interleukin (il)-17 is exclusively produced by cd4 helper t-cells upon activation. it most often acts as a pro-inflammatory cytokine, which stimulates the release of pro-inflammatory cytokines il-6, il-8, tnf-α, and granulocyte-macrophage colony-stimulating factor (gm-csf). in this study, we studied the in-vitro il-17 response to specific antigens and a variety of mitogens and compared the il-1...

atopic dermatitis (ad) is a common chronically relapsing skin disease associated with abnormal cytokine production, and activation of t-helper 2 cells. the aim if this study was to determine whether cytokine gene polymorphisms might influence the development of ad. single nucleotide polymorphisms in the genes for i-l1alpha, il-1beta, il-1r, il-2, il-4, il-6, il-10, il-12, tgf beta, tnf and ifng...

Background & Aims: While iodine is an essential element for the synthesis of thyroid hormones, epidemiological studies have showed that excessive iodine intake leads to autoimmune thyroid diseases, with an unknown mechanism. Previous studies have showed disturbance in the circulating cytokines could lead to autoimmune diseases. To determine the role of iodine in cytokine production and devel...

objective: aflatoxin b1 (afb1) suppresses the immune system. to decrease such suppressive effects on the immune system, a wide range of herbal medicines like garlic are utilized. biological activities of garlic in vitro and in vivo have also been verified. our previous studies demonstrated that aged garlic (dry garlic bulbs preserved in the freezer for six months at -20˚c) have increased immuno...

The potential influence of magnesium (Mg) on inflammatory responses was assessed using an ex vivo model--human whole blood incubated with and without lipopolysaccharide (LPS). Addition of LPS leads to higher levels of cytokines including TNF-alpha and IL-6. No significant effect of Mg was observed following LPS stimulation whereas high concentration of Mg inhibited the baseline level (without L...

Human rhinoviruses (HRV) are a major cause of exacerbations of airways disease. Aspects of cell signalling responses to HRV infection remain unclear, particularly with regard to signalling via PI3K, and the PI3K-dependent pathway, autophagy. We investigated the roles of PI3K and autophagy in the responses of epithelial cells to major and minor group HRV infection. The PI3K inhibitor 3-MA, commo...

Synovial tissue of patients with rheumatoid arthritis (RA) spontaneously produces several cytokines, of which a fundamental role in joint inflammation and destruction has been established. However, the factors sustaining this phenomenon remain poorly understood. In a recent report, blockade of Toll-like receptor 2 (TLR2) was found to inhibit the spontaneous release of inflammatory cytokines by ...
