MIG and the Regulatory Cytokines IL-10 and TGF-β1 Correlate with Malaria Vaccine Immunogenicity and Efficacy
Figure 2
The Expression of Cytokines in Unstimulated Cells Before and After Vaccination.
Expression of IFN-γ, MIG, TGF-β1, FoxP3 and IL-10 was measured by real-time RT-PCR in total PBMCs following 12 hour culture in media only in subjects who received vaccination with RTS,S/AS02A and MVA-CS. Results are expressed as copy number relative to the housekeeping gene HPRT. Median values (6–12 subjects) are shown. Vac+7 = seven days after the final vaccination, Vac+28 = 28 days after the final vaccination, each subject received two doses of RTS,S/AS02A and one dose of MVA-CS. A) IFN-g mRNA, B) MIG mRNA, C) TGF-β1 mRNA, D) FoxP3 mRNA, E) IL-10 mRNA and F) Correlation of MIG mRNA expression at day 7 with days to parasitemia following sporozoite challenge.
