In this study, we evaluated the potential of a novel synthetic adjuvant designated IC31 for the ability to augment the immune response and protective efficacy of the well-known mycobacterial vaccine antigen, Ag85B-ESAT-6. The IC31 adjuvant, consisting of a vehicle based on the cationic peptide KLKL5KLK and the immunostimulatory oligodeoxynucleotide ODN1a signalling through the TLR9 receptor, was found to promote highly efficient Th1 responses. The combination of Ag85B-ESAT-6 and IC31 exhibited significant levels of protection in the mouse aerosol challenge model of tuberculosis and a detailed analysis of the immune response generated revealed the induction of CD4 T cells giving rise to high levels of IFN-γ secretion. Furthermore, the combination of Ag85B-ESAT-6/IC31 was found to confer efficient protection in the guinea pig aerosol model of tuberculosis infection and is at present moving towards clinical testing.
