IRF8 +32 KO mice

Tech ID: T-018830

Researchers first identified and then used CRISPR to delete an enhancer located at +32 kb of the Irf8 transcriptional start site in mice. Knocking out this enhancer revealed that interferon regulatory factor 8 (IRF8) is required for the development of classical type 1 dendritic cells (cDC1s) but not for pre-cDC1 specification, which instead is driven by a +41-kb Irf8 enhancer. These Irf8 +32−/− mice can therefore be useful in better understanding the development of cDC1s, which are essential for antiviral and antitumor immunity.

These mice have been deposited in Jackson Labs (Stock No: 032744).
