Newco Vesalic Ltd. has formed to take forward research indicating extracellular vesicles secreted by skeletal muscle cells carry toxic payloads that are key drivers of motor neuron diseases, including amyotrophic lateral sclerosis. The discovery of this process, which is largely external to the brain and the central nervous system, has opened up new targeting possibilities, and Vesalic is now working on in vivo studies to demonstrate preclinical proof of concept.
