Bacterial vesicles transport their bioactive cargo to the host nucleus. This project aims to investigate how bacterial membrane vesicles transport their cargo to the nucleus of cells and its impact on host cell functions. Bacteria use membrane vesicles as a means of communication with the host, but the full extent of their effects on host cells has yet to be fully elucidated. This project expects to generate new knowledge in the field using cutting-edge imaging and molecular biology approaches. ....Bacterial vesicles transport their bioactive cargo to the host nucleus.

This project expects to generate new knowledge in the field using cutting-edge imaging and molecular biology approaches. The work should provide significant benefits, particularly towards the development of membrane vesicles in gene therapy, gene editing and other applications. Read moreRead less

Summary
Understanding how bacteria adapt and function in the complex gut ecosystem. This project aims to investigate the role of the gut ecosystem in defining the structure and function of microbes. Given that one of the current challenges in microbiology is our inability to study individual microbes directly from complex, multi-microbial niches, this project aims to develop multidisciplinary methods to study microbes in their native state, to understand how they adapt to live in the gut. This understan ....Understanding how bacteria adapt and function in the complex gut ecosystem. This project aims to investigate the role of the gut ecosystem in defining the structure and function of microbes. Given that one of the current challenges in microbiology is our inability to study individual microbes directly from complex, multi-microbial niches, this project aims to develop multidisciplinary methods to study microbes in their native state, to understand how they adapt to live in the gut. This understanding should provide fundamental insights into adaptation mechanisms that lead to bacterial proliferation, disease and antibiotic resistance. As well as enhancing interdisciplinary collaborations, this work should provide economic benefits by contributing to improved gut health of animals, and more efficient food production.Read moreRead less
Structural Characterisation of the Type IX Secretion System. The Type IX Secretion System present in diverse bacteria of veterinary, agricultural, environmental and industrial importance enables effector proteins to be secreted and attached to the cell surface where they contribute to disease pathogenesis or degrade biopolymers of commercial interest. This project aims to determine the structure and assembly mechanism of this complex secretion nanomachine comprising 15 different proteins using s ....Structural Characterisation of the Type IX Secretion System. The Type IX Secretion System present in diverse bacteria of veterinary, agricultural, environmental and industrial importance enables effector proteins to be secreted and attached to the cell surface where they contribute to disease pathogenesis or degrade biopolymers of commercial interest. This project aims to determine the structure and assembly mechanism of this complex secretion nanomachine comprising 15 different proteins using state of the art microscopy. Knowledge of the structure will greatly enhance our understanding of secretion mechanisms and our ability to both inhibit the system to treat disease in animals or manipulate the system for industrial applications providing future economic and environmental benefits to our nation.Read moreRead less
