Following neutrophil stimulation with proinflammatory agonists (such as lipopolysaccharide [ LPS ], tumor necrosis factor-alpha [ TNF-alpha ], and fMet-Leu-Phe ) that induce the production of cytokines and chemokines in these cells, NF-kappaB /Rel proteins translocated to nuclear fractions , resulting in a transient induction of NF-kappaB DNA binding activity , as determined in gel mobility shift assays .
 ( protein: NF-kappaB, None) , ( protein: NF-kappaB /Rel proteins, None) , ( protein: tumor necrosis factor-alpha, None) , ( protein: NF-kappaB, None) , ( protein: chemokines, None) , ( protein: TNF-alpha, None) , ( protein: cytokines, None)
