Sel1L对小鼠骨髓源树突状细胞的影响
Effects of Sel1L on properties of bone marrow derived dendritic cells
摘要
Abstract
Objective:To explore the effects of suppress or enhancer of lin-12-like(Sel1L) on differentiation and function of bone marrow-derived dendritic cells.Methods:To generate conditional knockout mice by the Cre-Loxp recombination system.ELISA and Real-time fluorescence quantitative PCR(RT-PCR) was used for analyzing the protein levels and mRNA levels of IL-6/IL-12 in BMDCs.The protein levels of Sel1L in BMDCs were detected by Western bolt.The expression of CFSE,CD80,CD86,MHC-Ⅰ,MHC-Ⅱon BMDCs and the capability in priming OVA specific CD4+T cells proliferation were analyzed by the flow cytometry.Results:The deficiency of Sel1L decreases the proliferation of DCs during its differentiation,up-regulates the secretion of IL-6,IL-12 and the expression of MHC-Ⅰ.Notably,Sel1L-null DCs was failed to up-regulate MHC-Ⅱexpression and dramatically impaired their ability to prime OVA323-339specific CD4+T cell.Conclusion:The deletion of Sel1L can reduce the proliferation of BMDCs and down-regulate its ability in priming the proliferation of OVA specific CD4+T cells.关键词
