The diversity of HIV quasispecies within a single AIDS patient is far greater than the global diversity of influeneza annually, highlighting the enormous burden HIV imposes on the immune network. The capacity of HIV-1 to evolve quickly has significantly impaired our effort to produce effective vaccine and long lasting treatment strategy. This project utilizes multidisciplinary approaches to delineate determinants that drives the diversification of HIV-1.
Clonal Evolution In Myelodysplasia And Acute Myeloid Leukaemia Following Azacitidine

Summary
The myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) represent a spectrum of clinically heterogeneous malignancies that remain incurable in the vast majority of patients. Whilst the DNA mutations underpinning the initiation/maintenance of these malignancies are largely known we have little insight into how these mutations alter response to therapy. Using a range of sophisticated cutting edge technologies we will study how these DNA mutations evolve over the course of treatment.
Identification Of Haematopoietic Stem And Progenitor Cell Subpopulations

Funding Amount
$873,525.00
Summary
We want to dissect the machinery underlying how each and every individual stem and progenitor cell generates the different blood cell types. We have at our disposal the latest molecular and computational technologies to do this. Knowledge gained from this project could be used for tissue engineering to make blood cells on demand for patients with immune deficiency, or alternatively to treat leukaemia patients where blood cells are overproduced.
Pathways To Extensive And Pan Antibiotic Resistance In The Globally Disseminated Acinetobacter Baumannii GC2 Clone

Funding Amount
$865,004.00
Summary
The project will study the evolution of a Acinetobacter baumannii clone that is found all around the world, and has become resistant to most or all of the currently available antibiotics. Resistance has been acquired in a series of steps, and the resistance genes present and the events involved will be used to understand the globalization process. The increased understanding of resistance development should assist in controlling untreatable infections and in preserving antibiotics.
Dendritic cells (DCs) are the body’s sentinels, with three specialized subtypes. They monitor for infections and cancer and then activate immune T cells to clear it. Interestingly, they can all arise from a single cell, but the precise steps are unknown. By literally filming this process and analyzing the movie, we hope to draw the ‘family trees’ that lead to their generation. This knowledge will offer crucial clues as to how to boost or reduce their numbers for medical applications.
Tracking Epidermal Clonal Evolution During Skin Cancer Induction And Progression

Funding Amount

Summary
Skin cancer is the most frequent form of cancer in Australia and in many parts of the world. It is strongly connected to ultraviolet radiation from the sun. In this project, we will use our capacity to track individual cells, to observe the heterogeneity of tumours and the lesions that precede them. We will show the importance of this heterogeneity in tumour progression unveiling the limits of current therapies against skin cancer.
Defining The Molecular Regulation Of Muscle Stem Cell Action During Organ Growth

Funding Amount
$738,259.00
Summary
How do organs grow to develop a complex cellular structure. Organ growth needs a careful balance between cell commitment and stem cell self renewal to maintain tissue growth trajectories. How this balance is achieved at the cellular and molecular level remains unresolved for most organ systems. This application studies a specific stem cell pool within the zebrafish myotome and how it is used to drive organ growth.
