Enhancing Tolerance of Immune System towards Transplants

Scientists at NCCS are exploring mechanisms for enhancing immune tolerance for the purpose of increasing acceptance of transplants by the body. In particular, they are studying the role of gamma-delta (γδ) T cells in increasing immune tolerance. It has been identified that the population of γδ T cells in the body increases with age and interestingly this is also one of the correlates with lower rate of success of transplant in aged population. Further studies are ongoing to verify these findings. Potential use of this research would be in developing therapeutics to increases chances of success in transplant cases.
