CIRCADIAGEING text with three circles representing abstract clock faces

Clock excitability, circadian rhythms and healthy ageing

The CircadiAgeing project explores how disruptions in circadian rhythms, the natural 24-hour cycles of physiological and behavioural patterns, contribute to ageing and related health issues.

Our researchMeet the team

Circadian rhythms become weaker as we age leading to poorer sleep and contributing to diseases such as Alzheimer’s disease. This BBSRC strategic larger and longer grant marks a major investment of UKRI supporting researchers at Bristol, Exeter, Imperial, Kings and Manchester to investigate exactly how ageing affects circadian rhythms.

Focusing on both the well-known molecular aspects and the less understood membrane-based mechanisms that reflect daily changes in cell excitability, this crucial project aims to uncover how these clocks weaken synergistically with age, impacting our overall health.

Using interdisciplinary methods including cutting-edge genetic analysis and computational biology, the research team hopes to develop interventions that could restore the robustness of these biological clocks, promoting healthier ageing and potentially reducing age-related disorders.
