Abstract

γδ T cells are a unique population of lymphocytes that have regulatory roles in patients with chronic hepatitis B (CHB); however, their role in acute hepatitis B (AHB) infection remains unclear. Phenotype and function of γδ T cells were analyzed in 29 AHB patients, 28 CHB patients, and 30 healthy controls (HCs) using immunofunctional assays. Compared with HCs and CHB patients, decreased peripheral and increased hepatic γδ T cells were found in AHB patients. Increased hepatic γδ T cells in AHB patients were attributed to elevated hepatic chemokine levels. Peripheral γδ T cells exhibited highly activated and terminally differentiated memory phenotype in AHB patients. Consistently, peripheral γδ T cells in AHB patients showed increased cytotoxic capacity and enhanced antiviral activity which was further proved in longitudinal study. Activated γδ T cells in AHB patients exhibited increased cytotoxicity and capacity for viral clearance associated with liver injury and the control of infection.

抽象

γδT细胞是一种独特的淋巴细胞群,在慢性乙型肝炎(CHB)患者中具有调节作用;然而,它们在急性乙型肝炎(AHB)感染中的作用仍不清楚。使用免疫功能测定法在29名AHB患者,28名CHB患者和30名健康对照(HC)中分析γδT细胞的表型和功能。与HCs和CHB患者相比,在AHB患者中发现外周和肝脏γδT细胞减少。 AHB患者肝脏γδT细胞增加归因于肝脏趋化因子水平升高。外周γδT细胞在AHB患者中表现出高度活化和终末分化的记忆表型。一致地,AHB患者的外周γδT细胞显示出增加的细胞毒性能力和增强的抗病毒活性,这在纵向研究中得到进一步证实。 AHB患者中活化的γδT细胞表现出增加的细胞毒性和与肝损伤相关的病毒清除能力和感染控制。
