Cell Therapy in Transplantation

Lab head: Min Hu
Location: The Westmead Institute for Medical Research, Westmead Clinical School

The main research interest is the development of therapeutic strategies to improve the clinical outcomes of islet and kidney transplantation to achieve complete immunological tolerance to allografts. These include investigating the immune and genetics profile of islet and kidney transplant patients, generating allospecific Tregs, developing novel regimens for tolerance induction in humanised mouse models of islet transplantation, and developing clinical grade Tregs for clinical trials.

Induction Of Transplant Tolerance in Mouse Transplantation Models

Primary supervisor: Min Hu

IL-7 plays an important role on memory regulatory T cells (Tregs) for their maintenance in peripheral tissues. IL-7/anti-IL-7mAb complexes restore T cell development and induce homeostatic T cell expansion without lymphopenia in IL-7-deficient mice.  The study aims to investigate the role of IL-7 on supporting CD4+Foxp3+ Treg survival in the alloresponse and whether IL-7/anti-IL-7mAb complexes can induce Treg  expansion in a murine skin and islet transplant models.
