The Takeaway
CRISPR usually acts like a shotgun that goes everywhere, risking side effects in healthy tissue. This magnetically gated virus stays dormant until it reaches a specific location, making localized immunotherapy much safer and more precise.
From the abstract
Precise control of genome editing activity in vivo remains a major barrier to the clinical translation of CRISPR-based therapeutics, as current approaches cannot reliably restrict editing activity to target tissues. Here we show that a magnetically gated baculoviral CRISPR platform enables spatial control of genome editing activity. By coupling magnetic activation of viral transduction at target sites with complement-mediated inactivation of circulating vectors, this system functionally confines
