Figure 5.

Apoptosis progresses more rapidly in LP than in GC. (A-F) Duodenal sections from one representative macaque at 14 dpi and 28 dpi were stained with anti-cleaved caspase-3 Ab (A-F). Inserts from left panels are shown in middle (B and E; showing GC) and right panels (C and F; showing follicular T-cell zones). Original magnification x100 in left panels and x400 in middle and right panels. (G-H) Each symbol corresponds to the mean density of cleaved caspase3+ cells per μm² of follicular T-cell Zone (G) and to the mean number of cleaved caspase-3⁺ cells per GC (H) per macaque. Bars represent median values for each group. *p value < 0.05 (Mann–Whitney).
