Component
Human cathelicidin precursor hCAP18
Study-defined Human cathelicidin precursor hCAP18. Read each linked record for species, exposure and endpoint.
1 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.
Where it participates (unsigned role)
TLR activation coupled vitamin D pathway induction to cathelicidin expression and killing of intracellular M. tuberculosis in the human macrophage experiments.
Experimental context and source evidence
- cross_nutrient
- false
- experimental_model
- Human monocyte/macrophage TLR stimulation and intracellular mycobacterial assay
- exposure
- Cultured human macrophages with intracellular M. tuberculosis.
- limitations
- Cellular experimental result, not a human tuberculosis-treatment trial; infection response depends on more than vitamin D.
- nutrient_topic
- Vitamin D2 and D3 research collection; topical membership is not evidence of a direct dietary effect. · Vitamin D2 and D3
- organism
- Homo sapiens
