Interleukin 1beta(IL-1beta), a proinflammatory cytokine, is related with inflammatory diseases and it up-regulates MUC2 gene expression and mucin secretion. This study was designed to investigate the signal transduction pathway of the IL-1beta-mediated MUC2 gene expression and mucin secretion in human airway epithelial cells. In cultured human airway NCI-H292 epithelial cells, the steady state ...

OBJECTIVE To investigate the patterns of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), IL-6, interferon-gamma (IFN-gamma) and interleukin-1 receptor antagonist (IL-1Ra) during the course of dengue shock syndrome. DESIGN Prospective clinical study. SETTING Pediatric Intensive Care Unit, Dr. Kariadi Hospital, the university hospital of Diponegoro University, Semarang,...

There is evidence that proinflammation may be linked to the development of hypertension (HT). We examined the association of both the interleukin-1 beta (IL-1beta) and the interleukin 1-receptor antagonist (IL-1ra) with future blood pressure (BP) and HT occurrence (BP >or= 140/90 mmHg, or antihypertensive drug) in a population-based prospective study. Our study consisted of 396 (147 men and 249...

Interleukin (IL)-1beta is a proinflammatory cytokine that elicits the majority of its biological activity extracellularly, but the lack of a secretory signal sequence prevents its export via classic secretory pathways. Efficient externalization of IL-1beta in macrophages and monocytes can occur via stimulation of P2X7 nucleotide receptors with extracellular ATP. However, the exact mechanisms by...

Granulocyte macrophage-colony stimulating factor (GM-CSF) has immuno-stimulatory effects. We hypothesized that GM-CSF plays an important role both in lipopolysaccharide (LPS)- and hemorrhage-induced acute lung injury (ALI). We also postulated that GM-CSF augments LPS-induced inflammation by priming neutrophils. ALI was induced in GM-CSF-/- or control C57BL mice either by LPS injection or by hem...

The purpose of the present study was to examine the profile of selected proinflammatory cytokines in maternal serum of first-trimester pregnancies complicated by threatened abortion (TACP) and its relevance to obstetric outcome. Serum levels of Th1-type cytokines interleukin-1beta (IL-1beta), tumor necrosis factor alpha (TNF-alpha), and Th2-type cytokine interleukin 6 (IL-6) were measured, by E...
