ABSTRACT
Objective:
To investigate the effect of heat shock protein 60(HSP60) on the functions of dendritic cells of ApoE-/-mice (mDCs) in vitro by signal transduction of mitogen-activated protein kinase (MAPK) family mediated by Toll-like receptors (TLRs).Methods:
Myeloid mDCs were extracted in vitro from ApoE-/-mouse marrow,which were incubated as atherosclerotic animal model,and divided into three groupsHSP group,LPS group and control group.The three groups of mDCs were incubated to mature with mHSP60,LPS and normal saline,respectively and then examined the expression of TLR protein and mRNA by flow cytometry and real-time RT-PCR.In addition,the expression level of CD80 was examined by flow cytometry.The expression of MAPK family proteins was determined by Western blot analysis.The levels of cytokines secreted by mDCs,such as IL-6 and TNF-?,were analyzed by ELISA.Results:
The expression of TLRs and MAPK families (p38 and ERK) was increased in the samples of HSP group,when compared with control group (P0.05).Conclusion:
HSP60 is involved in activation of mDCs of atherosclerotic animal model by means of the signal transduction of MAPK family mediated by TLRs.
