3D Infect – 2nd DFG GRK 2157 Retreat

The graduate college 3D Infect met for two days in Rothenburg ob der Tauber.
Annual Meeting Graduate College 3D Infect Würzburg University

All the participating research teams of the DFG research training group 3D Infect joined for the second annual retreat. Graduate students and principal investigators of the graduate college actively participated to present and discuss the recent progress of the individual projects within the research training group. This vivid exchange and further input from visiting faculty, this year especially on pulmonary host-pathogen interactions, provided a fruitful basis to foster collaborations between the members of the RTG 3D Infect. One such collaborative project authored by the PhD student Sarah Schuster and members of the Engstler and Beilhack labs resulted already in a first joint-publication, which recently appeared in the distinguished journal eLife.

9th Workshop for Experimental Blood and Marrow Transplantation

This year’s Workshop for Experimental Blood and Marrow Transplantation took place in Schweinfurt, a town on the river Main near Würzburg.

9th Workshop for Experimental Blood and Marrow Transplantation, Schweinfurt 2017, GvHD research, immunotherapy, inflammationFrom September 19th to 20th, 2017 cellular immunotherapy, graft-versus-host disease and inflammation, tumor immunology and immune responses against infections were in the focus of 20 research lectures and seven poster presentations by young scientists from four different universities. This year’s meeting was hosted by the Beilhack lab.  Three other active research groups joined from the Charité Berlin, and the Universities of Frankfurt and Freiburg. The Interdisciplinary Center for Clinical Research (IZKF) Würzburg generously supported this interdisciplinary young investigator meeting. Originally, this workshop had been inspired by the annual Stanford immunology retreats in Asilomar, California, which were always highlights for Robert Zeiser and Andreas Beilhack during their postdoctoral training at Stanford University. After returning to Europe the Zeiser and Beilhack labs initiated an annual two-day scientific workshop together with the young research labs of Evelyn Ullrich and Olaf Penack: Once a year these four research teams meet to discuss recent research progress and new perspectives in the field of hematopoietic cell transplantation and immunotherapy. Beside an intense scientific program there was also time for a brief visit to the Georg Schäfer Museum to enjoy Central European art from the 19th century. Already we are looking forward to our 10th workshop, which will be held near Frankfurt am Main in 2018.

Cytotoxic control – New publication in Nature Communications

A long-standing collaboration with Prof. Edgar Serfling that was initiated in the Transregio SFB TRR52 reseach consortium comes now to fruition. Today, these research findings are being published in the prestigious journal Nature Communications.

Cytotoxic T lymphocytes are effector CD8+ T cells that very efficiently eradicate infected and malignant cells. Our new research publication by Stefan Klein-Hessling and colleagues demonstrates that the transcription factor NFATc1 controls the cytotoxicity of mouse cytotoxic T lymphocytes. Activated cytotoxic T lymphocytes, which were deficient for Nfatc1, were also defective to organize their cytoskeleton and to recruit cytosolic organelles to immunological synapses. If CD8+ T cells lacked NFATc1, their cytotoxic potential against malignant multiple myeloma cells dramatically declined. Furthermore, mice with NFATc1-deficient T cells could not control Listeria infections.

Extensive transcriptome analysis revealed that NFATc1 controls multiple programs in cytotoxic T cells including the production of cytokines, chemokines and metabolic programs. This new comprehensive study highlights that NFATc1 is an important regulator of cytotoxic T lymphocyte effector functions.

New paper in eLIFE – In a fly’s gut

New microscopy paper in eLife, Markus Engstler, light sheet fluorescence microscopy, Beilhack lab, LSFM, Würzburg, Germany

Tsetse flies transmit African trypanosomiasis, known as sleeping sickness that causes death months or years after infection. More than 70 million people in sub-Saharan Africa are at risk of this disease.

The cause of these devastating infections are the protozoa of the species Trypanosoma brucei, which is the research focus of the group of Prof. Markus Engstler at the Biocenter at Würzburg University. Thanks to the recently founded DFG graduate college “3D Infect” our research teams connected and studied the week-long journey of Trypanosoma brucei through the different microenvironments of the tsetse fly´s interior organs with advanced microscopy techniques. Dynamic high resolution microscopy revealed the enormous versatility of the incessantly swimming trypanosomes, which cross various barriers and confined surroundings. These rapidly adaptive processes concur with major changes of parasite cell architecture. The new findings by Sarah Schuster et al. about these highly adaptable host-pathogen interactions are now published in the distinguished journal eLIFE.

Lab retreat – Canoeing on the river Main

This year’s lab retreat took us 20km down the river Main from Frickenhausen to Würzburg City. 

On a stunningly beautiful summer day and removed from the research benches our team reconnected for a canoe tour on the picturesque river Main, embedded between vineyards, old Franconian towns and famous wine villages. We enjoyed the nature of the river, refreshing water and good conversations before finally reaching our destination at Würzburg’s city beach – happy and – for some of us – sore muscles guaranteed.

 

New Nature Communications Paper

Nature Communications, Immunology & Imaging Program, Würzburg UniversityToday Nature Communications published a new imaging paper on the physiologic regulation of megakaryocytes within the bone marrow microenvironment. 

Hematopoietic stem cells do not only give rise to our body’s immune system but also to megakaryocytes. These giant cells reside in the bone marrow and produce blood platelets required for hemostasis and thrombosis.

In a collaboration project with research groups of the Rudolf Virchow Center and University of Würzburg and Charité Berlin we unravel the spatial organization of megakaryocytes to efficiently sustain the production of blood platelets. Combining different experimental strategies, including light sheet fluorescence microscopy (LSFM), dynamic 2-photon microscopy (2PM) and computer modeling helped to systematically investigate megakaryocyte migration and function within their natural environment.

Our long-standing collaboration partners, Dr. David Stegner and Prof. Katrin Heinze, led this strongly interdisciplinary research project. The new data support a model of spatial megakaryocyte organization to warrant effective platelet production. These novel findings challenge the current thrombopoiesis model of megakaryocyte migration and, instead, support a modified model: Sinusoidal precursors replenish megakaryocytes at sinusoids rather than cells from a distant periostic niche. These findings imply that megakaryocytes, which apparently do not require to migrate in order to reach bone marrow blood vessels, should be just increased by numbers to raise platelet counts in patients.

Immunology Retreat at Kloster Schöntal

Immunology Training Network Erlangen, Tübingen and Würzburg

The Annual Meeting of the immunology graduate programs from three universities convened for the 12th time
Schönthal Graduate Colleges Retreat 2017 - Good-bye present to Prof. Hünig

Laudatio for Prof. Thomas Hünig (right), founding father of the graduate college Immunomodulation, by Prof. Hans-Martin-Jäck from Erlangen University

Once a year the PhD students of the graduate program Immunomodulation at Würzburg University are responsible for the independent organization of a Mini-Symposium together with fellow students from Erlangen and Tübingen Universities. This year’s meeting from May 29-31, 2017 took place in the pristine place Kloster Schöntal, one hour South of Würzburg. The Beilhack lab contributed to the scientific program three oral presentations and two scientific posters. Julia Hartweg, Katja Ottmüller and Tim Steinfatt were selected for talks to present and discuss their research progress. Musga Qureischi and Haroon Shaikh presented their research projects at the poster sessions. As a highlight of the meeting, Prof. Hans-Martin Jäck and Prof. Hans-Georg Rammensee honored the manifold scientific achievements of Prof. Thomas Hünig. On top of his stellar scientific career, Prof. Hünig also founded the graduate program Immunomodulation at Würzburg University.

Over the years the annual meeting of the immunology graduate programs has proven highly attractive for scholars, supervisors and guests alike because it can be organized as an exciting, joint undertaking with other graduate colleges working on associated topics. For more than a decade the three-day annual meeting has been organized together with the Graduate Colleges Immunomodulation of Würzburg University, Immunotherapy of Tübigen University and Adaptive Immunity of Erlangen University. The scientific program comprises short presentations of the own work of the scholars in form of oral presentations and a multi-poster session. The preferred venues were solitary conference centres (such as Kloster Banz, Kloster Schöntal or Kloster Neresheim) in beautiful surroundings to encourage the communication between supervisors, guests and the students of the different graduate colleges. Also at this year’s meeting the atmosphere was extremely beneficial for the scholars and the lecturers and enabled close interactions between all participants.
