['Myeloid and plasmacytoid dendritic cells (mDCs, pDCs) are functionally impaired in patients with chronic hepatitis B (CHB). Adoptive immunotherapy can suppress hepatitis B virus (HBV) replication in CHB patients, but whether it can restore the functionality of mDCs and pDCs remains unknown.', 'Autologous cytokine-induced killer (CIK) cells obtained from 14 CHB patients were transfused back to patients, case by case, to observe the effect of CIK-cell treatment on the frequency and functionality of mDCs and pDCs in CHB patients during a 24-week follow-up investigation.', 'Seven virological responders exhibited a sustained decrease in HBV load after CIK-cell transfusion; another seven non-virological responders showed only sustained high levels of HBV load during the 24-week period following CIK-cell transfusion. The rate of hepatitis B e antigen loss or seroconversion was also higher in virological responders than in non-virological responders. Importantly, we found that the frequency and cytokine-producing capacity of mDCs and pDCs increased significantly in virological responders, but not in non-virological responders. In addition, these patients exhibited a close correlation between restoration DC subsets and a decrease in HBV DNA load, rather than a change in the alanine aminotransferase level.'] Does viral suppression correlate with dendritic cell restoration in chronic hepatitis B patients with autologous cytokine-induced killer cell transfusion?
