CNDP2 and tuberculosis: Given the demonstrated importance of proteases PepA, PepN, and Msh1 (besides their immunogenic capacity) for the survival and virulence of Mtb, this work investigates the immunogenicity of a recombinant fusion protein composed of immunodominant epitopes from these proteases, development of a recombinant BCG vaccine and their use in different vaccination strategies for the prevention of TB in a murine model.
