(University of Pittsburgh) Inspired by a tactic cancer cells use to evade the immune system, University of Pittsburgh researchers have engineered tiny particles that can trick the body into accepting transplanted tissue as its own. Rats that were treated with these cell-sized microparticles developed permanent immune tolerance to grafts — including a whole limb — from a donor rat, while keeping the rest of their immune system intact, according to a paper published today in Science Advances.
