The role of inflammation in coronary artery ectasia (CAE) remains controversial. We evaluated the hypothesis that CAE might be associated with a specific pattern of T helper (Th) lymphocyte activation by measuring the Th-1 cytokine, interleukin-2 (IL-2) and the Th-2 cytokines, interleukin-4 (IL-4) and interleukin-6 (IL-6) in patients with CAE, obstructive coronary artery disease (CAD) and controls...
Gamma irradiation of tissues and organs leads to many pathological consequences due to the formation of reactive oxygen species, DNA damage and the subsequent massive death of cells. The therapeutic use of gamma irradiation in the treatment of cancer is based on its penetrating power and damaging effects on tumor cells. Other effects from the irradiation are unnoticeable in comparison. Moreover, the...
AD patients exhibit sensitisation to multiple allergens due to a Th1/Th2 imbalance. Until now, it was impossible to improve the polysensitised status and elevated serum total IgE levels. In this study, the effects of IFN-gamma on systemic polysensitisation to multiple allergens and on serum total IgE levels are investigated.A total of 44 AD patients whose food allergies were completely controlled...
Atherosclerosis is an inflammatory disease of the vasculature regulated by cytokines. Macrophages play a crucial role at all stages of this disease, including regulation of foam cell formation, the inflammatory response and stability of atherosclerotic plaques. For example, matrix metalloproteinases produced by macrophages play an important role in modulating plaque stability. More recently, the ADAMTS...
The macrophage is essential to the innate immune response, but also contributes to human disease by aggravating inflammation. Under severe inflammation, macrophages and other immune cells over-produce immune mediators, including vascular endothelial growth factor (VEGF). The VEGF protein stimulates macrophage activation and induces macrophage migration. A natural inhibitor of VEGF, the soluble VEGF...
Interleukin 17 (IL-17) as one of the pro-inflammatory cytokines is a very important player in the immune response to many pathogens and seems to play a role also in certain chronic and autoimmune diseases. Many studies showing the importance of this cytokine were conducted on murine models and human patients. In recent years, some experiments with other animals in which interleukin-17 was measured...
Interleukin-10 (IL-10) is an important immunomodulatory cytokine that plays an obligate role in regulating inflammatory responses. Here we demonstrated the role of IL-10 in regulating crypts length and breadth as well as maintaining the survival of epithelial cells using rhesus colon explant cultures. Anti-IL-10 antibody treatment of colon explant cultures induced increased production of inflammatory...
We previously revealed that endogenous bone morphogenetic protein (Bmp) activity is required for lipid accumulation in 3T3-L1 adipocytes. The present study characterized the role of endogenous Bmp activity in preadipocytes. Endogenous Bmp activity was monitored by analyzing the level of phosphorylation of Smad1/5/8, downstream molecules in the Bmp pathway. Higher levels of phosphorylated Smad1/5/8...
Cancer-cachexia causes severe weight loss, particularly from the wasting of skeletal muscle, which occurs due to increased protein catabolism and/or decreased protein synthesis. The muscle protein degradation observed in cancer patients is mediated by a specific cytokine, proteolysis-inducing factor (PIF), which is produced by the tumour. This protein increases the ubiquitin–proteasome pathway activity,...
During intestinal inflammation TNFα levels are increased and as a consequence malabsorption of nutrients may occur. We have previously demonstrated that TNFα inhibits galactose, fructose and leucine intestinal absorption in animal models. In continuation with our work, the purpose of the present study was to investigate in the human intestinal epithelial cell line Caco-2, the effect of TNFα on sugar...
In contrast to the well known immunostimulatory roles of IL-12, little has been known about its immunosuppressive roles. In the present study, IL-12-activated lymphocyte-mediated macrophage apoptosis was investigated by employing murine lymphocyte/macrophage cocultures. IL-12-activated lymphocytes and their culture supernatants induced an inducible nitric oxide synthase (iNOS)-mediated nitric oxide...
There are still controversies whether insulin resistance (IR) develops in preterm born children during early childhood.To investigate the role of leptin, soluble leptin receptor (sOB-R), adiponectin, visfatin and insulin sensitivity in the pathogenesis of possible IR in preterm born children during early childhood.Twenty-nine preterm small for gestational age (SGA) born children (Group 1) and 25 preterm...
Approximately 5–10% of subjects with prediabetes become diabetic every year. Inflammation is involved in the development of obesity-related type 2 diabetes (T2D). However, to date, the relationship between inflammation and prediabetes, defined by hemoglobin A1c (HbA1c) ⩾5.7 and <6.5%, remains largely unexplored, especially in African Americans. Therefore, in this study we examined a comprehensive...
We conducted a study to test the hypothesis that systemic dysregulation of Th1/Th2 cytokine levels was associated with detection of carcinogenic or overall human papillomavirus (HPV) at the cervix among 964 women residing in a rural village in Nigeria.Levels in plasma were measured for 19 cytokines, including Th1-like cytokines IL-2, IL-12 (p40), TNF-a, IFN-g; Th2-like cytokines IL-4, IL-5, IL-6,...
IL-32 has been previously shown to promote inflammation in rheumatoid arthritis patients and to contribute to IL-1β-induced ICAM-1 as well as other proinflammatory cytokines synthesis in human umbilical endothelial cells (HUVECs). Given the high rate of atherosclerosis in RA, these observations suggest that IL-32 may be involved in the inflammatory pathways of atherosclerosis.mRNA and protein levels...
Many cytokine receptors are cell surface proteins that promiscuously combine to form active signalling homo- or heterodimers. Thus, receptor chain dimerization can be viewed as a direct measure of a high probability of intracellular signalling by specific cytokines. Proximity ligation assay (PLA) is an antibody-based method for selective and highly sensitive detection of protein interactions by microscopy...
Infections are common in preterm infants and cause differences in cytokine levels. Aim of this study was to measure cytokine levels in preterm infants during the first year of life and to determine the effect of feeding a specific non-digestible carbohydrate mixture (scGOS/lcFOS/pAOS). Furthermore, other perinatal factors in relation to these cytokine levels were analysed.In a randomized controlled...
Low grade inflammation is one of the major metabolic disorders in case of obesity due to variable secretion of adipose derived cytokines called adipokines. Recently the nuclear protein HMGB1 was identified as an inflammatory alarmin in obesity associated diseases. However HMGB1 role in adipose tissue inflammation is not yet studied.The aim of this study was to prove the expression of HMGB1 in human...
