Antigen-presenting cells control immune responses. Different types of these cells do different jobs and affect different diseases. We wish to control these processes by determining how the cells live and die. In particular we are interested in controlling the local immune responses during rejection of islet transplantation, which can cure type 1 diabetes.

Summary
This immune system provides our body’s defense against invading organisms like viruses, preventing disease and maintaining health. Immunity involves the interaction of several different cell types that together form arsenals tailored to combat each different infection. Professor Heath will investigate how cells of the immune system orchestrate effective immune responses to viral infections and malaria. He will use this understanding to design novel approaches to vaccination.
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.

Summary
José Villadangos studies the cells and molecules involved in Antigen Presentation. This phenomenon consists of the detection, capture and display of microbe fragments on the surface of Antigen Presenting Cells (APC) for recognition by T cells. This initiates an immune response that culminates in the deployment of cells and molecules armed to fight the infection. His research may lead to development of more effective vaccines and prevention of autoimmunity, allergy and transplant rejection.

Summary
The focus on our research is to understand how the immune system responds to viral challenges and how viruses attempt to counteract immune responses. We focus on systemic disease, as well as disease that involve the eye. Understanding how immune responses are regulated will allows us to develop improved therapies
I am an cellular immunologist determining the mechanisms by which immunity to foreign organisms is generated, how tolerance to self tissues is maintained, and how the immune system iscriminates between foreign organisms and self.
This application seeks information on the factors controlling T cell survival, tolerance and responsiveness to foreign antigens and tumour antigens. Particular attention will be directed to determining how T cells are kept alive through contact with self ligands and cytokines while preserving self tolerance and how anti-tumour responses can improved without augmenting the function of T regulatory cells.

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.

Summary
The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host. Individuals with primary immunodeficiencies have defects in the development and/or function of the cells of their immune system and are more susceptible to infectious diseases. This study will investigate such individuals to identify functions for specific genes and immune cells in order to understand the requirements for generating effective immune responses ....The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host.

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.
