ERC Starting Grant
ZINF Young Investigator Nicolai Siegel has been awarded a highly prestigious European Research Council (ERC) Starting Grant for 1.5 million Euros over 5 years to study how genome organisation influences antigenic variation in parasites.
Many pathogens, including parasites, bacteria and fungi, switch the identity of their surface molecules so that they are able to continuously evade the host immune system, a process called antigenic variation. Parasites such as Trypanosoma brucei, the causative agent of sleeping sickness, express a single version of a surface protein at any one time. This protein is recognized as foreign by the immune system, which produces antibodies to help eradicate the pathogen. However, the parasite is able to periodically switch the identity of the surface coat protein, to a version that is no longer recognized by the current repertoire of antibodies in the body. This enables it to evade the immune response until antibodies are generated against the new surface protein.
Despite the phenomenon of antigenic variation being recognized over a century, it is not well understood how a parasite ensures a single surface protein is expressed at a time and how it ‘decides’ which surface protein should be subsequently produced. Using a number of state-of-the-art approaches, Nicolai Siegel will investigate how the parasite’s genome is organized in three-dimensional space and if the relative location of surface protein genes in the nucleus is a determining factor of which surface protein is expressed and visible to the immune system at any one time. Elucidating the general principles of nuclear architecture and its role in antigenic variation will provide new therapeutic strategies that will interfere with a fundamental immune evasion strategy of the parasite and help facilitate its clearance.
The EU-funded ERC Starting Grants aim to support up-and-coming research leaders who are establishing an independent research group in Europe. This year just under 3000 applicants applied for the prestigious grants in the sections Physical Sciences & Engineering, Life Sciences and Social Sciences & Humanities and 325 projects were funded through the scheme, 9 of which went to researchers in the field of infection and immunity.

Campylobacter post-transcriptional regulatory networks and RNA localization
New research published in Nature Communications from the ZINF group of Cynthia Sharma and the group of Markus Sauer from the Biocenter describes the role of the post-transcriptional regulatory CsrA-FliW network in flagellar regulation of the human pathogen Campylobacter jejuni – a major cause of bacterial gastroenteritis.
Post-transcriptional regulation in bacteria is often the result of a complex cross-talk between mRNAs, small RNA (sRNAs) and protein regulators. The widespread CsrA (Carbon storage regulator) protein is a global regulator that binds to the 5’ region of bacterial mRNAs and represses their translation. In many species its activity is controlled by two antagonizing sRNAs that sequester CsrA. How this global regulatory circuit is controlled in species that lack these sRNAs is unclear. Gaurav Dugar and colleagues globally analysed the RNAs that associate with CsrA in the Epsilonproteobacterium Campylobacter jejuni and found that the mRNA encoding the major flagellin acts both as a target and a regulatory “sponge” for CsrA together with the main CsrA-antagonist, the protein FliW. Using confocal and super-resolution imaging, they also show that the flagellin mRNA localizes to the cell poles in a translation-dependent manner that is impacted by the CsrA-FliW post-transcriptional regulatory system.

New approach to understanding host-pathogen interactions
New research published in Nature from the IMIB group of Jörg Vogel describes a new method, dual RNA-seq, which provides insight into how pathogens change their gene expression patterns upon invading a eukaryotic cell and how the host cell responds to the infection.
Elucidating the molecular events by which a pathogen infects a host cell and the corresponding response is crucial to understanding of host – pathogen interactions and the development of intervention strategies. Many genes can be identified that are required for the efficient infection of an animal, however, in many cases the difficulties arise in trying to understand the precise role of the encoded protein or RNA in the infection process. Many examples exist where deletion of the gene fails to provide an observable effect in cell-based laboratory assays. This is especially true for many of the recently identified non-coding RNAs – whose function is to fine-tune gene expression - rendering their functions obscure.
Members of the Vogel lab, notably PhD student Alexander Westermann and several bioinformaticians at the IMIB, explored the feasibility of using next generation sequencing technologies to describe the RNAs present in both Salmonella and infected human cells at different time points during the infection. The resulting changes in both the bacterial and host transcriptomes suggest a dynamic host-pathogen interplay at the level of gene expression. Importantly, a bacterial small RNA, PinT, was highly upregulated upon internalization by the host cell. Deletion of the PinT gene revealed dramatic changes in both the host and pathogen transcriptomes, despite not showing an effect in cellular based assays, with subsequent molecular analysis identifying it to be an important regulator of virulence programs. The loss of the sRNA also caused corresponding significant changes in the host cytokine response and signaling pathways in the human cells.
Therefore, dual RNA-seq can be used to comprehensively chart the dynamic RNA expression landscape of both a bacterial pathogen and its eukaryotic host during the course of infection. The one-step nature of dual RNA-seq should enable high-throughput studies to unravel such hidden gene functions in pathogen and host simultaneously, during infection with Salmonella and many other pathogens.

Evolution of cellular circuits
Christian Perez has received funding from the Bavaria California Technology Center (BaCaTeC) to facilitate his work with Prof. Polly Fordyce at Stanford University on the molecular mechanism involved in the evolution of gene regulatory circuits in Candida albicans.
The ability to control gene expression is essential for most cells to function properly. At its core, this control is provided by sequence-specific DNA binding proteins. Recent work has shown that small changes in the binding specificities of these proteins over evolutionary timescales can drive the emergence of new traits in many organisms. This finding raises fundamental questions about the mechanisms that make this possible: What type of modifications can these proteins undergo and how do these changes impinge upon the regulatory circuitry of an organism? In collaboration with Dr. Fordyceâ€™s group at Stanford University, the Perez lab will determine the full profile of DNA sequences that a family of yeast transcription factor proteins can recognize along with their specificity and binding affinity. This information will allow them to infer a logical series of steps that led to the divergence of this family of proteins and the novel functions that they acquired.
The mission of BaCaTeC is to increase and promote cooperation between researchers located in Bavaria and California. It provides a basis for identifying potential partners and assists with initial contacts if necessary. BaCaTeC also sponsors projects with seed money to start up new collaborations.
Antibiotic Resistance Research
Antibiotic resistant bacteria are a matter of increasing medical and public concern. The issue is highlighted in DIE ZEIT (20th Nov) and covers the link between industrialised animal husbandry and the occurrence of multidrug resistant human pathogens such as methicillin-resistant S. aureus (MRSA) – a topic of research at IMIB.
The article includes recent work from the BMBF-funded MedVetStaph consortium which brings together experts from microbiology, epidemiology and veterinarian sciences to study the epidemiology of livestock-associated (LA)-MRSA. The research has identified an association between high antibiotic use in intensive mass animal farming and the selection and spread of LA-MRSA. These multiresistant bacteria are detectable in food samples, but also colonise companion animals and humans, finally finding their way into hospital settings where they add to the increasing burden of healthcare associated infections.
The IMIB contributes to the MedVetStaph programme through a project led by Dr. Wilma Ziebuhr, dealing with the early detection and analysis of novel resistance genes against last resort antibiotics in environmental samples from farm holdings. The goal of the project is to assess the risk potential of bacterial populations in animal husbandries as reservoirs for the generation and spread of novel antibiotic resistance genes.

EMBO Practical Course Non-coding RNA in Infection
The first EMBO Practical Course Non-coding RNA in Infection was held at the Institute for Molecular Infection Biology during October. The course included lectures from many leading scientists in RNA Biology
Many leading researchers volunteered their time to participate in the teaching of the course including Shoshy Altuvia, Ana Eulalio, Matthias Hentze, Michael Kiebler, Miguel Mano, Hanah Margalit, Nikolaus Rajewsky, Pascale Romby, Cynthia Sharma, Rotem Sorek, Jörg Vogel, Olivier Voinnet and Gerhart Wagner. Many IMIB staff also took part in helping running the practical aspects of the course ensuring its success.
The aim of the course was to provide a limited number of students with hands-on training in the techniques required to identify and characterise eukaryotic and prokaryotic RNAs involved in the infection process. The motivation for the course was the recognition that regulatory RNA molecules from pathogenic bacteria have important functions in virulence control while host non-coding RNAs are involved in the response to infection. However, for many relevant pathogens a systematic and comprehensive understanding of the role of non-coding RNAs in the infection process has not been achieved. Moreover, in many of the cases where non-coding RNAs have been identified, their targets and functions are yet to be determined. In the end it was a lively and fun week attended by eighteen mid-to-late-stage PhD students and early postdocs from both the prokaryotic and eukaryotic fields.
RNase Controls Malaria Parasite Antigen Expression
The molecular basis for how the malaria parasite Plasmodium falciparum evades the host immune system is not well understood. Work from ZINF Young Investigator Nicolai Siegel together with researchers at the Pasteur Institute published in Nature reveals an unanticipated role for an RNase in the process.
Plasmodium falciparum periodically switches expression between different var genes that code for the erythrocyte membrane protein 1 (PfEMP1). While the Plasmodium genome contains 60 var genes, only a single var-family member is expressed at any one time on the surface of infected erythrocytes and the change in expression enables the parasite to evade the adaptive immune response. The mechanism by which this monoalleic expression occurs is poorly understood but evidence suggests that it involves various epigenetic mechanisms involving histone modifications. In the current study, researchers at the Pasteur Institute in Paris asked the question whether other post-transcriptional mechanisms are involved. They identified a non-canonical exoribonuclease, which they called PfRNase II. The enzyme localises to the nucleus, where it degrades single stranded RNA. Monoallelic expression of var genes is disrupted in parasites expressing a deficient version of the exoribonuclease leading to the simultaneous expression of several family members. Importantly, there is an inverse relationship between levels of PfRNase II and the upsA-type var genes in parasites from severe malaria patients, indicating an important role for the enzyme in the infectious disease.
Evolution of Antibiotic Resistance
Reporting in the journal Cell, the laboratory of ZINF Young Investigator Daniel Lopez has revealed a new route by which the bacterial pathogen Staphylococcus aureus can evolve vancomycin resistance in the absence of the antibiotic but involving interactions between different subpopulations of cells.
The prevalence of antibiotic resistance is currently an important issue, which threatens our ability to treat infectious diseases. Consequently, the World Health Organisation has recently stated that we could be entering the post-antibiotic era. It is therefore important to understand how antibiotic resistance evolves to enable us to identify potential new strategies to combat these resistant pathogens.
Traditionally antibiotic resistance has been seen as the acquisition of mutations or new genes that render a microbe less susceptible to antibiotic treatment. These genetic variants are selected and propagated in the presence of broad-spectrum antibiotics due to a strong selection pressure. However, Gudrun Koch and colleagues from the Lopez lab have revealed that decreased susceptibility can occur even in the absence of antibiotic due to interactions between different bacterial strains within a population.
Working with a virulent antibiotic resistant strain of the Gram-positive pathogen Stapylococcus aureus, methicillin resistant Staphylococcus aureus (MRSA), they have observed the strain evolve over time in conditions that favour serious chronic infections in patients. The initial strain evolves to secrete more toxins and natural antibiotics to obtain a growth advantage, in response to this the original strain adapts to become resistant to these secreted products. As a consequence the final strain has the characteristics of pathogens that are resistant to multiple antibiotics including the last resort antibiotic vancomycin, which is the last line of defense against drug-resistant S. auerus. This has serious potential implications for the treatment of such infections and suggests that interactions between bacteria at the sites of infections could also be important to understanding the process of pathogenesis as well as the development of antibiotic resistance.

Helicobacter host adaptation
Understanding how bacterial pathogens adapt and take advantage of changing environmental conditions not only provides new insight into the cause and persistence of infectious diseases but also identifies new potential intervention strategies. New research published in the recent issue of the Proceedings of the National Academy of Sciences (PNAS 111(4):E501-10) from the ZINF young investigator group of Cynthia Sharma demonstrates how variable DNA sequences in the gastric pathogen Helicobacter pylori determine the outcome and fine-tuning of small RNA-mediated post-transcriptional gene expression control.
Many pathogens endure extreme variations in environmental conditions such as temperature, nutrient availability, and acidity or different niches within the host. Rapidly adapting to these changes is important for the colonisation, persistence, and spread of a pathogen within the host. This is especially important for the human pathogen Helicobacter pylori , which can persistently colonize the extreme acidic environment of the stomach in about 50% of the worldâ€™s population leading to gastritis, ulcers, and even gastric cancer. Similarly to other pathogens, it is important for H. pylori to be able to generate a level of phenotypic variability within a population through phase-variation. This process increases genomic variation, thereby facilitating the selection of beneficial mutations that enable the pathogen to adapt to new conditions. For example, H. pylori possess more than 50 genes with hypervariable simple sequence repeats (SSRs) which can undergo length variation as a consequence of replication errors. Length variation within SSRs can affect the expression of virulence associated genes and the mechanism by which this occurs been mainly viewed as mutations in DNA sequences that disrupt the coding regions of genes or their regulatory elements. However, their impact on RNA regulation is less understood. In the current study, PhD student Sandy Pernitzsch and Cynthia Sharma have identified a new mechanism of how variable SSRs can affect small RNA-mediated post-transcriptional regulation of a chemotaxis receptor in H. pylori.
Pernitzsch and Sharma describe how a highly expressed small RNA, RepG, from H. pylori interacts with the mRNA and thereby represses the expression of the pH-sensing chemotaxis receptor tlpB, a virulence factor involved in colonisation and inflammation of the stomach. Interestingly, the RepG sRNA, which was identified in a previous global transcriptome study by the authors, directly binds to a stretch of 12 guanines in the 5â€™ untranslated region of the tlpB mRNA, which corresponds to one of the variable SSRs in H. pylori. However, due the unusual location of this SSR its mechanism and impact on gene expression was unclear since it did not easily fit with previous models of phase variation. Analysis of the genome sequences of more than 30 Helicobacter strains revealed that while the sequence of the small RNA is highly conserved, the length of the SSR in the tlpB mRNA varies between 6-16 guanines. Based on this observation Pernitzsch and Sharma could show using a variety of in-vivo and in-vitro experiments that the length of this homopolymeric repeat determines the outcome of small RNA-mediated regulation (activation or repression) by affecting the translation of tlpB mRNA.
Therefore, this study links for the first time small RNA-mediated regulation and phenotypic variation via variable repeats. Rather than the phase variable ON-OFF switch of regulation observed for frame-shift mutations within genes, changes in the length of these homopolymeric G-rich motifs in the 5â€™ untranslated region of mRNAs can fine-tune the expression of genes important for the colonisation of the host. Given the number of SSRs in pathogen genomes this mechanism is likely to a more widespread phenomenon leading to rapid adaptation.

ERC Starting Grant
Congratulations to Daniel Lopez who has been awarded a highly prestigious European Research Council (ERC) Starting Grant for 1.5 million Euros over 5 years to study the role of cell signalling in bacterial pathogenesis.
The EU-funded ERC Starting Grants aim to support up-and-coming research leaders who are establishing an independent research group in Europe. This year over 3000 applicants applied for the prestigious grants in the sections Physical Sciences & Engineering, Life Sciences and Social Sciences & Humanities and 287 projects were funded through the scheme, 46 of which went to researchers in Germany.
Daniel Lopez will study the assembly and organization of discrete lipid microdomains that are present in the membranes of bacterial pathogens such as Staphylococcus aureus. These â€˜lipid-raftâ€™ membrane domains are important for the organization of signaling pathways and their disruption leads to changes in the physiology of the pathogen. For example, treatment of bacteria with small molecule drugs that disassemble these microdomains leads to a concomitant decrease in processes associated with bacterial virulence. Therefore, a better understand of the organisation of signalling pathways and how they affect pathogenesis may provide an alternative strategy for generating antimicrobial drugs.

Non-coding RNAs Hit The Sweet Spot
New research published in Cell from the IMIB group of Jörg Vogel provides new insight into how bacteria rapidly respond to sugar stress by using a novel RNA-based mechanism of gene activation to rapidly export toxic sugars.
Control of glucose homeostasis is a key regulatory function that has been described in all kingdoms of life. The uptake of glucose is accompanied by a phosphorylation event that is vital for its intracellular retention. However, while phosphosugars are key metabolic intermediates, their intracellular levels must be tightly regulated since high levels are toxic and strongly impair cell growth and cause DNA damage. To relieve the sugar-induced stress, bacteria prevent further expression of sugar transporters in the membrane, which is achieved by extensive transcriptional and post-transcriptional control. However, given the protein stability of the membrane transporter, which only decreases by 50% in three generations, this mechanism cannot be responsible for immediate relief. Therefore, how cells contend with acute sugar stress is not known.
Bacteria contain a large number of regulatory small RNAs (50-250nts) that are involved in the post-transcriptional regulation of gene expression. These small RNAs (sRNAs) typically repress the expression of mRNAs by either base-pairing with their targets and preventing the binding of ribosomes or facilitating the recruitment of RNA decay factors. For the few sRNAs that positively affect gene expression these function by relieving previous inhibitory structures that prevent the translation of specific RNAs.
SgrS is a small RNA that accumulates under conditions of sugar stress and has been shown to negatively regulate the expression of the glucose transporter PtsG, however, when the Vogel lab analysed the SgrS regulon, among the know targets, they identified an unknown gene that was induced by the sRNA. Further analysis of this gene, YigL, identified it as the long sought after phosphatase that dephosphorylates glucose-6-phosphate and thereby facilitates sugar export, providing a rapid way to relieve sugar stress. Importantly the induction of YigL occurred by a novel mechanism, whereby SgrS binds to a sequence just upstream of the YigL gene and inhibits the constitutive turnover of the mRNA by the ribonuclease RNase E, resulting in a rapid increase in yigL mRNA levels. Furthermore, the binding of the sRNA to yigL containing transcript was shown to be essential for sugar efflux and the recovery from sugar-stress.
The novel mechanism by which an sRNA inhibits the constitutive turnover of an mRNA provides an extremely rapid mechanism to alter gene expression in response to changing environmental conditions. Current studies suggest that it may be more wide-spread since other sRNAs have already been identified that activate gene expression by stabilising transcripts. Importantly, this activation mechanism of gene expression does not require the synthesis of new regulators, thereby rapidly relieving environmental stress without relying on the turnover of the stable sugar transporters in the membrane, which may be important for long term environmental adaptation to chronic high sugar levels.

Fishing for complement aids malaria parasite survival
Malaria is a major health burden causing 655,000 deaths annually. During its lifecycle, transmission of the malaria parasite from an infected human requires that the Anopheles mosquito takes up erythrocytes that contain gametocytes, sexual precursor cells of the parasite, during its blood meal. Once in the mosquito, sexual reproduction of the parasite occurs in the midgut before subsequent entry into a new human host during feeding. Throughout itâ€™s lifecycle the parasite must evade components of the immune response found in the human blood. Until now it was not clear how Plasmodium evades the complement response, which involves the sequential assembly of a membrane bound complex that induces lysis of foreign infecting cells.
Previously, the sexual stages of the parasite had been shown to be sensitive to lysis by the complement system, which enters the mosquito midgut together with the blood meal. The Pradel lab were interested in how the parasite could avoid lysis to enable transmission to a new host. Initial observations agreed with previous work - that the alternative pathway of complement impaired gametogenesis, however, they were able to show that this was antagonized by a human host complement regulatory factor, FH. Normally, this regulatory factor inactivates complement components preventing them from targeting and lysing the hostâ€™s own cells. However, during infection the parasite expresses a protein, PfGAP50, which relocalises from an inner compartment to the plasma membrane once the gametocyte enters the mosquito midgut. This protein acts as the receptor for FH recruiting it to the parasites surface thereby protecting it from lysis and increasing the transmission of Plasmodium to the mosquito.
The Pradel lab, which has recently moved to RWTH Aachen University, is now aiming to utilise this complement evasion mechanism to block transmission of malaria parasites by the mosquito. They are evaluating complement evasion as a target for transmission blocking vaccines together with the nearby Fraunhofer Institute of Molecular Biology and Applied Ecology, who recently launched the Fraunhofer Future Foundation Malaria Project to develop and manufacture new malaria vaccines.
Graduate School of Life Sciences Fellowships
Congratulations to IMIB PhD candidates Benjamin Mielich-Süß and Caroline Tawk who have been awarded PhD fellowships from the University of Wurzburgâ€™s Graduate School of Life Sciences.
Benjamin was born in Ellwangen, Germany and obtained his undergraduate and Master degrees in Biology from the University of Würzburg. He will undertake his PhD in the Lopez lab where he will focus on the role of lipid rafts in the pathogen Staphylococcus aureus.
Caroline was born in Moscow, before studying for her Biology and Biochemistry degree at the Université Saint Joseph in Lebanon, this was followed by obtaining her Masters from the American University of Beirut in Molecular and Cellular Biology. Caroline recently joined the Vogel lab where she is investigating if bacterial effector proteins are able to target host RNAs.
Both were successful in a highly competitive fellowship selection process. The graduate school received over 200 applications from which 50 candidates were selected for interviews for a total of 10 fellowships.
DFG supports Staphylococcus research at IMIB and ZINF
The Deutsche Forschungsgemeinschaft (DFG) has funded two research projects in the Lopez and Ziebuhr labs that aim to provide new insight into Staphylococci infections.
Staphylococci are a prominent cause of acute and chronic infections, the persistence of infection is linked to the ability of these bacteria to form biofilms. Biofilms are surface-attached bacterial communities that are encased in an extracellular matrix, these structure render the bacteria refractive to the action of antimicrobials and the immune system. Therefore, the inhibition of biofilm formation has been targeted as a therapeutic strategy for the treatment of chronic infections.
The Lopez lab will focus on investigating the role of cellular differentiation and if distinct cell subpopulations play specific roles in biofilm formation and virulence in S. aureus. The Ziebuhr lab will examine the variability in gene expression and metabolism in different cell types during the formation and establishment of S. epidermidis biofilms.
The goal of the studies is to better understand the biofilm formation process and to identify new targets for antimicrobials.
Alex Westermann in double prize glory
The first week of October turned out to be particular productive for PhD student Alex Westermann (Vogel lab) as his poster won top prize at two consecutive meetings.
Alex presented his poster “Dual RNA-seq of Host and Pathogenâ€ at the 64th Annual Meeting of the German Society for Hygiene and Microbiology in Hamburg, before travelling directly to the 7th Meeting of the GBM Study Group RNA Biochemistry in Bonn. At both meetings he was awarded the prize for the best poster.
European Meeting on Gene Expression in T. brucei
The meeting is organized by Nicolai Siegel (ZINF) and Susanne Kramer (Dept. Cell and Developmental Biology) from the University of Würzburg. It brings together leading scientists from around Europe who have a joint interest in understanding the different mechanisms involved in the regulation of gene expression in the parasite Trypanosoma brucei, the causative agent of sleeping sickness which affects tens of thousands of people worldwide. Prof. Christine Clayton, from the University of Heidelberg, will present the keynote lecture.

Further Funding for GSLS
The Graduate School of Life Sciences, University of Würzburg has been awarded further funding during the second phase of the German Excellence Initiative, which runs from 2012-2017.
The Excellence Initiative is run by the German Research Foundation (DFG) and the German Council of Science and Humanities with the goal of improving the quality of German Universities and promoting top-level research in the country. One approach is to fund dedicated graduate schools to promote early career researchers. Initially in 2006-2007 the Initiative funded 39 graduate schools throughout Germany and the federal and state governments decided in 2009 to continue the Excellence Initiative for a second phase. Upon submitting a proposal for the continued funding of the GSLS, the success of the school was evaluated by the DFG in a meeting in Bonn during Feb 2012. The GSLS sent a delegation of 25 representatives for the evaluation which include Prof. Vogel, Prof. Moll and Iris Gonzalez Leal from IMIB, the hard work and preparation of the team clearly paid off, since the presentations were well received and it was announced in June that the GSLS would be funded by the Excellence Initiative until 2017.

W2 professorship for Alex Boehm
Congratulations to Alex Böhm on accepting an offer of the W2 Professorship of Synthetic Microbiology at the LOEWE-Centre for Synthetic Microbiology at the University of Marburg, to where he will move his lab in July 2012.
Alex joined IMIB in 2010 as an independent group leader where he focused his work on how bacteria sense and respond to altering environmental conditions. A key aspect of this response is how signaling pathways control the formation of surface associated bacterial communities, which is of great medical importance in combating specific chronic infections. In Marburg Alex will switch the emphasis of his research and take a synthetic microbiology approach to the de novo assembly of designer biofilms that can be used as an architectural scaffold for applied uses in areas such as tissue engineering.
W2 professorship for Sven Krappmann

Junior Research Group Position (BioSysNet)
March 19, 2012: Anna Eulalio has been awarded and accepted a junior research group position based on funding from the Bavarian Molecular Biosystems Research Network (BioSysNet). She will start her lab at IMIB in April 2012 and will focus on the consequences of bacterial infection on host cell RNA metabolism.
Ana obtained her PhD from the University of Coimbra and Center for Neuroscience and Cell Biology in Portugal. Her subsequent post-doctoral studies at the EMBL, Max Planck Institute for Developmental Biology, Max Planck Institute for Infection Biology and the ICGEB in Trieste focused on miRNA mediated silencing mechanisms and the role of these small RNAs during bacterial infection and in cardiomyocyte biology. She is supported with 1.5 million Euros fromthe Bavarian Research Network for Molecular Biosystems, which is funded by the Bavarian State Government to provide a basis for closer research alliance between Bavarian Universities. As a part of this goal the program funds a number of regular junior research groups in addition to associated junior and senior research groups.
Her new research project is aimed at investigating the consequences of pathogenic bacteria on RNA metabolism pathways in infected host cells, as well as the reciprocal effect of these pathways on the life cycle of pathogenic bacteria, issues that remain largely unexplored. The ensuing knowledge will lead to an unprecedented understanding of fundamental aspects of host – pathogen interactions, which may constitute the basis for the development of novel therapeutic approaches against infection by bacterial pathogens.
New ZINF Young Investigator
