Abstract:
Caspases form a family of cysteine proteases which are implicated in multiple forms of apoptosis. Their role has been intensively studied during apoptosis triggered by death receptors, but their exact biological functions and mechanisms of activation remain unclear. Here, we summarize the knowledge about the signal transduction pathways of death receptors leading to the activation of caspases as the key effector components of apoptotic cell death.
Insights
Caspases, crucial proteases in apoptosis, are activated by death receptor signaling. This review summarizes pathways leading to caspase activation in programmed cell death.
Area of Science:
- Biochemistry
- Molecular Biology
- Cell Biology
Background:
- Caspases are cysteine proteases central to apoptosis (programmed cell death).
- Their involvement in death receptor-mediated apoptosis is well-established.
- However, precise biological roles and activation mechanisms require further elucidation.
Purpose of the Study:
- To review signal transduction pathways of death receptors.
- To elucidate mechanisms of caspase activation.
- To highlight caspases as key effectors in apoptotic cell death.
Main Methods:
- Literature review and synthesis of existing research.
- Analysis of signal transduction pathways.
- Focus on death receptor-mediated apoptosis.
Main Results:
- Detailed summary of death receptor signaling cascades.
- Identification of key regulatory steps in caspase activation.
- Emphasis on the effector functions of caspases in apoptosis.
Conclusions:
- Caspase activation is a critical endpoint of death receptor signaling.
- Understanding these pathways is essential for comprehending apoptotic mechanisms.
- Further research is needed to fully clarify caspase functions and activation intricacies.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
