Antimicrobial peptides span diverse structures and mechanisms; interpretable studies separate direct microbial effects from membrane damage, assay conditions and host-cell compatibility.
Mechanisms extend beyond one membrane model
Many antimicrobial peptides interact with microbial envelopes, but pore formation, surface disruption, translocation and intracellular targets can contribute differently across sequences and organisms. Mechanistic labels should be tied to direct evidence.
Assay conditions matter
Salt, medium composition, inoculum, growth phase, incubation time and peptide adsorption can shift apparent activity. Reporting these variables and using matched controls makes comparisons across experiments more defensible.
Selectivity and resistance questions
Microbial inhibition should be considered alongside mammalian-cell compatibility and stability in the test matrix. Serial exposure and mechanism studies can reveal whether an observed effect is robust or highly condition-dependent.
