Abstract:
OBJECTIVE:To establish a mouse model of respiratory syncytial virus (RSV) infection after hematopoietic stem cell transplantation, so as to lay the foundation for future research on RSV infection and related complications after hematopoietic stem cell transplantation.
METHODS:Bone marrow cells and spleen cells were transplanted to C57BL/6 mice after myeloablative treatment to establish a mouse model of allogeneic hematopoietic stem cell transplantation. The chimerism rate was detected by flow cytometry 3 and 7 weeks after transplantation. The transplanted mice were infected with RSV by nasal drops. The lung tissues were collected 5 days after infection for identification of infection, and lung tissues were analyzed for pathology 2 weeks and 2 months after infection.
RESULTS:The chimerism rate was > 90% at 3 and 7 weeks after transplantation. Successful infection was detected 5 days after RSV infection, and there were severe and persistent pathological changes in the lung tissues of the mice 2 weeks and 2 months after infection.
CONCLUSION:RSV infection in stable chimeric mice after hematopoietic stem cell transplantation can cause significantly persistent lung disease, which lays foundation for the prevention and treatment of RSV infection and the mechanism of later bronchiolitis obliterans after hematopoietic stem cell transplantation.
