1 Histamine augments VCAM-1 expression on IL-4- and TNF-alpha-stimulated human umbilical vein endothelial cells. Histamine interleukin 4 Homo sapiens
2 We used immunocytochemical staining analysis to examine the effect of chemical mediators, including histamine, leukotrienes and platelet-activating factor (PAF), on VCAM-1 expression in IL-4- and TNF-alpha-stimulated endothelial cells. Histamine interleukin 4 Homo sapiens
3 Histamine, significantly augmented (p < 0.05 to p < 0.01) VCAM-1 expression in both IL-4- and TNF-alpha-stimulated endothelial cells. Histamine interleukin 4 Homo sapiens
4 IL-4 and TNF-alpha were found to have a synergistic effect on endothelial cell VCAM-1 expression, when compared with the effect of stimulation with each of these cytokines separately, and the addition of histamine further increased VCAM-1 expression. Histamine interleukin 4 Homo sapiens
5 These findings strongly suggest that histamine upregulates VCAM-1 expression at the transcriptional level through newly generated of mRNA in endothelial cells stimulated with IL-4 and TNF-alpha. Histamine interleukin 4 Homo sapiens
