Vaccine-induced immunity is expected to target the native antigens expressed by the pathogens. Therefore, it is highly important to generate vaccine antigens that are immunologically indistinguishable from the native antigens. Nucleic acid vaccines, comprised of DNA, mRNA, or recombinant viral vector vaccines, introduce the genetic material encoding the antigenic protein for the host to express. Because these proteins will undergo host posttranslational modifications, host glycosylation can potentially alter the structure and immunological efficacy of the antigen. In this review, we discuss the potential impact of host protein glycosylation on the immune responses generated by nucleic acid vaccines against bacterial and viral pathogens.
疫苗诱导的免疫反应预计针对病原体表达的天然抗原。因此，生成在免疫学上与天然抗原无法区分的疫苗抗原非常重要。核酸疫苗包括 DNA、mRNA 或重组病毒载体疫苗，将编码抗原蛋白的遗传物质导入宿主以进行表达。由于这些蛋白将经历宿主翻译后修饰，宿主糖基化可能改变抗原的结构和免疫效力。在这篇综述中，我们讨论了宿主蛋白糖基化对核酸疫苗针对细菌和病毒病原体产生的免疫反应的潜在影响。
