About the Project
The circadian clock is a biological timer which allows organisms to align their physiology with the 24h environment generated by Earth rotating on its axis. This internal clock regulates many aspects of physiology including sleep-wake cycles, feeding behaviour, hormone secretion, metabolism and immunity. My group is interested in addressing how the circadian clock regulates immunity. Most cells of the immune system possess intrinsic clockwork machinery which allows them to “keep time”. In addition, these cells respond to rhythmic extrinsic signals such as hormones and alter their function in response to daily changes in circulating levels. Work in this group addresses how the clock is involved in the pathogenesis of chronic inflammatory disease. For example, patients with Rheumatoid arthritis often report enhanced joint pain and stiffness in the early morning. This correlates with increased levels of circulating pro-inflammatory cytokines. Using mouse models of chronic inflammatory disease, we assess how sites of inflammation change over the course of a day, and address mechanisms underpinning these changes.
