LL-37 in Pseudomonas biofilms: adhesion and bacterial communication
Evidence level: Laboratory research
Research question
Can LL-37 influence biofilm formation without the outcome being explained solely by bacterial killing? The study uses Pseudomonas aeruginosa as a model.
Research model
Researchers measured biofilm formation, bacterial adhesion, and motility. Using gene expression analysis and additional tests, they investigated changes in bacterial communication.
What was found?
Under the conditions studied, LL-37 reduced biofilm formation. The authors linked this to reduced adhesion, altered motility, and effects on the Las and Rhl quorum-sensing systems.
Limitations and interpretation
A biofilm in a laboratory differs from an infection in a patient. Bacterial strain, growth medium, and test setup influence the outcome. Biofilm inhibition is not the same as a proven treatment for an existing infection.
