Ginseng enhances IFN-γ cytokine-producing lung cells from BALB/c mice. (A) IL-4 ELISpot. (B) IFN-γ ELISpot. Cytokine (IL-4 and IFN-γ) producing lung cells isolated at day 5 postinfection (n=5 BALB/c mice per group) were determined by ELISpot after stimulation with FI-RSV (2 μg/mL), RSV F peptide (4 μg/mL) or RSV G peptide (4 μg/mL). The spots for cytokine-producing cells from the lung were counted and expressed based on 1×10⁶ lung cells. The group labeling and treatments are the same as in the Fig. 2. Data were collected from 2 independent experiments (n=5). Values are the mean±SEM. *P<0.05; **P<0.01; ***P<0.001. IFN, interferon; IL, interleukin.
