NS1: a promising novel target antigen with strong immunogenicity and protective efficacy for avian flavivirus vaccine development.

ABSTRACT: Tembusu virus (TMUV), an avian pathogenic flavivirus, has emerged as a significant threat to the duck industry in Southeast Asia, causing substantial economic losses. Due to the antibody-dependent enhancement (ADE) effect of TMUV subneutralizing antibodies, there is a pressing need to further develop new TMUV vaccine target antigens that ensure both safety and efficacy. Here, the TMUV non-structural protein 1 (NS1) as a target for development of effective anti-TMUV vaccines was unveiled. The amino acid sequences of TMUV NS1 exhibit a high degree of conservation across different strains (92.63-100%). To investigate the potential of TMUV NS1 as a vaccine target, the TMUV NS1-based plasmids were constructed and identified the C-terminal 30 amino acids residues of TMUV E (E_C30) as a
