+ donor T cell formation and identify the characteristics and effector mechanisms of CSF2+ donor T cells in the immune pathogenesis of GvHD.

Project B04

Aldehyde dehydrogenase 3A2 (ALDH3A2) as a novel regulator of inflammation and fibrotic tissue remodeling in sclerodermatous chronic graft-versus-host-disease.
Site: Erlangen
Principal Investigators: Prof. Dr. med. Jörg Distler, PD Dr. med. Regina Jitschin, PhD

Metabolic deregulation is emerging as a common pathogenic driver of chronic inflammatory as well as fibrosing diseases. We demonstrated in our preliminary resultsthat the expression of ALDH3A2 is deregulated in the skin of cGvHD patients in a TGFb-dependentmanner. Inactivation of ALDH3A2 prevented fibroblast activation, whereas overexpression of ALDH3A2 promoted collagen release and deposition of extracellular matrix. Moreover, inactivation of ALDH3A2 modulated leukocyte infiltration and ameliorated tissue remodelingin the murine cGvHD. With the current project, we aim to study the effects of ALDH3A2 on leukocyteinfiltration and fibroblast activation in experimental cGvHD and to decipher the molecular mechanisms, by which ALDH3A2 regulates inflammation and tissue remodeling in cGvHD.

Project B07

GvHD therapy with in vitro expanded donor regulatory T cells.
Site: Regensburg
Principal Investigators: PD Dr. rer. nat. Petra Hoffmann, Prof. Dr. rer. nat. Michael Rehli, Prof. Dr. med. Matthias Edinger

We previously showed that donor CD4+CD25+Foxp3+ regulatory T cells (Treg) prevent lethal acute GvHD after MHC-mismatched BMT in murine models. We now observed that they also ameliorate ongoing GvHD and the prerequisites for efficacious GvHD therapy are studied in this project. For this purpose, the migration pattern of in vitro expanded donor Treg is examined, their organ-specific T cell receptor (TCR) repertoire selection and their site-specific functional status. Finally, we investigate whether their therapeutic efficacy in GvHD can be enhanced by the overexpression of alloreactive TCRs or tissue-specific homing receptors.

Project B08

Harnessing tissue homeostasis-promoting functions of specialized regulatory T cells in graft-versus-host disease.
Site: Regensburg
Principal Investigator: Prof. Dr. med. Markus Feuerer

Regulatory T cells (Treg) perform two distinct functions: they maintain self-tolerance and support organ homeostasis by differentiation into specialized tissue Treg cells. We aim to harness the tissue-repair, organ-homeostasis promoting function of tissue-resident Treg cells to prevent or treat graft-versus-host disease after allogeneic bone marrow transplantation. In this respect, we study a TH2-biased tissue Treg population that is present in virtually all organs. We will use loss-of-function and gain-of-function experiments to understand how these cells function during GvHD. Finally, we want to translate these findings into the human context.

Based on our recent findings on the spatio-temporal kinetics of graft-versus-host disease (GvHD) pathophysiology we discovered a regulatory myeloid cell population that exerts protective functions during the intestinal GvHD effector phase. Employing preclinical mouse models for GvHD and GvL we will interrogate the identity, mechanism of action, and therapeutic potential of this immune-protective myeloid cell subset to improve allo-HSCT.

Project B10

Dysregulation of the B-lymphocyte compartments leading to chronic GvHD.
Sites: Erlangen & Regensburg
Principal Investigators: Prof. Dr. rer. nat. Thomas Winkler, Dr. med. Julia Winkler, Prof. Dr. med. Daniel Wolff

Although experimental data point to a crucial role of antibody mediated damage in chronic GvHD clinical evidence remains restricted to associations but direct proof is lacking. Within the research program we will analyse clonal B cell subpopulations directly involved in clinical chronic GvHD, characterize host specific antibodies including identification of targets and glycosylation profile, analyse T follicular helper cells mediating this process and finally characterize B cell infiltration host-and donor-antibody mediated damage of target organs.

Project B11

Targeting the reciprocal interaction of GvHD and atherosclerosis after allogeneic HSCT.
Site: Würzburg
Principal Investigators: Prof. Dr. med. Alma Zernecke, Prof. Dr. med. Dr. med. univ. Andreas Beilhack

Patients undergoing allogeneic HSCT have an increased risk of cardiovascular disease. To address the interconnection between GvHD and atherosclerosis, we will use a GvHD-atherosclerosis mouse model and analyze GvHD activity, plaque development, as well as local and systemic immune responses. We will further focus on monocytes/macrophages and CD8+ T cells in mediating vascular inflammation and GvHD using relevant knockout mice and/or cell depletion strategies. In addition, we will investigate the potential of immunosuppressive drugs to improve GvHD-related atherosclerosis. It is our aim to define novel approaches to reduce cardiovascular events after HSCT.

Project B12

Regulation of the immune balance during allogeneic hematopoietic stemm cell transplantation (HSCT) by vitamin D3.
Sites: Regensburg & Erlangen
Principal Investigators: Prof. Dr. rer. nat. Marina Kreutz, PD Dr. rer. nat. Heiko Bruns

To understand the underlying mechanisms for the protective effects of vitamin D3 in allogeneic HSCT patients we will investigate vitamin D3-related changes in the microbiome, epithelial barrier function and immune cell infiltration in GvHD target tissues in murine GvHD models. In vitro-analyses will prove direct effects of vitamin D3 on the function of T cells and macrophages. Results will be confirmed in murine models after selective deletion of the vitamin D receptor in T cells, macrophages and epithelial cells. Finally, effector mechanisms will be verified in human GvHD samples. Results should provide the basis for vitamin D3 supplementation of allo-HSCT patients in a prospective clinical trial.

Project B13

Enterococci in allogeneic stem cell transplantation – indicators of loss of diversity or true GvHD pathogens?
Site: Regensburg
Principal Investigators: PD Dr. med. Daniela Weber, Prof. Dr. med. Dr. rer. nat. André Gessner, Prof. Dr. med. Ernst Holler

Based on our previous observation, that high enterococcal abundance associates with GvHD, we aim to analyze the causal relationship between enterococci and GvHD. Enterococcal strains collected from GvHD patients will be tested for pathogenicity in epithelial cell cultures as well as in murine models of colitis and GvHD: GvHD will be induced after recolonization of mice pretreated with antibiotics or of germfree mice with apathogenic and highly pathogenic strains. Full sequencing and targeted mutagenesis of specific enterococcal strains will be performed to identify strain specific pathogenicity factors.

Project INF

Data integration platform and systems medicine efforts to foster GvL and GvHD research
Site: Regensburg, Erlangen, Würzburg
Principal Investigator: Prof. Dr. med. Thomas Dandekar, Prof. Dr. med. Ernst Holler, Prof. Dr. rer. nat. Birte Kehr, Dr. rer. nat. Meik Kunz

The INF project represents the data infrastructure project. It focuses mainly on data   management and sustained storage of all publication relevant scientific data. We also support the individual projects with adequate software and expert knowledge during the entire data analysis process. Our long-term aim is that the increasing amount of research data generated by the numerous immunologists, physicians and other scientists at the TR 221 sites Regensburg, Erlangen and Würzburg ultimately help to find new ways and tools that make allogeneic hematopoietic stem cell transplantation a more safe and effective treatment procedure, particularly by reducing transplant complications and relapse rates in patients. The INF project is financed during the first funding period by funds from the free state of Bavaria.
