Summary
Programmed cell death (PCD) is crucial in microbes for development and differentiation. Understanding PCD pathways may help combat antimicrobial drug resistance and develop new therapies.
Area of Science:
- Microbiology
- Cell Biology
- Evolutionary Biology
Background:
- Programmed cell death (PCD) is a fundamental biological process observed in both multicellular and unicellular organisms.
- Eukaryotic microbes utilize diverse PCD pathways, including apoptosis-like, necrosis, and autophagic death, for developmental regulation.
- PCD plays a role in cellular differentiation and has evolutionary links to multicellularity.
Purpose of the Study:
- To provide an overview of programmed cell death (PCD) pathways in microbes.
- To highlight novel components of the PCD molecular machinery.
- To explore the role of PCD in microbial differentiation and its evolutionary origins.
Main Methods:
- Literature review and synthesis of existing research on PCD in microbes.
- Analysis of molecular mechanisms underlying various PCD pathways.
- Examination of evolutionary scenarios for PCD emergence and maintenance.
Main Results:
- Identified diverse PCD mechanisms in microbes, such as apoptosis-like, programmed necrosis, and autophagic death.
- Highlighted new molecular players involved in PCD regulation.
- Demonstrated a link between PCD defects and antimicrobial drug resistance.
Conclusions:
- Programmed cell death is a vital process in microbial development and differentiation.
- Understanding PCD offers potential for developing novel therapeutic strategies against drug-resistant microbes.
- Further research into PCD pathways may lead to the discovery of agents that modulate endogenous cell suicide mechanisms.

01:30Overview 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...

01:11Cellular Injury IlI: Cellular Death
Cell death is the irreversible loss of cellular structure and function, representing the final stage of severe injury. It plays a key role in both normal physiology and disease.Types of Cell DeathThe two main types are necrosis and apoptosis, though others like necroptosis and pyroptosis also exist.Necrosis:Necrosis is an unregulated form of cell death caused by severe injury such as trauma, toxins, or ischemia. It is characterized by cell swelling, membrane loss, rupture, and leakage of...
01:22Cellular 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...
01:16Necrosis
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 anucleated and die, but their...

01:18Autophagic Cell Death
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.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and pro-apoptotic...

01:30Apoptosis
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.
