Component
Particle size of a glucan preparation
Particle size of a glucan preparation. Species, exposure and limitations are retained in each linked claim.
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.
What it acts on
Beta-glucans differ greatly in size, structure and ability to activate effector immune responses from dendritic cells and small particulate beta-glucans are thought to be poor activators of innate immunity, and large beta-glucan-stimulated human dendritic cells generate significantly more IL-1beta, IL-6 and IL-23 compared to those stimulated with the smaller beta-glucans, while in marked contrast the secretion of TSLP and CCL22 were found to be insensitive to beta-glucan particle size, with the capacity to induce phagocytosis and the relative IL-1beta production determined by beta-glucan size regulating the composition of the cytokine milieu.
