Median values (%) of the markers expressed by CD28-negative T cells and their counterparts CD28-positive cells
| Markers | CD4+CD28+ | CD4+CD28− | CD8+CD28+ | CD8+CD28− |
|---|---|---|---|---|
| HLA-DR | 10 (7–14) | 17 (13–24) | 46 (40–54) | 58 (25–74) |
| IFN-γ | 0·2 (0·1–3) | 1·2 (0–32) | 1·8 (1–3) | 2·1 (1–3) |
| Perforin | 1·2 (0·1–4) | 18 (1–36) | 1·5 (1–5) | 2·8 (1–12) |
| CD11b | 4 (3–8) | 27 (4–51) | 6 (4–9) | 25 (20–70) |
| IL-2 | 0·1 (0–0·2) | 0·3 (0–1·5) | 0·7 (0·4–1) | 2·6 (1–3) |
| CD7 | 87 (82–88) | 77 (72–89) | 91 (90–92) | 86 (84–91) |
The table shows the median values (range) in percentage of different markers expressed by negative or positive CD28 T cells from five infected patients. HLA-DR: human leucocyte antigen D-related; IL: interleukin; IFN: interferon.
