IFN-γ, TNF-α, IL-4, and IL-10 levels as measured by ELISA.

Splenocytes prepared from LASW1 treated or control mice immunized with pRC/CMV-VP1 were cultured with 146S antigen (2 μg/ml). The concentrations of (A) IFN-γ, (B) TNF-α, (C) IL-4 and (D) IL-10 in culture supernatants were measured at 48 h. Bars represent the mean ± SD of triplicate wells. *P<0.05, **P<0.01.
