Gender-Specific Alteration of Steroid Metabolism and Its Impact on Viral Replication in a Mouse Model of Hepatitis B Virus Infection

This study examined the effects of hepatitis B virus (HBV) infection on steroid metabolism in male and female mice, revealing significant alterations only in males. HBV infection led to increased dehydroepiandrosterone (DHEA) levels and decreased androgen levels, which inhibited viral replication by suppressing HBV promoter activity. The research highlights sex-specific changes in steroid metabolism due to HBV, with dihydrotestosterone (DHT) playing a protective role against the virus. These findings provide insights into the hormonal influences on viral replication and suggest potential implications for understanding gender disparities in HBV infection outcomes.
