Effects of Shenqi on protein expression of T-bet, GATA3, p-STAT6, and SOCS1 in OVA-stimulated lymphocytes. Primary spleen lymphocytes isolated from Wistar rats were preincubated in the presence or absence of Shenqi (50, 100, and 200 μg/mL) or Loratadine (5 μM) for 1 h and then cultured with OVA for another 72 h. The total cell proteins were extracted to detect the expression of Th1 regulating factor T-bet (A); Th2 regulating factor GATA3 (B) and phosphor-STAT6 (C), as well as the negative regulator SOCS1 (D) via Western blot. The data are presented as the means ± SEM of three independent experiments, #

p < 0.01 vs. cells alone, * p < 0.05, ** p < 0.01, and *** p < 0.001 vs. OVA-treated cells.
