Human Immune System Mice

HUMAN iMMUNE SYSTEM MICE

huPBMC-NCG-MHC-dKO

Type : PBMC Humanized Mice
Strain Number : T060123
Background Strain: NCG-MHC-dKO [T050886]

STRAIN DESCRIPTION

The huPBMC-NCG mouse model is established by transplanting Peripheral Blood Mononuclear Cells (PBMCs) from healthy donors into highly immunodeficient NCG mice with double knockout of murine MHC class I and II genes [NCG-MHC-dKO T050886] to create a human immune system-reconstituted model. The additional deletion of MHC I/II minimizes xenogeneic immune interactions, thereby reducing the severity of graft-versus-host disease (GvHD). Similar as conventional HuPBMC-NCG [T057056], this model enables rapid reconstitution of human T cells and is particularly suited for short-term studies involving T-cell-mediated immune responses, immuno-oncology research, and GvHD drug evaluation. The MHC-dKO background also improves experimental consistency and prolongs the survival window compared to conventional huPBMC-NCG model.
