The relative resistance of liver cells in primary monolayer cell culture to the cytocidal effects of methotrexate, Adriamycin, cycloheximide, or aflatoxin B1 was studied using cells derived from normal rats, rats subjected to two-thirds hepatectomy, or rat fed dietary carcinogen. Normal rat liver cells were highly sensitive to the toxic effects of methotrexate. Adriamycin, cycloheximide, and aflatoxin B1. In contrast, liver cells from carcinogen-treated rats were resistant to the toxic effects of these agents. Cells derived from rats at 24 hr post two-thirds hepatectomy were sensitive to Adriamycin but not to cycloheximide or aflatoxin B1.

Hepatitis B virus (HBV) can cause chronic infections, significantly increasing the risk of death from cirrhosis and hepatocellular carcinoma (HCC). A key player in chronic HBV infection is covalently closed circular DNA (cccDNA), a stable episomal form of viral DNA that acts as a persistent reservoir in infected hepatocytes and drives continuous viral replication. Despite the development of several animal models, few adequately replicate cccDNA formation and maintenance, limiting our understanding of its dynamics and the evaluation of potential therapeutic interventions targeting cccDNA.

The study of hepatitis C virus (HCV) replication in cell culture is mainly based on cloned viral isolates requiring adaptation for efficient replication in Huh7 hepatoma cells. The analysis of wild-type (WT) isolates was enabled by the expression of SEC14L2 and by inhibitors targeting deleterious host factors. Here, we aimed to optimize cell culture models to allow infection with HCV from patient sera.

SARS-CoV-2 infection induces a humoral immune response, producing virus-specific antibodies such as IgM, IgG, and IgA. IgA antibodies are present at mucosal sites, protecting against respiratory and other mucosal infections, including SARS-CoV-2, by neutralizing viruses or impeding attachment to epithelial cells. Since SARS-CoV-2 spreads through the nasopharynx, the specific IgAs of SARS-CoV-2 are produced quickly after infection, effectively contributing to virus neutralization.

The hepatitis B virus (HBV) infects approximately 290 million people globally, with chronic infection sustained by persistent viral gene expression. Recent single-cell analyses of HBV viral transcripts have uncovered novel features of HBV transcription and provided fresh insights into its regulation at the single-cell level. In this review, we summarize the latest advancements in understanding HBV viral transcription in individual hepatocytes and highlight emerging technologies that hold promise for future research.
