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.

Systems profile
System effects
Primary mapped axes from existing Atlas data.
Tissue
Organ, barrier, stromal, vascular, or local niche behavior.
Inflammation
Inflammatory alarm, recruitment, mediator release, or tissue-damaging amplification.
Metabolism
Energy allocation, glycolysis, mitochondrial strain, lipid signaling, or nutrient-sensitive behavior.

Cytokine ecology
Signal Role
TNF-alpha is a core inflammatory cytokine that activates endothelium, recruits leukocytes, and can drive cachexia and tissue destruction when sustained.
Pathway
Source Cells
Target Cells
Inflammatory Role
Amplifies adhesion, cytokine cascades, fever, pain sensitivity, and tissue-destructive inflammation.
Regulatory Role
Supports granuloma maintenance and pathogen containment when appropriately localized.
