Abstract:
Since the initial description of apoptosis, a number of different forms of cell death have been described. In this review we will focus on classic caspase-dependent apoptosis and its variations that contribute to diseases. Over fifty years of research have clarified molecular mechanisms involved in apoptotic signaling as well and shown that alterations of these pathways lead to human diseases. Indeed both reduced and increased apoptosis can result in pathology. More recently these findings have led to the development of therapeutic approaches based on regulation of apoptosis, some of which are in clinical trials or have entered medical practice.
Insights
This review explores programmed cell death (apoptosis) and its role in disease. Understanding apoptosis pathways is crucial for developing new disease treatments, with some therapies already in use.
Area of Science:
- Cell Biology
- Molecular Biology
- Pathology
Background:
- Apoptosis, or programmed cell death, is a fundamental biological process.
- Over fifty years of research have elucidated the molecular mechanisms of apoptotic signaling.
Purpose of the Study:
- To review classic caspase-dependent apoptosis and its disease-related variations.
- To highlight the link between altered apoptotic pathways and human diseases.
- To discuss therapeutic strategies targeting apoptosis regulation.
Main Methods:
- Literature review focusing on caspase-dependent apoptosis.
- Analysis of molecular mechanisms underlying apoptotic signaling.
- Examination of the role of apoptosis dysregulation in various pathologies.
Main Results:
- Alterations in apoptotic pathways are implicated in a wide range of human diseases.
- Both reduced and excessive apoptosis can lead to pathological conditions.
- Dysregulation of apoptosis contributes to disease development and progression.
Conclusions:
- Understanding apoptosis is key to understanding disease.
- Targeting apoptosis pathways offers promising therapeutic avenues.
- Several apoptosis-regulating therapies are advancing through clinical trials and medical practice.

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...
