Imaging Glutamate Fluctuations with [(11)C]ABP688: A GLT-1 Challenge with Ceftriaxone

This research explores the use of molecular imaging to investigate dynamic changes in glutamate levels in the brain, an important neurotransmitter involved in various brain functions. The study utilized [(11)C]ABP688, a positron emission tomography (PET) ligand that binds to the allosteric site of the metabotropic glutamate receptor type 5 (mGluR5). The researchers administered ceftriaxone (CEF), an activator of the GLT-1 transporter (EAAT2) that is known to decrease extracellular glutamate levels. They observed that CEF administration increased [(11)C]ABP688 binding potential (BP(ND)) in the thalamic ventral anterior (VA) nucleus, consistent with a decrease in extracellular glutamate levels. This study demonstrates the potential of [(11)C]ABP688 PET imaging for studying glutamate fluctuations in the brain, offering a valuable tool for investigating the role of glutamate in neurological and psychiatric disorders.
