Hepatitis A virus (HAV) usually results in asymptomatic infection or mild disease, but in a small subset of patients it can lead to severe disease and even liver failure. In this issue of the JCI, Kim et al. identify a polymorphism associated with this increased disease risk in the gene that encodes the HAV receptor--TIM1. Importantly, this TIM1 gene polymorphism protects from the development of atopic diseases in HAV-seropositive individuals.
甲型肝炎病毒(HAV)通常导致无症状感染或轻度疾病,但在一小部分患者中,它可导致严重疾病甚至肝衰竭。在本期 JCI 中,Kim 等人鉴定出编码 HAV 受体--TIM1 的基因中与这种疾病风险增加相关的一种多态性。重要的是,这种 TIM1 基因多态性可预防 HAV 血清阳性个体发生特应性疾病。
