After all, how do these extra cellular vesicles fight? Extra cellular vesicles cannot divide like cells, but are like smaller versions of cells specifically designed to contain and kill viruses. Rhinologist Dr. Benjamin Blair, an associate professor at Harvard, said that the extracellular vesicles act as decoys. So when we inhale the virus, the virus instead of sticking to the cells, sticks to these decoys. In a research, it was found that when viruses attack the nose, the production of EV cells increases by up to 160%.
