Summary
This project will identify factors within the bone marrow that regulate blood and immune cell formation. These include oxygenation and novel proteins identified in the applicant’s laboratory. How these factors from the bone marrow influence the behaviour of normal blood forming cells (called haematopoietic stem cells), and the progression of leukaemia and the response of leukaemia to chemotherapy treatments will be investigated. New drugs that interfere with these new factors will be tested for ....This project will identify factors within the bone marrow that regulate blood and immune cell formation.

Assessment Of The Properties Of Mesenchymal Stem Cells And Their Role In Skeletal Tissue Repair And Disease

Summary
There is currently a steady increase in surgical intervention and rehabilitation therapy for bone related fractures due to trauma or osteoporosis as a consequence of an aging population. Bone regeneration involves the coordinated participation of skeletal precursor cells, blood vessels and immune cells recruited from the surrounding tissues. This proposal examines the mechanisms mediating the maintenance and recruitment of skeletal precursor cells to sites of bone damage.
Stem Cell Niches: Biology And Therapeutic Applications

Funding Amount
$640,210.00
Summary
This research aims to identify how stem cells are regulated in the body in order to improve therapies for blood disorders and abnormal bone formation after severe traumas. Targeting molecules that deregulate stem cells will lead to improved treatments for diseases with outcomes including improved treatments for blood stem cell transplantation, improved therapy in cancer patients and reduced complications of spinal cord injuries.
Research Fellowship: Immunoregulation And Immunity To Viral Infection

Summary
Award of this fellowship will ensure the continuation of a highly productive research program that over the last 15 years has made numerous seminal contributions to understanding the immune responses generated during viral infection. This multidisciplinary, highly collaborative program seeks to use this knowledge to develop effective therapies, both cellular and gene therapy-based, to treat viral infections and their complications by harnessing the immune system.
My work focuses on cells of the immune system that act as sentinels on the lookout for invading pathogens and danger. These cells are called dendritic cells. I am particularly interested in understanding how these cells function within the bone marrow environment and how they may sense viral infection or cancerous cells within this tissue. We aim to understand their function in specific diseases including Lupus and in pre-leukemia conditions, and also in infectious and parasitic diseases.
The transplantation of healthy stem cells from a donor into a recipient with blood cancer (stem cell transplantation) is the most effective curative therapy for the majority of patients. Unfortunately this process results in unwanted, often fatal, side effects including infection, a rejection process known as graft-versus-host disease and in some patients, the leukaemia still recurs. This research will refine new treatments focused on overcoming these limitations and improving transplant outcome
I am a hematologist with expertise in the science of immunology and clinical experience in bone marrow transplantation and the treatment of hematological malignancies. My vision is to study the biology of dendritic cells, which are the specialized white cells that initiate the immune response, and then, to apply this knowledge to the design and introduction of novel diagnostic and therapeutic immune strategies, to improve the survival of patients with leukemia, lymphoma and multiple myeloma.
The Central Role Of The Osteocyte In Skeletal Pathophysiology

Summary
Bone diseases affect more people than any other group, carry a huge and growing socioeconomic cost, yet their aetiologies are not fully determined. This study will elucidate the role of the resident bone cell, the osteocyte, in prevalent bone diseases such as osteoporosis, osteoarthritis and related orthopaedic conditions, rheumatoid arthritis, bone cancer, and in systemic metabolism. The goal is to provide the knowledge and mechanisms for developing improved treatments and patient outcomes.
Bone Growth For Healthy Development: Physiology, Pathophysiology, And Regeneration

Summary
Musculoskeletal damage is a major burden on individuals and our health care system. My research program will focus on improving bone health in three important areas: (1) children’s growth plate injury and growth defects; (2) bone loss and bone marrow defects from cancer chemotherapy; (3) ensuring that bone grows healthily in early life. The overall intent of this research is to develop new therapies when bone doesn’t grow well, or is damaged.
