Examination of the neonatal immune response. We explore how adult derived stem cells can be transplanted even when mismatched (allogeneic transplantation).

Research Project Area: 

The Mucosal Immunology Laboratory, NUI Maynooth examines the neonatal immune response. This has grown out of our interests in childhood immunisation. We have examined immunity in a number of diseases important during pregnancy (B19 virus) or early life ( B. pertussis ). This work has shown how immunity in early life can be different to that in adults and how pathogens can alter immune responses. Together with REMEDI from NUI Galway, we are exploring how adult derived stem cells can be transplanted even when mismatched (allogeneic transplantation). We believe that adult stem cells maintain many aspects of the fetal graft, which allows these cells to be successfully used in regenerative medicine. If we are correct it may mean that adult derived stem cells can be used in a wide variety of new therapies.
