Within the immune system, there is a subgroup of immune cells, called T-regulatory cells. The function of these cells is to control and regulate other immune cells and prevent destruction of transplanted organs. One very promising solution to the problem of rejection is to generate tolerance. This can be done by increasing the number of this special T regulatory immune cells in transplant recipients’ bodies. In our BC Venture Grant, we proposed to find a novel and effective way to protect transplanted organ without putting the patients’ health in danger by avoiding the use immune suppressing medications.
