Giardia duodenalis causes widespread giardiasis, and existing treatments often fail. This study reviews Giardia telomeres and telomerase, exploring them as potential new therapeutic targets to combat this persistent parasitic infection.
Area of Science:
- Parasitology
- Molecular Biology
- Genomics
Background:
- Giardia duodenalis causes significant global diarrheal disease.
- Current treatments for giardiasis have high rates of therapeutic failure.
- New therapeutic targets are urgently needed for effective giardiasis treatment.
Purpose of the Study:
- To compile current knowledge on Giardia telomeres and telomerase.
- To highlight unique features of these structures in Giardia.
- To evaluate targeting telomeres/telomerase as a novel therapeutic strategy.
Main Methods:
- Literature review of Giardia telomeres and telomerase (until 2023).
- Analysis of genomic stability mechanisms in Giardia.
- Exploration of parasite-specific cellular processes.
Main Results:
- Giardia chromosomes are capped by small telomeres, protected by specific proteins.
- Giardia exhibits constant telomerase activity to maintain proliferation.
- Telomeres are involved in G-quadruplex formation and transposable elements.
Conclusions:
- Understanding Giardia telomeres and telomerase is limited but crucial.
- These structures and their associated enzymes present potential therapeutic targets.
- Targeting Giardia telomeres/telomerase could offer an innovative treatment approach.
