Abstract
Cell therapy and regenerative medicine have made remarkable progress in treating neurodegenerative disorders. Induced pluripotent stem cells (iPSCs) offer a promising source for cell replacement therapies, but their practical application faces challenges due to poor survival and integration after transplantation. Park et al. propose a novel therapeutic strategy involving the co-transplantation of regulatory T cells (Tregs) and iPSC-derived dopamine neurons. This combined approach enhances the survival of transplanted cells and protects against neuroinflammation-induced damage. In PD animal models, the co-transplantation approach significantly suppressed the host immune response, resulting in improved behavioral recovery. Additionally, Tregs demonstrate acute neuroprotection and contribute to delayed neuro-restoration in ischemic stroke. This combined approach of cell therapy with immunomodulation offers a promising avenue for advancing our understanding of neurological diseases and promoting the development of novel treatments.
