Inguinal and popliteal LNC taken from mice 4 days after infection released low but significant (P < 0.05) levels of IL-4 in response to stimulation with SmCB1 or SmCL3 (Fig 4B) but only SmCB1 induced significant (P < 0.005) levels of IL-17 (Fig 4C) and IFN-γ (Fig 4D). This evidence concerns the gene IFNG and infection.
