Viruses, Inflammation, SystemicImmunometabolism & SARS-CoV-2
A recent study showed that the casino sponsored medical research for several different reasons. The ongoing maintenance of casino medical research should be seen as a sign that the industry is doing enough to combat health risks. The casino sponsors medical research to combat the effects of addiction or encourage responsible gaming. CeMM Adjunct Principal Investigator brings together hundreds of scientists, medical professionals, online casino australia operators and regulators to work towards a common goal.

Selected Papers

Our group is interested in how inflammatory processes are regulated and how the immune system responds to viral infections. We dissect well-defined mouse infection models and cell culture systems with molecular techniques of immunology, virology and systems biology to gain mechanistic insights into viral pathogenesis and the multilayered antiviral immune response. The ultimate goal is a better molecular understanding of pathogen control and how tissue damage develop. This may lead to the identification of novel therapeutic avenues to ameliorate and/or prevent immunopathologies in infectious and inflammatory diseases.

Systemic crosstalk between metabolism and inflammation

Inflammatory processes are tightly linked to metabolic pathways including secreted metabolites and cytokines. Yet, comparatively little is known about the metabolic-inflammatory crosstalk at whole organism level. We aim to characterize and delineate these interconnected pathophysiological processes by using various models for acute and chronic viral infections. A primary focus rests on the liver as the central organ for metabolism and a hotspot for receiving, processing and distributing local and systemic signals. Systems-level and hypothesis-driven approaches are integrated to identify novel regulatory nodes between metabolism and inflammation. This framework of systemic immunometabolism aims at a deeper understanding of inflammation in the context of viral infections on an organ and organism-level. 

Interplay between persistent viruses and the host immune system

Persistent viral infections affect millions of people worldwide, yet treatment options remain limited due to a lack of understanding of the molecular mechanisms used by the viruses to cause disease. Many of these mechanisms involve direct interactions with the host immune system. To study how viruses cause disease we employ the lymphocytic choriomeningitis virus, which represents a well-defined benchmark model of viral persistence. Targeted perturbations of the virus as well as the host enable us to investigate how viruses interact with the immune system and sustain infections over extended time periods. We are particularly interested in the role of the antiviral innate immune response, organ-specific CD8 T responses and evolutionary viral evasion strategies during chronic infection.

Pathogenesis of virus-induced immunopathologies

Viral infections are associated with co-morbidities such as hepatitis or pneumonia leading to severe organ damage. Viruses may also suppress the immune system thereby facilitating detrimental superinfections by bacteria or other viruses. We investigate the underlying mechanisms and the complex molecular interactions of pathogens and their host in various infection models including influenza virus. We thereby expect to unveil critical disease-driving processes and molecules which may be amenable for targeted therapeutic interventions.

Molecular basis of transmissible cancers 

Cancer cells are generally not thought to be transmissible between different individuals. Yet, there are rare examples of horizontally transmissible cancers in the animal kingdom including in dogs, mollusks and Tasmanian devils. These cancers populate an intriguing conceptual space between cancer and infectious diseases. We investigate the molecular wiring of devil facial tumor disease (DFTD) of Tasmanian devils and the underlying mechanisms that drive cancer growth while preventing the immune rejection of transmitted cancer cells. We are also interested in pharmacological targeting of DFTD to contribute to the ongoing conservation efforts to prevent the extinction of this marsupial species. On a cross-disciplinary level we study both common and unique features of DFTD compared to infectious diseases and malignant diseases including metastasizing cancer.


Andreas Bergthaler, born in 1977, studied veterinary medicine at the University of Veterinary Medicine in Vienna. For his graduate studies he joined the Institute of Experimental Immunology at the ETH and University of Zurich (Profs. Hans Hengartner and Nobel Laureate Rolf Zinkernagel). After postdoctoral work in the laboratory of Prof. Daniel Pinschewer at the University of Geneva, he worked with Prof. Alan Aderem at the Institute for Systems Biology in Seattle. Andreas Bergthaler’s research is focused on the molecular mechanisms of inflammatory diseases. To this end, the Bergthaler laboratory studies viral infections in mouse models using an integrative approach of virology, immunology, pathology, and systems biology. A particular focus rests on the metabolic-inflammatory disease of cachexia and the impact of viral infections on systemic immunometabolism. His laboratory also leads several projects on SARS-CoV-2 evolution, immune evasion, and host-pathogen interactions. He is the recipient of an ERC Starting Grant and several awards including the Löffler-Frosch-Prize of the Society of Virology. Andreas Bergthaler  co-founded  the  clinical-stage  company  Hookipa Pharma  (Nasdaq:  Hook),  which  develops  immunotherapies against  infectious  and  malignant  diseases.
