fVIII-Specific T-cell proliferative response is suppressed after blocking CD40-CD40L interaction in vivo.
T cells and peritoneal macrophages from 2 mice injected with fVIII (■) or 2 mice treated with anti-CD40L plus fVIII (●) were harvested at the end of the treatment and cocultured with increasing concentrations of fVIII. After 4 days, cells were pulsed with 1 μCi [3H]-thymidine, and incorporation of radioactivity was measured. Results are expressed as the mean of counts per minute (CPM) ± 1 SD of triplicate wells.
