Insights

Programmed cell death, including apoptosis and necroptosis, involves key proteins like caspase-8, RIPK1, and RIPK3. These proteins regulate the switch between apoptosis and necroptosis, crucial for cell fate and development.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Biochemistry

Background:

  • Programmed cell death (PCD) encompasses diverse pathways, notably apoptosis and necroptosis.
  • Apoptosis is a genetically controlled process vital for development and eliminating aberrant cells.
  • Necroptosis is a regulated form of necrosis, sharing features with apoptosis.

Purpose of the Study:

  • To review the critical proteins governing the switch between apoptosis and necroptosis.
  • To elucidate the regulatory mechanisms controlling these programmed cell death pathways.

Main Methods:

  • Literature review of programmed cell death pathways.
  • Analysis of key protein involvement in apoptosis and necroptosis.
  • Summary of regulatory roles of specific signaling molecules.

Main Results:

  • Caspase-8, RIPK1, and RIPK3 are identified as crucial regulators.
  • These proteins mediate the transition between apoptotic and necroptotic cell death.
  • Understanding these proteins is key to controlling cell death outcomes.

Conclusions:

  • The interplay of caspase-8, RIPK1, and RIPK3 determines cell fate decisions between apoptosis and necroptosis.
  • This review consolidates current knowledge on these critical regulators.
  • Further research into these pathways may offer therapeutic targets.

Necrosis01:16

Necrosis

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...

Caspases01:24

Caspases

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...

The Intrinsic Apoptotic Pathway01:31

The 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...

Overview of Cell Death01:30

Overview 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...

Apoptosis01:30

Apoptosis

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...

The Extrinsic Apoptotic Pathway01:17

The 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...
