A lipopeptide is a molecule consisting of a lipid connected to a peptide. Bacteria express these molecules. They are bound by TLR 2, which form a heterodimer with TLR6 or TLR1.
Certain lipopeptides are used as antibiotics.[1][2] Certain lipopeptides could have strong anifungtal and hemolytic activities.[3] It has been demonstrated that their activity is generally linked to interactions with the plasma membrane [4] and sterol components of plasma membrane could play a major role and can be their privileged partner of interaction.[5][6]
Examples
