CD8A and infection: The proportion of NCR1+/CD8+ NK cells was similar in JPPs and jejunum and did not change during the infection (Figure 5B), which was in agreement with the results shown in Figures 3C and D. However, the CD8tot/NCR1- cells that already predominated in JPPs and particularly in the jejunum at homeostasis increased significantly during infection (3–6 dpi); this increase was not due to a specific increase of the included CD8hi/NCR1- sub population (shown in Figure 5A).
