Bacterial Protoplast-Derived Nanovesicles Carrying CRISPR Cas9 Tools Efficiently Re-educate Tumor-Associated Macrophages for Cancer Immunotherapy


ABSTRACT: we developed an in vivo CRISPR-Cas9 genome editing system that targets tumor-associated macrophages (TAMs) via bacterial protoplast-derived nanovesicles (NVs) decorated with a pH-responsive PEG conjugated polymer and galactosamine-conjugated ligand

ORGANISM(S): Escherichia Coli Bl21(de3)

The CRISPR-Cas9 system offers substantial potential for cancer therapy by enabling precise manipulation of key genes involved in tumorigenesis and immune response. Despite its promise, the system faces critical challenges, including the preservation of cell viability post-editing and ensuring safe in vivo delivery. To address these issues, this study develops an in vivo CRISPR-Cas9 system targeting tumor-associated macrophages (TAMs). We employ bacterial protoplast-derived nanovesicles (NVs) mod  ...[more]
