35 Taken together, it is well defined that high antigen concentrations and persistent stimulation of HBV can promote HBV-specific T-cell exhaustion by affecting the phenotype and function of peripheral and intrahepatic T cells through the PD-1/PD-L1 pathway, but the exact mechanism remains to be elucidated as the partial recovery of some HBV CD8 + specificities in a proportion of patients with CHB by blocking PD-1 pathway apparently shows that there exists other mechanisms other than PD-1/PD-L1 that may contribute to T-cell exhaustion
