Persistent hepatitis B virus (HBV) infection is characterized by a weak CD8(+) T cell response to HBV. Immunotherapeutic strategies that overcome tolerance and boost these suboptimal responses may facilitate viral clearance in chronically infected individuals. Therefore, we examined whether CD25(+)CD4(+) regulatory T (Treg) cells might be involved in a inhibition of CD8(+) T cell priming or in the modulation of the magnitude of the 'peak' antiviral CD8(+) T cell response primed by DNA immunization.
