A study led by Imperial College London has shown for the first time it is possible to help prevent organ rejection using a novel strategy that redirects the bodys immune response instead of suppressing it.
Writing in the Journal of Clinical Investigation today, researchers from the University of Cambridge, the University of Edinburgh, Lorantis Ltd and Imperial demonstrate that it is possible in mice to alter whether T white blood cells specialise to attack foreign tissue and thus cause rejection, or instead become part of the bodys peacekeeping force, which patrols the body, defending against attack.
Unlike current therapies, which leave patients vulnerable to infection by inducing non-specific immunosuppression, this new approach targets a key cellular signal known as Notch, which the researchers found acts as a gatekeeper by governing how immune cells specialise.

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
