Summary
Programmed cell death is crucial for development, regulating cell numbers and removing harmful cells. Studies in model organisms reveal conserved genetic pathways controlling cell death in mammals.
Area of Science:
- Developmental Biology
- Genetics
- Cell Biology
Background:
- Programmed cell death (PCD) is essential for multicellular organisms to regulate cell populations and eliminate compromised cells.
- Evolutionarily conserved genetic pathways for PCD, identified in model organisms like C. elegans and Drosophila, provide insights into mammalian cell death.
- Understanding PCD mechanisms is vital for development and disease research.
Purpose of the Study:
- To explore the fundamental role of programmed cell death in multicellular development.
- To highlight the utility of model organisms in understanding conserved cell death pathways.
- To delineate the cell-autonomous and non-autonomous mechanisms regulating developmental cell death.
Main Methods:
- Comparative genetic analysis across species (C. elegans, Drosophila, mammals).
- Investigation of conserved biochemical and genetic regulatory pathways.
- Identification of cell-autonomous and non-autonomous regulatory mechanisms.
Main Results:
- Programmed cell death is a fundamental process for regulating cell numbers and eliminating detrimental cells during development.
- Conserved genetic pathways from lower species serve as effective models for studying mammalian cell death.
- Both cell-autonomous and non-autonomous mechanisms regulate developmental cell death, which can be pre-determined or result from altered cell interactions.
Conclusions:
- Developmental cell death is a highly regulated process with conserved genetic underpinnings.
- Model organism studies are invaluable for deciphering complex cellular processes like programmed cell death in mammals.
- Cell death regulation involves intricate interactions influencing cell fate, impacting development and organismal health.

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...

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.
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.
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...
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...
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...
