👉 Virus engineering is a sophisticated field that involves the deliberate modification of viral genomes to create new or altered viruses with specific properties. This process can be used for various purposes, including developing vaccines, creating oncolytic viruses for cancer therapy, and studying viral mechanisms. Scientists employ techniques such as CRISPR-Cas9 gene editing, homologous recombination, and synthetic biology to introduce, delete, or modify genetic material within viruses. These modifications can enhance the virus's ability to deliver therapeutic payloads, improve its targeting specificity, or attenuate its pathogenicity. By carefully controlling the genetic changes, researchers can harness the natural infectivity and replication capabilities of viruses to achieve desired outcomes in medicine, biotechnology, and fundamental research.
