Our recent autoradiography studies [39] in male rats after SCI, using a new translocator protein 18 kDa (TSPO) ligand [125I] IodoDPA-713 [72] (a new probe for imaging inflammation in clinical PET studies), revealed that cortex, thalamus, hippocampus, cerebellum, and caudate/putamen all showed chronic brain inflammation. The gene discussed is TSPO; the disease is brain inflammatory disease.
