FIG 8.

Changes in Ki-67 expression on total B cells over the course of progressive SIVsab infection of AGMs and nonprogressive SIVsab infection of PTMs. (A to C) Fold increase of Ki-67 expression in PBMCs (A), lymph nodes (B), and intestine (C). Dotted lines mark the baseline levels of the different cell subsets. The Mann-Whitney U test was used to assess significance. Error bars correspond to standard errors of the means. Significant changes from the preinfection baseline levels are indicated as follows: *, P < 0.05; **, P < 0.01; and ***, P < 0.001. (D) MFI of TLR-2 expression on total B cells over the course of progressive SIVsab infection of AGMs and nonprogressive SIVsab infection of PTMs. AGMs are shown by green circles and PTMs by red squares. Results for uninfected (green circles) versus SIVsab-infected AGMs (green diamonds) and uninfected (red squares) versus SIVsab-infected PTMs (red triangles) are shown. Values of individual animals are plotted, with the group means (long solid lines) and standard errors of means (short solid lines) shown. The Mann-Whitney U test was used to assess significance; P values are shown.
