How Can Genome Editing Aid in the Fight Against a Virus?
When SARS-CoV-2 was discovered, numerous researchers focused on investigating this novel virus and the disease it caused.
FREMONT, CA: CRISPR researchers were no exception, and the gene-editing technique was quickly thrust into the forefront of the global struggle against COVID-19. The CRISPR—Cas system is based on a naturally existing bacterial gene-editing mechanism that plays a critical role in the prokaryotic defense against viral infection. The issue for researchers now is to determine the optimal way to leverage its inherent potential and enhance it for human benefit.
Here, scientists have indeed risen to the challenge, successfully developing quick diagnostic tests for COVID-19 and obtaining their first US FDA (MD, USA) approval. The research continues as similar tests are being designed for wider clinical use, with numerous businesses vying to fill the ever-widening market gap created by reagents for PCR-based COVID-19 tests running out and testing capacity reducing. Scientists have investigated CRISPR as a possible treatment in other fields, harnessing its tailored enzymatic activity to degrade SARS-CoV-2 RNA and limit viral replication.
