IFNAR1 and infection: After anti-IFNAR1 treatment, the Venus protein signal increased in several myeloid cells in the DLN (Fig. 6D; Fig. S5A), including both DC1s (CD11c+ MHC-II+ Xcr1+) and DC2s (CD11c+ MHC-II+ Sirpα+), although we cannot definitively distinguish direct infection from phagocytosis of infected cells using this assay.
