Description:
Interleukin-1 (IL-1) is a major regulator of inflammation and immunity. IL-1 induces T lymphocyte growth by acting as a second signal (together with antigen) in enhancing the production of interleukin-2 (IL-2). An IL-1-responsive element in the promoter region of the human IL-2 gene was similar to the binding site for the transcription factor AP-1. IL-1 enhanced expression of c-jun messenger RNA, whereas the antigenic signal enhanced messenger RNA expression of c-fos. Thus, the two components of the AP-1 factor are independently regulated and the AP-1 factor may serve as a nuclear mediator for the many actions of IL-1 on cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Muegge, K -- Williams, T M -- Kant, J -- Karin, M -- Chiu, R -- Schmidt, A -- Siebenlist, U -- Young, H A -- Durum, S K -- 5-T32-CA-09140/CA/NCI NIH HHS/ -- AI-R01-23879/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1989 Oct 13;246(4927):249-51.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Immunoregulation, Program Resources Inc., Frederick, MD 21701.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2799385" target="_blank"〉PubMed〈/a〉
