Abstract

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.

Claims

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.
