The present invention relates to a trypanosomal vaccine comprising an FLA1 binding protein, as well as to pharmaceutical compositions comprising said vaccine and their uses in vaccination to prevent or treat trypanosomal infection in a mammal. Thus, also provided are a method of preventing or treating trypanosomal infection comprising administering said vaccine and a kit of parts comprising a medical instrument or other means for administering.

A vaccine composition against infection by Trypanosoma cruzi comprising at least one Trypanosoma cruzi trans-sialidase mutant protein (SEQ 1) and, as adjuvant, a mixture of a highly purified mineral oil and mannide monooleate.

Provided herein are compositions and methods for the prevention and treatment of Chagas disease and acute and chronic symptoms thereof. The compositions comprise recombinant proteins based on an amino terminal fragment of the TSA-1 protein from Trypanosoma cruzi. In the fragment, one or more Cys residues is mutated to prevent the formation of disulfide bonds and to enhance solubility. The recombinant proteins also include a carboxyl terminal fragment of the TSA-1 protein from Trypanosoma cruzi to provide additional stability and solubility. The resulting recombinant protein remains soluble upon prolonged storage at low temperatures and elicits a robust immune response upon administration, including decreasing the number of inflammatory cells in heart tissue of subjects.

Use of synthetic peptides derived from Trypanosoma cruzi antigens and their use in vaccination against trypomastigote infection and Chagas disease. T. cruzi uses several surface proteins to invade the host. In their role of protection, the surface protients ensure the targeting and invasion of specific cells or tissues. A conserved region in the family of mucin-associated surface proteins (MASP) was used to analyze the expression of MASP at different points of invasion and proved to be important for host cell invasion, thus suggesting MASP as a candidate for vaccine development. A synthetic peptide, MASPsyn, was studied and showed efficacy in stimulating antibody and cytokine production necessary for resistance against the parasite.
