Axonal and neuronal damage are commonly seen in patients with multiple sclerosis. Manuel A. Friese and his colleagues now report that the cation channel transient receptor potential melastatin 4 (TRPM4) is upregulated in multiple sclerosis lesions in patients and contributes to disease in vivo. Genetic deletion or pharmacological inhibition of TRPM4 in a mouse model of multiple sclerosis reduces clinical scores and is neuroprotective, suggesting this may represent a novel therapeutic target.
