Internalization of interleukin 2 is mediated by the beta chain of the high-affinity interleukin 2 receptor
High-affinity IL-2-R correspond to a membrane receptor complex composed of two different IL-2-binding proteins, the Tac antigen (alpha chain) and a 70-75 kD beta chain. Using cell lines that express either the alpha or the beta protein, we demonstrate that IL-2 internalization occurs when ligand is bound to the isolated beta chain, but not when it is bound to the isolated alpha chain. The kinet...
متن کاملA humanized antibody that binds to the interleukin 2 receptor.
The anti-Tac monoclonal antibody is known to bind to the p55 chain of the human interleukin 2 receptor and to inhibit proliferation of T cells by blocking interleukin 2 binding. However, use of anti-Tac as an immunosuppressant drug would be impaired by the human immune response against this murine antibody. We have therefore constructed a "humanized" antibody by combining the complementarity-de...
متن کاملThe interleukin-2 receptor.
The human body defends itself against foreign invaders such as bacteria and viruses by a defense system that involves antibodies and thymus-derived lymphocytes (T cells). A major advance over the past decade has been the demonstration that the diverse cells within the immunological network communicate with each other not only by cell/cell contact but also by an array of hormone-like proteins te...
متن کاملExpression of interleukin-2 receptor beta subunit in hematopoietic malignancies.
The expression of the interleukin-2 (IL-2) receptor was studied in neoplastic cells derived from acute leukemias, T-cell lymphoblastic lymphomas, peripheral T-cell lymphomas, chronic lymphocytic leukemias, well-differentiated lymphocytic lymphomas, and established cell lines by both flow cytometric analysis and sodium dodecyl sulfate/polyacrylamide gel electrophoresis (SDS-PAGE) after affinity ...
متن کاملInterleukin-3-induced downregulation of the expression of interleukin-2 receptor beta chain in human T cells.
We examined the effect of interleukin-3 (IL-3) on human CD4+ cloned T cells, P607 and 1C2. By flow cytometric analysis, we found that IL-3 downregulated the surface expression of IL-2 receptor (R) beta chain in a dose-dependent manner but had little effect on that of IL-2R alpha chain. A simultaneous 125I-labeled IL-2 binding assay showed a decrease in the number of high-affinity, but not of lo...
