Ataxia-Telangiectasia: An Emerging Role For Inflammation In Driving Neurodegeneration And Premature Ageing

Summary
Ataxia-Telangiectasia (A-T) is a devastating genetic disease that arises in early childhood and causes patients to die in their twenties. To date there is no cure, and therapeutics are desperately needed. This project will use state-of-the-art brain organoids derived from stem cells of A-T patients in order to better understand this disease and evaluate novel drugs that target the molecular mechanisms that drive chronic inflammation and brain neurodegeneration in children with A-T.
Understanding The Molecular Mechanisms Of Cell Death In Radiotherapy

Summary
Radiotherapy (RT) is responsible for 40% of cancer cures. New technology enables RT delivery in fewer treatments using higher radiation dosages through a technique called 'ART'. While ART is effective in the clinic, the underlying mechanisms of cancer cell death are unclear. Here we show that ART induces two distinct waves of cancer cell death. We will characterize these waves of cell death and determine how to enhance tumour cell killing with pharmacological intervention.
Identification Of Novel Mediators Of Bone Catch-up Growth

Summary
Musculoskeletal growth disorders cause significant suffering in children and impair new workforce generations before their working life starts. Despite this relevance, non-invasive methods to induce growth recovery of impaired bones are an unmet need, as we lack sufficient understanding of how this process works. To address this knowledge gap, we generated mouse models that will allow us to reveal foetal mediators of compensatory growth that could be reactivated postnatally to boost bone growth.
Epigenetic Reprogramming Of Calcified Vascular Smooth Muscle Cells As A Treatment For Vascular Calcification

Summary
Pathological hardening of blood vessels, or vascular calcification, is a frequent and deadly complication of many cardiovascular disorders. It is caused by the irreversible change in mature vascular smooth muscle cells (the main cell type in the blood vessel walls) to a bone-forming cell type. We have now identified a new gene that can potentially revert calcified vascular cells back to their physiological state. This represents a promising new approach for treatment of vascular calcification.
Harnessing Macrophage-derived Cytokine Signalling In Skeletal Muscle Regeneration

Funding Amount

Summary
We propose to develop novel therapies and tissue engineering approaches for the treatment of muscle injury and wasting disorders using specific muscle stem cells called satellite cells. Our ultimate aim is to accelerate the development of safe, effective and affordable muscle stem cell-based therapies, in an attempt to lessen the disease burden of muscle wasting disorders. The approach will make use of the novel stem cell activating compounds and immune cells that we have identified.
