New PET-Probe Allows Imaging of Immune System

"The probe is based on a fundamental cell biochemical pathway called the DNA salvage pathway, which acts as a sort of recycling mechanism that helps with DNA replication and repair. All cells use this biochemical pathway to different degrees. But in lymphocytes and macrophages, the cells of the immune system that initiate immune response, the pathway is activated at very high levels. Because of that, the probe accumulates at high levels in those cells, said the study's senior author, Dr. Owen Witte, a researcher at UCLA's Jonsson Cancer Center and a Howard Hughes Medical Institute investigator.
