Hypothesis
More inhibitors are present in human skin that regulate KLK5 activity.
Conclusion
LEKTI-2 is a specific inhibitor of KLK5 and plays a role in the regulation of skin desquamation.
Supporting Evidence
- LEKTI-2 was found to specifically inhibit KLK5 but not other serine proteases.
- Spink9 mRNA was detected in human skin samples and cultured keratinocytes.
- LEKTI-2 expression was increased at sites of plantar hyperkeratosis.
Takeaway
Scientists found a new protein in human skin that helps control skin shedding by stopping a specific enzyme.
Methodology
The study involved purifying a KLK5-inhibiting peptide from human skin and analyzing its expression and inhibitory activity.
Limitations
The study's findings are preliminary and require further validation in larger samples and different skin types.
Participant Demographics
Healthy individuals' skin samples were used for the study.
