ADCC-Mediated CD56 DIM NK Cell Responses Are Associated with Early HBsAg Clearance in Acute HBV Infection.

The cytolytic CD56 NK-cell subset is selectively activated in acute HBV infection and displays distinct phenotypic and functional profiles associated with efficient and early control of HBV, implicating antibody-mediated cytolytic NK-cell responses in the early control and functional cure of HBV infection.
