Constructing an embryo. This project investigates the cellular and molecular mechanisms underlying temporal and spatial organisation in the eutherian preimplantation embryo. It will examine: the relative roles of cell cycle and circadian clocks in developmental timing; the molecular mechanism by which intercellular adhesion patterns influence spatial organisation; the extent to which marsupials use similar timing and spatial localisation mechanisms to eutherians; the impact of in-vitro manipulat ....Constructing an embryo. This project investigates the cellular and molecular mechanisms underlying temporal and spatial organisation in the eutherian preimplantation embryo. It will examine: the relative roles of cell cycle and circadian clocks in developmental timing; the molecular mechanism by which intercellular adhesion patterns influence spatial organisation; the extent to which marsupials use similar timing and spatial localisation mechanisms to eutherians; the impact of in-vitro manipulations over the first 5 days of mouse pregnancy on embryonic temporal and spatial organisation.Read moreRead less
Understanding the potency and role of individual stem cells in the skin using Rainbow technology. To renew itself, the skin and its components rely on the activity of stem cells. This project will define more precisely the role of each individual stem cell by labelling them with a unique colour and following its fate. This project has the potential to change our current view on how the skin maintains and repairs itself.
Enhancing neurogenesis in the adult primate brain. New neurons are robustly generated in the subependymal zone (SEZ) during human development. Thus, the SEZ may represent an endogenous modifiable source of neurons to enhance plasticity and therapeutic potential in the brain. However, despite our preliminary data, SEZ neurogenesis beyond the first months of life is controversial. This project aims to understand changes in the capacity for human SEZ proliferation from birth through to ageing and w ....Enhancing neurogenesis in the adult primate brain. New neurons are robustly generated in the subependymal zone (SEZ) during human development. Thus, the SEZ may represent an endogenous modifiable source of neurons to enhance plasticity and therapeutic potential in the brain. However, despite our preliminary data, SEZ neurogenesis beyond the first months of life is controversial. This project aims to understand changes in the capacity for human SEZ proliferation from birth through to ageing and whether neurogenesis may be induced by inflammation in the adult. Using transcriptomics we will also determine how the neurogenic environment changes with age/inflammation. This project is an important step in proving that the brain's potential to generate new neurons extends beyond infancy.Read moreRead less

The structure of heteromeric amyloid fibrils with signaling activity. This project aims to determine the composition, structure and properties of important protein complexes involved in a newly identified cell death pathway known as necroptosis. This cell death pathway removes unwanted or damaged cells during development or infection. These necroptosis protein complexes are unusual because they have a fibrillar amyloid structure, contain more than one protein type in the fibrils and have a funct ....The structure of heteromeric amyloid fibrils with signaling activity. This project aims to determine the composition, structure and properties of important protein complexes involved in a newly identified cell death pathway known as necroptosis. This cell death pathway removes unwanted or damaged cells during development or infection. These necroptosis protein complexes are unusual because they have a fibrillar amyloid structure, contain more than one protein type in the fibrils and have a functional, signalling role. The research will determine how these fibrils form and how the structures confers biological function. It could identify features in these fibrils that can be targeted as a means of ultimately preventing tissue damage after heart attack and stroke.Read moreRead less
Inhibiting protein-protein interactions involved in neural development and disease. This project will determine the molecular mechanisms by which the protein LMO4 (a regulator of brain development) binds to DEAF1 (which also regulates neural development) and CtIP (which protects against tumour formation). This will allow a set of reagents to be developed to help determine the functions of LMO4, and may ultimately be used to treat disease.
Links between DNA replication and chromosome end maintenance. This project aims to increase knowledge of the way in which cells maintain their genomes, including the ends of their chromosomes, to enable their own survival. The ends of chromosomes (telomeres) are essential for survival and proliferation of the cells of most organisms. This project aims to determine the molecular details of a recently discovered link between telomere maintenance and the way cells maintain the integrity of their ge ....Links between DNA replication and chromosome end maintenance. This project aims to increase knowledge of the way in which cells maintain their genomes, including the ends of their chromosomes, to enable their own survival. The ends of chromosomes (telomeres) are essential for survival and proliferation of the cells of most organisms. This project aims to determine the molecular details of a recently discovered link between telomere maintenance and the way cells maintain the integrity of their genome. This is likely to lead to increased understanding of the fundamental biological process of genome maintenance, representing a significant scientific advance. The project expects to have far-reaching implications for biotechnology applications that require the survival of cells.Read moreRead less

Dissecting a hematopietic transcription factor complex. The development of mature active cells is a highly complex and coordinated process that is controlled largely by groups of interacting regulatory proteins. We are trying to understand, at a very detailed level, how a specific group of these proteins interact to regulate both normal blood cell development and the onset of childhood leukemias. Using this information we will try to develop reagents that can be used to inhibit these interaction ....Dissecting a hematopietic transcription factor complex.

We are trying to understand, at a very detailed level, how a specific group of these proteins interact to regulate both normal blood cell development and the onset of childhood leukemias. Using this information we will try to develop reagents that can be used to inhibit these interactions and be used as lead compounds for treatments for disease.Read moreRead less
Mapping networks governing cell state plasticity: how, where and when? Single cell organisms are the basic unit of life, yet, if they had not developed the ability to change cell states we would not exist today. Changing cell states lies at the core of almost every developmental and disease process in multicellular organisms. Building upon our fundamental discovery that stem cells and non-stem cells readily interconvert, we will now incorporate innovative cell systems and the development of our ....Mapping networks governing cell state plasticity: how, where and when?
