Silencing HBV transcription with SMC5/6: has a path been found?
Chronic hepatitis B virus (HBV) infection is maintained by the viral nuclear covalently closed circular DNA (cccDNA) that is the transcriptional template for HBV’s mRNAs. The cccDNA is durable during current therapies, but a functional cure for HBV infections will require stable, off-treatment silencing of any cccDNA remaining in the body after treatment cessation.1 The cccDNA is silenced naturally during infection by binding of the structural maintenance of chromosome 5/6 (SMC5/6) complex to the cccDNA, and HBV antagonises this silencing with the HBx protein that binds to SMC5/6 and triggers its proteasomal degradat...

Therapeutic shutdown of HBV transcripts promotes reappearance of the SMC5/6 complex and silencing of the viral genome in vivo
Conclusion
These results reveal that therapeutics abrogating all HBV transcripts including HBx promote epigenetic suppression of the HBV minichromosome, whereas strategies protecting the human hepatocytes from reinfection are needed to maintain cccDNA silencing.

Blocking neddylation elicits antiviral effect against hepatitis B virus replication
CONCLUSION: The manipulation of the neddylation pathway can thus provide new tools interfering with HBV persistence as well as novel therapeutic strategies against chronic hepatitis B.PMID:34716866 | DOI:10.1007/s11033-021-06886-w
