To this end, we performed paired single-cell RNA sequencing (scRNAseq) and surface protein sequencing (CITEseq) analysis, comparing P14 cells from d8 acute LCMV Armstrong infection (4,499 cells) and chronic LCMV Docile infection (4,967 cells) with d0–1 IFNAR-blocked LCMV Armstrong at both d8 (5,061 cells) and d14 (3,102 cells). Here, IFNAR1 is linked to infection.
