Finally, aerosol formulations of anionic liposomes coated with N-(2-hydroxy)propyl-3-trimethyl ammonium CH chloride were loaded with Ghrelin (GHRL) and proposed as potential tool for cachexia treatment, showing an enhanced GHRL permeation through the Calu3 epithelial monolayer and increased bioadhesion [109]. This evidence concerns the gene GHRL and Cachexia.
