Summary
Export of effector proteins by P. falciparum to the infected red blood cell. Infection by the malaria parasite has lethal consequences for humans. The parasite exports hundreds of proteins via a translocon to commandeer the red blood cell. This project aims to determine the function of one of the major translocon components and determine if it is a viable target for anti-malarial drug development.

Summary
Pathogen detection in mammals. This project aims to study the role of a host molecule in immune protection. Multicellular organisms need to recognise pathogens to initiate immune protection. To do this, pathogen-specific molecules are presented to the immune system causing activation. Recently a mode of pathogen recognition was discovered in mammals. As microbes synthesise essential vitamins, they release tell-tale metabolite by-products, which a host molecule called MR1 captures and presents to ....Pathogen detection in mammals. This project aims to study the role of a host molecule in immune protection. Multicellular organisms need to recognise pathogens to initiate immune protection. To do this, pathogen-specific molecules are presented to the immune system causing activation. Recently a mode of pathogen recognition was discovered in mammals. As microbes synthesise essential vitamins, they release tell-tale metabolite by-products, which a host molecule called MR1 captures and presents to white blood cells. However, it is not understood how MR1 accomplishes this, the cellular machinery required, or how the metabolites are guided to MR1. Understanding this process is expected to explain microbial pathogen recognition.Read moreRead less

Summary
Activity-dependent regulation of glutamate receptor trafficking in neurons. This proposal aims to understand the molecular mechanisms of neuronal communication and how neurons modify their synaptic strength. Although these processes are essential for normal brain function, the precise underlying mechanisms are not well understood.

This proposal aims to understand the molecular mechanisms of neuronal communication and how neurons modify their synaptic strength. Although these processes are essential for normal brain function, the precise underlying mechanisms are not well understood. This project will use structural, biochemical, molecular and cell biological assays to study the molecular processes that control glutamate receptor trafficking in the postsynaptic compartment. It will elucidate how neural plasticity is generated and maintained, information critical for understanding sensory processing, learning and memory throughout life. The findings could identify cellular targets for interventions to enhance cognitive performance and maintain optimal brain function.Read moreRead less

Summary
Revealing dynamic mechanisms controlling pluripotency in mammalian stem cells and embryos. Every cell of our mature bodies originates from 'pluripotent' cells present in the early mammalian embryo. These cells can be captured and grown in plastic dishes. The project will use imaging methods to reveal how gene regulatory molecules control pluripotent cells in the embryo and in culture.

Characterization of Novel Import/Assembly Pathways in Plant Mitochondria. In addition to their central role in metabolism, plant mitochondria have emerged as important hubs for both sensing and responding to a variety of stimuli. However, as yet there are still many unanswered basic questions about how mitochondria are built in plant cells. This project aims to characterise two novel protein import/assembly pathways, specifically, the newly identified twin-arginine translocation (Tat) protein as ....Characterization of Novel Import/Assembly Pathways in Plant Mitochondria. In addition to their central role in metabolism, plant mitochondria have emerged as important hubs for both sensing and responding to a variety of stimuli. However, as yet there are still many unanswered basic questions about how mitochondria are built in plant cells. This project aims to characterise two novel protein import/assembly pathways, specifically, the newly identified twin-arginine translocation (Tat) protein assembly pathway, and the disulphide relay system of the mitochondrial intermembrane space which displays unique characteristics compared to other systems. A mechanistic understanding of these pathways can be used to design novel strategies to alter plant growth and performance.Read moreRead less

This project aims to determine the mechanisms that connect signalling microdomains at the cell surface to intracellular signalling endosomes to regulate T cell activation.

This project aims to determine the mechanisms that connect signalling microdomains at the cell surface to intracellular signalling endosomes to regulate T cell activation. A T cell immune response begins with the reorganisation of the plasma membrane to yield two-dimensional signalling microdomains that must be connected to the three-dimensional microarchitecture of the endocytic matrix for full T cell activation. This project hypothesises that Flotillin form distinct signalling microdomains in the plasma membrane that internalise to constitute an independent endocytic pathway. Using single-molecule and ultra-fast fluorescence imaging, the project will demonstrate that Flotillin represent a unique two-dimensional to three-dimensional regulatory mechanism for T cell signalling.Read moreRead less

This project seeks to determine how protein interactions with membrane lipids regulate recruitment to cellular organelles, providing new insight into the complex pathways of cellular homeostasis. Controlling the distribution of proteins within cells is critical for cell signalling and membrane trafficking. This is orchestrated by the interaction of specific protein modules with lipids on the surface of different organelles. The phox homology (PX) domain is a lipid-binding module found in numerous proteins essential for normal cell trafficking and homeostasis, and perturbed in many conditions including immune dysfunction and cancer. This project plans to investigate molecular determinants of PX-lipid association, generating knowledge about protein-membrane interactions required for cellular function. These insights may underpin future drug design.Read moreRead less
