Project Description

Background: It is clear that inflammation underlies many important chronic disease states in both the central nervous system (CNS) e.g. multiple sclerosis and in the periphery e.g. modifying the pathogenesis of atherosclerosis and arthritis. My research group is interested in studying the endogenous pathways that regulate the magnitude and duration of the inflammatory response in order to discover new targets for the development of anti-inflammatory drugs.

Work leading up to the proposal: G protein-coupled receptors (GPCRs) play an important role in macrophage cell biology in disease processes including inflammatory cell recruitment and GPCRs are the target for many successful medicines. In recent work we identified a novel biased agonist at the immunometabolic receptor GPR84 (Lucy et al. 2019). We want to better understand the biology of other immunometabolic receptors by identifying novel chemical tool compounds and testing their effects on macrophages and microglia in inflammation.

Original hypothesis: We propose that novel small molecule agonists and cell metabolites active at immune-metabolic GPCRs will alter macrophage and microglial biological activity in inflammation. These biological activities such as chemotaxis, enhanced phagocytosis, changes in macrophage polarisation and secretion of cytokines could represent novel targets for the development of anti-inflammatory drugs.

Techniques to be used: The student will join a laboratory using a wide range of cell and molecular biology techniques with access to a wide range of pre-clinical models of human disease and a good track record in chemical biology and drug discovery and drug repositioning.
