ABSTRACT
Objective:
To explore the effects of miR-27a on the phenotype and cytokine secretion in LPS-stimulated dendritic cells.Methods:
Murine bone marrow-derived dendritic cells were transfected with miR-27a mimics and negative control mimics,and then stimulated by LPS for 24 hours.Dendritic cells exposed to LPS were collected for analysis of the DC immunophenotype by flow cy-tometry and supernatants were collected to determine cytokine lever.Moreover,the capability of stimulating allogeneic CD4 T+cell prolif -eration was measured by MLR ( mixed lymphocyte reaction) .Results:
The levels of MHCⅡ, CD80, and CD86 were significantly increased in LPS-stimulated dendritic cells when compared with imDC ( P<0.001).Transfection with miR-27a mimics resulted in sig-nificantly lower expression levels in levels of MHCⅡ,CD80,and CD86 (P<0.001).For cytokine secretion,transfection with miR-27a mimics enhanced IL-10 production (P<0.01) and reduced the production of IL-12 (P<0.05).For MLR,transfection with miR-27a mimics suppressed allogeneic CD4+T cell proliferation.Conclusion:
MiR-27a may play critical roles in regulating the maturation process and cytokine secretion in LPS-stimulated dendritic cells.
