Stage 1

Priming signal

advanced

Trigger

TLR ligands, TNF-alpha, IL-1, tissue necrosis, or chronic metabolic stress.

Tissue Context

Macrophages and monocytes increase NF-kB-dependent inflammatory readiness.

Cells

macrophagesmonocytesdendritic cells

Signals

TNF-alphaNF-kBpro-IL-1beta

State Shift

The cell becomes competent to produce inflammasome cytokines.

Clinical Pattern

Low-grade inflammatory tone, CRP/IL-6 context, malaise or pain sensitivity.
