Fusion proteins for use as immunogenic enhancers for inducing antigen-specific T cell responses |
摘要 |
A vaccine composition comprising a fusion protein for inducing enhanced pathogen antigen-specific T cell responses is disclosed. The fusion protein comprises: (a) an antigen-presenting cell (APC)-binding domain or a CD91 receptor-binding domain, located at the N-terminus of the fusion protein; (b) a translocation peptide of 34-112 amino acid residues in length, comprising an amino acid sequence that is at least 90% identical to SEQ ID NO: 4, 2, 3, or 6, located at the C-terminus of the APC-binding domain or the CD91 receptor-binding domain; and (c) an antigen of a pathogen, located at the C-terminus of the translocation peptide; (d) a nuclear export signal, comprising the amino acid sequence of SEQ ID NO: 13; and (e) an endoplasmic reticulum retention sequence, located at the C-terminus of the fusion protein. |

1. A fusion protein comprising;
(a) an antigen-presenting cell (APC)-binding domain or a CD91 receptor-binding domain, located at the N-terminus of the fusion protein; (b) a translocation peptide of 34-112 amino acid residues in length, comprising an amino acid sequence that is at least 90% identical to SEQ ID NO: 4, 2, or 3, located at the C-terminus of the APC-binding domain or the CD91 receptor-binding domain; and (c) an antigen of a pathogen; (d) a nuclear export signal, comprising the amino acid sequence of SEQ ID NO: 13, wherein the C-terminal amino acid of the SEQ ID NO: 13 is alanine; and (e) an endoplasmic reticulum retention sequence, located at the C-terminus of the fusion protein; wherein the nuclear export signal is located between the antigen and the endoplasmic reticulum retention sequence, or between the translocation peptide and the antigen. |
