Abstract：
:The generation and cell surface expression of IL-2 receptors was monitored by: (i) an ELISA that permits quantitative determination of detergent-solubilized or soluble IL-2 receptors; and (ii) detection of the binding of 125I-labelled recombinant IL-2 and of anti-IL-2 receptor antibodies to receptor bearing cells. Upon lectin stimulation both high and low affinity IL-2 receptors became expressed in parallel at the cell surface. Both high and low affinity receptors were upregulated by IL-2. Upon lectin activation the amount of cell-associated receptors increased and on day 2 of the culture period IL-2 receptors were detectable in the culture supernatant. IL-2 upregulated both high and low affinity IL-2R expression on T-lymphoblasts. IL-2R bearing leukemic cells and T lymphoblasts released IL-2R when cultured in vitro. IL-2R release by T lymphoblasts was enhanced dramatically by IL-2. On the other hand, IL-2-receptor positive leukemic cells released receptors in an IL-2 independent manner. Release of receptors could also be detected in serum-free medium. At least a part of the released receptors could be specifically bound to immobilized pure recombinant IL-2 and to monoclonal anti-IL-2-receptor antibodies. Small but significant amounts of soluble IL-2 receptors were detectable in the sera of normal mice. In sera of mice inoculated with IL-2-receptor positive syngeneic leukemic cells, elevated levels of IL-2 receptors were detectable. Release of IL-2 receptors seems to represent one of the major routes by which the receptors are cleared from the cell surface.
