Nuclear alarmins escalate tissue immune responses. Humans and other animals are constantly exposed to potential threats, including microbes on and near the body. Animals can live with such dangers because these everyday encounters are made harmless by the immune system. It is unclear how cells distinguish low-danger threats from high-danger threats. This proposal seeks to reveal how immune cells identify increasing levels of threat and appropriately escalate their responses. Expected outcomes in ....Nuclear alarmins escalate tissue immune responses. Humans and other animals are constantly exposed to potential threats, including microbes on and near the body. Animals can live with such dangers because these everyday encounters are made harmless by the immune system. It is unclear how cells distinguish low-danger threats from high-danger threats. This proposal seeks to reveal how immune cells identify increasing levels of threat and appropriately escalate their responses. Expected outcomes include new insights into how immune cells and tissues respond according to the posing threat. Project benefits include understanding how to manipulate danger responses for future basic research and commercial applications, and fundamental understanding of how animals flourish in a dangerous world.Read moreRead less

Summary
Elucidating ATPase function during NLRP3 inflammasome assembly. Humans and animals are constantly exposed to microbes, which inhabit their external environment as well as body surfaces such as the skin and gut. We are, however, able to co-exist with these microbes, because our immune system protects us from these everyday encounters. This proposal will reveal how an important immune protein called NLRP3 senses microbes and other physiological processes. When NLRP3 senses such factors and is acti ....Elucidating ATPase function during NLRP3 inflammasome assembly. Humans and animals are constantly exposed to microbes, which inhabit their external environment as well as body surfaces such as the skin and gut. We are, however, able to co-exist with these microbes, because our immune system protects us from these everyday encounters. This proposal will reveal how an important immune protein called NLRP3 senses microbes and other physiological processes. When NLRP3 senses such factors and is activated, it induces the release of messenger substances to alert other immune cells. This research will deliver fundamental knowledge of how animals normally co-exist with microbes.Read moreRead less

Summary
Unifying mechanisms of innate immunity signaling in animals and plants. This project aims to improve our understanding of innate immunity, the first line of defense against pathogens in diverse organisms. Innate immune pathways are key to a range of pathological states in animals, and provide plants with resistance to the diseases that account for 15% of crop losses. This project will generate knowledge, through characterising mechanisms of cell signalling for mammalian and plant innate immunity ....Unifying mechanisms of innate immunity signaling in animals and plants. This project aims to improve our understanding of innate immunity, the first line of defense against pathogens in diverse organisms. Innate immune pathways are key to a range of pathological states in animals, and provide plants with resistance to the diseases that account for 15% of crop losses. This project will generate knowledge, through characterising mechanisms of cell signalling for mammalian and plant innate immunity. The outcomes will include a unified signalling model, and form the foundation for a range of applications in human biology and agriculture, such as the development of durable and effective resistance in crops.Read moreRead less
Molecular basis of nucleotide signalling by TIR domain containing proteins. Nicotinamide adenine dinucleotide (NAD+) dependent signalling pathways play important roles in neurodegenerative diseases and bacterial defence systems, and are therefore potential targets for the development of new therapeutics and biotechnology tools. This project aims to increase our understanding of the biology of a novel class of enzymes involved in NAD+ signalling across the domains of life. The project is expected ....Molecular basis of nucleotide signalling by TIR domain containing proteins. Nicotinamide adenine dinucleotide (NAD+) dependent signalling pathways play important roles in neurodegenerative diseases and bacterial defence systems, and are therefore potential targets for the development of new therapeutics and biotechnology tools. This project aims to increase our understanding of the biology of a novel class of enzymes involved in NAD+ signalling across the domains of life. The project is expected to unravel general principles of nucleotide-based signalling, and the expected outcomes will include new molecular mechanisms relevant to cell-death and pathogen defence in mammalian and bacterial systems, which should provide significant benefit for a range of applications in human biology and biotechnology.Read moreRead less
