Here, we studied whether PPARalpha activation (by means of the selective agonist WY 14,643 ) of endothelial cells , pivotal in the regulation of inflammatory responses, interfered with LTB4 induced adhesion of PMN neutrophil granulocytes in vitro.
 ( protein: PPARalpha, None) , ( cell type: PMN neutrophil granulocytes, None) , ( cell type: endothelial cells, None)
