Cytokine release in splenocyte-culture supernatant upon in vitro stimulation with H1 antigen.
Notes: Six weeks after immunization, spleens were isolated from mice (n=3) from each group and cultured. IFNγ, TNFα, IL4, and IL10 levels were measured in H1 (10 µg/mL) in vitro–stimulated spleen cell–culture supernatant after 72 hours. Concentrations of (A) IFNγ, (B) TNFα, (C) IL4, and (D) IL10 were examined by ELISA. Concentration values expressed as means ± SE of three mice for each group of mice.
Abbreviation: NPs, nanoparticles.
