We explore how biomolecular structure drives cellular communication. Our research combines cutting-edge NMR spectroscopy with molecular and cellular biology to reveal how mitochondrial DNA, RNA, and their protein partners regulate cellular signaling, metabolism, and immune responses. By studying biomolecules directly in their native cellular environment, we aim to uncover the structural principles that govern cellular adaptation in health and disease.
Mitochondria communicate with the rest of the cell not only through metabolites and proteins but also through RNA molecules. Increasing evidence suggests that mitochondrial RNAs can be selectively exported from mitochondria and packaged into extracellular vesicles, where they contribute to communication between cells. However, the mechanisms controlling this transport remain largely unknown. We investigate how RNA secondary structures, including G-quadruplexes and hairpins, together with RNA-binding proteins such as GRSF1, YBX1, and hnRNPA1, determine the intracellular trafficking and intercellular transfer of mitochondrial RNAs.
Mitochondrial DNA is normally confined within the organelle, but cellular stress can trigger its release into the cytoplasm, where it acts as a potent danger signal. This process links mitochondrial dysfunction to inflammation, autoimmune diseases, neurodegeneration, and cancer, yet the molecular mechanisms controlling mtDNA release remain poorly understood. Our research focuses on the structural organization of the mitochondrial D-loop region and its interaction with the outer membrane protein VDAC1 to understand how mitochondrial DNA initiates innate immune signaling through the cGAS–STING pathway.

Michaela is a structural biochemist working at the interface of structural biology and cell biology. Throughout her career, she has developed and applied advanced NMR-based approaches to investigate biomolecules directly in their native cellular environment, from living cells to intact mitochondria. During her PhD at Masaryk University, she pioneered the application of in-cell NMR spectroscopy to study nucleic acids in living cells. She subsequently joined Utrecht University as an EMBO Postdoctoral Fellow, where she expanded her expertise in mitochondrial structural biology. Her scientific achievements have been recognized by the Jean-Marie Lehn Prize in Chemistry and competitive national and international funding, supporting the establishment of her independent research programme, the BioSCom Lab, at Masaryk University.
We believe that understanding biomolecular function requires studying biomolecules directly in the environment where they naturally function. Our research integrates structural biology with molecular and cellular approaches to connect atomic-resolution structures with biological function.
