Apoptosis in viral hepatitis B and C
Chang Gung Medical Journal
|August 2, 2001
Summary
Tumor necrosis factor (TNF) and TNF receptors (TNFR) play key roles in viral hepatitis. Viruses manipulate apoptosis, a cell death process, to evade immune responses and spread infection.
Area of Science:
- Immunology
- Virology
- Cell Biology
Background:
- Tumor necrosis factor (TNF) and TNF receptors (TNFR) are crucial in apoptosis, viral pathogenesis, and immune regulation.
- Apoptosis plays a significant role in the pathogenesis of viral hepatitis B and C.
- TNF's modulation of viral infections has been previously reported, but recent insights into TNFR signaling pathways offer deeper understanding.
Purpose of the Study:
- To review the mechanism of apoptosis in viral hepatitis B and C.
- To elucidate the role of viral proteins in regulating apoptosis during these infections.
- To understand how viruses interact with cellular machinery downstream of TNFR signaling.
Main Methods:
- Review of existing literature on TNF, TNFR signaling, and apoptosis.
- Analysis of molecular interactions between viral proteins and cellular components.
- Examination of how viral factors manipulate the TNFR pathway.
Main Results:
- Viral proteins interact with intracellular components downstream of TNFR signaling.
- Viruses can manipulate cellular machinery to evade immune surveillance.
- This manipulation facilitates the spread of viral infection.
Conclusions:
- Apoptosis regulation by viral proteins is a critical factor in viral hepatitis B and C pathogenesis.
- Understanding these molecular interactions is key to developing therapeutic strategies.
- Viruses actively subvert host cell processes, including apoptosis, for their own propagation.

1.1K
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...

01:29Immune Response Against Viral Pathogens
2.2K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

16.2K
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

01:17The Extrinsic Apoptotic Pathway
9.0K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

01:17Phagocytosis of Apoptotic Cells
5.4K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.

7.7K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
