英文摘要Sars-like coronavirus (sl-cov) in bats have a similar genomic organization to the human sars-cov. their cognate gene products are highly conserved with the exception of the n-terminal region of the s proteins, which have only 63-64% sequence identity. the n-terminal region of coronavirus s protein is responsible for virus-receptor interaction. in this study, the immunogenicity of the sl-cov s protein (s(sl)) was studied and compared with that of sars-cov (s(sars)). dna immunization in mice with s(sl) elicited a high titer of antibodies against hiv-pseudotyped s(sl). the sera had low cross-reactivity, but no neutralization activity, for the hiv-pseudotyped s(sars). studies using wild bat sera revealed that it is highly likely that the immunodominant epitopes overlap with the major neutralizing sites of the sl-cov s protein. these results demonstrated that sl-cov and sars-cov shared only a limited number of immunogenic epitopes in their s proteins and the major neutralization epitopes are substantially different. this work provides useful information for future development of differential serologic diagnosis and vaccines for coronaviruses with different s protein sequences.
