  1. Groups of female BALB/c mice (n = 5) were immunized with AFCo1 by the i.n route (3 doses, 12.5µL in each nostril) with a 7 day interval. Anti-PLn IgA in saliva or serum and anti-PLn IgG and IgG subclass induction by AFCo1 and IFN-γ production by spleen cells from immunized mice. Phosphate Buffer was used for the Placebo group. IFN-γ concentration was evaluated in splenocyte supernatants, 7 days after the last dose and stimulated in vitro with PLn or phytohaemagglutinin (PHA). Asterisks denote significant differences between groups * p<0.05.
