Brief Summary
Safety and Effectiveness of Donor γδT Cell Infusion to Prevent Relapsed/Refractory Leukemia Rescue Relapse After Allogeneic Hematopoietic Stem Cell Transplantation
Detailed Description
γδT cells belong to the innate immune system and have a powerful anti-tumor effect. Leukemia patients transplanted with allogeneic hematopoietic stem cells have an important role in controlling leukem...
