PT extract inhibits the secretion of IL-4, IL-5, IL-13, and eotaxin in mouse splenocytes. Splenocytes were isolated from NC/Nga mice of the untreated, control (Con), and PT groups. Subsequently, the cells were treated with 1 μg/mL concanavalin A for 24 h and 48 h. Supernatants were collected and analyzed by ELISA. Data are presented as means ± SD with statistical significance as *P < 0.05 and **P < 0.01 between the untreated and control groups or between the control and PT-treated groups.
