Transplant Immunology

Stem cell transplantation is considered the “gold standard” procedure for the treatment of blood cancers (including leukaemia, lymphoma and myeloma) in both adults and children. Globally, over 9,000 patients per year undergo this high-risk, life-saving therapy. However, graft-versus-host disease (GVHD) occurs in 50-70% of patients, of which 20% will develop severe GVHD that is untreatable. Unfortunately, additional complications such as infection and cancer relapse are common.

Research conducted by the Transplantation Immunology laboratory focuses on improving our understanding of the pathophysiology of complications following stem cell transplantation. Using unique preclinical models combined with innovative technologies, the group aims to define the immunological mechanisms that underpin these complex disease processes, with the view of translating the basic research findings into clinical practice.

CURRENT RESEARCH

  • cytokine responses within the gastrointestinal tract which dictate T cell fate and transplant outcome
  • interplay between cytokines, microbiota and metabolites which regulate acute intestinal graft-versus-host disease
  • mechanisms of MAIT cell function during homeostasis, acute graft-versus-host disease and infection
  • determinants of increased susceptibility to respiratory syncytial virus infection after allogeneic stem cell transplantation

Targeting the gut and the microbiome to improve blood cancer treatments

Multiple projects available to suit Honours or PhD students Stem cell transplantation (SCT) remains the preferred treatment option for the majority of blood cancers providing alloimmunity to eradicate the disease and prevent relapse. However, graft-versus-host disease (GVHD) is a major complication that limits its effectiveness and utility, thus represents a clinical unmet need. Chemotherapy/radiation prior […]

Understanding infectious respiratory complications after stem cell transplantation

Multiple projects available to suit Honours or PhD students. Stem cell transplantation (SCT) remains the preferred treatment option for the majority of blood cancers providing alloimmunity to eradicate the disease and prevent relapse. However, this results in patients becoming critically immunocompromised after transplant such that infection with common respiratory viruses can be life threatening. Respiratory […]
