Successful cell replacement strategies for brain repair depend on graft integration into the neural network, which is affected by the immune response to the grafted cells. Using Parkinson disease as an example, in this chapter, we consider the immune system interaction and its role in autologous vs heterologous graft survival and integration, as well as past and emerging strategies to overcome the immunologic response. We also reflect on the role of nonhuman primate research to assess novel approaches and consider the role of different stakeholders on advancing the most promising new approaches into the clinic.
