Interferon regulatory factor 4 negatively regulates the production of proinflammatory cytokines by macrophages in response to LPS.
A member of the IFN regulatory factor (IRF) family of transcription factors, IRF-4 is expressed in lymphocytes and macrophage/dendritic cells. Studies using IRF-4-deficient mice have revealed the critical roles of IRF-4 in lymphocyte responses. However, the role of IRF-4 in innate immune responses is not clearly understood. Here, we demonstrate that IRF-4 negatively regulates the production of ...
متن کاملIL-21 Modulates Release of Proinflammatory Cytokines in LPS-Stimulated Macrophages through Distinct Signaling Pathways
The aim of this study was to investigate the anti-inflammatory effect of IL-21 on LPS-induced mouse peritoneal macrophages. The results showed that IL-21 significantly inhibited LPS-induced mRNA expression of IL-1β, TNF-α, and IL-6 in macrophages, but not of IFN-γ, IL-10, CCL5, or CXCL2. ELISA analysis showed that IL-21 also suppressed LPS-induced production of TNF-α and IL-6 in culture superna...
متن کاملANG II is involved in the LPS-induced production of proinflammatory cytokines in dehydrated rats.
We have previously reported results that led us to speculate that ANG II is involved in the LPS-induced production of proinflammatory cytokines, especially under dehydrated conditions. To test this possibility, in this study we examined the effects of an angiotensin-converting enzyme (ACE) inhibitor and an antagonist of the type-1 ANG II receptor (AT(1) receptor) on the LPS-induced production o...
متن کاملHerbal medicine IMOD suppresses LPS-induced production of proinflammatory cytokines in human dendritic cells
Traditional medicines that stimulate or modulate the immune system can be used as innovative approaches to treat immunological diseases. The herbal medicine IMOD has been shown to strongly modulate immune responses in several animal studies as well as in clinical trials. However, little is known about the mechanisms of IMOD to modulate immunity. Here we have investigated whether IMOD modulates ...
متن کاملThe IL-1 family member 7b translocates to the nucleus and down-regulates proinflammatory cytokines.
The IL-1 family member 7b (IL-1F7b) is a novel homolog of the IL-1 cytokine family discovered by computational cloning. We have reported that IL-1F7b shares critical amino acid residues with IL-18 and binds the IL-18-binding protein; in doing so, IL-1F7b augments the inhibition of IFN-gamma by the IL-18-binding protein. IL-1F7b also binds IL-18Ralpha but neither induces signal nor acts as a rec...
