Microbes (viruses, bacteria etc) and their hosts (complex multicellular organisms) co-exist for millions of years. This co-evolution led to the development of intimate interactions between both parties. Such interactions may be essential for the pathogen to replicate (e.g. recruitment of host factors) or for the host to limit spread of the pathogen (e.g. proteins of the innate immune system). Some pathogenic microorganisms, however, can evade the immune system and accellerate disease. Our group is interested in understanding the interactions between pathogenic viruses and their hosts on molecular and functional levels, focusing on RNA-protein and protein-protein interactions.
Congratulations to Anna and Valter for publishing a function role of the alternative CBC!
The alternative cap binding complex consisting of NCBP1 and -3 exports mRNA but is redundant under physiological conditions. However, virus infection or challenge with innate immune stimuli revealed a critical function of the alternative CBC in modulation of the innate immune system. This was particularly evident in NCBP3 deficient mice that showed increased susceptibility to influenza A virus infection.
Philipp’s work on Interferon Stimulated Genes uncovered many unknown functions of the innate immune system
Fantastic achievement that strengthens our positions at the front line of research
