In order to elucidate possible mechanisms underlying endothelial cell activation by xenogeneic serum , we focussed on transcription factor NF-kappa B , a central regulator for the induction of different genes, including adhesive molecules and chemoattractants .
 ( protein: NF-kappa B, None) , ( protein: chemoattractants, None) , ( protein: transcription factor NF-kappa B, None) , ( cell type: endothelial cell, None) , ( protein: adhesive molecules, None)
