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.

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

  1. Thymic epithelial cells produce thymulin; metal-dependent antibody recognition must be distinguished from peptide quantity and biological activity.

    Thymic epithelial cells (TECs) are the established source. Production, secretion and metal-dependent activity should be represented as distinct processes. Antibody recognition of thymulin in TECs and serum also depends on the assay's sensitivity to metal-associated conformation. [TEC and antibody study](https://doi.org/10.1073/pnas.82.20.7035)

Where it participates (unsigned role)

  1. IL-1 alpha and IL-1 beta increased zinc uptake in cultured human thymic epithelial cells; part of the response was independent of proliferation.

    In cultured human TECs, **IL-1α and IL-1β increased zinc uptake, metallothionein mRNA and secretion of biologically active thymulin**. Part of the IL-1 effect on zinc uptake occurred independently of proliferation. Metallothionein was proposed as an intracellular zinc donor; direct transfer from a defined metallothionein molecule to FTS was not resolved by these observations. Do not turn that proposal into an established transfer reaction. [Coto et al., 1992](https://doi.org/10.1073/pnas.89.16.7752)
