Mice with established lesions were injected perilesionally twice a week for 2 weeks with PBS, 64 μg CpG-NP, dose-matched free CpG (93 ng) or 64 μg empty NP. Two days after the end of treatment, dLN cells were harvested and stimulated with Soluble Leishmania Antigen (SLA) and (A) IFNγ, (B) IL-17, (C) IL-10 and (D) IL-13 levels were determined by ELISA.
