Abstract:
Objective To explore the effect of thymic stromal lymphopoietin (TSLP) on transformation of dendritic cell (DC) and T cell in vitro.Methods Mouse-derived immature dendritic cells and T lymphocytes were co-cultured in vitro,which were divided into 4 groups (TSLP stimulation group,TSLP stimulation and its receptor blocking group,ovalbumin stimulation group and ovalbumin stimulation and TSLP receptor blocking group).IL-4,IL-8 and IFN-β in cell culture supernatant were detected after 2 days by ELISA.SPSS 13.0 software was used to analyze the data.Results IL-4 levels of TSLP receptor blocking groups [(48.84 ± 1.56) pg/ml,(52.53 ± 2.36) pg/ml] were significantly lower than those of corresponding TSLP stimulation group and ovalbumin stimulation group [(72.55 ± 7.76) pg/ml,(80.47 ± 21.93) pg/ml ; t =5.994,P < 0.05 ; t =2.534,P < 0.05].However,there were not significant differences of IL-8 and IFN-β expression between corresponding two groups of whether or not TSLP receptor blocking (all P > 0.05).Conclusion TSLP receptor blockade in vitro can inhibit T lymphocyte transformation to Th2,which may provide a new therapeutic strategy for clinical Th2 dominant diseases such as allergic rhinitis and asthma.
