Human leukocyte antigen (HLA) plays an important role in immune responses to infections, especially in the development of acquired immunity. Given the high degree of polymorphisms that HLA molecules present, some will be more or less effective in controlling SARS-CoV-2 infection. We wanted to analyze whether certain polymorphisms may be involved in the protection or susceptibility to COVID-19.
We studied the polymorphisms in HLA class I (HLA-A, -B and -C) and II (HLA-DRB1 and HLA-DQB1) molecules in 450 patients who required hospitalization for COVID-19, creating one of the largest HLA-typed patient cohort to date.
Our results show that there is no relationship between HLA polymorphisms or haplotypes and susceptibility or protection to COVID-19.
Our results may contribute to resolve the contradictory data on the role of HLA polymorphisms in COVID-19 infection.
人类白细胞抗原(HLA)在免疫应对感染方面发挥着重要作用,尤其是在获得性免疫的发展方面。鉴于 HLA 分子具有高度多态性,某些分子在控制 SARS-CoV-2 感染方面可能或多或少地有效。我们希望分析某些多态性是否可能与 COVID-19 的保护或易感性有关。
我们研究了 450 名因 COVID-19 而需要住院的患者中 HLA Ⅰ类(HLA-A、-B 和 -C)和 II 类(HLA-DRB1 和 HLA-DQB1)分子的多态性,创建了迄今为止最大的 HLA 分型患者队列之一。
我们的结果表明,HLA 多态性或单倍型与 COVID-19 的易感性或保护之间没有关系。
我们的结果可能有助于解决 HLA 多态性在 COVID-19 感染中的作用的矛盾数据。
