Fingerprint of multiple sclerosis immune cells identified

Researchers at the University of Zurich have identified a cell population that likely plays a key role in multiple sclerosis (MS). T helper cells in the blood of MS patients infiltrate the central nervous system, where they ...

First step to induce self-repair in the central nervous system

Damaged peripheral nerves can regenerate after an injury, for example, following a forearm fracture. Axons, the long projections of neurons that transmit stimuli or signals to other cells, are affected in the case of injury ...
