Summary
Adverse drug reactions are one of the leading causes of death in hospitalised patients. We have discovered a new mechanism that links these reactions to recognition of drug induced changes in immunological self, resulting from interactions of drugs with immune receptors. This project probes the generality of this mechanism by examining the basis of life threatening reactions to drugs used to treat epilepsy (carbamazepine), gout (allopurinol), HIV (Nevirapine) and towards aspirin a commonly used ....Adverse drug reactions are one of the leading causes of death in hospitalised patients.

Understanding The Complexity Of Antigen Presentation

Summary
I have developed and established the use of mass spectrometry to identify and quantitate ligands of antigen presenting molecules to understand the breadth of immune responses in a variety of human disease states including autoimmunity, cancer, infection and allergy. By embedding the technology in disease focussed research programs I will define the molecular bases of these diseases and the important immunological targets that will provide new avenues for therapeutic development and vaccines.
Investigation Of Small Molecule Interactions With The Human Leukocyte Antigen And Their Role In Non-infectious Disease

Summary
The Human Leukocyte Antigens (HLA) play a key role in the immune system helping the body differentiate healthy from diseased cells. Numerous autoimmune diseases and adverse drug reactions are associated with specific HLA variants. This study seeks to unlock the mechanisms behind these diseases, investigating how small molecules including drugs interact with the HLA to make healthy body cells seem foreign. This research has the potential to inform strategies for disease avoidance and management.
Antigen Presentation During HLA B27 Associated Auotimmune Disease

Funding Amount
$715,365.00
Summary
Ankylosing spondylitis is a debilitating arthritic disease, susceptibility to which is conferred by genes of the immune system, particularly HLA-B27, and following gastrointestinal infection. Using mass spectrometry we will identify bacterial peptides bound to HLA-B27 on infected cells that may trigger an autoimmune response. Defining the self peptides that remain the targets of autoimmunity will unravel the molecular and cellular mechanisms if disease and identify peptides for immunotherapy.
The Molecular Basis Of HLA-linked Drug Hypersensitivity

Summary
Adverse drug reactions are one of the leading causes of death in hospitalised patients. We discovered a new mechanism that links these reactions to recognition of drug induced changes in immunological self, resulting from interactions of drugs with immune receptors. This project continues to probe the mechanisms of immune mediated drug reactions by examining the basis of life threatening reactions to drugs used to treat epilepsy, gout and commonly used drugs such as penicillin and aspirin.
