Apoptosis : an International Journal on Programmed Cell Death
|November 30, 2023
Summary
Eryptosis, a programmed cell death in red blood cells, shares similarities but has key differences with apoptosis. Understanding these distinctions is vital for new therapeutic strategies.
Area of Science:
- Cell Biology
- Physiology
Background:
- Eryptosis, a regulated cell death (RCD) in erythrocytes, was initially viewed as analogous to apoptosis in nucleated cells.
- Recent research highlights significant differences between eryptosis and apoptosis, necessitating a deeper comparative analysis.
Approach:
- This review systematically compares the hallmarks of eryptosis and apoptosis.
- It critically examines dissimilarities in signaling pathways, including caspase-3, Ca2+ and ROS signaling.
- The distinct roles of kinases like casein kinase 1α, protein kinase C, Janus kinase 3, cyclin-dependent kinase 4, and AMP-activated protein kinase in each process are discussed.
Key Points:
- Key differences emerge in caspase-3 activation, calcium and reactive oxygen species signaling.
- Opposing roles of specific kinases (casein kinase 1α, protein kinase C, JAK3, CDK4, AMPK) distinguish eryptosis from apoptosis.
- Erythrocytes exhibit unique programmed cell destruction mechanisms.
Conclusions:
- Further research is crucial to elucidate the nuances of cell death in nucleated versus enucleated cells.
- Identifying cell type-specific death patterns can guide the development of novel therapeutic agents targeting cell death pathways.

01:30Apoptosis
11.5K
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...

01:30Overview of Cell Death
7.3K
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...

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

01:24Caspases
12.5K
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...

01:17The Extrinsic Apoptotic Pathway
6.4K
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...

01:31The Intrinsic Apoptotic Pathway
6.6K
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...
