Not exact matches

Th2 cytokines, like interleukin (IL) 4, IL - 5, and IL - 13, are involved in the production of IgE from B cells and are also elevated in the breast milk of allergic mothers (12).

Previous studies have shown that such vulnerability can lead to more frequent anxiety, and anxiety is known to activate a metabolic pathway responsible for the production of pro-inflammatory cytokines, signaling proteins that include interleukin - 6 (IL - 6).

Gut bacteria from MS patients also seemed to block the production of molecules, like the cytokine IL - 10, that reduce inflammation.

When cells that produced IL - 21 were put in culture with synovial fibroblasts (which are the main contributors to joint inflammation in rheumatoid arthritis), they induced the production of proinflammatory cytokines by these synovial fibroblasts, and cells that do not produce IL - 21, did not demonstrate this same outcome.

The scientists found that the IL - 17 and TNF cytokines were disrupting the pigment production of patients» melanocytes — the cells that produce melanin, the pigment that gives skin its color.

Dr. Wang plans to continue studying the effects of TNF and IL - 17 on melanocytes, and would like to expand the research to 3D skin models — fabricated samples of tissue in vitro that behave like human skin — that would give a better visual of how the melanin production process is being disrupted by these two cytokines during skin inflammation or wound healing.

Along with steroids, the mainstay of GVHD treatment today is drugs that turn down the production of IL - 2, a cytokine that helps T cell populations expand and diversify.

We have also have adopted a number of lines of study into the regulation of cytokine production and effector cell responses such, as cytotoxicity, in the response of Vα14 iNKT cells to glycolipid antigens or IL - 12 from activated DCs.

The Raf ‐ 1 kinase inhibitor protein participates in the pathogenesis of IL ‐ 17 ‐ mediated autoimmune diseases and inflammation by promoting the formation of the IL ‐ 17RA ‐ Act1 complex, required for downstream signaling and cytokine production.

Viral disease in Ifitm3 - / - mice was accompanied by elevated production of cytokines, most notably IL - 6.

This is a chemical messenger which regulates the production of many pro-inflammatory cytokines like TNF - a and IL - 6.

Probiotic supplementation has been shown to strengthen the activity of many cytokines — increasing interleukin (IL)-1 β and IL - 18 activates IFN - γ production from T, B, and Natural Killer Cells, which enhances phagocytosis (destruction) of pathogens.

It also tends to act in the body's production of IL - 10 if it is taken during infection, downregulating the levels of other cytokines and necessary, but if taken early in the disease process, it inhibits viral upregulation of IL - 10 and increases antiviral cytokine production and activity.»

LTB4 increases edema and chemotaxis, induces release of lysosomal enzymes, increases reactive oxygen species, and enhances production of the cytokines TNF - α, IL - 1, and IL - 6.»

Curcumin likewise suppresses production of monocyte chemoattractant protein - 1 (MCP - 1), interferon - inducible protein, tumor necrosis factor (TNF), and interleukin - 12 (IL - 12), cytokines which recruit or activate immune cells and perpetuate pro-inflammatory immune cascades (Chainani, 2003).

Studies suggest that the anti-inflammatory properties of melon are mainly related to its capacity to induce the production of interleukin 10 (IL - 10), an anti-inflammatory cytokine that affects immunoregulation and inflammation processes in the human body.

Although greater early local production of proinflammatory cytokines at wound sites is beneficial because it is associated with enhanced healing, greater systemic production of proinflammatory cytokines can represent a maladaptive response.24 Both physical and psychological stressors can provoke transient increases in plasma levels of proinflammatory cytokines, particularly IL - 6,25 as can negative emotions like depression and anxiety.26 - 28 More frequent or persistent stress - related changes have broad implications for physical and mental health; sustained elevated levels of proinflammatory cytokines have been linked to a variety of age - related diseases, including cardiovascular disease, osteoporosis, arthritis, type 2 diabetes mellitus, certain cancers, and frailty and functional decline.29 - 31

However, consistent with the differences between visits in wound healing, production of IL - 6, IL - 1β, and TNF - α increased more steeply between 4 and 22 hours following the social support interaction than after the conflict interaction, ending up higher at 22 hours at the first visit for all 3 cytokines (IL - 6, F2, 81 = 3.55; P =.03; IL - 1β, F2, 81 = 9.12; P <.001; TNF - α, F2, 81 = 3.56; P =.03).

The substantial increases in local cytokine production over time (Figure 2) have been assumed to be primarily a function of their local synthesis at the site by the cells that are migrating to the chamber.22, 58 In our data, correlations between cell numbers and cytokine levels at 22 hours after the social support interaction were r = 0.29 and P <.01 for IL - 6; r = 0.08 and P =.45 for TNF - α; and r = 0.13 for IL - 1β and after the conflict interaction, r = 0.52 and P <.001 for IL - 6 and r = 0.38 and P <.001 for both TNF - α and IL - 1β.

Prior work with the blister - chamber model showed that even modest levels of stress prior to wounding were reflected in lower production of proinflammatory cytokines at the wound site.21 Thus, the fact that the social support interaction always occurred at the first GCRC admission and yet wound healing and local IL - 6, TNF - α, and IL - 1β production were all poorer following conflict suggests that the effects of the disagreement were larger than our data suggest.
