Design of bacteriophage T4-based artificial viral vectors for human genome remodeling

Assembly of T4 artificial viral vectors T4-AVVs were assembled by sequential incorporation of purified biomaterials to generate a virus structural mimic (Fig. 2a and Supplementary Movie 1). Starting with an empty capsid shell purified from E. coli infected by the neck-minus and tail-minus T4 phage mutant (10-amber.13-amber.HocΔ.SocΔ T4) (Supplementary Fig. 1a), a pentameric…

Stable expression of large transgenes via the knock-in of an integrase-deficient lentivirus

CLIP enables high-efficiency knock-in into an essential locus To create CLIP, we leverage integrase-deficient lentiviruses (IDLV) to deliver an HDR donor template as a viral RNA genome to cells25,26. IDLV consists of lentiviral components but with a D64V mutation in the integrase, maintaining this enzyme’s ability to package and nuclear…

C698R mutation in Lrsam1 gene impairs nerve regeneration in a CMT2P mouse model

Animal generation The Lrsam1C698R knock-in mice were generated on a C57Bl/6J background using the CRISPR/Cas9 technique. Briefly, single-cell zygotes from C57BL/6J mice were microinjected with mRNA encoding Cas9 and a guide sequence (5′-ACAGCAGCAGACGTGGCCAC-3′ at 20 ng/µl) to target the exon 26 of Lrsam1. A single stranded DNA oligo carrying the C698R mutation…
