Pharmaceutical or food composition for treating pathologies associated with graft rejection or an allergic or autoimmune reaction

摘要

The present invention is related to a process for obtaining a composition comprising peptides bound to one or more heat shock protein(s) and for possibly recovering from said composition the bound peptides, wherein the peptides resulting from a previously in-vitro hydrolysis of at least one immunogenic and antigenic macromolecular structure, are mixed in-vitro with one or more heat shock protein(s). The present invention is also related to the compositions obtained by said process.
