Cells as dynamic state machines

Sentinel tissue amplifier for barrier defense, allergy, repair, and neuroimmune sensing

Short-lived innate responder that converts danger gradients into oxidative and proteolytic containment

Tissue-adapted interpreter of debris, pathogens, metabolism, repair, and chronic inflammatory memory

Adaptive decision layer for specificity, memory, tolerance, cytotoxicity, and chronic exhaustion

Antigen-inexperienced helper precursor that becomes TH1, TH2, TH17, Tfh, Treg, or memory depending on context

IFN-gamma-producing helper state for intracellular pathogens and macrophage activation

Type 2 helper state coordinating IgE, eosinophils, mast cells, mucus, and barrier remodeling

Barrier helper state that recruits neutrophils and protects against extracellular bacteria and fungi

FOXP3-positive tolerance cell that restrains activation thresholds and supports resolution

Germinal-center helper cell that instructs class switching, affinity maturation, and B-cell memory

Antigen-specific killing cell for viral control, tumor surveillance, memory, and exhaustion biology

Type 2 granulocyte linking parasite defense, allergy, epithelial injury, and repair signaling

Circulating type 2 granulocyte linking IgE, IL-4, parasites, allergy, and early TH2 amplification

Circulating myeloid bridge between marrow demand, inflammation, macrophages, and dendritic-like states

Innate cytotoxic lymphocyte for viral defense, tumor surveillance, missing-self sensing, and cytokine production

Tissue-resident innate lymphocyte family that mirrors helper T-cell programs without antigen-specific receptors

Antigen-context translator that decides priming, tolerance, and adaptive immune direction

Adaptive humoral cell linking antigen recognition, germinal centers, antibody class, and immune memory

Antigen-inexperienced B cell that scans follicles and can enter extrafollicular or germinal-center responses

Rapidly adapting B-cell state for affinity maturation, class switching, selection, and memory quality

Long-lived recall cell preserving antigen experience and enabling rapid secondary antibody responses

Antibody-secreting terminal B-cell state with unfolded-protein and survival-niche demands

IL-10-leaning B-cell state that restrains inflammation and supports tolerance networks

CNS-resident macrophage lineage controlling synapses, injury response, sickness signaling, and neuroinflammation

Local immune-state category for resident memory, macrophage, mast-cell, ILC, plasma-cell, and stromal-immune niches
