FIG. 4.

Jejunal IEL counts in mice that received lymphocytes from previously infected donors or from sham-inoculated CDs. Lymphocytes used were whole SMLN lymphocyte preparation, enriched CD4⁺ T cells, or enriched CD8⁺ T cells, and counts were performed 3 days after transfer. Values are expressed as number of IEL per 100 enterocytes (% IEL) (mean ± SEM [error bars]). (* P < 0.05 versus paired CD group; n = 5 to 10 mice per group).
