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.

    In isolated rat anterior pituitary tissue, picomolar zinc–thymulin stimulated ACTH, accompanied by cAMP changes and cGMP changes at higher tested concentrations. A cAMP-directed phosphodiesterase inhibitor enhanced some responses, whereas the cGMP-directed inhibitor attenuated responses at higher concentrations. LH increased at selected concentrations, **GH did not**, and prolactin decreased. This does not establish human cortisol elevation or blood–brain barrier passage.

  2. Thymulin increased prolactin release in a separate rat pituitary experiment, with a bell-shaped response and weaker effects in senescent preparations.

    Likewise, a separate study found **prolactin and TSH increases**, with a bell-shaped concentration response in incubation experiments, potentiation by TRH and cAMP-associated interventions, and weaker responses in senescent preparations. EGTA blocked release. The opposite prolactin directions across studies are an unresolved comparison involving concentration and preparation, not grounds to discard either result. TRH-like behavior does not establish binding to the TRH receptor. [1998 prolactin/TSH study](https://pubmed.ncbi.nlm.nih.gov/9818729/)
