Can parasites cause host population divergence? . Parasites have been proposed to be drivers of population divergence, and ultimately speciation, yet the dynamics of this process are not well understood. This project will utilise new genomic techniques, novel hybrid zone analyses, and data on mate choice, to investigate the hypothesis that parasites drive population divergence through an interaction with immune response genes in the sleepy lizard Tiliqua rugosa.

Parasites have been proposed to be drivers of population divergence, and ultimately speciation, yet the dynamics of this process are not well understood. This project will utilise new genomic techniques, novel hybrid zone analyses, and data on mate choice, to investigate the hypothesis that parasites drive population divergence through an interaction with immune response genes in the sleepy lizard Tiliqua rugosa. This species provides an unprecedented system, backed by 37 years of long term host-parasite and behavioural data, and recent genetic analyses. This project intends to produce significant data to allow an examination of the early stages of host-parasite evolution in action, providing novel insights into the speciation process.

Human Leukocyte Antigen-A and -B regulation of Natural Killer cell function. The aim of this project is to determine how genetic variation in the genes encoding cell surface receptors expressed by innate lymphocytes and the molecules they recognise diversifies their capacity to sense and respond to infection. This knowledge is critical for understanding why there are intrinsic differences between individuals with respect to their capacity to respond to different types of infection and will ultim ....Human Leukocyte Antigen-A and -B regulation of Natural Killer cell function.

This knowledge is critical for understanding why there are intrinsic differences between individuals with respect to their capacity to respond to different types of infection and will ultimately inform our capacity to better deploy personalised medicines.Read moreRead less
Improving and manipulating the immune adjuvant properties of recombinant fowlpox vectors. Unbalanced immune responses may cause or worsen common and important diseases such as infections, allergies, cancers and autoimmunity. Interleukin-4 (IL-4) is the only immune active product or cytokine that safely skews an aberrant immune response to a healing type of response. Fowlpox viruses (FPV) provide safe and effective human vaccines. Engineering FPV to make both a relevant antigen and a cytokine is ....Improving and manipulating the immune adjuvant properties of recombinant fowlpox vectors. Unbalanced immune responses may cause or worsen common and important diseases such as infections, allergies, cancers and autoimmunity. Interleukin-4 (IL-4) is the only immune active product or cytokine that safely skews an aberrant immune response to a healing type of response. Fowlpox viruses (FPV) provide safe and effective human vaccines. Engineering FPV to make both a relevant antigen and a cytokine is proprietary technology. With our commercial partner and using experimental mice, we will test the concept that FPV making a model antigen and IL-4 initiate and/or maintain beneficial Type 2 responses. A successful outcome will guide clinical FPV-based vaccine development for the treatment of important human and veterinary diseases.Read moreRead less
Immunisation to protect against transmissible cancers in Tasmanian devils. This project aims to identify the immune escape mechanisms that the transmissible cancers, Devil Facial Tumour Disease (DFTD) use to avoid being killed by the immune system. Since the discovery of the second transmissible cancer (DFT2) mystery surrounds whether the devils immune system can respond to this cancer, hence this project will investigate the immune response to DFT2. The final aims are to develop a vaccine with ....Immunisation to protect against transmissible cancers in Tasmanian devils.

Since the discovery of the second transmissible cancer (DFT2) mystery surrounds whether the devils immune system can respond to this cancer, hence this project will investigate the immune response to DFT2. The final aims are to develop a vaccine with the potential to protect healthy devils and cure devils with DFTD.Read moreRead less
Pair bonding: is it all in the brain? This project aims to understand the interaction between classic pair bonding neural circuits, parasites, and the immune system in sleepy lizards. Social bonds are a cornerstone of human societies, especially true of the pair bond and this project expects to generate knowledge to help understand why healthy adult pair bonds are the single best predictor of longevity in humans. The expected outcomes of this project are to reveal the mechanistic basis of pair b ....Pair bonding: is it all in the brain? This project aims to understand the interaction between classic pair bonding neural circuits, parasites, and the immune system in sleepy lizards. Social bonds are a cornerstone of human societies, especially true of the pair bond and this project expects to generate knowledge to help understand why healthy adult pair bonds are the single best predictor of longevity in humans. The expected outcomes of this project are to reveal the mechanistic basis of pair bonding by identifying the brain regions, cell types and neurochemicals that promote pair bonding behaviour — for the first time in a wild animal. This project should provide significant benefits by increasing our knowledge of how pair bonds promote wellness.Read moreRead less
Investigating the evolution of innate and adaptive cellular immunity. This proposal aims to assess the impact of geographical and genetic isolation of the Australian Indigenous population on adaptive and innate immune systems. The project will use novel DNA sequencing approaches to generate the high resolution sequences of two genetic loci that regulate innate and adaptive immune responses, the major histocompatibility complex locus and the killer cell immunoglobulin-like receptor locus. In an i ....Investigating the evolution of innate and adaptive cellular immunity. This proposal aims to assess the impact of geographical and genetic isolation of the Australian Indigenous population on adaptive and innate immune systems. The project will use novel DNA sequencing approaches to generate the high resolution sequences of two genetic loci that regulate innate and adaptive immune responses, the major histocompatibility complex locus and the killer cell immunoglobulin-like receptor locus. In an initial screen, distinct variants and combinations of these genes were identified. This project aims to interrogate how variation in these critical genes impacts on the function of cytotoxic lymphocytes, providing insights into the evolutionary drivers of immune recognition mechanisms.Read moreRead less

Multi-photon imaging for infection, immunity, and self recognition. This proposal will address a gap in our imaging capabilities, allowing us to visualise the movement of immune cells and infectious agents such as bacteria and viruses within living tissues. This will immensely improve our capacity to understand interactions between the immune system, invading organisms and the rest of our body.

This proposal will address a gap in our imaging capabilities, allowing us to visualise the movement of immune cells and infectious agents such as bacteria and viruses within living tissues. This will immensely improve our capacity to understand interactions between the immune system, invading organisms and the rest of our body. The intravital imaging system will provide novel insights into how the immune system works, which will benefit the design of vaccines, the treatment of cancer, and our understanding of allergy. This state-of-the-art facility will also provide vital training in an emerging technology that will have application in many areas of biology.

Summary
Reproductive and pregnancy disorders are common in Australian men and women, with 6% couples seeking infertility services and another 30% experiencing recurrent miscarriage, preeclampsia or preterm birth, often resulting in life-time health problems for children, and sometimes stillbirth. This research will investigate the immune causes of these conditions, and the results will contribute to new health tools, diagnostics and medical treatments to support maternal and infant health.

Molecular genetic adaptive processes in natural co-evolution between rabbits and the rabbit haemorrhagic disease virus. This project will use extensive sampling and long-term field data to reveal ongoing co-evolutionary mechanisms behind the increasing resistance of pest Australian wild rabbits against a viral pathogen. The results will increase the understanding of evolutionary mechanisms in nature and will provide basic information for biological pest control of rabbits.
