PMID: 34078875
Cell Death Discov. 2021 Jun 02;7(1):130. doi: 10.1038/s41420-021-00515-y.

Chronic hepatitis B virus (HBV) infections remain a health burden affecting ~250 million people worldwide. Thus far, available interferon-alpha (IFNα)-based therapies have shown unsatisfactory cure rates, and alternative therapeutic molecules are still required. However, their development has been hampered...
