Disclosed are synthetic nanocarrier methods, and related compositions, comprising administering immunosuppressants and MHC Class I-restricted and/or MHC Class II-restricted epitopes that can generate tolerogenic immune responses (e.g., antigen-specific T effector cell deletion).

The present invention relates to the field of the veterinary medicine of bovine animals. In particular the invention relates to a recombinant Trypanosoma theileri parasite, preferably comprising a heterologous nucleic acid sequence that is capable of encoding a protein for instance an antigen, a cytokine, a hormone, an antimicrobial protein, or an antibody. Also disclosed are uses of and methods for making and using the recombinant T. theileri parasite in medical or non-curative treatments; in particular as a sustained delivery vector for proteins to bovine animals, e.g. as a vaccine.

The present invention relates to a recombinant chimeric protein containing immunogenic regions from the trans-sialidase (TS) protein and amastigote surface protein-2 (ASP-2) from Trypanosoma cruzi and a composition containing said protein that displayed vaccine potential in a murine model. The invention also comprises the use of the chimeric protein for manufacturing vaccines.

The invention relates to a trypanosomalvaccine, to pharmaceutical compositions comprising said vaccine and to their uses in vaccination to prevent trypanosomal infection in a mammal.

A monocomponent vaccine effective to moderate the clinical consequences of Chages disease, capable of stimulating an immune response against the trans-sialidase virulence factor of the Trypanosoma cruzi parasite. The vaccine active ingredient is an immunogenic component with a polynucleotide encoding one or more polypeptide(s) which includes a C-terminal region composed of at least two repetitive units of amino acids, with a polypeptide with trans-sialidase activity of Trypanosoma cruzi fused to the C-terminal region. The vaccine further comprises an aluminum oxide adjuvant that does not inhibit trans-sialidase enzymatic activity of the immunogen portion.
