LncRNA and Infection Biology

The research group led by Mathias Munschauer investigates host and pathogen RNA-protein interactions in an infection context. They work towards obtaining a mechanistic understanding of RNA functions during infection, which will ultimately aid the development of host-directed therapeutics.

Our research and approach

Viruses are a burden to human health. Identifying host cell factors that bind and regulate viral RNA during infection processes is important for understanding how viruses can take over a host cell, subvert host processes and escape innate immune defense mechanisms. Insights into the underlying molecular interactions and mechanisms contribute towards the development of novel RNA-based therapies.

Mathias Munschauer´s group is charting a map of functionally important RNA-protein interactions for specific RNA types, ranging from host or pathogen encoded long non-coding RNAs (lncRNAs) to viral RNA genomes. Their work combines a cutting-edge suite of technologies from the fields of biochemistry, genomics, molecular biology and computational biology.

They investigate RNA molecules by creating a snapshot of their protein interactions using RNA antisense purification and mass spectrometry (RAP-MS). Interactions are then functionally dissected using RNA-seq, Ribo-seq and CLIP-seq technologies. The group´s overarching goal is to create a map of functionally important RNA-protein interactions during infection processes to guide the development of novel host-directed therapeutics.

Research projects

To effectively combat invading pathogens, host cells need to be able to rapidly adjust their gene expression programs and mount an effective host response. In addition to messenger RNA (mRNA), thousands of so called long non-coding RNAs (lncRNAs) are actively transcribed and specifically regulated as a result of bacterial or viral infections. While lncRNA resembles their protein coding counterparts in length, splicing structure, and biochemical properties, they do not serve as templates for protein synthesis. Hence, their physiological functions and biochemical mechanisms are challenging to dissect and in many cases remain poorly understood. 

Recent breakthroughs in DNA sequencing technologies led to the realization that many lncRNAs are potent regulators of various gene expression programs, including the host response to pathogens. Knowledge of hundreds to thousands of pathogen-responsive lncRNAs can be considered a treasure trove for discovering novel mechanisms of gene regulation and host defense strategies. 

Our group aims to decipher the genetic code controlling lncRNA function by obtaining a quantitative understanding of their molecular interactions and decoding the sequence features or structural elements that mediate these interactions. We seek to elucidate the composition of lncRNA complexes and aim to identify biochemical interactions that enable lncRNA functions. In this context, we are particularly interested in broadly exploring our recent finding that lncRNAs can modulate proteins and control their ability to assemble higher-order ribonucleoprotein complexes. Our group is developing and applying cutting-edge technologies to characterize direct interactions of individual RNA species with proteins at high resolution and in a quantitative manner. Ultimately, we hope to utilize insights into the mechanisms of lncRNA function in order to improve our understanding and ability to treat infectious disease.
