Provenance layer
External context
Curated external IDs add pathway and protein context around Atlas content. They do not update the graph automatically and they are not patient-specific interpretation.
State signature
Systems profile
System effects
Primary mapped axes from existing Atlas data.
Chronicity
Memory, priming, fibrosis, exhaustion, remodeling, or other time-dependent drift.
Tissue
Organ, barrier, stromal, vascular, or local niche behavior.
Metabolism
Energy allocation, glycolysis, mitochondrial strain, lipid signaling, or nutrient-sensitive behavior.
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
Activated naive B cells can enter germinal-center reactions with Tfh help
Read as source supporting or biasing the target state.
What this relationship means
Read this as Naive B Cell influencing Germinal Center B Cell; the arrow names the direction, while the details explain the likely system domain.
Effect of source
Naive B Cell is the upstream signal or context.
Effect on target
Germinal Center B Cell is the receiving node whose behavior may shift.
Use with caution
Use this as a map-reading aid, not as diagnosis, triage, treatment guidance, or a risk score.
System effect
Naive B Cell influences Germinal Center B Cell; the axes below show which mapped systems carry that relationship.
Inflammation
Inflammatory alarm, recruitment, mediator release, or tissue-damaging amplification.
Tissue
Organ, barrier, stromal, vascular, or local niche behavior.
Chronicity
Memory, priming, fibrosis, exhaustion, remodeling, or other time-dependent drift.
Axes are mapped cues from Atlas data, not clinical predictions.
Evidence context
Curated edge, reviewed endpoints, and mapped external anchors.

Network behavior
Systems Overview
Naive B cells carry a unique BCR and require antigen, survival signals, and often T-cell help to become memory, plasma, or germinal-center cells.

Metabolic State
Programs
Acute: BCR engagement increases antigen presentation and activation readiness.
Chronic: Repeated weak self-antigen exposure can create anergy or autoreactive risk when checkpoints fail.
Tissue Roles
lymphoid: Follicular antigen scanning and T-cell interaction.
gut: Can enter IgA-associated mucosal programs after priming.
lung: Supports local antibody responses during infection or tertiary lymphoid formation.
skin: Usually secondary unless autoantibody or ectopic lymphoid patterns emerge.
Disease Associations
Clinical Pearls
- Naive B cells are the substrate for vaccine response quality.
- B-cell number is less informative than maturation and functional antibody response.
- Tolerance checkpoints prevent useful diversity from becoming autoreactivity.
