Described is an “artificial virus” (AV) programmed with biomolecules that can enter human cells and carry out precise human genome modification. The AVs comprise: at least one viral vector, such as bacteriophage T4; at least one therapeutic molecule, such as DNA, RNA, protein and their complex; and a lipid coating. Also described is a method of human genome modification, using such an AV, and a method of program such an AV.

The invention relates to the production of phage and non-replicative transduction particles using DNAs (eg, plasmids and helper phage, mobile genetic elements (MGEs) or plasmids with chromosomally integrated helper phage genes), as well as the phage, helper phage, kits, compositions and methods involving these. The non-replicative transduction particles can be used to deliver antibacterial agents comprising a guided nuclease system.

The present disclosure provides systems for modulating drug metabolism, specifically in the gut microbiome, by modifying target cell/s and/or population of cells comprising the target cell/s. The disclosed systems comprise the following components: (a) at least one drug metabolism modulating component comprising at least one nucleic acid sequence encoding and/or modulating at least one element participating in metabolism of at least one drug, at least one cas gene and at least one Clustered. Regularly Interspaced Short Palindromic Repeat (CRISPR) array; and (b) at least one selective component comprising at least one protospacer. The at least one protospacer is targeted by at least one spacer of the CRISPR array of (a), thereby inactivating said selective component. The present disclosure further provides, compositions and methods using the disclosed systems and any components thereof in modulation of drug metabolism and in therapeutic applications.
