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 acts on it
Dectin-1 activates Syk in macrophages and is important for Dectin-1-stimulated reactive oxygen production but not for phagocytosis, Syk activation is restricted to a subpopulation of macrophages that is in equilibrium with cells that cannot activate the pathway, and the proportion of macrophages using this signalling pathway can be modulated by cytokine treatment, so Dectin-1 signalling reveals dynamic macrophage heterogeneity in inflammatory activation potential.
