Our results demonstrated that: (i) PGN induced phosphorylation of the transcription factors ATF-1 and CREB ; (ii) ATF-1 and CREB bound DNA as a dimer and induced transcriptional activation of a CRE reporter plasmid , which was inhibited by dominant negative CREB and ATF-1 ; (iii) PGN induced phosphorylation of c-Jun , protein synthesis of JunB and c-Fos , and transcriptional activation of the AP-1 reporter plasmid , which was inhibited by dominant negative c-Fos ; and (iv) PGN -induced activation of CREB /ATF and AP-1 was mediated through CD14 .
