Chlamydiae are intracellular bacterial pathogens responsible for a variety of infections. The inventors produced an antibody that is directed against a surface antigen (i.e., CD40) of an antigen presenting cell (i.e., dendritic cell) wherein the heavy chain and/or light chain is conjugated to the MOMP VS4 domain of Chlamydia trachomatis for its use as vaccine.

Chlamydiae are intracellular bacterial pathogens responsible for a variety of infections. The inventors have set up candidate vaccines against Chlamydia trachomatis. In particular, the inventors have identified specific epitopes to be included in vaccine candidates thanks to in silico analysis of the amino-acid sequence of these proteins to map predicted MHC-I and -II epitopes by online software (NetMHC-4.0 and NetMHCII-2.3) and peptide binding prediction software. B cell epitopes were also mapped using online software (BepiPred-2.0 and Discotope). Finally, the inventors have generated some specific CD40 or Langerin antibodies comprising one or more identified epitope(s) of the present invention and that are suitable for vaccine purposes. Therefore, the present invention relates to Chlamydia trachomatis (Ct) antigenic polypeptides and uses thereof for vaccine purposes.

The present invention provides methods, compositions, systems, and kits comprising nano-satellite complexes and/or serum albumin carrier complexes, which are used for modulating antigen-specific immune response (e.g., enhancing anti-tumor immunity). In certain embodiments, the nano-satellite complexes comprise: a) a core nanoparticle complex comprising a biocompatible coating surrounding a nanoparticle core; b) at least one satellite particle attached to, or absorbed to, the biocompatible coating; and c) an antigenic component conjugated to, or absorbed to, the at least one satellite particle component. In certain embodiments, the complexes further comprise: d) a type I interferon agonist agent. In some embodiments, the serum albumin complexes comprise: a) at least part of a serum albumin protein, b) an antigenic component conjugated to the carrier protein, and c) a type I interferon agonist agent.
