The 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 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 کاملInterleukin-2 and soluble interleukin-2 receptor in bronchoalveolar lavage fluid from patients with bronchial asthma.
To clarify the interrelation between interleukin-2 (IL-2) and soluble IL-2R receptor (sIL-2R), as products of T-cell activation in the bronchial tree of patients with bronchial asthma, we measured the concentration of IL-2, sIL-2R, and the cellular composition in bronchoalveolar lavage (BAL) fluid. We also measured physiologic parameters, including provocation concentration of histamine require...
متن کاملLocalization in human interleukin 2 of the binding site to the alpha chain (p55) of the interleukin 2 receptor.
Human interleukin 2 (IL-2) analogs with defined amino acid substitutions were used to identify specific residues that interact with the 55-kDa subunit (p55) or alpha chain of the human IL-2 receptor. Analog proteins containing specific substitutions for Lys-35, Arg-38, Phe-42, or Lys-43 were inactive in competitive binding assays for p55. All of these analogs retained substantial competitive bi...
متن کاملBacterial Overexpression of the Human Interleukin-2 in Insoluble Form via the pET Trx Fusion System
Selection of a system for successful recombinant protein production is important. The aim of this study wasto produce high levels of human interleukin-2 (hIL-2) in soluble form. To this end, the pET32a vector inEscherichia coli BL21 (DE3) was used as an expression system, since it was previously used for the productionof mouse IL-2 in soluble form. The results indicated that c...
