Epstein-Barr virus (EBV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are extraordinary in their ability to activate autoimmunity as well as to induce diverse autoimmune diseases. Here we reviewed the current knowledge on their relation. Further, we suggested that molecular mimicry could be a possible common mechanism of autoimmunity induction in the susceptible individuals infected with SARS-CoV-2. Molecular mimicry between SARS-CoV-2 and human proteins, and EBV and human proteins, are present. Besides, relation of the pathogenicity associated with both coronavirus diseases and EBV supports the notion. As a proof-of-the-concept, we investigated 8mer sequences with shared 5mers of SARS-CoV-2, EBV, and human proteins, which were predicted as epitopes binding to the same human leukocyte antigen (HLA) supertype representatives. We identified significant number of human peptide sequences with predicted-affinities to the HLA-A02:01 allele. Rest of the peptide sequences had predicted-affinities to the HLA-A02:01, HLA-B40:01, HLA-B27:05, HLA-A01:01, and HLA-B39:01 alleles. Carriers of these serotypes can be under a higher risk of autoimmune response induction upon getting infected, through molecular mimicry-based mechanisms common to SARS-CoV-2 and EBV infections. We additionally reviewed established associations of the identified proteins with the EBV-related pathogenicity and with the autoimmune diseases.
爱泼斯坦-巴尔病毒(EBV)和严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)在激活自身免疫以及诱导多种自身免疫性疾病方面具有非凡的能力。在这里,我们回顾了它们之间关系的现有知识。此外,我们提出,分子模拟可能是 SARS-CoV-2 感染易感个体诱导自身免疫的一种可能的共同机制。SARS-CoV-2 与人蛋白之间以及 EBV 与人蛋白之间存在分子模拟。此外,与这两种冠状病毒疾病和 EBV 相关的致病性的关系支持这一观点。作为概念验证,我们研究了 SARS-CoV-2、EBV 和人蛋白之间具有共享 5 个氨基酸的 8 个氨基酸序列,这些序列被预测为与相同人类白细胞抗原(HLA)超型代表结合的表位。我们鉴定了大量与 HLA-A02:01 等位基因具有预测亲和力的人类肽序列。其余肽序列与 HLA-A02:01、HLA-B40:01、HLA-B27:05、HLA-A01:01 和 HLA-B39:01 等位基因具有预测亲和力。这些血清型的携带者在感染后可能由于 SARS-CoV-2 和 EBV 感染共有的分子模拟机制而处于更高的自身免疫反应诱导风险之下。我们还回顾了鉴定出的蛋白与 EBV 相关的致病性以及与自身免疫性疾病的已确立关联。
