Defensins and LL-37: a review of function in the gingival epithelium.
Greer. Ara A; Zenobia. Camille C; Darveau. Richard P RP
Key Findings
- LL‑37 and defensins act as natural antibiotics in the gingival epithelium
- They also attract immune cells and help maintain tissue balance
- Their activity varies depending on where they are in the oral lining
Practical Outcomes
- For biohackers, the main takeaway is that supporting oral innate immunity (e.g., good oral hygiene, possibly using agents that boost natural peptide production) may aid overall health, but the paper doesn’t give specific dosing or supplement protocols for LL‑37.
Summary
This review explains that LL‑37 and other antimicrobial peptides help protect the gums by killing bacteria and also by guiding immune cells, keeping the mouth’s lining healthy. It mainly describes how these proteins work in the gum tissue, not new ways to use them as supplements.
Abstract
Antimicrobial peptides represent an important aspect of the innate defense system that contributes to the control of bacterial colonization and infection. As studies have progressed it has become clear that antimicrobial peptides manifest other functions in addition to their antimicrobial effects. These functions include chemotaxis of numerous types of host cells involved in both the innate and adaptive immune responses. In this review, the antimicrobial activity, the regulation and the contribution to host homeostasis of alpha-defensins and LL-37, as well as of beta-defensins, are discussed in the context of their specific tissue locations in the junctional epithelium and oral epithelium, respectively.
