Summary
Programmed cell death (PCD) encompasses nearly 15 types, with apoptosis being the most studied. This review details apoptotic pathways, highlighting the roles of cellular membranes and the integration point of mitochondrial permeabilization and caspase activation.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Programmed cell death (PCD) is crucial for development and homeostasis.
- Apoptosis is the most characterized form of PCD, involving specific molecular pathways.
- Cellular membranes and organelles are key players in regulating cell fate.
Purpose of the Study:
- To review and analyze diverse apoptotic pathways.
- To elucidate the roles of cellular membranes and organelles in apoptosis.
- To describe the integration of various apoptotic signals.
Main Methods:
- Literature review of programmed cell death mechanisms.
- Analysis of apoptotic pathways involving cellular organelles.
- Description of caspase cascades and their regulation.
Main Results:
- Multiple apoptotic pathways exist, involving plasma membrane and organelles like mitochondria, ER, Golgi, lysosomes, and nucleus.
- Caspase cascades are central to apoptotic execution.
- Mitochondrial membrane permeabilization and caspase activation are common integration points.
Conclusions:
- Apoptotic pathways are interconnected, with potential for cross-talk.
- Mitochondrial outer membrane permeabilization and caspase activation represent a convergence point for apoptotic signaling.
- Understanding these pathways is vital for cell death research.

01:30Apoptosis
16.9K
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...

01:31The Intrinsic Apoptotic Pathway
9.2K
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...

01:17The Extrinsic Apoptotic Pathway
9.3K
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...

01:24Caspases
14.5K
Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside...

01:30Overview of Cell Death
11.1K
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...

01:17Phagocytosis of Apoptotic Cells
5.6K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.
