Summary
CRISPR gene editing advances fluke research, enabling genetic manipulation for disease studies. Creating transgenic fluke lines is the next key step for understanding parasite biology and disease.
Area of Science:
- Parasitology
- Molecular Biology
- Genetics
Background:
- CRISPR genome editing is a powerful tool for genetically manipulating parasitic flatworms like schistosomes.
- Understanding fluke biology is crucial for developing effective treatments against diseases they cause.
Purpose of the Study:
- To review the current applications and progress of CRISPR technology in fluke research.
- To identify future research directions and challenges in the field.
Main Methods:
- CRISPR gene knockout (KO) for functional studies.
- Prediction and targeting of safe harbor sites for transgene insertion.
- Development of CRISPR-based diagnostic tools.
Main Results:
- CRISPR KO revealed a liver fluke growth mediator's role in disease progression.
- Genome safe harbor sites identified in Schistosoma mansoni.
- CRISPR diagnostics developed for schistosome and Opisthorchis viverrini infections.
Conclusions:
- CRISPR technology has significantly advanced the study of fluke (patho)biology.
- The next major milestone is the development of heritably transgenic loss-of-function or gain-of-function fluke lines.

Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...
