Summary
To meet the challenges of life, a human being requires 30 trillion cells, a blue whale a staggering 100 quadrillion. This vast diversity of cells derives from very few unspecialised cells that can become any cell type of the adult body - the pluripotent stem cells. We will use innovative imaging techniques to uncover the cellular architecture of pluripotency to provide critical insights into how the various parts of a versatile cell, its cytoskeleton and organelles, are assembled in real-time.
Modulating The Skin Immune System With Physical Stimulus

Summary
The Fellowship will be based between Uni QLD and Massachusetts General Hospital, Harvard Medical School. It will consist of pre-clinical development and validation of an in vivo optical micro-manipulation system for laser-guided extraction of cells. A comparable system will then be developed for characterization of leukocytes in healthy and diseased human skin. The long term outcomes will be better characterisation of inflammatory skin disease resulting in new targets and therapeutic strategies.
Mechanotransduction is defined as the ability of living cells to respond to and convert mechanical stimuli into electro-chemical cellular signals to ensure survival. It is largely dependent on membrane proteins known as mechanosensitive (MS) ion channels. These channels are involved in senses of hearing and touch, and are also crucial regulators of heart and muscle function. This research aims to elucidate the general physical principles underlying mechanotransduction in living cells.
The rapid interactions of circulating human blood platelets is critical to prevent bleeding, but can cause thrombotic diseases (heart attack, stroke). These highly regulated interactions involve specific adhesive proteins. Our studies will define factors regulating platelet interactions. Imaging the thrombotic process will quantify platelet function at an unprecedented resolution and we have a panel of new candidate reagents that will be assessed for antithrombotic potential.
Unraveling the variability in the protein expression in tissues or cell populations is critical to understand how cells respond to their environment. For example, this can provide details about the cellular response to an infection or to a chemoterapic. As of today, single cell protein analyses has become at reach, but its application is still cumbersome and its throughput is low. This proposal aims to develop and deploy a simple and robust method to analyse the protein content in single cells.

Is Leaky Gut A Precursor To Inflammatory Bowel Disease?

Summary
Inflammatory Bowel Diseases (IBD) are chronic idiopathic diseases, characterised by episodes of relapse and remission of intestinal inflammation. Whilst the exact cause remains unknown, there is mounting evidence that a defect exists in the gut lining protecting the body in patients who develop IBD allowing bacterial antigens to enter the body. We aim to use novel imaging combined with colonoscopy called confocal endomicroscopy to image the bowel lining at high power to demonstrate this defect.
