Summary
Programmed cell death (PCD) pathways significantly impact aging. Dysregulation of PCD contributes to aging phenotypes, offering potential therapeutic targets for age-related diseases.
Area of Science:
- Cellular Biology
- Aging Research
- Pathology
Background:
- Programmed cell death (PCD) is vital for tissue homeostasis, particularly in rapidly dividing tissues like blood and gut lining.
- Aging is associated with dysregulation of PCD, leading to either insufficient cell death (cancer, senescence) or excessive cell death (atrophy, degeneration).
Purpose of the Study:
- To explore the multifaceted role of PCD pathways in aging phenotypes.
- To identify PCD pathways as potential therapeutic targets for interventions in aging and age-related diseases.
Main Methods:
- Review of existing evidence on PCD pathways and aging.
- Analysis of how altered PCD impacts tissue function and lifespan during aging.
Main Results:
- Accumulated cellular damage and signaling errors during aging disrupt normal PCD.
- Imbalances in PCD contribute to diseases such as cancer, tissue atrophy, and neurodegeneration.
Conclusions:
- Modulating PCD pathways presents a promising strategy for combating aging and associated pathologies.
- Reactivating PCD may target senescent and cancerous cells, while inhibiting PCD could mitigate tissue degeneration.

01:30Overview of Cell Death
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
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...

01:30Apoptosis
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.
01:22Cellular Injury V: Apoptosis and Autophagy
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
01:17The 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...
01:18Autophagic Cell Death
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
