"Nerve injury-induced neuropathic pain was enhanced in spinal cord-specific GLT1 knockout mice but alleviated in periaqueductal gray (PAG)-specific GLT1 knockout mice. In addition ceftriaxone upregulated GLT1 expression in the spinal cord but not the PAG of control mice and attenuated tactile hypersensitivity in nerve-injured control mice but not in nerve-injured spinal cord-specific GLT1 knockout mice."xsd:string
