NSG™ Variants by Research Area

Innovative research models, built using the NOD scid gamma (NSG™) mouse

The versatility of NODscid gamma mice (005557) makes this strain the ideal platform to develop refined genetic models in multiple disease areas including immunology, cancer, transplantation and infectious disease. Innovative mouse strains, built on NSG™, with enhanced transgenic and targeted genetic modifications, allow sophisticated experimentation in multiple research areas.

Immunology

• NSG™ HLA Class I transgenic strains (009617 and 014570), expressing A2 haplotypes

• NSG™ expressing EGFP (021937)
  
  • Expresses EGFP in all cells of the embryo and adult.
  • Facilitates visualization of allogeneic and xenogeneic grafts
• NSG™ expressing human IL15 cytokine (030890) (030890)
  • Improved function and abundance of human NK cells following CD34 humanization (Brehm, et al. 2018)
• NSG™ without MHC class I or class II molecules (025216)
  • Most resistant to xeno-GVHD of all NSG variants (Brehm, et al. 2018)
• NSG™ with Kit mutation (026622)
  • Can be humanized with CD34 cells in the absence of preconditioning irradiation (McIntosh, et al. 2015)

HIV & other infectious diseases

• NSG™ HLA Class I transgenic strains (009617 and 014570), expressing A2 haplotypes
  
  • Allow HLA restriction of developing human CD8 cells in humanized models, and provide improved platforms for viral infection and vaccine models (Strowig, et al. 2009; Shultz, et al. 2010)
  • Antibody responses improved in a Dengue virus infection model (Jaiswal, et al. 2012)
• NSG™ HLA Class II transgenic strains, expressing DR1 (012479) and DR4 (017637) haplotypes
  
  • Allow HLA restriction of developing human CD4 cells and improve interactions with antigen-presenting cells;
  • Enhanced IgG responses
• NSG™ mice lacking MHC class I, NSG™ B2m (010636) and NSG™ (KbDb ) null (023848)
  
  • Enable longer studies following human PBMC engraftment (King, et al. 2008 and Covassin, et al. 2013)

Cancer

• NSG™ transgenic human IL-3, CSF2, Kit ligand (013062)
  
  • Show enhanced patient-derived acute myeloid leukemia engraftment (Wunderlich, et al. 2010)
• NSG™ Hprt mice (012480)
  
  • Facilitates isolation of human cancer cells from mouse stroma in vitro, and enable establishment of new patient-derived cell lines (Kamiyama, et al. 2013)
• NSG™ expressing EGFP (021937)
  
  • Expresses EGFP in all cells of the embryo and adult
  • Facilitates visualization of allogeneic and xenogeneic grafts

Transplantation research

• NSG™ without MHC class I or class II molecules (025216)
  • Most resistant to xeno-GVHD of all NSG variants (Brehm, et al. 2018) 
• NSG™ lacking MHC class I, NSG™ B2m (010636) and NSG™ (K^b ) null (023848)
  
  • Enable longer studies following human PBMC engraftment (King, et al. 2008 and Covassin, et al. 2013) 
• NSG™ lacking MHC class II (021885)
  
  • Resistant to xenogenic graft-versus-host-disease (Covassin, et al. 2011)
• NSG™ expressing EGFP (021937)
  
  • Expresses EGFP in all cells of the embryo and adult
