Acquired immunodeficiency syndrome (AIDS) results from infection with a human immunodeficiency virus (HIV). The long terminal repeat (LTR) region of HIV proviral DNA contains binding sites for nuclear factor kappa B (NF-kappa B), and Recent findings The present study was based on reports that antioxidants which elimi... | 5.15625 | bioscope | 1 |
Endothelial cells (EC) act as APC for resting PBL in vitro, and We previously reported that human umbilical vein EC provide costimulatory signals to PHA-stimulated PBL via CD2:lymphocyte function-associated Ag-3 and an unidentified ligand pair, resulting in a three- to eight-fold enhancement of IL-2 production. The ph... | 5.09375 | bioscope | 1 |
Platelet-activating factor is a potent mediator of the inflammatory response. Studies of the actions of platelet-activating factor have centered mainly around neutrophils, monocytes, and platelets. In this report we begin to uncover the influence of platelet-activating factor on B lymphocytes. Employing the EBV-transfo... | 4.90625 | bioscope | 1 |
The human immunodeficiency viruses (HIVs) Since expression of the viruses is in large part regulated by the sequence elements in their long terminal repeats (LTRs), this study was directed to an analysis of the regulatory elements in the HIV-2 LTR. The HIV-2 LTR was found to contain two enhancers. One of these enhance... | 4.96875 | bioscope | 1 |
The objectives of this study were to (1) determine the time course of neutrophil adhesion to monolayers of human umbilical vein endothelial cells (HUVECs) that were exposed to 60 minutes of anoxia followed by 30 to 600 minutes of reoxygenation and (2) define the mechanisms responsible for both the early (minutes) and l... | 5.09375 | bioscope | 1 |
AP-1, the polypeptide product of c-jun, recognizes and binds to specific DNA sequences and stimulates transcription of genes responsive to certain growth factors and phorbol esters such as 12-O-tetradecanoylphorbol-13-acetate (TPA). We studied the effects of TPA on the regulation of c-jun gene expression in HL-60 cells... | 5.125 | bioscope | 1 |
1,25-Dihydroxyvitamin D3 [1,25(OH)2D3] induces differentiation and inhibits proliferation of myeloid leukemic cells from various lines and patients; these effects are Little is known of expression of 1,25(OH)2D3 receptor RNA in hematopoietic cells. We examined the expression and modulation of expression of 1,25(OH)2D3... | 4.84375 | bioscope | 0 |
