5th International Conference on Cytokines in Cancer

Comments Off

The conference will be held at the Grecotel Kos Imperial, Kos, Greece on May 14-19, 2023. Organizing committee: Eleanor Fish, Belinda Parker, Serge Y Fuchs, Mathias Müller and Leonidas Platanias. The Conference is under the sponsorship of Aegean Conferences, a non-profit educational organization promoting science through focused scientific conferences (https://www.aegeanconferences.org).

The SFB members Anna Orlova and Richard Moriggl are co-founders of the pharmaceutical start-up RIANA Therapeutics spun out of Vetmeduni Vienna in February 2023. RIANA Therapeutics focuses on developing novel anti-cancer treatments with hope to improve life of cancer patients.

The SFB Jak-Stat subproject leader Veronika Sexl took the lead of the University of Innsbruck (https://www.uibk.ac.at/en/) in March 2023. Veronika was appointed head of the rectorate in an international selection process for a period of four years. The SFB members congratulate Veronika to this highly responsible and prestigious position. We will miss Veronika’s scientific excellence and spirit in our team and wish her a successful and fruitful time in Innsbruck.

Richard Moriggl – a long-term member of the SFB – will take over the leadership of the subproject ‘Partners in Crime: STAT3 and CDK6 Control Transformation in Hematopoietic Cells’. We highly appreciate the commitment of Richard and look forward to exciting interactions.

The JAK-STAT signaling pioneers James E Darnell, John J O‘Shea and George R Stark and former or current co-workers in their labs co-author a comprehensive review on the current knowledge on the cellular and systemic activities of JAKs and STATs and possibilities of their therapeutic targeting in disease settings (see https://doi.org/10.1016/j.cell.2022.09.023).

The Viennese JAK-STAT community congratulates this fascinating pathway to its 30ies anniversary!

  https://www.cmv2022.org Abstract of Oral Presentation Pdgfra-positive fibroblasts are a major site of mouse cytomegalovirus latency in vivo. Latent cytomegalovirus (CMV) infections pertain to most of the human population, yet our understanding of the cell types that carry latent CMV in vivo remains limited. While endothelial cells and macrophages have been identified previously as sites […]

Innate immunity to viral infection is achieved by a group of polypeptide mediators, the interferons (IFN). By binding to cell surface receptors they initiate signal transduction via Janus kinases (JAK) that the STATs target, a group of transcription factors. STATs combine to form a transcription factor, ISGF3, that activates transcription of a large number of IFN-induced genes (ISG) encoding antiviral proteins and establishing an antiviral state.
We show that the transcription of antiviral genes includes important changes of chromatin structure (see below). First, ISGF3 binds to the control region of ISG to induce a rearrangement of nucleosomes that creates maximal accessibility of the promoter (below middle panel). Second, ISG that are arranged in chromosomal clusters change their chromatin loop structure to increase the interaction of regulatory elements (below right panel). The molecular model emerging from the study posits that interaction in the 3-dimensional space creates regulatory hubs with the ability to influence the expression of several clustered genes simultaneously. This may help to both coordinate, accelerate and strengthen the establishment of the antiviral state.
