| Wk postinfection | % ofa:
|
|
|---|---|---|
| CD4+ CD44high T cells | CD8+ CD44high T cells | |
| 0 | 56.4 ± 5.9 | 37.4 ± 1.3 |
| 1 | 57.7 ± 6.3 | 42.8 ± 9.5 |
| 2 | 92.4 ± 1.5 | 84.7 ± 3.6 |
| 3 | 93.4 ± 0.9 | 92.3 ± 1.1 |
| 4 | 92.2 ± 0.7 | 91.5 ± 0.5 |
Cells were gated on CD4+ or CD8+, and expression of CD44 within each gate was analyzed.
