Taken together, the findings of the present study are consistent with a role for NF-kappaB in the development of A/R tolerance (with respect to PMN adhesion ), perhaps by transcriptional regulation of GTP -cyclohydrolase .
 ( cell type: PMN, None) , ( protein: NF-kappaB, None) , ( protein: GTP -cyclohydrolase, None)
