IFN-γ and IL-4 secretion by abomasal lymph node lymphocytes following stimulation with Teladorsagia circumcincta L4 or adult somatic antigen from Canaria Hair Breed and Canaria Sheep vaccinated with a prototype recombinant sub-unit T. circumcincta vaccine and subsequently challenged with T. circumcincta. IFN-γ (A) and IL-4 (B) secretion was examined in supernatants collected 4 days post-stimulation of abomasal lymph node lymphocytes with 5 g/mL of T. circumcincta L4 or adult somatic antigen. Data are expressed as the concentration of the cytokine release in picograms per mL (pg/mL). Results are shown as the mean values with error bars indicating ± SE. “*” denotes statistical significance for p < 0.05 when compared to media only secretion.
