Neisseria meningitidis type B is a major world-health problem. The Meningococcus type B capsular polysaccharide (MnB) is very poorly immunogenic and no vaccine to the antigen exists. Here, we conjugated the MnB to a T-cell carrier peptide (p458) derived from the self-60kDa heat shock protein molecule. The conjugate vaccine was effective in inducing(More)
EhCPADH is an immunogenic, heterodimeric protein that is formed by EhCP112 (cysteine protease) and EhADH112 (adhesin), polypeptides involved in Entamoeba histolytica's cytopathic effect, target-cell adherence and phagocytosis. The EhCPADH complex is located in the plasma membrane and cytoplasmic vacuoles. Here, the independent expression of EhCP112 and(More)
Proteoliposomes purified from the Outer Membrane of Neisseria meningitidis B, have been successfully used as core for adjuvants and vaccine formulations. We have tried to increase their structural definition and to conserve their efficacy and stability avoiding the addition of the aluminum hydroxide to the final formulation. Liposomal particle systems were(More)
