Effects of Chlamydia pneumoniae infection and hyperlipidemia on the expression of NF-?B and AP-1 in myocardium / 中国病理生理杂志

ABSTRACT

AIM: To investigate the effects of Chlamydia pneumoniae infection and hyperlipidemia on the expression of NF-?B and AP-1 in the myocardium. METHODS: The indirect immunofluorescence method was used to examine wild C57BL/6J mice infected with Chlamydia pneumoniae and fed with an atherogenic diet. The expression of the subunit of NF-?B, P50, and c-Fos in the murine myocardium was observed. RESULTS: Chlamydia pneumoniae infection and hyperlipidemia induced the activation of NF-?B and AP-1 in murine myocardium. P50 and c-Fos were not detected in the controls, but there were different levels of positive expression in the experiments (P
