Summary
Understanding severe acute respiratory syndrome (SARS) involves studying its pathological mechanisms. Research shows that mitogen-activated protein kinases (MAPKs) are key in SARS-CoV-infected cells, influencing cell survival or death.
Area of Science:
- Virology
- Cell Biology
- Immunology
Background:
- Severe acute respiratory syndrome (SARS) is a critical infectious disease caused by the SARS coronavirus (SARS-CoV).
- High mortality rates necessitate a deep understanding of SARS pathogenesis for effective prevention.
- SARS-CoV infection triggers complex cellular responses, including apoptosis and survival pathways.
Purpose of the Study:
- To review recent advancements in SARS-CoV biology.
- To elucidate the role of signal transduction pathways in SARS-CoV-infected cells.
- To highlight the importance of mitogen-activated protein kinases (MAPKs) in SARS pathogenesis.
Main Methods:
- Review of current scientific literature on SARS-CoV.
- Analysis of cellular signaling pathways activated by SARS-CoV infection.
- Investigation of the roles of Akt and p38 MAPK in infected cells.
Main Results:
- SARS-CoV infection activates specific signaling pathways, leading to molecular phosphorylation.
- Conflicting cellular programs, apoptosis and survival, are observed in SARS patients.
- Activation of MAPKs is crucial for cytokine expression and apoptosis in SARS-CoV-infected cells.
- Akt and p38 MAPK are identified as critical determinants of cell fate in vitro.
Conclusions:
- MAPK signaling pathways are central to the cellular response to SARS-CoV.
- Targeting these signaling cascades holds potential for developing anti-SARS-CoV therapeutics.
- Further research into SARS-CoV signal transduction is vital for disease control.

01:29Coronavirus
Coronaviruses, including the severe acute respiratory syndrome coronavirus (SARS-CoV), are enveloped viruses characterized by their single-stranded, positive-sense RNA genome and helical nucleocapsid structure. The hallmark of these viruses is their club-shaped spike (S) glycoproteins that protrude from the viral envelope, facilitating attachment to host cells. Typically, coronaviruses infect the upper respiratory tract, often causing mild or asymptomatic disease. However, certain strains like...
01:20The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:22Amplifying Signals via Enzymatic Cascade
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
01:24Intracellular Signaling Cascades
Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...
