Reading single vesicles: a blood test learns to find where inflammation starts

Chronic inflammation drives diseases from arthritis to heart failure, but pinpointing where in the body it starts is guesswork. Nagoya University researchers have built a technique that reads extracellular vesicles — the tiny parcels cells shed into blood and urine — one at a time, checking both the proteins on a vesicle's surface and the microRNA messages inside it, without destroying the parcel. Because each organ's vesicles carry a signature, reading them together reveals spatial patterns that point back to the tissue where inflammation began. The work, published in Cell Reports Physical Science, turns a routine blood or urine sample into something closer to a return address for disease.
