1 Tetramethylpyrazine suppresses interleukin-8 expression in LPS-stimulated human umbilical vein endothelial cell by blocking ERK, p38 and nulear factor-kappaB signaling pathways. tetramethylpyrazine C-X-C motif chemokine ligand 8 Homo sapiens
2 AIM OF THE STUDY: To determine the anti-inflammatory effects of Tetramethylpyrazine (TMP) and to investigate the inhibitory effect of TMP on IL-8 production in human umbilical vein endothelial cells (HUVECs) induced by LPS might be mediated by inhibiting p38, ERK and NF-kappaB signaling pathways. tetramethylpyrazine C-X-C motif chemokine ligand 8 Homo sapiens
3 RESULTS: TMP inhibits LPS-induced IL-8 production in HUVECs at both the protein and mRNA levels, suggesting that TMP has an antiinflammatory effect on endothelial cells. tetramethylpyrazine C-X-C motif chemokine ligand 8 Homo sapiens
4 RESULTS: TMP inhibits LPS-induced IL-8 production in HUVECs at both the protein and mRNA levels, suggesting that TMP has an antiinflammatory effect on endothelial cells. tetramethylpyrazine C-X-C motif chemokine ligand 8 Homo sapiens
5 CONCLUSIONS: The inhibitory effect of TMP on the LPS-induced IL-8 production is mediated by the NF-kappaB-dependent pathway, and TMP also separately affects the ERK and p38 MAPK pathway. tetramethylpyrazine C-X-C motif chemokine ligand 8 Homo sapiens
