GALA is a pH-responsive amphipathic peptide consisting of 30 amino acids, which acts as a lung endothelium-targeting ligand. GALA undergoes a conformational transition from random coil to α-helix in an acidic environment at pH 5.0, thereby inducing endosomal membrane destabilization and fusion. GALA-modified liposomes traverse lung endothelial cells via clathrin-dependent endocytosis and transcytosis, and specifically accumulate in the lungs after intravenous injection. GALA significantly promotes the cytosolic release of cargos carried by exosomes, plasmids and liposomes, effectively enhances gene transfection efficiency, and drives gene knockdown of functional macromolecules (such as siRNA) in alveolar epithelial cells (with no significant cytotoxicity at effective concentrations). GALA serves as a critical tool for studies on lung cancer metastasis (e.g., melanoma lung metastasis) and lung-targeted drug delivery systems .

PEP1 is an amphipathic α-helical peptide containing 31 residues. The interaction of PEP1 with POPC-supported lipid bilayers (SLBs) is concentration-dependent: at low concentrations, it inserts into SLBs to generate compressive stress; at medium concentrations, it saturates the membrane surface to maintain constant stress; and at high concentrations, it solubilizes SLBs. PEP1 can be used for research on the mechanism of membrane-peptide interactions .
