BALF cytokine levels (mean ± SEM). Among proallergy cytokines, IL-5, IL-13, and Rantes were quantified. Among proinflammation cytokines, IL1α, IL-1β, IL-6, IFNγ, and TNFα were quantified. NC, negative control group; pollen, rats sensitized and challenged with 0.5 mg of pollen; unw-PCGs, rats sensitized and challenged with 4.5 × 107 unwashed PCGs; w-PCGs, rats sensitized and challenged with 4.5 × 107 washed PCGs; *, significantly different from NC (P <0.05); †, significantly different from the pollen group (P <0.05).
