The primary mode of action for many antimicrobial peptides involves directly targeting and disrupting the microbial cell membrane. This can occur through various pathways, including pore formation. For instance, some AMPs attack bacterial membranes by forming pores in the outer membrane, leading to cell lysis. The peptides need to span the lipid bilayer in order to stabilize the pore, a process that is influenced by factors such as peptide length. This membrane disruption and inhibition of critical cellular processes effectively kills bacteriaMode-of-Action of Antimicrobial Peptides: Membrane .... Research by Yeaman and colleagues (2003) highlights the sophisticated and dynamic mechanisms of action employed by many antimicrobial peptides to achieve rapid and potent activities.

Beyond membrane disruption, antimicrobial peptides can also exert their effects by entering bacterial cells to interact with intracellular components. This includes targeting nucleic acids and protein biosynthesis, as explored by Le et al. (2017). Furthermore, AMPs can inhibit essential cellular processes, such as protein folding or enzyme activity, as noted by Bechinger (2017). This multifaceted approach means that the mechanism of action of AMPs varies depending on their target cells' specificity, the antimicrobial peptide concentration, and the specific microbial characteristics.

Intracellularly, they can interfere with viral replication processes. This underscores the versatility of antimicrobial peptides in combating various infectious agents.

The efficacy of antimicrobial peptides is intrinsically linked to their physicochemical properties. AMP's mechanism is dependent on the number of physicochemical properties including the sequence of amino acids, charge, amphipathic property, and more. These properties dictate how the peptides interact with microbial membranes and intracellular targets. For example, cationic antimicrobial peptides (CAMPs) play a significant role in host defense against microbial infection due to their positive charge, which facilitates interaction with the negatively charged microbial membranes作者：R Dilawari·2025·被引用次数：4—Vesicle protrusion induced byantimicrobial peptidessuggests common carpetmechanismfor short antimicrobial peptides.
