Summary
We have different types of infection-fighting white blood - the soliders of the immune system. They can all grow from a single stem cell like a seed grows into a tree. So, by understanding this complex process, new and better therapies for cancer, organ transplantation and infectious disease are constantly emerging. I aim to use a cutting-edge technology called ‘cellular barcoding’ to answer some of the age-old questions about how stem cells grow into white blood cells.

Summary
Graft versus host disease (GVHD) is a potentially fatal complication of bone marrow stem cell transplantation for leukaemia and lymphoma. In an animal model of GVHD, we have recently shown 100% effectiveness of treatment with a donor immune cell population, regulatory T cells. We will determine how this therapy works in the animal model. We will use a new technique, mass cytometry, to analyse patient blood samples in preparation for developing regulatory T cell therapy for GVHD.

Not all patients with leukemia will be cured by chemotherapy. Stem cell transplantation improves their chances of survival. Stem cell transplantation requires intensive chemotherapy and radiotherapy to eradicate the underlying disease and infusion of healthy stem cells to provide an anti-leukemic effect and normal blood cells.

Stem cell transplantation improves their chances of survival. Stem cell transplantation requires intensive chemotherapy and radiotherapy to eradicate the underlying disease and infusion of healthy stem cells to provide an anti-leukemic effect and normal blood cells. Recovery from transplantation is not straightforward. Recovery can be hampered by the immunological reaction of the donor cells against the patient (Graft versus Host Disease [GVHD]), despite immunosuppression. GVHD produces serious damage to the internal organs and lining of the mouth and gut. Recovery can also be circumvented by leukemic relapse. GVHD is associated with an increased risk of death and dying after transplantation. To date therapy for GVHD has relied on eliminating the T cells that cause the disease. However for T cells to cause damage they must first be primed with antigen presented on activated dendritic cells. The intensive conditioning therapy required to eradicate the underlying disease before transplantation also activates dendritic cells. Our project seeks to investigate the effects of lethal and non-lethal conditioning on dendritic cells with the aim of validating the use of antibodies designed to deplete activated dendritic cells as therapy for graft versus host disease.Read moreRead less

Summary
Bone Marrow transplants provide life saving therapy for leukaemias, lymphomas and other life threatening blood disorders. One of the major life threatening complications is acute graft versus host disease (AGVHD) in which the doner immune system damages the patient's skin, liver and gut, amongst other tissues. Dendritic cells initiate and direct immune responses. We have shown that dendritic cells are central to the initiation of AGVHD and have shown that a marker called CMRF-44 is expressed on ....Bone Marrow transplants provide life saving therapy for leukaemias, lymphomas and other life threatening blood disorders. One of the major life threatening complications is acute graft versus host disease (AGVHD) in which the doner immune system damages the patient's skin, liver and gut, amongst other tissues. Dendritic cells initiate and direct immune responses. We have shown that dendritic cells are central to the initiation of AGVHD and have shown that a marker called CMRF-44 is expressed on activated dendritic cells before AGVHD emerges. We have developed potential new therapeutic antibodies that target activated dendritic cells and shown that they are effective in preclinical studies. This project will further validate these antibodies, then test their safety and their ability to prevent AGVHD in patients. The trial will also test whether they have the expected additional beneficial effect of preserving protective anti-viral and anti leukaemic immune responses.Read moreRead less
