    • Surface staining of lymphocytes was performed using anti-monkey CD3-biotin (BioSource International), anti-human CD4-APC (Exalpha), anti-human CD45RA-RD-1 (Coulter), anti-human CD16-PE (Coulter), and anti-CD20 (Becton Dickinson). Antihuman CD8-APC (Caltag) was used on occasion. Additional antibodies that are normally used to characterize human lymphocyte subpopulations were not used because of their poor reactivity with rhesus lymphocytes.

    • After surface staining, cells were treated with FACS Lysing Solution (Becton Dickinson) for 15 min at room temperature, followed by overnight fixation in 1% paraformaldehyde and 0.05% NP-40 in phosphate-buffered saline (PBS) at 4°C. Cellular DNA was then denatured with 50 Kunitz units of DNase-I (Boehringer Mannheim) for 30 min at 37°C, before staining with anti-BrdU (Becton Dickinson) in 5% fetal bovine serum and 0.5% NP-40 in PBS for 45 min. Cells were washed twice before flow cytometric analysis.

    • This model assumes that the average rates of cell proliferation and death are constant, as are the source rates, during labeling and delabeling. Although the source may represent cells being exported from the thymus or extrathymic tissues, which are expected to label rapidly with BrdU, it could also include a population of resting or slowly dividing T cells, which upon activation would undergo rapid clonal expansion and enter the subpopulation of cells acquiring label during the experiment. Indeed, we have developed a model based on such a mechanism, which provides the source while explaining the observed findings (S. Bonhoeffer and A. Perelson, unpublished results).

    • note
    • After a sufficient number of cell divisions following the removal of BrdU, some cells may have so little label in them that they are not distinguishable from unlabeled cells. We ignored this possible means of loss of labeled cells, because a close examination of our BrdU-intensity data did not reveal any substantially lower values with the passage of time.

    • -1. Our estimate of p, which is for the total CD4 population, lies between their estimates for the primed and unprimed populations. However, our estimate of d is substantially larger, perhaps because of the fact that McLean and Michie analyzed cross-sectional data obtained from patients rebuilding their lymphocyte pool after radiotherapy, who may indeed have had very low T cell death rates. Our data reflect a pool of cells that acquired label during the experiment. This may be a subset of lymphocytes that turn over more rapidly than the total population.
