In recent years a novel family of interferon (IFN)-inducible nuclear proteins has been identified in both mouse and humans and implicated in the control of myeloid differentiation. Recent evidence suggests that this role may be mediated by an effect on cell cycle regulation through interaction with known transcriptional regulators. Our laboratory first identified a nuclear protein designated IF...

Interleukin-12 (IL-12) is a monocyte/macrophage-derived cytokine that is critical for T lymphocyte and natural killer cell activities and functions. In this study, we examined the regulation of IL-12 expression by human monocytes in response to bacterial lipopolysaccharide (LPS). Several novel aspects of IL-12 induction from monocytes were shown. Optimal expression of IL-12 mRNA and bioactivity...

interferon gamma (ifn-γ) is one of the key cytokines in defining t helper 1 lymphocyte immuneresponses. in this study, the bovine ifn-γ gene was cloned from spleen tissue rna using the reversetranscription-polymerase chain reaction (rt-pcr). ifn-γ cdna was sub-cloned and expressed inmammalian expression plasmid (pcdna3.1(+)) under the control of the human cytomegalovirus (cmv)promoter. the pred...

BACKGROUND Interferon (IFN) beta-1a is an approved treatment for relapsing remitting multiple sclerosis (RRMS) and has been examined for use in secondary progressive multiple sclerosis (SPMS). However, no information regarding blood transcriptional changes induced by IFN treatment in SPMS patients is available. Our aim was to identify a subgroup of SPMS patients presenting a gene expression sig...

Tumor necrosis factor (TNF) and interleukin 1 are known to initiate endothelial vascular cell adhesion molecule (VCAM)-1 transcription primarily by activating nuclear factor (NF)-kappaB, which translocates to the nucleus. In addition to two NF-kappaB elements found within the minimal cytokine-inducible VCAM-1 promoter, an interferon-related factor (IRF) element (IRF-1) has been identified close...

In the present study, we demonstrate gamma-interferon (gamma-IFN)-inducible scavenger receptor A (SR-A) mRNA expression during the early stages of THP-1 and blood monocyte differentiation. Predominant induction of SR-A type II mRNA parallels the increased accumulation of cholesteryl esters under these conditions. A potential signal transducer and activator of transcription (STAT1) binding site ...

Objective(s): Protosappanin A (PrA) is an effective and major ingredient of Caesalpinia sappan L. The current study was aimed to explore the effect of PrA on atherosclerosis (AS). Materials and Methods: Firstly, the experimental model of AS was established in rabbits by two-month feeding of high fat diet. Then, the rabbits were randomly divided into five groups and treated with continuous high ...

OBJECTIVE To determine the prevalence of upregulation of interferon (IFN) type I inducible genes, the so called 'IFN type I signature', in CD14 monocytes in 69 patients with primary Sjögren's syndrome (pSS) and 44 healthy controls (HC) and correlate it with disease manifestations and expression of B cell activating factor (BAFF). METHODS Expression of IFI44L, IFI44, IFIT3, LY6E and MX1 was me...

Constitutive and inducible transcription of the major histocompatibility class II HLA-DRA gene involves the upstream S element and the conserved X and Y elements. In this report we have addressed the roles of spatial constraints and stereospecific alignment between the upstream S and X elements, and the X and Y elements, in both constitutive and interferon-gamma (gamma-IFN)-induced expression. ...

INTRODUCTION A hallmark of systemic autoimmune diseases like systemic lupus erythematosus (SLE) is the increased expression of interferon (IFN) type I inducible genes, so-called IFN type I signature. Recently, T-helper 17 subset (Th17 cells), which produces IL-17A, IL-17F, IL-21, and IL-22, has been implicated in SLE. As CCR6 enriches for Th17 cells, we used this approach to investigate whether...
