Insights

Viruses have evolved mechanisms to control programmed cell death (apoptosis) in host cells, impacting viral replication and oncogenesis. Studying these viral strategies enhances our understanding of apoptosis.

Area of Science:

  • Cell Biology
  • Virology
  • Immunology

Background:

  • Apoptosis, or programmed cell death, is a fundamental biological process crucial for development and tissue homeostasis.
  • Cells often undergo apoptosis in response to viral infections, limiting virus propagation.
  • Viruses have developed diverse strategies to evade or manipulate host cell apoptosis.

Purpose of the Study:

  • To review the process of apoptosis and its significance in multicellular organisms.
  • To explore how viral interactions with apoptosis have advanced our understanding of programmed cell death.
  • To detail specific viral mechanisms that interfere with host cell death pathways.

Main Methods:

  • Literature review focusing on viral modulation of apoptosis.
  • Analysis of conserved effector mechanisms and mammalian-specific regulatory pathways.
  • Case studies of viral gene products impacting programmed cell death.

Main Results:

  • Viruses interfere with both conserved and host-specific apoptosis pathways.
  • Viral inhibition of apoptosis provides a survival advantage for the virus.
  • Preventing apoptosis is critical for oncogenic virus-induced host cell transformation.

Conclusions:

  • The study of viruses provides critical insights into the complex mechanisms of apoptosis.
  • Viral interference with apoptosis highlights the intricate interplay between viruses and host cell machinery.
  • Understanding these interactions is key to comprehending viral pathogenesis and oncogenesis.

Apoptosis01:30

Apoptosis

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 reduction of the tissue.
Caspases01:24

Caspases

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside cells.
The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

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...
The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

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. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
Cellular Injury V: Apoptosis and Autophagy01:22

Cellular Injury V: Apoptosis and Autophagy

Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
