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 .

GALA-Cys is a chemically modified GALA peptide (HY-P5423) that retains GALA functions while acquiring strong covalent conjugation capability. GALA-Cys undergoes pH-driven reversible secondary structure transition, rearranges into an amphipathic α-helix, self-oligomerizes, penetrates lipid membranes to form pores, and disrupts lipid bilayers, thereby enabling endosomal escape and cytosolic cargo delivery. GALA-Cys can be conjugated with lipid DPTE for integration into liposomes, self-assembles into a tilted monolayer on gold surfaces, and serves as a pH-responsive coating for particle surface functionalization. GALA-Cys is applicable to studies related to targeted cargo delivery .
