Imaging of Hepatitis B Virus Nucleic Acids: Current Advances and Challenges.

Hepatitis B virus infections are the main reason for hepatocellular carcinoma development. Current treatment reduces the viral load but rarely leads to virus elimination. Despite its medical importance, little is known about infection dynamics on the cellular level not at least due to technical obstacles.

Impact of ADAR-induced editing of minor viral RNA populations on replication and transmission of SARS-CoV-2.

Adenosine deaminases acting on RNA (ADAR) are RNA-editing enzymes that may restrict viral infection. We have utilized deep sequencing to determine adenosine to guanine (A→G) mutations, signifying ADAR activity, in clinical samples retrieved from 93 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected patients in the early phase of the COVID-19 pandemic. A→G mutations were detected in 0.
