The emergence of resistant hepatitis B virus (HBV), with mutations in the YMDD motif of the polymerase gene after treatment with lamivudine, is becoming an important clinical problem.

Cytomegalovirus. Inactivation or immunoabsorption of HBV from sera resulted in loss of HBV-induced inhibition of hematopoietic stem cells. The activity of the acyclic/carbocyclic guanosine analogues has been determined against a wide spectrum of viruses, including the HSV-1, HSV-2, VZV, HCMV, and also human herpesviruses type 6 (HHV-6), type 7 (HHV-7) and type 8 (HHV-8), and hepatitis B virus (HBV). Using this parallel refinement program, we refine the herpesvirus B-capsid from 355-particle images to 13-A resolution. Therefore, we concluded that the antiviral activity of AT-61 is specific for HBV replication and most likely occurs at one of the steps between the synthesis of viral RNA and the packaging of pregenomic RNA into immature core particles.
Therefore, lifelong therapy is required for the majority of chronically infected persons. Selected References These references are in PubMed. Several herpesviral particles complexed with globular material and spherical structures for 15 to 25 nm in diameter were visualized in the same CSF on EM grids coated with anti-human IgG serum.
