Figure 4

Preservation of central memory (CM; CD28+CD95+) CD4+ T lymphocytes (a) and CCR5+ central memory CD4+ T lymphocytes (b) was assessed on days 0, 14, 28, 56 and 112 after challenge. Ki67 staining of central memory CD4+ (c), CCR5+ central memory CD4+ (d), effector memory (EM; CD28-CD95+) CD4+ (e), and CCR5+ effector memory CD4+ (f) T lymphocytes was also determined. Mean responses with standard errors are shown (af). g, Preservation of gastrointestinal CD4+ T lymphocytes was assessed in duodenal biopsies on day 21 after challenge. Comparisons were performed by two-sided Wilcoxon’s rank-sum tests.
