Brief Summary:
The immune mechanism of the nucleostide analogs NAs in inhibiting HBV replication effectively while having a low sustained virus control rate after drug withdrawal is unclear B cell immunity and antibody response are the keys to prevent HBV reinfection and keep the virus under control T-bet B which can be regulated by IL-21 is a newly discovered major effector B cell in protection of pathogens and it is a main subtype of HBsAg-specific B cells Thus we suspect that T-bet B may play a role in ongoing controlling of the virus after withdraw of NAs in CHB patient Based on our previous studies on CHB immunity we use the RNAseq analyse flow cytometry and Elispot assay to analyze the frequency function and phenotype of B cells in CHB patients with different profiles after withdraw of NAs
