Werkingsmechanisme

Cetrorelix

Cetrorelix competitively and immediately blocks the pituitary GnRH receptor, rapidly suppressing LH and FSH release — without the initial hormone surge ('flare') of GnRH agonists.

LL-37

LL-37 is a cationic, amphipathic helical peptide and the only member of the cathelicidin family in humans. It is generated by proteolytic cleavage from the C-terminal portion of the precursor protein hCAP18 (CAP-18). Mechanistically it associates with and can permeabilize microbial membranes; in addition it modulates immune cells, influences cytokine release, exerts chemotactic activity, and can bind extracellular self-DNA. Preclinical models have described both anti-inflammatory and pro-inflammatory effects, depending on concentration and tissue context.

Frequently asked questions

What is the difference between Cetrorelix and LL-37?: Cetrorelix is classified as "Onderzoek (overig)", while LL-37 is classified as "Onderzoek (overig)". Cetrorelix: Cetrorelix is a synthetic decapeptide and GnRH antagonist. It is used in assisted reproduction (IVF) to prevent a premature LH surge during controlled ovarian stimulation. LL-37: LL-37 is the only known human cathelicidin, a 37-amino-acid antimicrobial peptide generated by cleavage of the precursor protein hCAP18. In research it plays a central role in innate immune defence and wound healing, yet acts in a context-dependent manner as both anti- and pro-inflammatory and has been linked to autoimmune processes. LL-37 is not an approved drug; the evidence base is predominantly basic and preclinical. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Cetrorelix or LL-37?: The highest available evidence level is "Humane RCT" for Cetrorelix and "Humane studie" for LL-37. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
What is the legal status of Cetrorelix and LL-37 in Germany and the United States?: Duitsland: Cetrorelix — Op recept, LL-37 — Alleen onderzoek. Verenigde Staten: Cetrorelix — Op recept, LL-37 — Alleen onderzoek. These are factual summaries with source and review date on the individual pages.
