Abstract:
Objective:To show whether the Fas Ligand gene induces mast cells apoptosis.Methods:RT-PCR was used to amplify the gene of rat Fas ligand extracelluar domain and transmembrane domain and cloned it into eukaryotic expression plasmid pcDNA3.1.Transcent transfect RBL-2H3,the expression of Fas ligand RBL-2H3 was detected by RT-PCR、Western blot.The Annexin V FCM was used to detect the RBL-2H3 apoptosis after the transfection of Fas Ligand.Results:It is successful to obtain the gene of rat Fas Ligand extracellular domain and transmembrane segment,cloning it into pcDNA3.1,FasL was expressed on the surface of RBL-2H3 and it's supernatant after the transfection of pcDNA3.1/FasL.The cell start to be apoptosis.Conclusion:Our study reveals that Fas Ligand gene transfection in RBL-2H3 can effectively induced apoptosis.It is a promising strategy for Fas Ligand to be used in the therapy of allergic disease.
