Model Description

Background: C57BL/6J



  • No physiological deregulation: Unaltered immune cell distribution, and T helper cell activity
  • Lack of expression of the corresponding murine gene



The human CD4 mouse model allows in vivo efficacy and safety assessment of compounds targeting human CD4, and is generally used in fields of inflammation, autoimmune diseases, immuno-oncology and HIV infection.


  • CD4 expression analysis
Model Validation

Figure 1. Human CD4 replaces murine CD4. Homozygous CD4 humanized mice display human-CD4 expression in PBMC. No murine CD4 expression is observed. Blood samples from wild-type and homozygous CD4 humanized mice stained with a combination of mAbs (anti-murine CD4, anti-human CD4) and analyzed by flow cytometry.


  • Immune cells distribution analysis
Model Validation

Figure 2. Unaltered immune cell distribution. Homozygous CD4 humanized mice display same frequencies of B cells, NK cells and T cells in spleen as the wildtype mice. Splenocytes are stained with different mAb combinations to assess frequencies of lymphocyte subsets measured by flow cytometry. Grey bars represent values for wild-type mice and hatched bars represent values for CD4 humanized mice.


  • Cytokines expression analysis
Model Validation

Figure 3. Conserved cytokine expression profile. Homozygous CD4 humanized mice display similar cytokine expression after ConA stimulation. IL-2, IFN-γ and IL-4 concentrations in culture supernatants of mouse splenocytes stimulated with Con A are measured by using a 3-Plex Luminex kit. Black bars represent values for wild-type mice and hatched bars represent data for humanized CD4 mice.


  • Ig production analysis
Model Validation

Figure 4. Similar Ig production. Homozygous CD4 humanized mice display similar anti-KLH isotyping to wild-type mice. Anti-KLH specific IgG1, and IgG2b polyclonal antibodies are assessed by sandwich ELISA in the serum of mice at day 28 after immunization with KLH and CFA. Serum samples from wild-type (WT) or homozygous CD4 humanized mice (HO CD4) were tested at different dilutions plotted against OD values.
