Insights

Reovirus infections trigger programmed cell death (apoptosis) in various cells and tissues, leading to disease. Inhibiting this apoptosis may offer a new way to reduce reovirus-induced tissue damage.

Area of Science:

  • Virology
  • Pathogenesis
  • Cell Biology

Background:

  • Reovirus infections serve as a model for studying virus-induced disease mechanisms.
  • Reoviruses are known to induce apoptosis in numerous cell types in vitro and in vivo.
  • Apoptosis, viral infection, and tissue injury are observed to occur together in vivo.

Purpose of the Study:

  • To review the mechanisms by which reoviruses induce apoptosis.
  • To explore the potential of inhibiting apoptosis as a therapeutic strategy against reovirus-induced tissue damage.

Main Methods:

  • Literature review of studies on reovirus infection and apoptosis.
  • Analysis of in vitro and in vivo experimental data on reovirus pathogenesis.
  • Investigation of cellular pathways involved in reovirus-induced apoptosis.

Main Results:

  • Reovirus infection consistently induces apoptosis across various cell types and target organs.
  • The colocalization of infection, injury, and apoptosis suggests a causal role for apoptosis in disease.
  • Specific molecular mechanisms underlying reovirus-induced apoptosis are being elucidated.

Conclusions:

  • Apoptosis is a key mechanism in reovirus-induced pathogenesis.
  • Targeting apoptosis inhibition presents a promising avenue for limiting reovirus-related tissue damage.
  • Further research into apoptosis pathways could lead to novel antiviral therapies.

Leaky Scanning02:28

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R stands for...
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...
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.
Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

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...
