Pathogens manipulate programmed cell death, including apoptosis, necrosis, and pyroptosis, to survive infections. This review details host cell death pathways and pathogen strategies for controlling them.
Area of Science:
- Immunology
- Cell Biology
- Microbiology
Background:
- Programmed cell death is crucial for host defense against infections.
- Pathogens evolve mechanisms to evade or exploit host cell death pathways.
- Apoptosis, necrosis, and pyroptosis are key cell death modalities in infection.
Purpose of the Study:
- To review signaling pathways of major host cell death mechanisms.
- To provide an overview of pathogen strategies for manipulating cell death.
- To understand host-pathogen interactions at the cellular level.
Main Methods:
- Literature review of signaling pathways.
- Analysis of virulence factors and toxins.
- Discussion of host-pathogen interactions.
Main Results:
- Detailed description of apoptosis, necrosis, and pyroptosis signaling.
- Examples of pathogen manipulation of cell death pathways.
- Identification of common and unique pathogen strategies.
Conclusions:
- Pathogen manipulation of cell death is a critical factor in infectious disease.
- Understanding these mechanisms can reveal new therapeutic targets.
- Further research into host-pathogen cell death interplay is warranted.

Overview of Cell Death
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...

Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...
