Epstein-Barr virus (EBV) infects ≈ 95% of the adult population. The factors that confer protection in the remaining ≈ 5% remain unknown. In an exploratory study, we assessed immunogenetic factors and tonsillectomy in a cohort of 17 EBV-negative and 39 EBV-positive healthy individuals aged >60 years. Analyses of HLA genotypes revealed an association between EBV negativity and the presence of HLA-C-35T/T and/or HLA-Bw4 alleles. In addition, EBV-negative donors presented with a history of tonsillectomy more often than EBV-positive donors.
EB 病毒(EBV)感染了约 95%的成年人。而其余约 5%的人具有保护作用的因素仍不清楚。在一项探索性研究中,我们评估了 17 名 EBV 阴性和 39 名 EBV 阳性的年龄>60 岁的健康个体的免疫遗传因素和扁桃体切除术。HLA 基因型分析显示,HLA-C-35T/T 和/或 HLA-Bw4 等位基因的存在与 EBV 阴性有关。此外,EBV 阴性供体比 EBV 阳性供体更常接受过扁桃体切除术。
