IMMUNOGENIC COMPOSITIONS COMPRISING HMGB1 POLYPEPTIDES

摘要

The present invention relates to novel immunogenic compositions (e.g., vaccines), the production of such immunogenic compositions and methods of using such compositions. More specially, this invention provides unique immunogenic molecules comprising an HMGB1 polypeptide (e.g., an HMGB1 B-box polypeptide) and an antigen. Even more specificially, this invention provides novel fusion proteins comprising an isolated HMGB1 polypeptide and an antigen such that administration of these fusion proteins provides the two signals required for native T - cell activation.
