Summary
Chronic inflammatory lung diseases like asthma and smokers lung are treated with combinations of anti-inflammatory drugs. Powerful anti-inflammatory types of steroid drugs are used in more severe disease. Even these powerful drugs are sometimes not effective enough. Our work is developing an understanding of how inflammation limits the anti-inflammatory effects of steroids and we are devising ways to overcome this with new drugs.

Summary
This project investigates endogenous chemicals that affect cells important for detecting and responding to pain. We aim to discover how these compounds affect proteins important for nerve cell function, particularly proteins that have a prominent role in detecting and transmitting painful events. The compounds we examine are not themselves likely to be drugs, but future therapies may involve manipulating the levels of these chemicals in the body, or using drugs that mimic the activity of these c ....This project investigates endogenous chemicals that affect cells important for detecting and responding to pain.

Summary
G protein-coupled receptors (GPCRs) are proteins that exist on every human cell, where they sense, and respond to environmental stimuli. Because of their importance they are targeted by drugs to treat many diseases. However little is known about the molecular steps that underlie cellular responses upon drug binding and this has hindered new drug development. This project uses new technology to determine the complex pathway of GPCR activation upon drug binding which will aid new drug development.
G Protein-Coupled Receptors (GPCRs) form the largest family of receptors and drug targets in living organisms. Currently, the major reason that new drugs fail to reach the clinic is lack of appropriate drug effect (approx. 30%). Thus, we need a better understanding of how GPCRs work and how this relates to disease. Work within my fellowship will address this knowledge gap, using GPCR models that are relevant to treatment of metabolic, inflammatory, cardiovascular and central nervous system disea ....G Protein-Coupled Receptors (GPCRs) form the largest family of receptors and drug targets in living organisms.

Summary
The peptide hormone relaxin is currently in a Phase III trial for the treatment of heart failure. However the peptide is not a good drug as it can't be taken orally and is very expensive to produce. We will study the interaction of relaxin with its cell surface receptor and the mechanisms by which the receptor functions. The knowledge gained will aid in the design of smaller, more potent and orally active forms of relaxin for the treatment of heart failure
Resolving And Targeting The Complex Molecular Mechanisms Underlying GPCR Signalling

Summary
Receptors are located on the surface of all human cells to allow our cells to respond to their environment. Over 30% of prescription drugs act through particular receptors called GPCRs, however effective drugs without side effects are difficult to develop because we do not have a deep understanding of how GPCRs transmit complex signals. In this proposal we seek to resolve the atomic-level details of GPCR signalling to assist in the development of better drugs for a diverse range of diseases.
