For example, a PEGylated phospholipid, namely 1,2-distearoyl-sn-glycero-3-phosphatidylethanolamine-N-[methoxy(polyethylene glycol)-2000] (DSPE-PEG2k) self-assembled with human glucagon-like peptide-1 (GLP-1) to form micelles (hydrodynamic size =  ~ 15 nm) in aqueous solutions, which was subcutaneously injected into ALI mice after exposure to aerosolized LPS, showing dose-dependent reversal in lung hyper-inflammatory responses [171]. This evidence concerns the gene GCG and acute respiratory distress syndrome.
