abstract：:5-oxo-6,8,11,14-eicosatetraenoic acid (5-oxo-ETE) is a metabolite of arachidonic acid formed by the oxidation of 5-hydroxy-6,8,11, 14-eicosatetraenoic acid by a highly specific dehydrogenase. 5-oxo-ETE is a chemoattractant for both neutrophils and eosinophils. Although it is not as effective as leukotriene B4 (LTB4) a...

In this study, we investigated whether IL-27 modulated the synthesis of CXCL10 in primary human lung fibroblasts (HLFs). HLFs were activated by IL-27 alone, or in combination with other cytokines....
