Mutational Dynamics of SARS-CoV-2 in Austria: UK and South Africa variants found in Austria

Over the last few weeks, the United Kingdom and South Africa have faced a rapid increase in COVID-19 cases leading to enhanced epidemiological and virological investigations. Analysis of viral genome sequence data identified a sizeable proportion of cases belonging to new phylogenetic clusters. The new SARS-CoV-2 variants are defined by nonsynonymous, several of which are found in the viral spike protein, and still of uncertain functional significance. While it is known that viruses constantly change through mutation, and seldom does it lead to biological changes, the variants now increasingly observed in the UK and South Africa may be associated with increased infectivity.

Christoph Bock becomes Professor of Medical Informatics at MedUni Vienna

Christoph Bock has been appointed as professor of medical informatics at the Medical University of Vienna and head of the Institute for Artificial Intelligence and Decision Support at CeMSIIS, starting 1 January 2021. The bioinformatician and genome researcher joins MedUni Vienna from the neighboring CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences. He will continue to lead his research group at CeMM, complementary to the new tasks at MedUni Vienna.

Austrian study provides deep insights into transmission and mutation properties of SARS-CoV-2

Learning from past SARS-CoV-2 outbreaks for future pandemic control. In the COVID-19 pandemic, 57 million people have already been infected worldwide. In the search for vaccines and therapies, a precise understanding of the virus, its mutations and transmission mechanisms is crucial. A recent study by the research group of Principal Investigator Andreas Bergthaler at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences, in the renowned journal Science Translational Medicine, makes an important contribution to this. The high quality of epidemiological data in Austria, together with state-of-the-art virus genome sequencing, has supported unprecedented insights of the mutation behaviour and transmission of the SARS-CoV-2 virus.

Christoph Bock among the world's most highly-cited scientists in 2020

New EU-funded Research Project “HCA|Organoid”: Toward a Single-Cell Atlas of Human Organoids for Biomedical Research

HCA|Organoid is a new EU research project that combines single-cell profiling and organoid technology to validate organoids as faithful models of human biology. The project seeks to kickstart the development of an open access “Organoid Cell Atlas”. By creating well-characterized in vitro models of human organs, this resource will enable future discovery-driven and translational research on rare genetic diseases, complex multifactorial diseases, and on cancer. Toward this goal, Europe’s leading organoid researchers as well as experts in single-cell sequencing, single-cell imaging, and computational data integration have teamed up. The HCA|Organoid project is one of six pilot actions funded by the EU Horizon 2020 Framework Program that will constitute European contributions to the “Human Cell Atlas” – an ambitious global initiative striving to advance biomedical research and therapy using single-cell technologies. The HCA|Organoid consortium comprises eight partners and will receive EUR 5 million in EU funding.

Deep learning on cell signaling networks establishes interpretable AI for single-cell biology

Researchers at CeMM, the Research Center for Molecular Medicine of the Austrian Academy of Sciences, have developed knowledge-primed neural networks (KPNNs), a new method that combines the power of deep learning with the interpretability of biological network models. KPNNs learn multiple layers of protein signaling and gene regulation from single-cell RNA-seq data, thereby providing a much-needed boost in our ability to convert massive single-cell atlas data into biological insights. These findings have now been published in the renowned scientific journal Genome Biology.

Smart structures: Structural cells of the body control immune function

The human body is often seen as a “machine” that consists of specialized components: Bones and soft tissue provide structure, organs contribute physiological functions, and immune cells protect against pathogens. In reality, many cell types and organs may play more than one role. Researchers at CeMM, the Research Center for Molecular Medicine of the Austrian Academy of Sciences, have now discovered a striking example of multi-tasking cells. In a paper published in the scientific journal Nature, CeMM researchers analyzed the epigenetic and transcriptional regulation in structural cells, including epithelium, endothelium, and fibroblasts. They found widespread activity of immune genes, suggesting that structural cells are deeply involved in the body’s response to pathogens. Moreover, the study uncovered an “epigenetic potential” that pre-programs structural cells to engage in the immune response against pathogens. These findings highlight an underappreciated part of the immune system and open up an exciting area for research and future therapies.

Single-cell RNA seq method developed to accurately quantify cell-specific drug effects in pancreatic islets

Researchers from Stefan Kubicek's and Christoph Bock’s groups, at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences in Vienna, have developed a method to accurately assess the effect of specific drugs in isolated pancreatic tissue by using a refined single-cell RNA sequencing method. Their study published in Genome Biology describes the technique that they have developed to overcome the problem of contaminating RNA molecules in single-cell transcriptomics, which allowed for accurate results of dynamic drug responses in pancreatic cells. These findings will support the development of targeted drug therapies for the treatment of Type 1 diabetes in the future.
