Neutrophil Chemotaxis & NETosis

Interactive 3D immune-response simulator: neutrophils sense a chemokine concentration gradient rising from an infection site, chase it down with a biased random walk, phagocytose bacteria one at a time, and release neutrophil extracellular traps (NETs) when overwhelmed by local bacterial density.

Watch the first line of innate immune defense in action: neutrophils sense a chemokine gradient rising from a bacterial infection site, navigate up it with a physically grounded biased random walk, and destroy bacteria one at a time by phagocytosis. When a neutrophil is swarmed by more bacteria than it can individually engulf, it triggers NETosis — rupturing to release a sticky extracellular trap that immobilises everything nearby. Tune infection severity, recruitment rate, chemotactic sensitivity and the NETosis threshold, and watch the live counts of bacteria, active neutrophils, NETs and total kills respond in real time.
