摘要： The present disclosure provides polypeptides derived from SARS-CoV-2 which have therapeutic use. One such polypeptide is a polypeptide, referred to as “Npep2,” is derived from the SARS-CoV-2 protein N and has at least 50 consecutive amino acids of the amino acid sequence having at least 90% identity with the amino acid sequence that ranges from the residue at position 276 to the residue at position 411 of SEQ ID NO:2. Further described are conjugates wherein a heterologous polypeptide is conjugated or fused to Npep2. The present disclosure further provides vaccines employing the polypeptides, polynucleotides encoding the polypeptides, and methods of vaccinating subjects against SARS-CoV-2 by administering a therapeutically effective amount of one or more of the polypeptides.

摘要： 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.

摘要： 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.
