Figure 1From: Oral administration of PPC enhances antigen-specific CD8+ T cell responses while reducing IgE levels in sensitized mice Reduction of basal IgE in naïve mice. Naïve Balb/c mice (n = 4/group) were provided water or 200 μg/mL PPC ad libitum for 14 days. The serum levels of total IgE were measured by ELISA. PPC suppressed the development of IgE (** represents a p < 0.01). Error bars represent the standard deviation.Back to article page
