Pulmonary delivery of mRNA
View Patent ↗Disclosed herein are compositions and methods for modulating the production of a protein in a target cell. The compositions and methods disclosed herein are capable of ameliorating diseases associated with protein or enzyme deficiencies.
1. A method of delivery of messenger RNA (mRNA) for in vivo expression of protein, comprising
administering via inhalation from a nebulizer to a subject a composition comprising an mRNA encoding full-length exogenous CFTR protein such that the administering of the composition results in in vivo expression of the full-length exogenous CFTR protein encoded by the mRNA in lung cells of the subject, wherein the composition further comprises polyethylenimine (PEI).
2. The method of claim 1 , wherein the mRNA comprises a non-naturally occurring nucleotide.
3. The method of claim 1 , wherein the mRNA comprises pseudouridine.
4. A method of delivery of messenger RNA (mRNA) for in vivo expression of protein, comprising
administering via inhalation from a nebulizer to a subject a composition comprising an mRNA encoding full-length exogenous CFTR protein such that the administering of the composition results in in vivo expression of the full-length exogenous CFTR protein encoded by the mRNA in lung cells of the subject,
wherein the mRNA encoding the full-length exogenous CFTR protein is encapsulated in a liposome comprising one or more cationic lipids, one or more non-cationic lipids, one or more cholesterol-based lipids and one or more PEG-modified lipids.
5. The method of claim 4 , wherein the mRNA comprises a non-naturally occurring nucleotide.
6. The method of claim 4 , wherein the mRNA comprises pseudouridine.
