As AP-1 activity is regulated in part by activation of the c-Jun N-terminal kinase ( JNK ), which phosphorylates and subsequently increases the transcriptional activity of c-Jun, we examined whether LPS treatment of macrophages resulted in activation of this kinase .
 cell type: macrophages; protein: kinase; protein: c-Jun N-terminal kinase; protein: JNK; protein: AP-1
