Zooming-in on protein teamwork

(Goethe University Frankfurt) The surface of every cell contains receptors that react to external signals similar to a 'gate'. In this way, the cells of the innate immune system can differentiate between friend and foe partly through their 'toll-like receptors' (TLRs). Two parts of this gate often work together here, as researchers at Goethe University Frankfurt and their British colleagues have now found out with the help of a new super-resolution optical microscopy technique.
