Effects of Cang'erzi(Xanthium xanthii)-Containing Serum on Mast Cells Degranulation Induced by IgE and Infalmmatory Factors,PLCγ、PKC Expressions
摘要
Abstract
Objective:To investigate the effects of Xanthium xanthii-containing serum on degranulation of Mast Cells(MCs)byregulating PLCγ/PKCexpressions.Methods:RBL-2H3 cellswereroutinelyculturedand sensitized with IgE,experiment was divided into control group,model group,Xanthium xanthii-containing serum group and Ketotifen fumarate group(positive group)to receive corresponding drug intervention.Determination of calcium influx in the supernatant of RBL-2H3 cell culture medium by immunofluorescence staining.ELISA to detect changes in the levels of the inflammatory factors TNF-α,IL-6 release and β-aminohexosidase(β-Hex).Western blot was used to detect the expressions of phosphorylated T-cell-activated connexin(p-LAT),phosphorylated phosphodiesterase Cα1(p-PLCα1),and p-PKC proteins.Results:Compared with the control group,calcium influx,contents of TNF-α and IL-6,cell degranulation ability,fluorescence expression intensity of PKCα and protein expression levels of p-LAT,p-PLCα1 and p-PKC in model group were significantly increased(P<0.01).Compared with model group,calcium influx,TNF-α and IL-6 contents,cell degranulation ability and fluorescence expression intensity of PKCα in Xanthium xanthii-containing serum group and Ketotifen fumarate group were significantly decreased(P<0.01).The protein expression levels of p-LAT,p-PLCα1 and p-PKC were significantly decreased(P<0.05 or P<0.01).Conclusion:The Xanthium xanthii-containing serum can regulate MCs degranulation through PLCγ/PKC/Ca2+signaling pathway.关键词
