Design of the hcGAS mouse

The humanized cGAS model was developed by Knockin at the mouse cGAS locus and expresses a full human cGAS.

hcGAS features

  • cGAS is entirely humanized
  • Physiological regulation of the human cGAS
  • Fully functional mouse immune system
  • Lack of expression of the murine target gene, thus avoiding cross-reactivity
  • Human cGAS expression in brain and lung of cGAS humanized mice

    cGAS expression was assessed in brain and lung of 9-week-old WT and hcGAS mice by Western Blot.

     
  • Human cGAS antagonist prevents BCV-induced cytokine release in hcGAS, but not in WT mice

    hcGAS and WT mice were treated with anti-cGAS antibody or vehicule and, after 24h, were injected with different dosage of BCV. 6h later, plasma was harvested from the mice and cytokine levels (IFN-α, IP-10, IFN-β) were evaluated.
