Circadian-regulated physiological functions: how does your circadian clock help you fight disease?
Our laboratory aims to understand how specific circadian-regulated physiological functions contribute to health and disease using Drosophila melanogaster. Circadian rhythm, or the oscillation of biological functions over the 24 hour day, is increasingly recognized as an important factor in human health. Many diseases have a circadian component, particularly inflammatory diseases. For example, you are most likely to have a heart attack at 8 am, flares of rheumatoid arthritis at 6 am, and an asthma attack at 4 am. Moreover, many diseases (bacterial infeciton, Alzheimer's, Parkinson's, Huntington's, bipolar disease, schizophrenia, epilepsy, breast cancer, aging) are associated with loss of circadian regulation. How does loss of circadian regulation accelerate or delay the progression of disease? We found that, in the fly, circadian mutants are immunocompromised against bacterial pathogens and that the immunity of wild-type flies oscillates with circadian rhythm: flies have different survival times depending on the time of day that they are infected. We now have three major foci for our research: innate immune cell function; metabolism; and sleep. Our overarching goal is to use circadian biology as a prism to understand the interaction, coordination, and regulation of complex physiologies in the whole animal that contribute to disease pathology.
