ABSTRACT
AIM:
To explore the expression of CD14 in rat Kupffer cells (KCs).METHODS:
In rat KCs induced by LPS or the mediators from KCs induced by LPS,the changes of CD14 expression were measured by RT-PCR and immunohistochemistry.The expressions of TNF? mRNA?IL-6 mRNA or the concentrations of TNF??IL-6 were estimated by in situ hybridization and radioimmunoassay,respectively.RESULTS:
LPS increased the expression of CD14 in KCs in a dose-dependent fashion (LPS,1 ?g/L-10 mg/L) and in a time-dependent fashion(0.5 h-24 h,peaked at 3-6 hours). While the expression of CD14 in KCs stimulated by the active mediators from KCs which had been exposed to LPS 1 hour were obviously increased.CONCLUSIONS:
There was a close relationship between LPS or the active mediators from KCs induced by LPS and the expressions of CD14. It is implied that the increase in CD14 expression may be induced by LPS and the cytokines produced by KCs,it also reveals that there is a auto-regulated loop in CD14 expression.
