Fusogenic lipid nanoparticles for target cell-specific production of a therapeutic protein

Provided nucleic acid-based expression construct for the target cell-specific production of a therapeutic protein, such as a pro-apoptotic protein, within a target cell, including a target cell that is associated with aging, disease, or other condition, in particular a target cell that is a senescent cell or a cancer cell. Also provided are formulations and systems, including fusogenic lipid nanoparticle (LNP) formulations and systems, for the delivery of nucleic acid-based expression constructs as well as methods for making and using such nucleic acid-based expression constructs, formulations, and systems for reducing, preventing, and/or eliminating the growth and/or survival of a cell, such as a senescent cell and/or a cancer cell, which is associated with aging, disease, or other condition as well as methods for the treatment of aging, disease, or other conditions by the in vivo administration of a formulation, such as a fusogenic LPN formulation, comprising an expression construct for the target cell-specific production of a therapeutic protein, such as a pro-apoptotic protein, in a target cell that is associated with aging, disease, or other condition, in particular a target cell that is a senescent cell or a cancer cell.

OPTIMIZED CRISPR/CAS9 SYSTEMS AND METHODS FOR GENE EDITING IN STEM CELLS
20230126434 · 2023-04-27 ·

The methods and compositions described herein surprisingly increase CRISPR/Cas-mediated gene editing in stem cells by transiently treating the cells with a stem cell viability enhancer prior to and/or after contacting the cells with one or more CRISPR/Cas9 components. Further, this treatment also surprisingly results in increased engraftment of the stem cells into the target tissue of a subject. The present disclosure also provides one or more modified CRISPR/Cas9 components which, when used in combination with the stem cell viability enhancer, further increases the frequency of gene editing in stem cells, increases stem cell viability, and increases stem cell engraftment.
