Component
Calcium entry in rat pinealocytes
Context-specific entity; species, compartment and exposure are stated on each claim.
2 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 acts on it
D-aspartate at 1 mM increased intracellular calcium in 11 of 13 tested rat pinealocytes; NMDA, AMPA and kainate did not evoke this response in the reported panels.

Complete structured claim and evidence
Where it participates (unsigned role)
The study reported D-aspartate-evoked glutamate secretion with blocker sensitivity similar to L-aspartate, supporting calcium-dependent vesicular release downstream of transport.
Experimental context and source evidence
- evidence_access
- Primary full text; supplementary result described in main text
- experimental_model
- Rat pinealocytes; HPLC and calcium/exocytosis experiments; D-form comparison reported in supplemental results.
- limitations
- Main figures often use L-aspartate. Direct D-aspartate binding to inhibitory metabotropic receptors was not established.
- nutrient_topic
- D-Aspartate collection; species, compartment, exposure, co-substrates and manipulation remain explicit. · D-Aspartate
- plain_language
- An aspartate signal can release another signaling amino acid.
