Figure 4

Alterations in mucosal lymphocyte populations eight weeks post-infection. Box and whisker plots show the median with upper and lower quartile represented by the boxes, and minimum and maximum values shown by the whiskers. Percent of CD4+ T cells in LPL (A), CD8α+ T cells in IEL (B), and CD8β+ T cells in IEL (C) are shown for control, high, middle and low dose groups at euthanasia. Statistical significance was calculated using ANOVA, with p-value shown for FIV-infected groups compared to controls.
