title: Glucocorticoid receptors in subpopulations of human lymphocytes defined by monoclonal antibodies.
abstract: Glucocorticoid receptors (GR) were investigated in subpopulations of lymphocytes identified by monoclonal antibodies. Purified T (OKT3+) and non-T lymphocyte subpopulations were isolated from human peripheral blood using Degalan bead columns coated with rabbit anti-human IgG. Purified subpopulations of OKT4+ and OKT8+ lymphocytes were obtained by coating the nonadherent population (T cells) from the first column with OKT4+ or OKT8+ and pouring it into a second Degalan column, coated with goat anti-mouse IgG. GR content and affinity were analyzed by a whole cell assay with [3H]dexamethasone as tracer. The numbers of GR in lymphocyte subpopulations (OKT3+ cells, non-T cells, OKT4+, and OKT8+ cells) were nearly equal. It is concluded that the differential effects of glucocorticoids on the circulatory kinetics of OKT4+ and OKT8+ cells probably are not related to differences in glucocorticoid receptors of these T-cell subpopulations.
