               1. A method for delivering lipid nanoparticles (LNPs) to the lungs of a subject suffering from or at risk for primary ciliary dyskinesia (PCD), wherein the method comprises nebulizing a liquid pharmaceutical composition to generate an aerosolized pharmaceutical composition, and administering the aerosolized pharmaceutical composition to the subject, 
            wherein the liquid pharmaceutical composition comprises lipid nanoparticles (LNPs) having: 
                (a) mRNA integrity of between 75% and 99%, and 
                  (b) a diameter between 20 nm and 600 nm, 
                wherein the LNPs comprise an ionizable lipid, a phospholipid, a PEG-lipid, and a sterol, 
                wherein the LNPs comprise mRNA encoding a dynein axonemal intermediate chain 1 (DNAI1) protein, 
                wherein the aerosolized pharmaceutical composition comprises aerosol particles having: 
                (a) a mass median aerodynamic diameter (MMAD) between 1 μm and 10 μm, 
                  (b) a geometric standard deviation (GSD) between 1 and 5, and 
                  (c) a fine particle fraction (FPF) percent of at least 50%, and 
                wherein the aerosolized particles are selectively delivered to the tracheobronchial region of the lung of the subject.
