What Does PBR Stand For?

PBR stands for Peripheral Benzodiazepine Receptor

PBR, or Peripheral Benzodiazepine Receptor, is a protein located predominantly in the outer mitochondrial membrane of various tissues, including the brain, immune system, and peripheral organs. It plays a critical role in the regulation of cellular functions such as steroidogenesis, apoptosis, and inflammation. PBR is also involved in the binding and transport of ligands, including certain benzodiazepines and other pharmacological agents, making it a significant target for research in neuropharmacology and the treatment of various disorders.
