Lipid formulations for delivery of messenger RNA
First Claim
1. A method of delivery of messenger RNA (mRNA) in vivo, comprising administering to a subject in need of delivery a composition comprising an mRNA encoding a human survival of motor neuron-1 (hSMN-1) protein, encapsulated within a liposome such that the administering of the composition results in the expression of the protein encoded by the mRNA in vivo;
- wherein the liposome comprises a cationic lipid of formula I-c;
