Insights

This review explores how programmed cell death (apoptosis) pathways are involved in neurodegenerative diseases. It examines the role of caspases in neuronal development and their regulation during differentiation.

Area of Science:

  • Neuroscience
  • Cell Biology
  • Molecular Biology

Background:

  • Apoptosis plays a crucial role in neurodegenerative diseases, often involving the subversion of normal developmental processes.
  • Various forms of neuronal cell death exist, including autophagic and caspase-independent pathways.
  • The precise mechanisms of apoptosis in neurodegeneration remain incompletely understood.

Purpose of the Study:

  • To review the involvement of apoptotic caspases in neuronal development.
  • To investigate the hypothesis that differentiating neurons exhibit stage-specific changes in apoptosis sensitivity.
  • To explore the role of caspase regulation in these alterations.

Main Methods:

  • Literature review of existing research on apoptosis and neurodegeneration.
  • Analysis of evidence for caspase participation in neuronal development.
  • Examination of data supporting stage-specific alterations in apoptosis sensitivity.

Main Results:

  • Apoptotic caspases are implicated in normal neuronal development.
  • Evidence suggests that differentiating neurons may alter their sensitivity to apoptosis.
  • Caspase regulation appears to be a key factor in these changes.

Conclusions:

  • Understanding caspase regulation in neuronal development is critical for neurodegenerative disease research.
  • Stage-specific apoptosis sensitivity in differentiating neurons is a plausible mechanism.
  • Further research into caspase modulation may offer therapeutic insights for neurodegenerative conditions.

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 cells.
Cellular Injury V: Apoptosis and Autophagy01:22

Cellular 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...
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...
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...
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 reduction of the tissue.
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 20th century...
