Interleukin-2 (IL-2) is a lymphokine synthesized by some T-cells following activation. Resting T-cells do not express IL-2 receptors but receptors are rapidly expressed on T-cells following the interaction of antigens, mitogens, or monoclonal antibodies with the antigen specific T-cell receptor complex.

Interleukin-2 receptors in infectious mononucleosis
Immunology Letters, 1989The majority of peripheral blood mononuclear cells (PBMC) from acute-phase infectious mononucleosis (IM) patients express high levels of T10 (CD38) and HLA-DR surface antigens, which are markers characteristic of activated T cells. However, Tac antigen (p55) expression on these cells was not detectable by flow cytometric immunofluorescence, and only a ...

Interleukin-2, Interleukin-15, and Their Receptors
International Reviews of Immunology, 1998Both IL-15 and IL-2 are 14-15 kDa members of the four alpha-helical bundle family of cytokines that have T cell growth factor activity. In contrast to the pattern manifested by IL-2, IL-15 mRNA is produced by a wide variety of tissues other than T cells. We have demonstrated that IL-15 expression is posttranscriptionally regulated by multiple elements,

The Journal of Immunology, 1985
Abstract The role of interleukin 2 (IL 2) on the expression of IL 2 receptors and on the synthesis of gamma-interferon (gamma-IFN) by human thymocytes was investigated. Human thymocytes isolated from specimens obtained during cardiac surgery of infants and children were induced with one or all of the following agents: IL 2, concanavalin ...

Serum Interleukin-2 and Soluble Interleukin-2 Receptor in Gestrational Trophoblastic Diseases [PDF]
Journal of the Society for Gynecologic Investigation, 1996 To investigate serum interleukin-2 (IL-2) and soluble interleukin-2 receptor (SIL-2) levels in gestational trophoblastic diseases (GTD).Sixty-six patients with GTDs and 23 first-trimester healthy pregnant women (controls) participated in this study.

Interleukin 2/interleukin 2 receptor system in type 1 diabetes
Diabetes Research and Clinical Practice, 1989There is increasing evidence that cellular immune abnormalities are involved in the pathogenesis of type 1 diabetes mellitus. The non-obese diabetic (NOD) mouse, a model of human type 1 diabetes, develops mononuclear cell infiltration of its pancreatic islets (insulitis), leading to /3 cell destruction and overt diabetes [l]. In recent studies, most of

Interleukin-2, anti-interleukin-2 receptor antibody, and activation of macrophages
Cellular Immunology, 1990Macrophages treated with IFN-gamma and IL-2 before exposure to parasites develop the ability to resist infection with amastigotes of Leishmania major. In this cooperative interaction of cytokines, IL-2 can be replaced with any of several mAb directed against the beta chain of the IL-2 receptor, but not by antibodies to a number of other cell receptors ...

Interleukin-2 receptor expression and interleukin-2 production in bullous pemphigoid
Archives of Dermatological Research, 1990Expression of interleukin-2 (IL2) receptors was studied on peripheral blood lymphocytes (PBLs) in 25 patients with bullous pemphigoid. Analysis was carried out by flow cytometry. Without immunosuppressive therapy expression of IL2 receptors only on T cells (CD5) was significantly increased as shown by double staining (11.9% +/- 7.8% vs 2.1% +/- 1% in ...

Biotinylated recombinant interleukin-2
Journal of Immunological Methods, 1988Recombinant interleukin-2 was biotinylated using a N-hydroxyl-succinimidyl [3H]biotin ester. The biotinylated lymphokine retained full binding and growth-promoting activities when assayed on the interleukin-2-dependent murine cell line HT-2. In preliminary studies, biotinylated interleukin-2 was used in conjunction with immunogold staining to ...

The released interleukin 2 receptor binds interleukin 2 efficiently.
The Journal of Immunology, 1986Abstract The released interleukin 2 receptor (IL 2R) molecule was characterized in order to clarify its biochemical structure and to determine its functional capacity. Enzymatic digestions demonstrated that the released IL 2R, like the cell surface IL 2R, is a complex glycoprotein, modified by the addition of both N- and O-linked ...
