1 Histamine-induced IL-6 and IL-8 production are differentially modulated by IFN-gamma and IL-4 in human keratinocytes. Histamine C-X-C motif chemokine ligand 8 Homo sapiens
2 We therefore examined the capacity of histamine to modulate the production of interleukin (IL)-6 and IL-8 by keratinocytes. Histamine C-X-C motif chemokine ligand 8 Homo sapiens
3 We found that histamine significantly augmented the production of IL-6 and IL-8 in a dose- and time-dependent manner. Histamine C-X-C motif chemokine ligand 8 Homo sapiens
4 The histamine-induced up-regulation of IL-6 and IL-8 production, however, was completely abrogated by a combination of pyrilamine and cimetidine. Histamine C-X-C motif chemokine ligand 8 Homo sapiens
5 On the other hand, the production of IL-8 was inhibited by IFN-gamma, and IFN-gamma and IL-4 both completely abrogated the histamine-induced IL-8 production. Histamine C-X-C motif chemokine ligand 8 Homo sapiens
6 On the other hand, the production of IL-8 was inhibited by IFN-gamma, and IFN-gamma and IL-4 both completely abrogated the histamine-induced IL-8 production. Histamine C-X-C motif chemokine ligand 8 Homo sapiens
7 These results suggest that the histamine-induced IL-6 production and IL-8 production are differentially regulated by IFN-gamma and IL-4. Histamine C-X-C motif chemokine ligand 8 Homo sapiens
