Last reviewed 2026-07-03
Neuroimmune mediators are modeled as directional teaching nodes for threshold, reflex, sensory, vascular, and tissue-crosstalk behavior. Use as educational systems context, not diagnosis or treatment guidance.

Local map
Relationship field
Arrows point from the upstream source toward the receiving target. Restraint edges use a bar; association edges stay dashed because they are not causal arrows.
Selected relationship
Cholinergic inflammatory-reflex models restrain macrophage TNF output through alpha7 nicotinic receptor biology
Read as source restrains target activity or inflammatory output.
What this relationship means
Read this as a restraint edge: Vagal Acetylcholine is modeled as pushing Macrophage output downward or back toward control.
Effect of source
Vagal Acetylcholine is the regulating input.
Effect on target
Macrophage is the node whose inflammatory activity may be dampened.
Use with caution
Suppression means directional biology in this map, not guaranteed clinical improvement.
System effect
Vagal Acetylcholine restrains Macrophage; read the axes as the system domains being dampened or regulated.
Tolerance
Immune restraint, resolution, regulatory tone, or set-point control.
Inflammation
Inflammatory alarm, recruitment, mediator release, or tissue-damaging amplification.
Tissue
Organ, barrier, stromal, vascular, or local niche behavior.
Axes are mapped cues from Atlas data, not clinical predictions.
Evidence context
Curated edge, reviewed endpoints, and mapped external anchors.

Mediator interpretation
Effect Of and Effect On
Vagal acetylcholine represents the anti-inflammatory reflex side of neuroimmune biology. Atlas models it as a restraint signal that can dampen macrophage inflammatory cytokine output through alpha7 nicotinic receptor biology in appropriate contexts.
What this means
Effect of the nervous signal
Read vagal acetylcholine as a recovery and reflex-control signal: autonomic state can participate in immune restraint, not only immune activation.
Effect on immune and tissue systems
On immune systems it usually means macrophage cytokine output and inflammatory set points may be restrained in the right reflex context.
Use it in Atlas when
Use this node when a map needs to explain inflammatory recovery, parasympathetic tone, or gut-spleen-brain immune coupling.
Boundary
This does not turn heart-rate variability, vagal tone, or autonomic symptoms into a diagnosis or treatment selection tool.
Influence Trace
Nervous signal to immune behavior
What starts the signal?
Inflammatory challenge, recovery state, vagal activity, or autonomic reflex signaling.
What receives it?
Macrophage cytokine-output programs in inflammatory-reflex models, often taught through spleen-linked circuitry.
What changes in the system?
The system can move toward cytokine restraint and inflammatory set-point control.
What should not be over-interpreted?
Do not treat vagal tone, HRV, or autonomic symptoms as a diagnosis or a direct treatment-selection rule.
