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 acts on

  1. In the four-man normal-diet experiment, the intermediate-antagonist subject developed gastrointestinal and neurological symptoms, while the highest-exposure subject had mainly a transient tremor; the control and lowest-exposure subject remained relatively well.

    One control; three men received escalating antagonist regimens, up to 2–4 g/day in the highest-exposure subject; pantothenic acid 4 g/day was later given after antagonist withdrawal.

    Pharmacological antagonist exposure with an otherwise normal diet, not dietary B5 deprivation. Very small sample and concurrent antagonist withdrawal prevent isolating a pure vitamin-rescue effect. The interindividual pattern is not a monotonic dose-response or a direct assay of a specific PANK isoform.

Where it participates (unsigned role)

  1. The 1958 depletion study found an impaired eosinopenic response to ACTH, while urinary 17-ketosteroid excretion remained normal; the authors did not interpret this pattern as sufficient evidence of adrenal cortical hypofunction.
