Summary
Multicellular organisms use programmed cell death to maintain tissue health. Recent studies in Drosophila melanogaster suggest conserved mitochondrial pathways regulate this essential process.
Area of Science:
- Cell Biology
- Developmental Biology
- Genetics
Background:
- Cell death is crucial for tissue homeostasis in multicellular organisms.
- Dysregulation of cell death contributes to diseases like cancer and neurodegeneration.
- Model organisms like Caenorhabditis elegans have elucidated key programmed cell death regulators.
Purpose of the Study:
- To investigate the mechanisms of programmed cell death regulation in Drosophila melanogaster.
- To identify conserved molecular pathways involved in cell death in Drosophila.
Main Methods:
- Molecular analyses
- Cellular analyses
Main Results:
- Drosophila melanogaster has unique cell death regulators.
- Evidence suggests a canonical mitochondrial pathway is involved in Drosophila programmed cell death.
- These mechanisms may offer insights into conserved metazoan cell death processes.
Conclusions:
- Programmed cell death in Drosophila involves conserved mitochondrial pathways.
- Further research in Drosophila can illuminate fundamental cell death mechanisms across metazoans.

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...

01:30Apoptosis
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...

01:17The 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...

01:30Overview 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...

01:18Autophagic Cell Death
5.0K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:16Necrosis
7.2K
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...
