Iterative design and evaluation of membrane-targeting functional peptides has yielded molecules that can modulate membrane barrier function, lipid packing, and structure with refined specificity.
3 membrane functions targetedDesigned peptides can modulate membrane barrier function, lipid packing, and structure — key properties for drug delivery and antimicrobial applications
What the researchers found
Iterative peptide design yielded functional peptides with refined ability to modulate biomembrane barrier function, lipid packing, and structure.
Why it matters
Many diseases involve membrane dysfunction, and many drugs need to cross membranes. Peptides that precisely control membrane properties could improve drug delivery, fight infections, and potentially treat membrane-related diseases.
