Prof Carbone’s laboratory specialises in the study of immunity at the body surfaces. These surfaces include skin and mucosal tissues such as respiratory and gastrointestinal tract, all of which are the common points of entry for a variety of infectious agents. He has found that there exist cells at these peripheral sites that are separate from the immune components that one finds in the blood and, more importantly, that provide a profound level of protection during new infection.

He now propose to determine how best to induce this type of peripheral immune protection and how one can exploit these mechanisms for the purpose of infection control.Read moreRead less
The immune system is the essential complex barrier that protects the organism for infections and some malignancies. Despite considerable efforts, the mechanism by which immune cells kill dangerous unwanted cells is poorly understood. This project will investigate the mechanism of action and the role in human pathologies of a key component of the immune system, a toxic protein perforin.
Understanding The Key Attributes Of CD8 T Cell Receptor Transfer As An Antiviral Strategy And Harnessing The Process To Combat Persistent Viral Infections

Funding Amount
$612,885.00
Summary
We have recently discovered a new process through which the numbers of antiviral immune cells can rapidly expand, without dividing, to combat a virus infection that may otherwise be fatal. This represents a significant advance in our knowledge on how a speedy, virus-specific response can be mounted. We will study how this process can be applied to therapeutic strategies to overcome medically significant persistent viral infections.
Characterisation And Development Of Type-2 NKT Cells

Funding Amount
$853,885.00
Summary
Humans defend themselves from foreign pathogens by mounting a protective immune response. Type-2 NKT cells recognise foreign lipid molecules and play a key role in immunity. This project is designed to understand to how Type-2 NKT cells develop within the body, how they recognise lipid molecules and how they carry out their immune functions. This work will have important implications in understanding the role of NKT cells in human health and disease.
The Role Of Kdm1a In Epigenetic Regulation Of Virus-specific T Cell Differentiation.

Summary
Recovery from infection, or vaccination, results in the establishment of protective immunity that persists for the life of an individual. Unfortunately, our understanding of how protective immunity is established and maintained after infection or vaccination is lacking. This proposal will determine whether specific enzymes involved in rewriting the genetic blueprint are key for establishing and maintaining this protective capacity. Understanding these mechanisms has implications for vaccination ....Recovery from infection, or vaccination, results in the establishment of protective immunity that persists for the life of an individual. Unfortunately, our understanding of how protective immunity is established and maintained after infection or vaccination is lacking. This proposal will determine whether specific enzymes involved in rewriting the genetic blueprint are key for establishing and maintaining this protective capacity. Understanding these mechanisms has implications for vaccination and improved immunotherapy strategies for cancer.Read moreRead less
The Impact Of Obesity On Immunological Tolerance Of The Fetus

Summary
Obesity increases the risk of miscarriage during pregnancy. The reasons for this are not known, although it is thought that abnormal levels of hormones and metabolic parameters are a contributing factor. We hypothesise that the immune system plays a role. In this project we will determine if obesity upsets the fine-tuning of the immune system that is crucial for successful pregnancy. Understanding the reason behind adverse pregnancy outcome will allow appropriate management of maternal obesity.
NKT cells are a type of lymphocyte with the ability to prevent a broad range of diseases including cancer, autoimmunity, infection and graft rejection. Sometimes, NKT cells also cause diseases, including allergy and atherosclerosis. This project will investigate how NKT cells become activated in these diseases by studying their surface receptors and what these receptors interact with.
Recognition Of Lipid Antigens By CD1d-restricted Type-2 NKT Cells

Funding Amount
$417,684.00
Summary
Protection against infection depends on T cells, which recognise and target foreign molecules called antigens via a specialized antigen receptor known as a T cell receptor (TCR). This project focuses on a specialised population of T cells called Natural Killer T (NKT) cells that recognise lipid antigens. The work outlined in this grant will increase our understanding of how different TCRs can recognise diverse lipid antigens thus providing insight into the role of NKT cells in the immune system.
Mapping The Molecular Blueprint For Immune Cell Differentitation

Summary
Killer T cells are white blood cells that are key for helping control virus infections and in the recognition and elimination of cells that have become cancerous. This proposal aims to identify novel molecular mechanisms that control the ability of killer T cells to mediate their antiviral and anti-cancer functions. This will provide molecular targets for possible clinical interventions designed to either promote immunity (vaccination) or limit damage caused by T cell responses that target self
Delineating Immune Circuits For Innate And Adaptive Immune Protection

Funding Amount
$876,005.00
Summary
The immune system provides the essential frame-work to protect us against infection, disease and to heal tissues after trauma. This is achieved by a complex but elegant network of different types of white blood cells. Understanding the molecular wiring of these cells will provides fundamental insights to how the body fights pathogen infections and cancer and lays the foundation to therapeutic approaches to vaccination and disease treatments.
