Abstract
A composition/vaccine to intensify and expand the magnitude of the host immune response against the Ag 85 and ESAT6 proteins thereby blocking the inhibitory effect of these two classes of secreted proteins, and thus promoting the clearing or control of the MTb infection. Fusion proteins are created between immunogenic fragments of the soluble secreted MTb proteins Ag 85 and ESAT6 (which are inhibitors of the immune response) and the extracellular domain (ecd) of the immunostimulatory protein ecdCD40 ligand (ecdCD40L). Fusion proteins are created using both Ag85 and ESAT-6 immunogenic peptides and ecdCD40L, to induce a more potent immune response against the MTb than would the use of either protein (Ag85 or ESAT-6) alone. Both a humoral and cellular immune response are induced. The composition/vaccine further avoids the requirement for use of attenuated strains of the tubercle bacillis, to induce an immune response to the Ag85 and ESAT6 proteins.
