When examining gE:gI expression in non-MAIT cell (ie MR1 Tet-) CD4+ cells (mean 15.8%, range 4.8-22%) and non-MAIT cell (ie MR1-Tet-) CD8+ cells (mean 16%, range 5.7-24.1%) populations, we observed no significant difference in infection level when compared to MAIT cells across 14 different donors (Figure 1B). Here, MR1 is linked to infection.
