The effect of LPS stimulation on NFAT2 and HMGB1 interaction in the cytoplasm was observed by immunoprecipitation assay. HMGB1 production and release was detected in cells with specific small interfering RNA (siRNA)-mediated suppression of NFAT2 expression. Results LPS stimulated HMGB1 release from THP-1 cells. As LPS stimulation prolonged ...

VIVIT attenuated LPS or LPS plus IFN-γ induced IL-12 p40 mRNA and protein expression in bone marrow derived macrophages (BMDMs) and reduced DNA binding of NFAT to a composite NFAT–interferon stimulated response element (ISRE) on the Il12b promoter. In addition, VIVIT inhibited the production of NO and the secretion of IL-12 p70, IL-23, and ...

2014年1月30日 · CD14 was also shown to induce Ca 2+ influx and NFAT activation causing apoptosis of differentiated DCs, but not macrophages, stimulated by LPS. NFAT2/c1 activated by the receptor activator of NF-κB (RANKL) was also shown to play a key regulatory role in the terminal differentiation of osteoclasts.

2012年8月16日 · Numerous studies have demonstrated that LPS binding to CD14 is enhanced by LPS binding protein, which is followed by CD14-mediated transfer of LPS to the TLR4/MD2 complex and subsequent activation of the intracellular cascade through adaptors MyD88-TIRAP and TRAM-TRIF.
Nuclear Factor of Activated T Cells 2 Transactivation in Mast Cells
The presence of the β-specific sequence is associated with both quantitative and qualitative differences in transactivation ability: NFAT2.β demonstrates a greater ability to transactivate in response to both PMA/ionomycin and LPS over a range of …
