IRF8 +32 KO mice

— 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…

Irf8 Delta32 Mice

— Irf8 Delta32 mice have a CRISPR targetted deletion in the enhancer of the mouse Irf8 gene located at +32 kilobases from the Irf8 gene promoter. This deletion removes the binding site for the Jun/Batf3/Irf8 complex and results in a complete and permanent elimination of the development of the cDC1 lin…

Xcr1 IRES mCherry-hCre Mouse Strain

— Xcr1 IRES mCherry-hCre Mouse Strain

This genetically modified mouse strain expresses the fluorescent marker mCherry and a human codon optimzed Cre in the same transcript as the chemokine receptor XCR1. XCR1 is specifically expressed in cDC1s, allowing specific deletion of genes in and the fluoresce…
