Centrally expressed Cav3.2 T-type calcium channel is critical for the initiation and maintenance of neuropathic pain.

Cav3.2 T-type calcium channel is a major molecular actor of neuropathic pain in peripheral sensory neurons, but its involvement at the supraspinal level is almost unknown. In the anterior pretectum (APT), a hub of connectivity of the somatosensory system involved in pain perception, we show that Cav3.

Ethosuximide improves chronic pain-induced anxiety- and depression-like behaviors.

Chronic pain is a heavy burden disease. Current treatments are generally weakly effective or associated with adverse effects. New therapeutic approaches are therefore needed.
