SARS-CoV-2 infection is causing a pandemic disease that is reflected in challenging public health problems worldwide. Human leukocyte antigen (HLA)-based epitope prediction and its association with disease outcomes provide an important base for treatment design. A bioinformatic prediction of T cell epitopes and their restricted HLA Class I and II alleles was performed to obtain immunogenic epitopes and HLA alleles from the spike protein of the severe acute respiratory syndrome coronavirus 2 virus. Also, a correlation with the predicted fatality rate of hospitalized patients in 28 states of Mexico was done. Here, we describe a set of 10 highly immunogenic epitopes, together with different HLA alleles that can efficiently present these epitopes to T cells. Most of these epitopes are located within the S1 subunit of the spike protein, suggesting that this area is highly immunogenic. A statistical negative correlation was found between the frequency of HLA-DRB1*01 and the fatality rate in hospitalized patients in Mexico.
SARS-CoV-2 感染正在引发一种大流行疾病,这在全球范围内反映出具有挑战性的公共卫生问题。基于人类白细胞抗原(HLA)的表位预测及其与疾病结果的关联为治疗设计提供了重要基础。对 T 细胞表位及其受限的 HLA Ⅰ类和Ⅱ类等位基因进行生物信息学预测,以从严重急性呼吸综合征冠状病毒 2 病毒的刺突蛋白中获得免疫原性表位和 HLA 等位基因。还与墨西哥 28 个州住院患者的预测病死率进行了相关性分析。在这里,我们描述了一组 10 个高免疫原性表位,以及能够有效将这些表位呈递给 T 细胞的不同 HLA 等位基因。这些表位大多数位于刺突蛋白的 S1 亚单位内,表明该区域具有高度的免疫原性。在墨西哥住院患者中,HLA-DRB1*01 的频率与病死率之间存在统计学上的负相关。
