Abstract
Severe acute respiratory syndrome (SARS) is a life-threatening disease caused by a newly identified coronavirus (CoV), SARS-CoV. The spike (S) glycoprotein of CoV is the major structural protein responsible for induction of host immune response and virus neutralization by antibodies. Hence, knowledge of neutralization determinants on the S protein is helpful for designing protective vaccines. To analyze the antigenic structure of the SARS-CoV S2 domain, the carboxyl-terminal half of the S protein, we first used sera from convalescent SARS patients to test the antigenicity of 12 overlapping fragments spanning the entire S2 and identified two antigenic determinants (Leu 803 to Ala 828 and Pro 1061 to Ser 1093). To determine whether neutralizing antibodies can be elicited by these two determinants, we immunized animals and found that both of them could induce the S2-specific antisera. In some animals, however, only one determinant (Leu 803 to Ala 828) was able to induce the antisera with the binding ability to the native S protein and the neutralizing activity to the SARS-CoV pseudovirus. This determinant is highly conserved across different SARS-CoV isolates. Identification of a conserved antigenic determinant on the S2 domain of the SARS-CoV S protein, which has the potential for inducing neutralizing antibodies, has implications in the development of effective vaccines against SARS-CoV.

type="abstract" xml:lang="en"><p>Severe acute respiratory syndrome (SARS) is a life-threatening disease caused by a newly identified coronavirus (CoV), SARS-CoV. The spike (S) glycoprotein of CoV is the major structural protein responsible for induction of host immune response and virus neutralization by antibodies. Hence, knowledge of neutralization determinants on the S protein is helpful for designing protective vaccines. To analyze the antigenic structure of the SARS-CoV S2 domain, the carboxyl-terminal half of the S protein, we first used sera from convalescent SARS patients to test the antigenicity of 12 overlapping fragments spanning the entire S2 and identified two antigenic determinants (Leu 803 to Ala 828 and Pro 1061 to Ser 1093). To determine whether neutralizing antibodies can be elicited by these two determinants, we immunized animals and found that both of them could induce the S2-specific antisera. In some animals, however, only one determinant (Leu 803 to Ala 828) was able to induce the antisera with the binding ability to the native S protein and the neutralizing activity to the SARS-CoV pseudovirus. This determinant is highly conserved across different SARS-CoV isolates. Identification of a conserved antigenic determinant on the S2 domain of the SARS-CoV S protein, which has the potential for inducing neutralizing antibodies, has implications in the development of effective vaccines against SARS-CoV.</p></div></front></TEI><affiliations><list><country><li>République populaire de Chine</li></country><region><li>Pékin</li></region><settlement><li>Pékin</li></settlement><orgName><li>Université de Pékin</li></orgName></list><tree><country name="République populaire de Chine"><noRegion><name sortKey="Zhang, Hong" sort="Zhang, Hong" uniqKey="Zhang H" first="Hong" last="Zhang">Hong Zhang</name></noRegion><name sortKey="Deng, Hongkui" sort="Deng, Hongkui" uniqKey="Deng H" first="Hongkui" last="Deng">Hongkui Deng</name><name sortKey="Ding, Mingxiao" sort="Ding, Mingxiao" uniqKey="Ding M" first="Mingxiao" last="Ding">Mingxiao Ding</name><name sortKey="Li, Jian" sort="Li, Jian" uniqKey="Li J" first="Jian" last="Li">Jian Li</name><name sortKey="Lian, Gewei" sort="Lian, Gewei" uniqKey="Lian G" first="Gewei" last="Lian">Gewei Lian</name><name sortKey="Nie, Yuchun" sort="Nie, Yuchun" uniqKey="Nie Y" first="Yuchun" last="Nie">Yuchun Nie</name><name sortKey="Qu, Xiuxia" sort="Qu, Xiuxia" uniqKey="Qu X" first="Xiuxia" last="Qu">Xiuxia Qu</name><name sortKey="Shi, Xuanling" sort="Shi, Xuanling" uniqKey="Shi X" first="Xuanling" last="Shi">Xuanling Shi</name><name sortKey="Wang, Guangwen" sort="Wang, Guangwen" uniqKey="Wang G" first="Guangwen" last="Wang">Guangwen Wang</name><name sortKey="Wang, Wei" sort="Wang, Wei" uniqKey="Wang W" first="Wei" last="Wang">Wei Wang</name><name sortKey="Yin, Xiaolei" sort="Yin, Xiaolei" uniqKey="Yin X" first="Xiaolei" last="Yin">Xiaolei Yin</name><name sortKey="Zhao, Yang" sort="Zhao, Yang" uniqKey="Zhao Y" first="Yang" last="Zhao">Yang Zhao</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
