A significant challenge is to process them using scalable technologies into useful scaffolds that provide control over fibre diameter, morphology, mechanical properties, ion release, degradation and cell response. In this work we develop formulations that are amenable to The invention relates to mRNA therapy for the treatment of cystic fibrosis. mRNAs for use in the invention, when administered in vivo, encode cystic fibrosis transmembrane conductance regulator (CFTR), isoforms thereof, functional fragments thereof, and fusion proteins comprising CFTR. mRNAs of the invention are preferably encapsulated in lipid nanoparticles (LNPs) to effect efficient delivery Retinal ganglion cells (RGCs) consume large quantities of energy to convert light information into a neuronal signal, which makes them highly susceptible to hypoxic injury.

To address this issue, three common cross-linkers; tripolyphosphate (TPP), dextran sulphate (DS) and poly-D-glutamic acid (PGA) were used to prepare siRNA loaded CS-TPP/DS/PGA nanoparticles by ionic gelation method. In order to perform this assay, human nasal septum carcinoma cell line RPMI 2650 (Sigma Aldrich) (2 × 10 5 cells/mL) was plated in 96-wells plates (Corning Inc., Corning, NY, USA) and cultured in a humidified incubator at 37 °C in a 5% CO 2 atmosphere for 24 h to facilitate adhesion .
