Multistage Vaccines For The Prevention Of Tuberculosis

Summary
Almost two million people die from tuberculosis (TB) each year. The current vaccine, BCG, is ineffective at controlling TB and the type of immune response needed to protect against the disease is poorly understood. We have discovered new antigens of the TB bacterium, and we will combine them with novel delivery strategies to develop new TB vaccines. We will also determine the type of immune response needed to protect against TB, which will aid progression of vaccines into clinical trials.
The Impact Of The Neonatal Gut Microbiome On Specific And Nonspecific Vaccine Responses.

Summary
Humans are colonised by a large and diverse group of microorganisms, collectively known as the microbiome. The gut microbiome, in particular, hosts an enormous abundance and diversity of bacteria, which perform a range of essential beneficial functions. Our study will investigate whether disruption of the gut microbiome in newborns, for example through antibiotic usage or maternal diet, leads to an impairment of subsequent immune responses to childhood immunisations.
Immunomodulatory Vaccines In The Treatment Of Peanut Allergy

Summary
Peanut allergy is the most common cause of food-induced anaphylactic reactions in Australia and is a major burden to our healthcare system. Current clinical practice advice dietary avoidance to prevent fatal anaphylactic responses. We propose the use of an immunomodulatory vaccine to re-write the immune response to peanut antigens, from an allergic to a tolerant phenotype. This study will provide novel insights into rational approaches for manipulating immune memory to food allergens.
Tapasin And Major Histocompatibility Complex Class I Antigen Presentation

Summary
An effective T cell response (cellular immune response) to infections is vital to a functional immune system. Normally, proteins are cleaved into small molecules called peptides and these peptides are in turn presented by Major Histocompatibility Complex molecules to T cells. However, we have only partial understanding of what determines the choice of peptides that are finally presented to T cells. Recent research suggests that a molecule called tapasin may also influence the choice of peptides. ....An effective T cell response (cellular immune response) to infections is vital to a functional immune system.

However, we have only partial understanding of what determines the choice of peptides that are finally presented to T cells. Recent research suggests that a molecule called tapasin may also influence the choice of peptides. This research proposal aims to examine the role of tapasin in this regard. A thorough understanding of the basic principles of peptide presentation to T cells is crucial to the design of effective vaccines. Furthermore it will also broaden our understanding of immunological responses to cancer, autoimmune diseases and infections.Read moreRead less
