Acute psychosocial stress stimulates transient increases in circulating pro-inflammatory plasma cytokines, but little is known about stress effects on anti-inflammatory cytokines or underlying mechanisms. We investigated the stress kinetics and interrelations of pro- and anti-inflammatory measures on the transcriptional and protein level. Forty-five healthy men were randomly assigned to either ...

Epilepsy is a neurological disorder affecting almost 1% of the world population. Experimental human and animal studies suggest that inflammation mediators, like cytokines, participate in the physiopathology of epilepsy. Interleukin-1beta (IL-1ß) could influence susceptibility for seizures, as well as neuronal death caused by seizures, although some findings are contradictory. This document revi...

BACKGROUND Previous studies by us and other have provided evidence that leukocytes play a critical role in the development of diabetic retinopathy, suggesting a possible role of the innate immune system in development of the retinopathy. Since MyD88 is a convergence point for signaling pathways of the innate immune system (including Toll-Like Receptors (TLRs) and interleukin-1ß (IL-1ß)), the pu...

Synovial membranes are formed by four main types of cells, i.e. fibroblasts, macrophages, epitheliocytes and adipocytes. To study the combined effect of various factors on these cell populations, synovial membranes dissected from rat knee joints were incubated in control medium or medium with lipopolysaccharide (LPS), TNF, TGF-ß1 or IL-4 for 12 h. LPS stimulated TNF secretion and both agents st...

Objective: To investigate the effects of avocado (A)/soybean (S) unsaponifiables on the metabolism of human osteoarthritic (OA) chondrocytes cultured in alginate beads over 12 days. Methods: Enzymatically isolated OA chondrocytes were cultured in alginate beads in a well defined culture medium for 12 days, in the presence or not of 10 10 M interleukin 1ß (IL-1ß). DNA content was measured using ...

Loss of expression of surface antigens represents a significant problem for cancer immunotherapy. Microphthalmia-associated transcription factor (MITF-M) regulates melanocyte fate by driving expression of many differentiation genes, whose protein products can be recognized by cytolytic T lymphocytes. We previously reported that interleukin-1ß (IL-1ß) can downregulate MITF-M levels. Here we show...

BACKGROUND Patients with type 2 diabetes present with an accelerated atherosclerotic process. Animal evidence indicates that dipeptidyl peptidase-4 inhibitors (gliptins) have anti-inflammatory and anti-atherosclerotic effects, yet clinical data are scarcely available. DESIGN AND METHODS A prospective, randomized, open-label study was performed in 60 patients with coronary artery disease (CAD)...

AIMS Previous study on association between pro-inflammatory cytokines and mortality in PD population is limited. We aimed to investigate here. METHODS Total 50 patients who underwent incident PD were enrolled in this study. We measured the titers of pro-inflammatory cytokines Interleukin-18(IL-18), Interleukin-6 (IL-6), and Interleukin-1ß (IL-1ß). Study outcomes were all-cause mortality, card...

OBJECTIVE Coronary slow flow phenomenon (CSFP) is characterized by the decreased rate of contrast progression in epicardial coronary arteries in the absence of significant coronary stenosis. Mounting evidence has showed a significant association between inflammation and CSFP severity. This study aimed to evaluate possible associations between interleukin-1 receptor antagonist (IL-1ra) gene vari...

introduction: immune system is involved in the etiology and pathophysiology of inflammation and vitamins are important sources of substances inducing nonspecific immunomodulatory effects. given the proinflammatory role of cytokines in the inflammation and pain induction, this study aimed to assess the effects of long-term administration of vitamin b1 on the proinflammatory cytokines, edema, and...
