Langerhans cell histiocytosis (LCH) is a rare disease that mainly affects small children. It occupies a hybrid position between cancers and inflammatory diseases, which makes it an attractive model for studying cancer development. While LCH can heal itself in some patients, other cases require intensive chemotherapy with long-term consequences for the children. The reasons for […]

A molecular switch to high-revving innate immunity

The interferons initiate a signaling process that causes the cell to activate the protein complex ISGF3 for driving antimicrobial gene expression. Scientists led by Thomas Decker at the Max Perutz Labs now found out that two of the three proteins forming this complex are permanently present at these genes, independently of the activating cascade caused […]

Sebastian Kollmann and Anna Orlova receive the Agean conference Travel Award

As part of the 3rd International Conference on Cytokine Signaling in Cancer in Rhodes, Greece, the Travel Awards were again awarded this year. Two of the awards went to Sebastian Kollmann from the Institute of Pharmacology and Toxicology and Anna Orlova from the Department of Functional Cancer Genomics at Vetmeduni Vienna. In the project “STAT5A and STAT5B in Hematopoietic […]

Young Investigator Award for SFB PhD Student Tobias Suske

Tobias Suske is a PhD student in the group of Richard Moriggl at the Institute of Animal Breeding and Genetics, Vetmeduni Vienna. He was honored with the Young Investigator Award at the Annual Meeting of the OeGHO & AHOP in Linz AT for his excellent talk on “The gain-of-function STAT5BN642H mutation as a driver of […]

How the structure of STAT5B turns a normal cell into a cancer cell

In a triple-effort between international research groups from the University of Veterinary Medicine Vienna, Harvard University and the University of Toronto, important new information was discovered about the protein STAT5B, which is mutated in patients with T-cell cancers. STAT5B, like all proteins, is made up of building blocks called amino acids. A single amino acid […]

Young Investigator Award for Tobias Suske

Tobias Suske, PhD student at the Institute for Animal Breeding and Genetics at Vetmeduni Vienna, was awarded at the Annual Meeting of the Austrian Society for Hematology and Medical Oncology (OeGHO) and the Working Group for Hematological and Oncological Nurses (AHOP) spring conference 2019 for his outstanding presentation “The gain-of-function STAT5BN642H mutation as a driver of […]

New treatment option for leukemia

An international research team led by Veronika Sexl from Vetmeduni Vienna and supported by other members of SFB ‚JakStat Monarchies‘ have made an important discovery that could lead to a better understanding of lymphocytic leukemia: the STAT5B protein – but not the highly related STAT5A isoform – is crucial for disease development by suppressing interferon […]

STAT1 and myeloid cells – a mutual interplay in blood cell formation outside of the bone marrow and in early antiviral defence

We used conditional ablation of STAT1 in macrophages, monocytes and granulocytes of mice and showed that myeloid STAT1 protects from early murine cytomegalovirus replication and pathology in spleen. Unexpectedly, we found that myeloid STAT1 drives extramedullary haematopoiesis (EMH). STAT1 promotes EMH not only after virus infection but also upon sterile inflammation induced by CpG oligodeoxynucleotides. […]

Natural killer (NK) cells differentially require TYK2 for fighting tumours and bacterial infections

We used conditional ablation of TYK2 in mice and showed that TYK2 promotes NK cell activity in tumour surveillance and the defence against Listeria monocytogenes infection through cell-extrinsic and -intrinsic mechanisms. The key discoveries are as follows: NK cell-extrinsic TYK2 drives peripheral NK cell maturation, demethylation of the Ifng locus, activating receptor-induced IFNg production, cytotoxicity […]

New treatment approach against leukemia

An international research team led by researchers from Vetmeduni Vienna have made an important discovery that could lead to a better understanding of lymphocytic leukemia. They identified the STAT5B protein as crucial for the development of the disease. The findings represent a possible therapeutic approach involving new, precision medicine strategies. The BCR/ABL fusion gene, which […]
