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

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.
