Objective: To investigate the effect of heat shock protein 10 (HSP10) of Chlamydophila pneumoniae in inducing TNF-α on THP-1 cells and the roles of TLR4 and TLR2 involved in it. Methods: Purified native recombinant HSP10 from Cpn(CHSP10) were produced and inactivated the endotoxin contamination, then different concentration (0.5,1,5,10,20,30 μg/ml) of CHSP10 were used to stimulate THP-1 for different time (0,6,12,24,36,48,60 h). TNF-α were measured by using human TNF-α ELISA kit and compared among different groups. THP-1 were collected and ...
