The 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 کاملThe human interleukin-2 receptor.
Complementary DNAs corresponding to the human receptor for interleukin-2 (IL-2) have been molecularly cloned, sequenced, and expressed in both COS-1 and L cells. The human genome appears to contain a single structural gene for this receptor located on the short arm of chromosome 10 (band 14-15). However, when transcribed, at least two families of mRNAs are produced, which vary in length due to ...
متن کاملInterleukin 2 receptor-targeted cytotoxicity. Interleukin 2 receptor- mediated action of a diphtheria toxin-related interleukin 2 fusion protein
The IL-2 toxin-mediated inhibition of protein synthesis in high affinity IL-2-R-positive murine and human T cell lines has been examined. Both excess free IL-2 and mAb to the Tac epitope of the p55 subunit of IL-2-R are shown to block the action of IL-2 toxin; whereas, agents that interact with other receptors or antigens on the T cell surface have no effect. We show that IL-2 toxin, like dipht...
متن کاملEssential role of the interleukin 2-interleukin 2 receptor pathway in thymocyte maturation in vivo
The role of the IL-2-IL-2-R pathway in thymocyte differentiation in vivo is unknown. We have examined fetal thymocyte development in vivo, under conditions where all IL-2-R were saturated from day 13 of gestation with anti-IL-2-R mAbs that were previously shown to render mature T cells unable to respond to IL-2. This produced a dramatic change in the composition of developing T cells: thymocyte...
متن کاملTransmembrane signaling of interleukin 2 receptor. Conformation and function of human interleukin 2 receptor (p55)/insulin receptor chimeric molecules
Chimeric genes were constructed which gave rise to the expression of novel receptor molecules consisting of the extracellular domain of the human interleukin 2 receptor (IL-2-R; p55 or Tac antigen) joined to the transmembrane domain and either full-length or truncated cytoplasmic domain of the human insulin receptor (Ins-R). Expression studies using mouse T cell line EL-4 revealed that the chim...
