CHART CLUE

The inflammasome is intracellular, pyrin lives in neutrophils, and microtubules – colchicine’s target – are part of the cytoskeleton. The transport half of the module finally explains Stina’s swelling, how an ion channel can trigger inflammation, and how a pump handles colchicine.

Deep in the neutrophil are mitochondria (power), lysosomes and peroxisomes (cleanup), and the cytoskeleton (structure and movement). Among the cytoskeleton are microtubules – the rails the cell crawls along. Those microtubules are exactly what colchicine jams, which is why an ancient plant alkaloid still calms Stina’s attacks.

From Stina’s chart: She later learned her eventual medication, colchicine, comes from the autumn crocus and has calmed inflammation for centuries. Something that old, working that well, hinted her problem was simpler than “stress.”

Other organelles don’t move the cell – they build its proteins. Including pyrin itself.
