Interleukin-2 (IL-2) and its receptor
Medical Oncology and Tumor Pharmacotherapy, 1986The interleukin-2 (IL-2) receptor system which is responsible for T-cell cycle progression is a unique hormone-receptor system in that both the ligand and the receptor need to be induced. In the present article I will review the biological and molecular characteristics of IL-2 and its receptor, as well as the differential triggering and growth ...

Abstract The biologic actions of IL-2 are mediated by the IL-2R, a multisubunit receptor complex displayed on the surface of lymphocytes and select other hematopoietic lineages. The IL-2R exhibits multiple affinities for IL-2 that result from the monomeric (alpha), heterodimeric (alpha beta and beta gamma), and heterotrimeric (alpha beta

AbstractMouse fibroblasts do not ordinarily express components for the interleukin‐2 receptor (IL‐2Rα, β, and γ). An analysis of these cells by reverse transcription followed by polymerase chain reaction, however, indicates the presence of transcripts specific for the IL‐2R β and γ genes. Transfection of the cDNA for the α chain of the human IL‐2R into

Differential Effects of IL-2 and IL-15 on Expression of IL-2 Receptor α
Biochemical and Biophysical Research Communications, 2001IL-2 and IL-15 have overlapping functions since they share the IL-2Rbetagamma receptor complex. However, each cytokine has a private alpha receptor namely IL-2Ralpha for IL-2 and IL-15Ralpha for IL-15. As a consequence the effects of the two cytokines may differ.

Transcription and translation dependent induction of interleukin 2 (IL-2) and IL-2 receptors
Immunology Letters, 1984Our previous findings on the expression of Interleukin 2 (IL-2) receptors have shown that under the influence of certain drugs, it was possible to dissociate IL-2 production from the appearance of IL-2 receptors on human peripheral blood lymphocytes (PBL).

IL 2 receptor induction on human T lymphocytes: role for IL 2 and monocytes.
The Journal of Immunology, 1985Abstract In this report we studied the requirements for the activation and proliferation of highly purified human T lymphocytes. Purified T cells incubated for 3 days with PHA neither proliferate nor express IL 2 receptors as detected by FACS analysis with the use of anti-Tac antibodies.

IL-2-PE40 is cytotoxic for activated T lymphocytes expressing IL-2 receptors.
The Journal of Immunology, 1988Abstract IL-2-PE40 is a chimeric molecule in which IL-2 is attached to the amino end of modified Pseudomonas exotoxin molecule lacking cell recognition domain. This molecule was extremely toxic for Con A-stimulated spleen cells from mice. Moreover, IL-2-PE40 has suppressive effect against Ag-activated cells; it inhibits the generation of

Abstract The accessory cell requirements for the induction of the IL 2 receptor by the lectin Con A on murine T cell subsets were directly assayed with anti-IL 2 receptor monoclonal antibodies. Substantial levels of IL 2 receptor expression were induced on T lymphocytes of the MHC class I-restricted, suppressor/cytotoxic phenotype (L3T4-,

Cloning of the γ Chain of the Human IL-2 Receptor
Science, 1992A third subunit, the γ chain, of the human interleukin-2 receptor (IL-2R) was identified, and a complementary DNA clone encoding this member of the cytokine receptor family was isolated. The γ chain is necessary for the formation of the high- and intermediate-affinity receptors, which consist of αβγ heterotrimers and βγ heterodimers, respectively.
