Dynamic Changes of Monocytes and NK Cells of CHC Patient Treated by DAAs

15 treatment-naive CHC patients and 10 healthy controls were recruited. Patients were examined before DAAs therapy (0w) and at weeks 4 (4w) and weeks 12 (12w) of the therapy. The percentage of monocytes,NK cells of the peripheral blood were analyzed by flow cytometry. Serum cytokines IL-12, IL-18, CXCL10, CXCL11, sCD14 and sCD163 were measured by enzyme linked immunosorbent assay.
