Similarly, antimicrobial peptides (AMPs) derived from microorganisms, particularly short peptide bacteriocins (SPBs) and quorum sensing inhibitory peptides (AIPs) produced by symbiotic bacteria, hold significant therapeutic potential in AD treatment by selectively inhibiting the growth and virulence of S. aureus, modulating skin immune responses, and restoring skin microbiota balance (16). Here, ADSL is linked to Alzheimer disease.
