Summary
Entecavir (ETV) treatment significantly enhances the function of dendritic cells (DCs) in patients with chronic hepatitis B (CHB). This antiviral therapy boosts DC activity, improving their ability to stimulate immune responses against the virus.
Area of Science:
- Immunology
- Virology
- Pharmacology
Background:
- Chronic hepatitis B (CHB) is a significant global health concern.
- Dendritic cells (DCs) play a crucial role in initiating adaptive immune responses.
- Dysfunctional DCs are implicated in the persistence of CHB infection.
Purpose of the Study:
- To investigate the in vitro effects of entecavir (ETV) on dendritic cell (DC) function.
- To assess whether ETV can restore or enhance DC activity in patients with CHB.
- To evaluate the impact of ETV on DC surface marker expression and cytokine production.
Main Methods:
- Dendritic cells (DCs) were generated from peripheral blood mononuclear cells of CHB patients.
- DCs were treated with or without entecavir (ETV).
- Flow cytometry was used to assess DC surface molecules (CD1a, CD80, CD83, HLA-DR).
- ELISA measured IL-6 and IL-12 concentrations.
- Lymphocyte proliferation assays evaluated DC stimulatory capacity.
Main Results:
- ETV treatment increased the expression of DC surface markers CD1a, CD80, CD83, and HLA-DR.
- ETV-treated DCs secreted significantly higher levels of IL-12 and lower levels of IL-6.
- The ability of DCs to stimulate allogeneic lymphocyte proliferation was enhanced by ETV.
Conclusions:
- Entecavir (ETV) enhances the biological activity of dendritic cells (DCs) derived from CHB patients.
- ETV may improve DC-mediated immune responses in the context of CHB infection.
- These findings suggest a potential immunomodulatory role for ETV beyond its direct antiviral activity.

01:25Hepatitis
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. The...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
01:25Inhibitors Of Virion Release
Viral replication and dissemination rely on efficient mechanisms for host cell entry, genome replication, assembly, and release. Influenza viruses, such as types A and B, are negative-sense single-stranded RNA viruses with a segmented genome, that depend on two critical surface glycoproteins to carry out these processes: hemagglutinin (HA) and neuraminidase (NA). HA initiates infection by binding to sialic acid residues on the surface of host epithelial cells, facilitating receptor-mediated...
01:19Inhibitors of Virion Maturation and Assembly
As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...
01:30Inhibitors of Viral Protein Synthesis
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
02:33Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
