Weakening the defence of bacteria – a new potential therapy against infections
PhD defence, Friday 17 June 2022. Thorbjørn V. Sønderby
During his PhD studies, Thorbjørn V. Sønderby researched a very robust biological material, called functional bacterial amyloid. The material consists of thread-like fibrils which are found on the cell surfaces of many bacteria, where it provides protection against antibiotics and environmental changes. Thorbjørn V. Sønderby has studied the mechanism behind the formation of fibrils and together with international collaborators, found a new method to modulate the formation of bacterial fibrils using synthetic protein fragments called peptides. Thorbjørn has also investigated how we as humans can take advantage of the bacteria's very robust fibril material by "harvesting" it and using it in an artificial bio-nanomaterial.
The new research findings contribute to a better understanding of how we can treat certain types of bacterial infections and provide inspiration for future development of new exciting bio-nanomaterials.
The PhD study was completed at Interdisciplinary Nanoscience Center (iNANO), Faculty of Natural Sciences, Aarhus University.
This summary was prepared by the PhD student.
