Results from this study2

No result from this study comes from a test of the peptide.

Natural levels measured2

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    LL‑37 was expressed in palatine tonsils from control subjects and recurrent acute tonsillitis patients, in all 26 tonsil samples.

    In plain wordsThe body's own LL‑37 was found in all tonsil samples from healthy people and people with repeated tonsillitis.

    Summary
    Using molecular analyses, the palatine tonsils from control and recurrent acute tonsillitis subjects were confirmed as a site of expression of the antimicrobial cationic peptides human beta-defensin 1-3, LL-37 (cathelicidin) and Liver expressed antimicrobial peptide-1 (LEAP-1).

    Summary · context
    Our analyses indicated that all six antimicrobial cationic peptides were expressed in all 26 tonsil samples.
    Summary · context
    Palatine tonsils were harvested with informed consent from 19 recurrent acute tonsillitis patients and from five control subjects undergoing tonsillectomy for sleep disorders.

    This result measures the body's own LL-37. Nobody was given the peptide. It is not evidence about taking it.

  2. 02HumanEndogenous levelObservational studyOther

    The surface epithelium of tonsils from recurrent acute tonsillitis patients showed reduced amounts of LL‑37 compared with healthy controls.

    In plain wordsTonsils of people with repeated tonsillitis had less of the body's own LL‑37 on the surface than healthy tonsils.

    Summary
    However, the surface epithelium of tonsils from recurrent acute tonsillitis patients showed reduced amounts of antimicrobial peptides human beta-defensins 1 and 3, and LL-37, compared with healthy controls.
