Pathological processes involved in the initiation of rheumatoid synovitis remain unclear. We undertook the present study to identify immune and stromal processes that are present soon after the clinical onset of rheumatoid arthritis (RA) by assessing a panel of T cell, macrophage, and stromal cell related cytokines and chemokines in the synovial fluid of patients with early synovitis. Synovial ...

BACKGROUND Obesity is characterized by a low grade chronic inflammation state. Indeed circulating pro-inflammatory cytokines, such as TNF-α and IL-6, are elevated in obese subjects, while anti-inflammatory cytokines, such as IL-10, appear to be reduced. Cytokines profile improves after weight loss, but how visceral or subcutaneous fat loss respectively affect pro- or anti-inflammatory cytokines...

We have previously described that boosted natural xenoantibodies in rats cross-react to bacteria by targeting carbohydrate antigens. This type of immunization is associated with reduced survival after cecal ligation and puncture (CLP). In the present study, we investigated further this phenomenon by immunizing Lewis rats with three intraperitoneal injections, every other day, of hamster blood c...

We describe immune phenotypes (innate and adaptive cytokines) according to environmental exposure using latent class analysis. A total of 310 schoolchildren living in Ecuador were assayed for spontaneous cytokine production as well as mitogen (SEB)-stimulated cytokines in whole blood cultures. We collected data on environmental exposures by questionnaire and on intestinal parasites by examinati...

BACKGROUND & AIMS condition of hypoxia caused by hypertrophy of adipose cells in obesity triggers macrophages recruitment and production of cytokines. Additionally, high consumption of saturated fatty acids (SFA) and high glycemic index meals may contribute to oxidative stress and chronic low-grade inflammation by increases NF-kB activation. Thus, the aim of the study was to analyze the contrib...

antifibrotic therapies should preferentially be targeted to the activated hepatic mesenchymal cells. those cells resemble wound healing myofibroblasts and synthesize an excess of extracellular matrix (ecm) proteins. they derive from quiescent hepatic stellate cells (hsc) and portal/perivascular (myo-) fibroblasts (mf). whereas various agents have been shown to inhibit hsc/mf proliferation and c...

background depression and sleep disorders are more prevalent among rotational shift workers than regular day workers. people with sleep disorders have higher inflammatory and pre-inflammatory cytokines than those in the control group. objectives the present study was conducted to investigate serum level of high sensitivity c-reactive protein (hscrp), interleukin-6 (il-6) and cortisol among depr...
