IL17A and infection: We show that vaccination with either ESAT61-20 or TriFu64 induces TNFα and IL-17 antigen-specific responses with a tendency to high TNFα in the TriFu64 and high IL-17 in the ESAT61-20. Upon infection, there is a very clear polarization in the TriFu64 vaccinated mice with a three-fold higher level of TNFα transcription than IL-17, while ESAT61-20 vaccinated mice have equivalent transcriptional levels for these cytokines.
