Abstract:
Programmed cell death is an essential mechanism of the host to combat infectious agents and to regulate immunity during infection. Consequently, activation and deactivation of the hosts' cell death pathways by protozoan parasites play critical roles in parasite control, pathogenesis, immune evasion and parasite dissemination within the host. Here, we discuss advances in the understanding of these fascinating host-parasite interactions with special emphasis on how protozoa can modulate the cell death apparatus of its host.
Insights
Protozoan parasites manipulate host programmed cell death pathways to evade immune responses and spread. Understanding these interactions is key to controlling infections and disease progression.
Area of Science:
- Immunology
- Parasitology
- Cell Biology
Background:
- Programmed cell death is a vital host defense against pathogens.
- Protozoan parasites have evolved mechanisms to interfere with host cell death pathways.
Purpose of the Study:
- To review current understanding of protozoan modulation of host cell death.
- To highlight the significance of these interactions in infection.
Main Methods:
- Literature review and synthesis of existing research on host-parasite interactions and cell death.
Main Results:
- Protozoa actively manipulate host apoptosis and other cell death mechanisms.
- Modulation of cell death impacts parasite control, pathogenesis, and dissemination.
- Specific examples of protozoan strategies for immune evasion via cell death manipulation are discussed.
Conclusions:
- Host cell death pathways are critical battlegrounds in protozoan infections.
- Targeting these parasite-mediated manipulations offers potential therapeutic strategies.

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...

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
