By 2066 this number is estimated to reach 20.4 million. These rates follow the overall worldwide ageing trend in which the global population aged 60 years is projected to reach nearly 2100 million. We are living longer than at any time in human history, but at the cost of developing a plethora of age-associated conditions for which we have no cure. I want to combat age-onset disease by targeting one of its main molecular mechanism: cellular senescence. My research program aims to dissect the effects of senescence in disease and regeneration, to improve the quality of life and promote greater ‘health span’ for the next generation. Research Overview Senescence and Regeneration Senescent cells accumulate in aged skin and other epithelia, increasing inflammation and promoting tissue damage. In skin, the inevitable consequence of ageing is that older skin becomes less efficient at repair and is more susceptible to damage and disease. This reality of ageing has been documented since World War I, with the observation that wounds heal more slowly in older soldiers whereas the fetus heals cutaneous wounds without a scar. We aim to understand where senescence starts, how it starts, and what interventions are the most suitable to improve skin regeneration during ageing. Identifying novel targets to accelerate regeneration: The African spiny mouse can shed up to 60% of their back skin to avoid predation. However, unlike other mammals, the spiny mouse can regrow the skin, muscle, cartilage and even hair, with minimal signs of fibrosis, making this a unique and valuable model to understand non-scarring regeneration. We aim to understand which pathways are responsible for this fibrosis-free healing and apply the results to improve regeneration in humans. Diagnostics for senescence Defining WHEN to target a condition is equally as important as the treatment itself. We aim to detect senescence biosignatures, to determine the best interventions and therapeutic window of opportunity.
