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
Induction of IL-2-receptor-positive lymphocytes was used as a functional zinc-thymulin readout; it is not equivalent to IL-2 secretion.

The human TEC study used induction of IL-2-receptor-positive lymphocytes as a functional readout. It also found that zinc–thymulin increased nuclear PKC activity in isolated lymphocyte nuclei **when IL-1 was present**, but not without IL-1. Keep the nuclear preparation, cytokine requirement and readout attached to that result. It does not establish an unconditional receptor → PKC → IL-2-production pathway in intact T cells.
