ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect of thymic stromal lymphopoietin (TSLP) on transformation of dendritic cell (DC) and T cell in vitro.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSION</b>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.</p>
