Summary

LL-37 is the only cathelicidin-derived antimicrobial peptide found in humans: a 37-residue, amphipathic, helical peptide with a broad spectrum of antimicrobial activity. · pmid:16716248

Classification

It is expressed in epithelial cells of the skin, gut and airways and in white blood cells, and also regulates inflammation and attracts cells of the adaptive immune system. · pmid:16716248

Mechanism

The human gene encoding it (CAMP) is a direct target of the vitamin D receptor and is strongly induced by 1,25-dihydroxyvitamin D3. · pmid:15985530

Identity

PubChem CID 16198951: LL-37, C205H340N60O53, 4493 g/mol. · pubchem:16198951

CAS registry number 154947-66-7. · pubchem:16198951

Structure

No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for LL-37 yet.


Dose evidence, rung by rung

A studied human dose exists on file. Open the rung: the dose is the paper's, in its context, never PepJunkie's.

  1. Approved-label dose · a resolved regulatory document names a labelled dose

    nothing resolved on this rung

  2. Studied human doses · resolved human studies at the established tier
    • LL-37, the only human member of the cathelicidin family of antimicrobial peptides. · pmid 16716248 · 2006
  3. Observational evidence · resolved human data at the emerging tier: thin, or contested

    nothing resolved on this rung

  4. Community-reported protocols · protocol propositions from distinct members, counted once per human

    nothing resolved on this rung

  5. Preclinical evidence · resolved animal, cell or mechanistic work
    • Human cathelicidin antimicrobial peptide (CAMP) gene is a direct target of the vitamin D receptor and is strongly up-regulated in myeloid cells by 1,25-dihydroxyvitamin D3. · pmid 15985530 · 2005

2 resolved citations, 0 unresolved (an unresolved citation lends nothing). Community volume is its own rung and is never averaged into the evidence rungs.
