Hepatitis B virus RNA (HBV RNA) (HBV RNA)

Hepatitis B virus (HBV) RNA consists of several distinct transcripts, including the pregenomic RNA (pgRNA) and various subgenomic mRNAs, which are transcribed from the covalently closed circular DNA (cccDNA) in the nucleus of infected hepatocytes (Source: NIH, PubMed). The pgRNA serves as the essential template for reverse transcription into new viral DNA and also encodes the core and polymerase proteins, while subgenomic RNAs encode the surface antigens (HBsAg) and X protein (Source: Journal of Hepatology). These RNAs are critical for maintaining the viral lifecycle and contributing to the high levels of viral proteins that suppress the host immune response. Therapeutic strategies targeting HBV RNA, such as antisense oligonucleotides (ASOs) and small interfering RNAs (siRNAs), are designed to bind and trigger the degradation of these transcripts (Source: GSK, Vir Biotechnology). By reducing the expression of all HBV proteins, including HBsAg, these therapies aim to restore the host's immune control over the virus, potentially leading to a functional cure for chronic hepatitis B (Source: Lancet Gastroenterology & Hepatology). Furthermore, serum HBV RNA has emerged as a significant biomarker for monitoring the activity of intrahepatic cccDNA and predicting treatment response in patients undergoing antiviral therapy (Source: Hepatology International).
