System effects
Primary mapped axes from existing Atlas data.
Tissue
Organ, barrier, stromal, vascular, or local niche behavior.
Tolerance
Immune restraint, resolution, regulatory tone, or set-point control.
Chronicity
Memory, priming, fibrosis, exhaustion, remodeling, or other time-dependent drift.
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
Antigen presentation with costimulation and cytokine context
Read as source increases target activity, recruitment, or threshold crossing.
What this relationship means
Read this as Dendritic Cell influencing T Cell Subsets; the arrow names the direction, while the details explain the likely system domain.
Effect of source
Dendritic Cell is the upstream signal or context.
Effect on target
T Cell Subsets 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
Dendritic Cell influences T Cell Subsets; 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.
Metabolism
Energy allocation, glycolysis, mitochondrial strain, lipid signaling, or nutrient-sensitive behavior.
Axes are mapped cues from Atlas data, not clinical predictions.
Evidence context
Curated edge, reviewed endpoints, and mapped external anchors.

Network behavior
Systems Overview
Dendritic cells sample tissue, integrate danger and tolerance cues, migrate to lymphoid niches, and present antigen in a way that shapes T cell fate.
Lineage
Origin
HSC -> myeloid or lymphoid DC progenitors -> cDC1, cDC2, pDC, monocyte-derived DC states
Transcription factors: BATF3, IRF8, IRF4, ZEB2, E2-2

Programs
Acute: Danger cues increase costimulation, cytokines, migration, and T cell priming.
Chronic: Persistent antigen can create tolerogenic, exhausted, or inflammatory DC programs.
Tissue Roles
gut: Balances oral tolerance, microbial sampling, IgA support, and TH17/Treg differentiation.
lung: Samples inhaled antigen and directs allergy, viral defense, or tolerance.
skin: Langerhans and dermal DCs coordinate barrier antigen responses.
lymphoid: Presents antigen and costimulation to naive T cells.
Disease Associations
Clinical Pearls
- Dendritic cells determine whether antigen becomes memory, tolerance, allergy, or autoimmunity.
- Costimulation and cytokine context are as important as antigen identity.
- Vaccines work by engineering dendritic cell context.
