Abstract

Virus-specific T cells are critical in mediating the pathogenesis of hepatitis B virus (HBV) infection. Interferon gamma (IFNγ)-producing T cells are associated with resolution; in contrast, interleukin-17 (IL-17)-producing T cells are linked to exacerbation of liver inflammation and injury. Checkpoint receptors stringently regulate T cell functions, with their expression profiles varying on different T cell subsets. Blockade of checkpoint receptors may be an effective therapeutic strategy for chronic hepatitis B (CHB); however, blockade may also inadvertently exacerbate proinflammatory responses. In this study, we sought to determine the balance of inflammatory and antiviral T cells and determine their inhibitory receptor profile. The frequency of total and HBV antigen-specific Th17 and Tc17 cells was higher in CHB patients compared with healthy controls (HCs). Th17 and Tc17 cells in CHB patients had significantly lower expression of T cell immunoglobulin and mucin domain protein-3 (TIM-3) compared with HCs, with no difference in programmed death-1 (PD-1) or CD244 expression. Conversely, Th1 and Tc1 cells in CHB patients hyperexpressed PD-1 and CD244, while TIM-3 expression was comparable in both cohorts. During CHB, antiviral IFNγ T cells hyperexpress multiple immune inhibitory receptors driving their functional impairment. In contrast, inflammatory Th17/Tc17 cells hypoexpress TIM-3, but not PD-1 or CD244. Checkpoint inhibitors for CHB should target PD-1 or CD244 to allow restoration of IFNγ responses without affecting inflammatory IL-17 production.

抽象

病毒特异性T细胞在介导乙型肝炎病毒(HBV)感染的发病机制中至关重要。产生干扰素γ(IFNγ)的T细胞与分辨率相关;相反,产生白细胞介素-17(IL-17)的T细胞与肝脏炎症和损伤的恶化有关。检查点受体严格调节T细胞功能,其表达谱在不同的T细胞亚群上变化。阻断检查点受体可能是慢性乙型肝炎(CHB)的有效治疗策略;然而,阻断也可能无意中加剧促炎反应。在这项研究中,我们试图确定炎症和抗病毒T细胞的平衡,并确定其抑制性受体谱。与健康对照(HC)相比,CHB患者中总HBV抗原特异性Th17和Tc17细胞的频率更高。与HC相比,CHB患者中的Th17和Tc17细胞具有显着更低的T细胞免疫球蛋白和粘蛋白结构域蛋白-3(TIM-3)的表达,程序性死亡-1(PD-1)或CD244表达没有差异。相反,CHB患者中的Th1和Tc1细胞过度表达PD-1和CD244,而两组中TIM-3表达相当。在CHB期间,抗病毒IFNγT细胞过度表达多种免疫抑制受体,导致其功能受损。相反,炎性Th17 / Tc17细胞低表达TIM-3,但不表达PD-1或CD244。用于CHB的检查点抑制剂应靶向PD-1或CD244以允许恢复IFNγ应答而不影响炎性IL-17产生。
