Abstract

Herpes simplex virus-1 (HSV-1) encephalitis (HSE) is the most common form of sporadic viral encephalitis in western countries. Its pathogenesis remains unclear, as it affects otherwise healthy patients and only a small minority of HSV-1-infected individuals. Here, we elucidate a genetic etiology for HSE in two children with autosomal recessive deficiency in the intracellular protein UNC-93B, resulting in impaired cellular interferon-alpha/beta and -lambda antiviral responses. HSE can result from a single-gene immunodeficiency that does not compromise immunity to most pathogens, unlike most known primary immunodeficiencies. Other severe infectious diseases may also reflect monogenic disorders of immunity.

摘要

单纯疱疹病毒1型（HSV-1）脑炎（HSE）是西方国家散发性病毒性脑炎最常见的形式。其发病机制尚不清楚，因为它影响的是原本健康的患者，且仅在少数HSV-1感染者中出现。在此，我们阐明了两名患有常染色体隐性细胞内蛋白UNC-93B缺陷的儿童患HSE的遗传病因，该缺陷导致细胞α/β干扰素和λ干扰素抗病毒反应受损。与大多数已知的原发性免疫缺陷不同，HSE可能由一种单基因免疫缺陷引起，这种缺陷不会损害对大多数病原体的免疫力。其他严重传染病也可能反映免疫单基因疾病。
