Abstract:
Apoptosis is a form of regulated cell death (RCD) that involves proteases of the caspase family. Pharmacological and genetic strategies that experimentally inhibit or delay apoptosis in mammalian systems have elucidated the key contribution of this process not only to (post-)embryonic development and adult tissue homeostasis, but also to the etiology of multiple human disorders. Consistent with this notion, while defects in the molecular machinery for apoptotic cell death impair organismal development and promote oncogenesis, the unwarranted activation of apoptosis promotes cell loss and tissue damage in the context of various neurological, cardiovascular, renal, hepatic, infectious, neoplastic and inflammatory conditions. Here, the Nomenclature Committee on Cell Death (NCCD) gathered to critically summarize an abundant pre-clinical literature mechanistically linking the core apoptotic apparatus to organismal homeostasis in the context of disease.
Insights
Apoptosis, a regulated cell death process involving caspases, is crucial for development and tissue balance. Dysregulation of apoptosis contributes to diseases ranging from cancer to neurological disorders.
Area of Science:
- Cell Biology
- Biochemistry
- Pathology
Background:
- Apoptosis, or programmed cell death, is a fundamental biological process mediated by caspase proteases.
- This process is essential for normal development, tissue homeostasis, and eliminating damaged cells.
- Aberrations in apoptosis are implicated in numerous human diseases, including cancer and neurodegeneration.
Purpose of the Study:
- To critically review preclinical literature on the role of apoptosis in disease.
- To summarize the mechanistic links between the apoptotic machinery and organismal homeostasis.
- To provide a consensus on the involvement of apoptosis in various pathological conditions.
Main Methods:
- Systematic review of abundant preclinical research.
- Critical analysis of studies investigating apoptosis inhibition and activation.
- Synthesis of mechanistic data linking apoptotic pathways to disease etiology.
Main Results:
- Apoptosis plays a dual role: its defects impair development and promote cancer, while its excessive activation causes tissue damage in various diseases.
- The core apoptotic apparatus is mechanistically linked to maintaining organismal homeostasis.
- Evidence supports the involvement of apoptosis in neurological, cardiovascular, renal, hepatic, infectious, neoplastic, and inflammatory conditions.
Conclusions:
- Apoptosis is a critical regulator of health and disease, with its dysregulation contributing to a wide spectrum of human disorders.
- Understanding the intricate role of apoptosis is vital for developing therapeutic strategies targeting cell death pathways.
- The Nomenclature Committee on Cell Death (NCCD) emphasizes the central role of apoptosis in disease pathogenesis.

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...
