|June 6, 2015
Summary
Hepatitis B virus (HBV) entry into liver cells is mediated by the sodium taurocholate cotransporting polypeptide (NTCP) receptor. Bile acid derivatives targeting NTCP effectively block HBV and hepatitis D virus (HDV) infections.
Area of Science:
- Hepatology
- Virology
- Molecular Biology
Background:
- Hepatitis B virus (HBV) infection is a significant global health issue.
- Lack of effective cell culture and animal models has hindered HBV research and antiviral development.
- Sodium taurocholate cotransporting polypeptide (NTCP) is a liver-expressed bile acid transporter.
Purpose of the Study:
- To investigate NTCP as a critical receptor for HBV and hepatitis D virus (HDV) entry.
- To explore bile acids and their derivatives as potential antivirals against HBV/HDV.
- To understand the role of NTCP in viral species specificity.
Main Methods:
- Identification of NTCP as the HBV/HDV receptor.
- Characterization of NTCP's role in viral entry and species specificity.
- Evaluation of bile acids and development of bile acid derivatives as inhibitors of viral infection and taurocholate transport.
Main Results:
- NTCP was confirmed as the essential receptor for HBV and HDV entry into liver cells.
- NTCP mediates the species specificity of HBV and HDV infections.
- Bile acid derivatives were developed that inhibit both taurocholate transport and viral infections.
Conclusions:
- NTCP is a key determinant for HBV and HDV infection at the entry level.
- Bile acids and their derivatives show promise as novel antivirals for HBV and HDV.
- Targeting NTCP offers a new therapeutic strategy for HBV infection treatment.

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

01:20Receptor-mediated Endocytosis
12.7K
Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

1.4K
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

01:45Tail-anchoring of Proteins in the ER Membrane
4.1K
Tail-anchored, or TA, proteins are estimated to make up to 3-5% of membrane proteins found in the eukaryotic cell. Such proteins have a single transmembrane domain located approximately 30 amino acid residues upstream from the C-terminal end. As a result, the signal recognition particle (SRP) cannot guide a TA protein to the ER membrane for cotranslational insertion. Hence, they are integrated into the ER membrane post-translationally using their C-terminal end as the anchor. TA proteins...

01:07Physiological Pharmacokinetic Models: Incorporating Hepatic Transporter-Mediated Clearance
381
Drug transporters are critical in drug absorption, distribution, and excretion processes. They should be included in physiological-based pharmacokinetic (PBPK) models, which help predict human drug disposition. However, predicting this is challenging during drug development, especially when liver transport is involved. However, with a realistic representation of body transport processes, an accurate model may be possible.
