Chronic hepatitis E virus (HEV) infection, which primarily affects the immunocompromised, can rapidly progress to liver fibrosis and cirrhosis if untreated. However, current therapeutic options are extremely limited and have significant adverse effects. Over the past decade, virus-specific T-cell therapy has shown promise as an alternative safe and effective treatment strategy for other refractory viral infections such as cytomegalovirus, adenovirus, and polyomavirus infections in hematopoietic stem cell and solid organ transplant recipients. Given the key role of T lymphocytes in the control of HEV replication and the fact that HEV-specific T-cell responses are typically diminished in immunosuppressed patients with persistent HEV infection, adoptive immunotherapy with HEV-specific T cells could serve as a novel addition to the HEV treatment repertoire, which is in dire need of expansion.
慢性戊型肝炎病毒(HEV)感染主要影响免疫功能低下者,若不治疗,可迅速发展为肝纤维化和肝硬化。然而,目前的治疗选择极其有限,且有显著的不良反应。在过去十年中,病毒特异性T细胞疗法已显示出有望成为一种替代的安全有效的治疗策略,用于治疗其他难治性病毒感染,如造血干细胞和实体器官移植受者中的巨细胞病毒、腺病毒和多瘤病毒感染。鉴于T淋巴细胞在控制HEV复制中的关键作用,以及在持续性HEV感染的免疫抑制患者中HEV特异性T细胞反应通常减弱这一事实,采用HEV特异性T细胞进行过继性免疫治疗可作为急需扩充的HEV治疗方法中的一种新补充。
