Interleukin 2 (IL-2) augments transcription of the IL-2 receptor gene.
We demonstrate that purified interleukin 2 (IL-2) can directly upregulate IL-2 receptor expression on phytohemagglutinin-activated T lymphocytes maintained in culture until IL-2 receptor expression had markedly declined. The IL-2-induced increase in IL-2 receptor number is maximal within 12 hr, requires new RNA and protein synthesis, and is mediated by an interaction of ligand with the high-aff...
متن کاملNegative regulation of interleukin 2 transcription by the glucocorticoid receptor
Glucocorticoid-dependent transcriptional enhancement is known to occur through the interaction of the glucocorticoid receptor (GR) with specific DNA response elements. In contrast, negative regulation of gene expression by this class of hormone is less well understood. Glucocorticoids are potent immunosuppressive agents acting primarily by inhibiting T lymphocyte activation and lymphokine produ...
متن کاملThree distinct IL-2 signaling pathways mediated by bcl-2, c-myc, and lck cooperate in hematopoietic cell proliferation
Two interleukin-2 receptor-dependent signaling pathways have thus far been identified: the c-fos/c-jun induction pathway mediated by src family protein-tyrosine kinases and the c-myc induction pathway. Here, we provide evidence for the existence of a third, rapamycin-sensitive pathway, which results in the induction of another proto-oncogene, bcl-2. In the hematopoietic cell line BAF-B03, the e...
متن کاملInterleukin-2 (IL-2) expression in livers of patients with chronic hepatitis C virus (HCV) infection.
The studies performed till now have pointed to an increased serum levels of interleukin 2 (IL-2) in infection with hepatitis C virus (HCV). The present study was aimed at examining intrahepatic expression of IL-2 in children (n=15) and in adults (n=11) with chronic hepatitis C as well as its correlations with histological lesions and selected clinical data. The immunocytochemical techniques and...
متن کاملRegulation of SCN3B/scn3b by Interleukin 2 (IL-2): IL-2 modulates SCN3B/scn3b transcript expression and increases sodium current in myocardial cells
BACKGROUND In the initiation and maintenance of arrhythmia, inflammatory processes play an important role. IL-2 is a pro-inflammatory factor which is associated with the morbidity of arrhythmias, however, how IL-2 affects the cardiac electrophysiology is still unknown. METHODS In the present study, we observed the effect of IL-2 by qRT-PCR on the transcription of ion channel genes including S...
