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

STUDENT PROJECTS

In situ immune cell profiling using spatial transcriptomics in gastrointestinal graft-versus-host disease

Aspects of this project would be suitable for Honours, Masters, MPhil, MD and PhD students. Email the supervisor to discuss suitability. Background Acute gastrointestinal graft-versus-host disease (GVHD) is a common, life-threatening complication following allogeneic haematopoietic stem cell transplantation. Gut GVHD occurs when donor-derived T-cells traffic to host GI tract tissue in response to cytokine release […]

Identifying novel MAIT cell expansion strategies to mitigate graft-versus-host disease

Aspects of this project would be suitable for Honours, Masters, MPhil, MD and PhD students. Email the supervisor to discuss suitability. Background  Mucosal-associated invariant T cells (MAIT cells) are an important regulatory subset which possess potent anti-microbial functions, primarily due to their rapid, diverse and expansive cytokine production. Initially, MAIT cells were shown to respond […]

Harnessing the gut microbiome to improve stem cell transplantation

Aspects of this project would be suitable for Honours, Masters, MPhil, MD and PhD students. Email the supervisor to discuss suitability. Background Haematopoietic stem cell transplantation (HSCT) is considered the gold standard procedure for the treatment of high-risk blood cancers. However, graft-versus-host disease (GVHD) remains a barrier to the success of this life-saving immunotherapy. GVHD […]

Understanding infectious respiratory complications after stem cell transplantation

Aspects of this project would be suitable for Honours, Masters, MPhil, MD and PhD students. Email the supervisor to discuss suitability. Background Respiratory viral infections are a major global public health problem. RSV-induced bronchiolitis and pneumonia are the leading cause of hospitalization in infants and young children worldwide, while in adult allogeneic hematopoietic stem cell […]
