A role for leucine-rich, glioma inactivated 1 in regulating pain sensitivity.

ABSTRACT: Neuronal hyperexcitability is a key driver of persistent pain states, including neuropathic pain. Leucine-rich, glioma inactivated 1 (LGI1) is a secreted protein known to regulate excitability within the nervous system and is the target of autoantibodies from neuropathic pain patients. Therapies that block or reduce antibody levels are effective at relieving pain in these patients, suggesting that LGI1 has an important role in clinical pain. Here we have investigated the role of LGI1 in regulating neuronal excitability and pain-related sensitivity by studying the consequences of genetic ablation in specific neuron populations using transgenic mouse models. LGI1 has been well studied at the level of the brain, but its actions in the spinal cord and peripheral nervous system are poorly under
