Antiviral Intrahepatic T-Cell Responses Can Be Restored by Blocking Programmed Death-1 Pathway in Chronic Hepatitis B
Open accessAbstract
BACKGROUND & AIMS The antiviral function of peripheral hepatitis B virus (HBV)-specific T cells can be increased in patients with chronic hepatitis B by blocking the interaction of programmed death (PD)-1 with its ligand PD-L1. However, no information is available about the effects of this blockade on intrahepatic lymphocytes. We studied T-cell exhaustion and the effects of PD-1/PD-L1 blockade on intrahepatic and circulating HBV-specific T cells in patients with chronic hepatitis B. METHODS A total of 42 patients with chronic HBV infection who underwent liver biopsy were studied. The ex vivo phenotype of peripheral and intrahepatic HBV-specific CD8(+) T cells was assessed by flow cytometry with class I tetramers and antibodies to T-cell differentiation molecules. Functional recovery was evaluated by analyzing expansion and production of interferon (IFN)-gamma and interleukin (IL)-2 after short-term incubation of T cells with HBV peptides in the presence of anti-PD-L1 or control antibodies. RESULTS Intrahepatic HBV-specific CD8(+) cells expressed higher levels of PD-1 and lower levels of CD127 than their peripheral counterparts. Blockade of PD-1/PD-L1 interaction increased CD8(+) cell proliferation and IFN-gamma and IL-2 production by circulating intrahepatic lymphocytes, even though anti-PD-L1 had a stronger effect on intrahepatic compared with peripheral T cells. CONCLUSIONS T-cell exhaustion by high antigen concentrations promotes HBV-specific T-cell dysfunction by affecting phenotype and function of peripheral and intrahepatic T cells. By restoring antiviral T-cell functions, not only in peripheral but also in intrahepatic lymphocytes, anti-PD-L1 might be a good therapeutic candidate for chronic HBV infection.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
