Component
Avermectin
Parent macrocyclic lactone family from which ivermectin is derived; findings recorded against avermectin are not interchangeable with ivermectin.
2 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What it acts on
Avermectin inhibited NF-kappa-B p65 translocation into the nucleus and inhibited JNK and p38 phosphorylation in lipopolysaccharide-stimulated mouse macrophages.
Experimental context and source evidence
- duration
- 30 minutes after lipopolysaccharide
- evidence_access
- Primary PubMed abstract and indexed metadata reviewed. Full-text method details not stated here remain unresolved.
- experimental_model
- Mouse RAW 264.7 macrophages
- exposure
- Avermectin 0.625, 1.25 or 5 mg/L for one hour before 1 mg/L lipopolysaccharide
- limitations
- The compound tested was avermectin, the parent macrocyclic lactone, not ivermectin, and tumour necrosis factor alpha, interleukin-1 beta and interleukin-10 were regulated while interleukin-6 was not significantly affected.
