When examining the co-receptor subpopulations, there was a significantly higher level of infection of CD4+ (mean 23.6%, range 12-32.5%) and double positive (CD4+/CD8+) (mean 22.8%, range 9.6-35.1%) MAIT cells compared to CD8+ (average 16.8%, range 6.2-22.7%) and double negative (CD4-/CD8-) (mean 16%, range 5.4- 31.4%) MAIT cells (Figure 2B). Here, CD8A is linked to infection.
