An investigation into CD1a, a versatile antigen-presenting molecule. This project aims to investigate how T lymphocytes are activated by lipids presented by the skin-associated antigen-presenting molecule, CD1a. Using X-ray crystallography and cellular immunology, we will provide fundamental insight into this poorly understood immunological axis. We will determine the molecular basis for how CD1a presents diverse self and foreign lipids, and how such CD1a-lipid complexes are recognised by the r ....An investigation into CD1a, a versatile antigen-presenting molecule. This project aims to investigate how T lymphocytes are activated by lipids presented by the skin-associated antigen-presenting molecule, CD1a. Using X-ray crystallography and cellular immunology, we will provide fundamental insight into this poorly understood immunological axis. We will determine the molecular basis for how CD1a presents diverse self and foreign lipids, and how such CD1a-lipid complexes are recognised by the responding T cells. This basic science discovery project will provide substantial new knowledge in the burgeoning field of lipid-mediated immunity, which should ultimately lead to new therapies targeting the CD1a lipid display molecule to either prevent immune mediated damage or promote protective immunity as required.Read moreRead less
An investigation into the basis of the T-cell mediated adaptive immune response. Understanding the adaptive immune response to human pathogens is critically important to develop strategies to combat infection. This project will provide a better understanding of how T cells combat viral infection, and will lead to fundamental advances in our understanding of viral immunity and the development of novel immunotherapeutic strategies.

Funding Amount
$1,196,304.00
Summary
This project is focused on a type of T-cell, termed a MAIT cell, which is found abundantly in the lining of the gut. We are investigating how this MAIT cell is activated by riboflavin and folic acid metabolites. We are also examining how commonly prescribed drugs impact MAIT cells and how such activation may be linked to diseases, including inflammatory bowel disease.
Artificial Synthesis Of The Type III Secretion System Translocon. A New Approach To Vaccine Design

Summary
Today hospitals are plagued with bacterial infections that do not respond to antibiotics. The problem exists because although antibiotics are effective at killing bacteria, this paradoxically also helps the drug-resistant bacteria thrive. We will pioneer a completely new approach to vaccine design that allows us to construct a vaccine that protects us from bacterial infection without killing the bacteria. The vaccine should therefore be far less susceptible to drug resistance.
A molecular and functional investigation of innate-like T cells of the immune system. This project will investigate innate-like T cells, which are at a crossroad between innate and adaptive immunity. A complete knowledge of the cellular function and balance of these cells will offer potential for new immunotherapies associated with infectious and autoimmune disorders.
Drivers of effective T cell immunity. This project aims to investigate the mechanisms underpinning an effective immune response. In doing so, the project expects to decipher the various determinants of T cell immunity and explore how these determinants are integrated to generate effective immunity. The project will use a multidisciplinary approach to investigate antigen abundance and developmental, structural, and molecular aspects of T cells, expecting to significantly enhance our fundamental u ....Drivers of effective T cell immunity.

A Molecular Investigation Into Lipid-reactive Immunity To Combat Mycobacterium Tuberculosis Infection

Summary
Tuberculosis (TB) infection currently causes ~1.5 million deaths annually. Due to new survival features acquired by the causative agent (Mycobacterium tuberculosis), traditional TB drugs and vaccines are becoming inefficient. Mycobacterium tuberculosis has a protective lipid-dense cell wall that is targeted by our immune system. We aim to understand the mechanisms of the lipid-mediated immune response to TB in order to develop more effective strategies to combat this disease.

Summary
#ERROR: -Transmission and amplification of signals between subcellular compartments underpins cell function. Calcium ions are cellular messengers that can cross Membranes using specialised pores. CRAC Calcium channels in particular are critical for immune system function,and partner Proteins switch them on and off in a feedback response to compartmental Calcium levels. the objective of my research is to investigate how opening and closing of the CRAC pore is triggered at a molecular level.
Exploring therapeutic approaches to combat Coeliac Disease. In Coeliac disease the immune system reacts to ingested wheat protein and attacks the tissue of the small intestine. The wheat protein activates certain immune cells and this initiates a destructive inflammation. In collaboration with the Australian-based company Nexpep, this project aims to develop therapeutics against Coeliac disease.
