Research Profile

The research focus of our laboratory is investigating the interactions between the peripheral immune system, and brain mechanisms regulating sickness responses to systemic inflammation. In particular we are interested in the role of the immune mediators cytokines and more recently adipokines such as the appetite regulating peptide leptin. The work on adipokines in particular has led us to explore the link between the energy status of an individual and their ability to mount an immune response to pathogens. This work involves using models of food deprivation and obesity as a way of regulating some of the peptides of interest by using physiological as opposed to pharmacological interventions.
